The BMW 2 Series Convertible is the third model in the company‘s 2 Series line-up and comes to market as a direct replacement for the 1 Series Convertible – a vehicle that was the most successful car in its class with global sales of more than 130,000 units.
The new car will initially be available with a choice of four engines, including a new 2.0-litre diesel for the 220d and, for the first time in a BMW convertible, an M Performance variant, the M235i. Fuel economy improvements over the previous model average 18 per cent. The 2 Series Convertible also brings significant improvements in passenger space and access, acoustic comfort, style, dynamism and equipment, while the ConnectedDrive services for the first time include wireless updating of navigation data.

More open-top driving pleasure with an added dash of style
The BMW 2 Series Convertible is longer (by 72mm) and wider (by 26mm) than the model it replaces, and has a wheelbase which has been elongated by 30mm. These increases have been put to good use to enhance passenger access and space, increase driving enjoyment with the roof down and change the proportions so that BMW’s latest compact convertible looks even more stylish.
The electrically operated folding soft top lowers or raises in just 20 seconds at the touch of a button, and can be carried out at speeds of just over 30mph. Additional insulation in the skin of the soft-top improves acoustic comfort, with a 4db noise reduction, and adds to the year-round usability of the car. Improved aerodynamics, with a Cd of just 0.31, also helps to make the cabin quieter. An easier-to-use optional wind deflector provides greater protection against turbulence when travelling top-down.
Once folded, the soft top disappears fully into the boot to give the BMW 2 Series Convertible a premium ‘boat deck’ appearance. Luggage capacity increases by 30 litres to 335 litres, making it the largest boot in its class. A through-loading system is optionally available to increase versatility.
The four-seat interior, with folding rear bench, provides greater space and a more intense open-top driving experience, placing the occupants in a typical BMW set-back position. Rear access benefits from an 11mm wider aperture when the front seats are tilted forwards. Large door pockets, a spacious glovebox, a central storage compartment and two cup holders provide improved in-cabin storage.
The stretched silhouette of the BMW 2 Series Convertible emphasises the tell-tale BMW design characteristics of a long bonnet and wheelbase, short overhangs and a rear-biased cabin. The double kidney grille leans slightly forwards between twin-round circular headlights that narrow towards the centre, replicating the outlines of the lower air intakes. An LED accent light cuts across the top of the lighting unit on the optional Xenon headlights, while Adaptive Headlights featuring Selective Beam technology are also available. Air Curtains in the front apron channel air to outlets in the front side panels, reducing turbulence in the wheel arches to enhance fuel efficiency.
The track widths of the BMW 2 Series Convertible are larger than those of its predecessor, by 41mm at the front and 43mm at the rear, so that the widest part of the car is the rear wheel arch area. This emphasises the greater dynamism of the new model and its unique-in-class rear-drive layout. Horizontal lines at the rear also hint at the car’s wider stance. The rear lights extend into the side panels and feature familiar BMW L-shaped LED light bars. At the sides, a slightly rising shoulder line, swage lines running through the door handles and character lines from the doors and side skirts to the rear panels all point to the car’s sporty, rear-wheel-drive layout.
The interior has been deliberately kept as simple as possible, with layered surfaces, driver-focused controls, clear instruments and a Sport or M Sport leather-covered multi-function steering wheel. Controls for the audio and climate control systems are set against High-gloss Black surfaces and the air vents have chrome surrounds. Switchable ambient lighting is further confirmation of the car’s premium quality. The BMW iDrive controller, linked to a 6.5-inch display screen, gives access to the car’s control systems with minimum distraction.
A more rigid body and advanced new safety features for greater protection
The BMW 2 Series Convertible delivers enhanced safety for occupants and pedestrians compared with the previous model through a combination of a more rigid body and advanced safety features. Torsional stiffness has been raised by 20 per cent and bending stiffness is 10 per cent higher, despite a decrease in body weight, thanks to extensive use of high- and ultra-high-strength steels.
