Unprecedented levels of refinement, track capability and drag-strip performance
DETROIT – The 2017 Camaro ZL1 is poised to challenge the most advanced sports coupes in the world in any measure – with unprecedented levels of technology, refinement, track capability and straight-line acceleration.
“The Camaro ZL1 is designed to excel at everything,” said Mark Reuss, executive vice president of Global Product Development. “It’s a 2+2 coupe offering incredible performance – acceleration, handling and braking – with the highest levels of technology and perfect chassis damping, making it suitable for everyday driving. It will compare well to any sports coupe, at any price and in any setting.”
Acceleration for the ZL1 is delivered with a new supercharged 6.2L V-8 engine estimated at 640 hp (477 kW), and either a six-speed manual transmission with active rev matching or an all-new 10-speed automatic. Handling capability starts with the lightweight, stiffer structure of the all-new sixth-Gen Camaro, married with Magnetic Ride suspension and an electronic limited-slip differential. Standard technologies include Driver Mode Selector, dual-mode exhaust and advanced connectivity features.
The Camaro ZL1 goes on sale late this year.
Designed for Performance
Functionality defines the Camaro ZL1’s form, with the exterior shaped during more than 100 hours of wind-tunnel testing and on-track validation to improve aerodynamics and cooling for track use. Accordingly, its exterior elements all play a part in managing airflow over, under and through the ZL1.
“The design supports the Camaro ZL1’s exceptional performance and does so with compelling style,” said John Mack, Camaro exterior design manager. “From every angle, the elements coalesce to give the car a purposeful, super aggressive attitude.”
The lower grille opening, for example, offers greater airflow compared to the Camaro SS, and the upper grille incorporates a new version of the “flow-tie” open bowtie insignia. There’s also a new hood, with a carbon fiber insert and heat extractor that pulls hot air from the engine compartment. Additional changes include a larger front splitter, unique rockers, a wing-style rear spoiler and wider front fenders – all tuned to improve aerodynamics for greater high-speed stability.
Inside, there are standard Recaro front seats, along with a sueded flat-bottom steering wheel and shift knob. Chevrolet’s Performance Data Recorder is available.
Fast with finesse
A cohesive suite of performance technologies tailors ZL1’s performance for street and track. Features include an updated Magnetic Ride suspension, Performance Traction Management, electronic limited-slip differential, Custom Launch Control and Driver Mode Selector. It also has a stronger power-to-weight ratio than its predecessor, weighing 200 pounds less, while offering approximately 60 more horsepower and 80 more pound-feet of torque.
The result is a one-of-a-kind driving experience.
“Driving the Camaro ZL1 is best described as ‘fast with finesse,’” said Reuss. “It is beautifully balanced, with perfect damping and isolation for optimal performance and driver confidence in virtually any situation – from the Pacific Coast Highway to Willow Springs to Pomona.”
Additional chassis features include:
- Unique 20-inch forged aluminum wheels with 285/30ZR20 front and 305/30ZR20 rear tires
- Goodyear Eagle F1 Supercar tires with a compound and construction developed exclusively for the Camaro to offer exceptional grip on the track
- Brembo brakes with six-piston monobloc front calipers – featuring the ZL1 logo – and massive, 15.35-inch (390 mm) two-piece front rotors.
Supercharged performance and new 10-speed automatic
Underhood, the ZL1 features a supercharged LT4 6.2L V-8 Small Block engine, with intake and exhaust systems tailored for Camaro. It is rated at an estimated 640 horsepower (477 kW) and 640 lb-ft of torque (868 Nm).
The LT4 is backed by a standard six-speed manual transmission or all-new, available paddle-shift 10-speed automatic. The 10-speed automatic has 7.39 overall ratio for smaller steps between gears. It enables the LT4 engine to remain at optimal rpm levels during acceleration, particularly when exiting corners, for quicker laps and lightning-quick responses on both up- and down-shifts.
This is the first Chevrolet application of the new quick-shift 10-speed, with unique calibrations and hardware developed exclusively for the ZL1. By the end 2018, GM will introduce the new 10-speed automatic in eight vehicle models.
Finally – and unlike some competitors – there’s no need to purchase an optional package to make the ZL1 track ready. Track capability comes standard, with features including an impressive 11 heat exchangers for optimal powertrain cooling.
UPDATE: Chevrolet today revealed the 2017 Camaro ZL1 convertible. It offers comparable performance to the coupe model, thanks to the Camaro’s modular and rigid body architecture, which was designed at the outset to support a high-performance convertible. As a result, only a few minor structural differences separate the coupe and convertible models, enabling the coupe’s track-honed chassis and driver control systems to carry over unchanged. The Camaro ZL1 convertible goes on sale in early 2017.
CAMARO ZL1 LIGHTNING-FAST TRANSMISSION
New 10-speed auto offers quicker shifts than DCT, sets new performance standards
DETROIT – With faster upshifts than a dual-clutch transmission and a wider overall gear ratio spread to optimize performance and efficiency, the all-new available Hydra-Matic 10-speed automatic transmission sets a new performance standard in the 2017 Camaro ZL1 – and raises the bar for the segment.
The ZL1 is expected to be the first volume production car to offer a 10-speed automatic. It builds on the established legacy of Hydra-Matic eight-speed transmission family offered on other Gen Six Camaro models, to deliver higher thresholds of capability, refinement and efficiency.
“There is simply nothing like the experience offered with the new 10-speed automatic in the Camaro ZL1,” said Aaron Link, ZL1 lead development engineer. “It delivers nearly instantaneous, lightning-fast shifts that alter your perception of what an automatic transmission can offer in a high-performance vehicle – whether you’re on the street, drag strip or road course.”
The greater overall performance and efficiency are due primarily to the 10-speed’s wider 7.39 overall gear ratio spread, which enhances off-the-line performance with an aggressive first gear ratio of 4.70. Smaller steps between the gears also help the engine maintain the optimal speed for maximum power at almost all vehicle speeds, especially when exiting a corner on a track.
“The gear ratios are so tightly spaced that the transmission is in the right gear and the engine is at the best rpm for transitions from corners to straights,” said Link. “And with the power from the ZL1’s supercharged LT4 engine, the force you feel in your seat as you accelerate out of a turn will put a grin on your face every time.”
Chevrolet testing has shown the ZL1 with the available 10-speed has faster shift times than the Porsche PDK dual-clutch transmission. In fact, the 1-2 upshift is 36-percent quicker than the PDK, while the 2-3 and 3-4 upshifts are 27-percent and 26-percent quicker, respectively.
“You touch the paddle and the gear changes with immediacy,” said Link. “The shifts