The A-pillars with strengthening elements and joints made from hot-formed steel combine with the aluminium bars hidden behind the rear seats to form a survival space for occupants in the event of a roll-over accident. The roll-over bars are triggered automatically in fractions of a second if the car’s electronic sensors detect any risk. Strong supporting structures, precisely defined load paths, large deformation zones and intelligent restraint systems ensure that the BMW 2 Series Convertible meets or surpasses safety requirements around the world. Meanwhile, an active bonnet which rises at the rear and contains special deformation areas provides optimum pedestrian protection.
The car’s restraint systems include front airbags, side airbags with head airbags integrated into the seat backrests, seatbelt pre-tensioners and force limiters in the front seats and ISOFIX child-seat attachment points in the rear. Also standard is a Tyre Pressure Monitoring system which registers any loss of pressure and activates a signal in the instrument cluster to warn the driver.
Greater performance and dynamism with improved efficiency
Four BMW TwinPower Turbo engines featuring a suite of EfficientDynamics technologies endow the BMW 2 Series Convertible with superior performance to its predecessor, with an average 18 per cent improvement in fuel efficiency and lower CO2 emissions. The engines include a new 2.0-litre diesel for the 220d and, for the first time in a BMW convertible, an M Performance power unit for the M235i. There are also two 2.0-litre petrol engines available, the 220i and 228i. All are more powerful than the engines in the previous model and meet EU6 emissions standards.
The new 2.0-litre diesel engine develops 14hp and 50Nm of torque more than the previous unit, with greater efficiency. The combined fuel economy is 60.1mpg with the six-speed manual transmission or 64.2mpg with the eight-speed automatic gearbox which is optional on every model, while the respective CO2 emissions are 124g/km and 116g/km. It features an aluminium crankcase with thermally joined liners to reduce internal friction, and balancer shafts to eliminate vibrations. An enhanced turbocharger and an improved common-rail direct-injection system operating at up to 2,000 bar raise efficiency, and the engine is also lighter and quieter than its predecessor.
The M Performance 3.0-litre six-cylinder engine in the M235i develops 326hp and 450Nm of torque from only 1,300rpm with the aid of twin-scroll turbocharging, high-precision centrally positioned multi-hole direct injectors, VALVETRONIC variable valve timing and Double-VANOS variable camshaft timing. The result is an infectious cocktail of high-revving ability, responsive power, instantaneous torque and sports car performance with the utmost efficiency. Acceleration from zero to 62mph is achieved in 5.2 seconds with the manual gearbox and 5.0 seconds with the automatic, yet combined fuel economy is 33.2mpg in the manual and 35.8mpg in the automatic, while CO2 emissions are 199g/km and 184g/km respectively.
This efficiency is due in no small part to the extensive EfficientDynamics features on every model. These include lightweight body engineering, sleek aerodynamics with Air Curtains at the front, Auto Start-Stop, Brake Energy Regeneration and an ECO PRO mode within the standard Driving Experience Control system. This can reduce fuel consumption by up to 20 per cent by modifying accelerator and engine management responses, putting the climate control system into its most efficient setting and even giving the driver tips on how to drive economically through the Proactive Driving Assistant with the BMW Professional navigation system.
The longer wheelbase, increased track widths and stiffer body of the BMW 2 Series Convertible, allied to the latest driver assistance systems, ensure that the driving experience has been raised to even greater levels. The car has the typical sporty agility of a rear-drive BMW with an ideal front-to-rear weight distribution, combined with exceptional comfort. The double-joint tie-bar front suspension with spring struts and five-link rear axle have been precision-tuned for the BMW 2 Series Convertible.
The standard electronic assistance systems include Dynamic Stability Control; incorporating Anti-lock Braking, Dynamic Traction Control, Cornering Brake Control and Dynamic Brake Control. These are supported by Brake Assist, Fading Compensation, Brake Drying, the Start-Off Assistant and the Active Differential Brake. The car can also be specified with either M Sport or Adaptive M Sport suspension and M Sport braking system.
The M Sport suspension and braking system, with model-specific tuning, are standard on the 228i and M235i, which also has custom-tuned Variable Sport steering. The suspension set-up and damping of the range-topping model takes into account, not only its exceptional performance, but also the characteristics introduced by its soft roof. Options include a BMW M Performance limited-slip differential.
ConnectedDrive now with free wireless navigation updates
The BMW 2 Series Convertible can be fully connected with the outside world through a wide range of standard-fit and optional ConnectedDrive features. They include, for the first time on any BMW, a new Professional navigation system which updates navigation data free and wirelessly through the built-in SIM card. This is capable of supporting the LTE (Long Term Evolution) wireless standard, which is up to five times faster than 3G.
Every BMW 2 Series Convertible comes with Bluetooth hands-free telephone connectivity with audio streaming and a USB interface, a DAB tuner, BMW Emergency Call and BMW TeleServices as standard. These can be supplemented with BMW Navigation or Professional multimedia system, Internet connectivity, BMW Online Services, Online Entertainment, Real Time Traffic Information, enhanced Bluetooth with Voice Control, Remote Services and Information Plus.
Customers can also specify the Driving Assistant with camera-based Lane Change and Lane Departure warning systems. It also features Attention Assistant to alert a potentially drowsy driver. Collision Warning primes the brakes and alerts the driver if the 2 Series Convertible gets too close to the car in front. Rear Park Distance Control is standard, and can be supported with Park Distance Control at the front as part of the Driver Comfort package. A Reversing Assist camera is also offered.

The BMW 2 Series Convertible is on sale from 28 February, 2015. It will be priced from £29,180 OTR for a 220i Sport Convertible.
- Style and dynamics of the acclaimed BMW 2 Series Coupe combined with open-air driving
- Available in the US as 228i and M235i
- All-wheel drive 228i xDrive available from launch
Woodcliff Lake, NJ – September 9, 2014 6:00pm EDT/3:00pm PDT . . . Few new cars have been more anticipated than the BMW 2 Series Coupe when it arrived in early 2014. Hot on the heels of the widely acclaimed BMW 228i and M235i Coupe, BMW announces the new BMW 2 Series Convertible. Available in the US as the 228i and M235i, the 2 Series Convertible blends the style and dynamic driving character for which the 2 Series Coupe is already renowned with the open-air pleasure of a folding soft-top. The BMW 2 Series Convertible will make its world debut at the Paris Motor Show. The 2015 M235i and 228i as well as the 228i xDrive, featuring BMW’s intelligent all-wheel drive system, will arrive in US showrooms in early 2015. The 2015 BMW 2 Series Convertible will be offered at a Manufacturer’s Suggested Retail Price of $38,850 for the 228i, $40,650 for the 228i xDrive, $48,650 for the M235i, including $950 destination and handling.
The BMW 2 Series Convertible follows in the tire tracks of the pioneer and undisputed leader in its class – the BMW 1 Series Convertible. The 1 Series Convertible entered the fray as the first open-top premium model in the sub-compact segment, went on to defend its position as clear market leader against subsequent pretenders to its throne, and achieved sales figures in excess of 130,000 units worldwide. The development team for the new BMW 2 Series Convertible has focused squarely on building on the strengths which proved pivotal to this success. With even more grace, athleticism and sharpness about its design, clear advances in terms of performance as well as efficiency, and improvements in the driving comfort, functionality and innovative equipment features it offers, the BMW 2 Series Convertible takes the qualities displayed by its predecessor to a new level.
The number 2 has a special importance in the model history of BMW and, since the arrival of the BMW 02 range more than 45 years ago, has represented exceptionally sporting driving pleasure in a subcompact car. Introduced in 1966, the 02 series went on to become a byword around the world for sporty, agile handling – and from 1967 these gifts could also be enjoyed with the roof down. Specialist coachbuilder Baur wasted little time in developing a pair of soft-top variants based on the BMW 02 range which were produced until 1975.
Elegance and openness in the established style of BMW Convertibles.
The exterior design of the BMW 2 Series Convertible displays the typical characteristics of an open-top four-seater from the Bavarian brand. The BMW 2 Series Convertible combines a low-slung silhouette and dynamically stretched lines with compact proportions and powerfully contoured surfaces. As with the 2 Series Coupe, its distinctive looks underline its standalone status in the brand’s model line-up and spotlight the dynamic potential, exhilarating open-top driving experience and premium characteristics which customers can expect. All in all, the eye-catching features which distinguish the BMW 2 Series Convertible from its rivals need no second introduction.
Opening the standard electrically-operated soft-top roof highlights the harmonious transition between the exterior and interior. The shoulderline and soft-top compartment create a level surface that wraps around the passenger compartment and evokes the distinctive “boat deck” character of BMW Convertibles. The rollover bars, which remain out of sight unless deployed as required, also contribute to an overall impression dominated by large level surfaces. The design of the interior is headlined by modern functionality, high-quality materials and the driver focus for which BMW is renowned. And exclusive accents in the center console help to give the BMW 2 Series Convertible a refined premium feel in keeping with the car’s character.
Hallmark BMW design language, classical features of a BMW Convertible.
The front end of the BMW 2 Series Convertible, which adopts the brand’s familiar design language, exudes power and presence. As with the BMW 2 Series Coupe, front-end structuring comes courtesy of lines that converge dynamically on the large, slightly forward-slanting BMW kidney grille. The contours of the twin circular headlights narrow at their inner extremes and are replicated by the outlines of the outer air intakes. Air Curtains integrated into the front apron serve to channel the onrushing air precisely behind the front fenders, reducing turbulence in the wheel arches. The headlight units are separated from the BMW kidney grille by narrow strips on either side. An LED accent strip – or, if the Xenon lights are fitted, an LED accent light – cuts across the top of the headlights.
Together, the level shoulderline of the BMW 2 Series Convertible and the car’s telltale BMW proportions – the product of short overhangs, a long hood, long wheelbase and set-back passenger compartment – create an ideal environment in which to enjoy an exhilarating open-top driving experience. The positioning of the seats well back in the body gives the driver and passengers an up-close-and-personal experience of not just the onrushing wind and the sun’s rays but also the transfer of power to the rear wheels.
Its shoulderline rises slightly to the rear and merges into the virtually horizontal trunk lid. And it links up with the prominent swage line running alongside it, through the door handles and into the rear, to create a dynamic wedge shape which captures the forward-surging urgency of the BMW 2 Series Convertible. Additional character lines leading from the doors and side skirts to the rear fenders divert the eye to the powerfully formed surfaces around the rear wheel arches, which duly focus attention on the car’s rear-wheel-drive set-up. The BMW 2 Series Convertible’s body is at its widest around the rear wheels. The rear lights, which extend well into the fenders, display the familiar BMW L-shape and have LED-powered light strips. The third brake light is integrated into the trunk lid and likewise illuminates using LED units.
The interior: driver-focused cockpit, cutting-edge functionality, refined premium ambience.
The arrangement of displays and controls familiar from other BMW models gives the BMW 2 Series Convertible’s cockpit a familiar driver focus. The surface structure of the instrument panel, center console and door trim follows the overlapping principle known as “layering”. The bespoke design of the BMW 2 Series Convertible’s center console creates a refined premium feel on board. The controls for the audio system and climate control are set against high-gloss black surfaces, and the air vents have chrome surrounds. These elements are joined by an exclusively designed display for the climate control system with white readouts on a black background. An array of stowage areas and large storage compartments in the doors, meanwhile, contribute to the modern functionality of the interior.
Sport Line and M Sport provide greater individualization.
As the first open-top M Performance Automobile, the M235i Convertible has all the elements to maximize the performance potential of the 2 Series Convertible. Customers of the 228i Convertible tempted to look beyond standard specifications will be able to order one of two lines in the US each of which offer individualization through the use of tailored design and equipment features. Sport Line adds 18-inch light-alloy wheels in their own exclusive design plus sport suspension (not available with xDrive) special door sill strips, seat upholstery, interior trim strips and car key designs. M Sport also comes with its own unique trims, car key, plus an M Sport aerodynamic body kit developed specially for the BMW 2 Series Convertible.
The surrounds for the outer air intakes, the front of the kidney grille bars, the cross rib in the central air intake and the rear apron all have a high-gloss black finish in the Sport Line. These details join together with a reduction in the number of kidney grille bars from 11 to 8 and exhaust tips in black chrome to highlight the dynamic character of the BMW 2 Series Convertible. Sport seats for the driver and front passenger, a specially styled instrument cluster and a knee pad on the driver’s side of the center console heighten the sense of sporting flair in the interior. M Sport, on the otherhand, also comprises sport suspension tuning, including a 10-millimeter drop in ride height (not available on xDrive). In addition, it features 18-inch M light-alloy wheels in double-spoke design, aerodynamically optimized body elements (including large front air intakes, eye-catching side skirts and a diffuser for the rear apron), as well as a special design for the BMW kidney grille and a exhaust tips in high-gloss chrome. In addition to aluminum door sill strips bearing the M logo, features such as sport seats for the driver and front passenger, Aluminum Hexagon interior trim strips with an accent strip in Estoril Blue, an M leather steering wheel, a special dial design for the instrument cluster, and an M driver’s footrest also combine to bring an aura of sporty driving to the interior of the BMW 2 Series Convertible.
The Track Handling Package, which is available on the 2015 228i Coupe, will also be available for the 228i Convertible. Inspired by the original formula of BMW “S-package” vehicles manufactured in the course of the past three decades, the new Track Handling Package embraces the desires of the most enthusiastic BMW drivers. It includes the Adaptive M Suspension, Michelin Pilot Super Sport tires on unique 18-inch light-alloy wheels, Variable Sport Steering, and M Sport Brakes.
The fabric soft-top opens and closes in 20 seconds, even when on the move; three color variants, optimized acoustics.
The lines of the multi-layered fabric roof emphasize the dynamic looks of the BMW 2 Series Convertible. The soft-top’s classic, pared-down appearance exudes a feeling of lightness and is complemented by optimized acoustics and unrestricted year-round usability. Soundproofing has been improved compared with the car’s predecessor through the introduction of additional insulation for the soft-top skin. This measure cuts interior noise by 5 dB(A) in the front seats and 7 dB(A) in the rear.
When spontaneous open-top driving pleasure is the order of the day, the standard electrically operated soft-top can be opened in 20 seconds at the touch of a button – and it also closes in the same small sliver of time. The opening/closing process can also be initiated while on the move at speeds of up to 30 mph (50 km/h). If the car features the Comfort Access option, the roof can also be opened and closed remotely.
As an alternative to the standard Black, the fabric soft-top can be ordered in two optional colors. For the Anthracite with silver effect top and Brown with silver effect option, the fabric of the cover is interwoven with fine shiny fibers. This gives the material a high-quality, shimmering metallic surface impression, producing attractive reflections under sunlight.
Increased spaciousness, load capacity and variability.
The increased exterior dimensions of the BMW 2 Series Convertible over its predecessor mean occupants in the four seats can enjoy extra spaciousness and freedom of movement. In addition, the access space through to the rear is now 0.4 inches larger, which, when combined with the standard Easy Entry function for the front seats, means that using the rear seats is a significantly more comfortable experience.
The interior and trunk space can now be used in a wider variety of ways. SAE volumes are not yet available, however, by EC measure the trunk capacity has increased by nine percent with the roof closed and seven percent when the top is folded. The width of the opening to the load area between the rear lights has been increased by 1.4 inches. The soft-top compartment can be raised using a lever in the trunk, increasing capacity. A through-load is standard on the BMW 2 Series Convertible. The aperture between the trunk and rear compartment, available for use when the rear seat bench is folded down, has been expanded in width by 5.9 to 17.7 inches and in height by 1.1 to 9.7 inches. As a result, owners can now transport two 46-inch golf bags, for example, or a pair of snowboards.
With large door pockets, a larger glove compartment, two cupholders in the center console and a storage compartment under the armrest, the BMW 2 Series Convertible also offers increased stowage capacity inside the passenger compartment. The lower section of the door trim offers space for drinks bottles up to one liter in size, while the standard storage package includes cargo nets on the backs of the front seats and securing lugs and nets in the trunk.
BMW 228i Convertible: Power for typical driving enjoyment with efficiency.
Aided by BMW TwinPower Turbo technology with twin-scroll turbocharger, High Precision Direct Petrol Injection, VALVETRONIC fully variable valve lift regulation and Double-VANOS variable camshaft timing, the four-cylinder engine of the BMW 228i Convertible generates maximum power of 240hp between 5,000 and 6,500 rpm from a displacement of 2.0 liter. Its peak torque of 255 lb-ft can be harnessed all the way from 1,450 to 4,800 rpm for sporty power and performance. Mated to an 8-speed sport automatic transmission, the 228i Convertible will accelerate from 0-60 mph in 5.7 seconds. The quick-shifting 8-speed sport transmission includes steering wheel shift-paddles which allow the driver to intervene manually when desired, while a Launch Control function provides the best possible traction and dynamics when accelerating from standstill.
This increase in performance also comes with greater efficiency. While EPA numbers are not yet available for the 228i Convertible, for sake of comparison, the 228i Coupe is more than 30 percent more efficient than its 128i Coupe predecessor.
BMW xDrive intelligent all-wheel drive system available from launch
In a first for BMW in this class of premium convertible, the 228i Convertible will be available with xDrive, the company’s intelligent all-wheel drive system right from launch. The 228i xDrive sprints from 0-60 mph in just 5.6 seconds. BMW xDrive is unique in design and construction. In normal conditions, driving torque is always transmitted to the rear wheels, and most of the time to all four wheels. Normal torque split is 70% rear/ 30% front. The portion of torque transmitted to the front wheels is controlled by a multi-disc clutch that can be fully open, fully engaged or at any level of partial engagement in between. The torque split between rear and front wheels is thus steplessly variable. The clutch is directed by an electronic control system in response to actual road and driving conditions. This gives xDrive a dynamic ability that is unparalleled by other all-wheel drive systems.
xDrive does more than just optimize traction; it can also enhance both agility and stability on grippy as well as slippery road surfaces. Using the same type of logic that Dynamic Stability Control employs to recognize and correct for excessive over- or understeer, xDrive adjusts the front/rear torque split to avoid these tendencies. If the system senses oversteer, it closes the multi-disc clutch completely, sending the maximum possible torque to the front wheels. In the case of excess understeer, xDrive opens the clutch completely, sending no driving torque to the front wheels.
Driving Dynamics Control switch fitted as standard; ECO PRO mode with coasting function and Proactive Driving Assistant.
The standard Driving Dynamics Control switch allows drivers to choose between ECO PRO, COMFORT, SPORT and SPORT+ driving modes.
ECO PRO mode supports relaxed, fuel-efficient driving with features such as a coasting function. This function decouples the engine from the rest of the drivetrain when the accelerator is released at speeds between 50 and 160 km/h (approx. 30–100 mph). Vehicles with the Navigation system also include a Proactive Driving Assistant function, which tells the driver when to lift off the throttle ahead of features such as corners, turn-offs, roundabouts and speed limits. Standard-specification BMW EfficientDynamics technology includes Brake Energy Regeneration, on-demand operation of ancillary units, Electric Power Steering, Optimum Gearshift Indicator (manual transmission) and the Auto Start Stop function, which is included with either a manual or an automatic transmission.
Chassis: precise tuning and wide range of optional systems for enhanced sporty performance and comfort.
The driving experience in the BMW 2 Series Convertible is defined by an outstanding balance between sporty performance and comfort, courtesy of highly advanced, precision-tuned chassis technology, which includes a double-pivot front suspension with spring struts and anti-roll bars as well as a five-link rear suspension, an electrically assisted rack-and-pinion steering system and a high-performance braking system. With its low-weight components, the increase in track width and wheelbase compared with the previous model, the rear-wheel-drive set-up, the low center of gravity and the balanced load distribution between the front and rear axles, the BMW 2 Series Convertible chassis is ideally equipped to offer confident agility, precise handling and superior driving comfort.
Standard Dynamic Stability Control (DSC) includes functions such as the Anti-lock Braking System (ABS), Dynamic Traction Control (DTC), Cornering Brake Control (CBC) and Dynamic Brake Control (DBC). These systems are complemented by Brake Assist, Fading Compensation, the Brake Drying function, the Start-Off Assistant and the Limited Slip Differental emulating Active Differential Brake (ADB-Sport) on the rear axle, which is active even in DSC-Off mode.
The BMW 228i Convertible is equipped with standard 17-inch alloy wheels. 18-inch alloy wheels are available as optional equipment, while the accessories range includes 19-inch forged BMW M Performance alloy wheels.
The available Track Handling Package includes a range of chassis systems including variable sport steering, which features a variable-ratio steering rack that becomes more direct as the steering angle increases, for example when parking or making a turn.
Included in this package is the M Sport brake system featuring four-piston fixed calipers at the front, two-piston fixed calipers at the rear and extra-large brake discs. The calipers are painted dark blue and carry the M logo. The M Sport brakes require 18” light alloy wheels with Michelin Pilot Super Sport tires non-run-flat performance tires.
Also included is the Adaptive M suspension with electronically controlled dampers with a 10-millimeter reduction in ride height compare to the standard suspension set-up.
The BMW M235i Convertible: The first open-top M Performance Automobile
Following the BMW M235i Coupe, the M235i Convertible becomes the first open-top M Performance Automobile, offering the characteristic M brand of exhilarating driving enjoyment. Like the coupe, it features a higher-output M Performance TwinPower Turbo inline six, mated to either an 8-speed sport automatic or six-speed manual transmission. Aerodynamically optimized body features and custom chassis components are matched with typical M precision to the engine performance characteristics, ensuring a perfect blend of outstanding agility and precise handle.
The BMW M235i Convertible amps up the passion and adrenaline of dynamic open-top driving to new heights. Like its BMW M235i Coupe stablemate, the open four-seater also has a distinctive and authentic character rooted in the experience of BMW M GmbH as a developer of high-performance sports cars for general everyday use. Drawing on this exclusive know-how, the BMW M235i Convertible provides the perfect balance of engine power, chassis engineering and aerodynamic characteristics to deliver levels of agility, precision and emotional intensity that are unsurpassed in the premium compact segment.
Inline-six engine with M Performance TwinPower Turbo technology.
The M Performance TwinPower Turbo inline-six in the M235i Convertible offers an infectious blend of responsive power, high revving ability and powerful torque that remains constant over a wide engine speed range. Highlights also include its highly efficient design, which gives the BMW M235i Convertible fuel economy figures that are all the more remarkable in the light of its performance.
The M Performance TwinPower Turbo technology comprises a twin-scroll turbocharging system, High Precision Direct Injection featuring centrally positioned multi-hole injectors, VALVETRONIC variable valve lift regulation and Double-VANOS variable camshaft timing. A cooling system, engine management and engine sound tuning, all of which have been exclusively customized to the requirements of the BMW 2 Series M Performance models, complete the picture. Maximum power of 320 hp is generated between 5,800 and 6,000 rpm, from a displacement of 3.0 liters. The maximum torque of 330 lb-ft is available between 1,400 and 4,500 rpm.
With the standard eight-speed Steptronic sport transmission with Launch Control function, the BMW M235i Convertible accelerates from 0-60 mph in 4.8 seconds.
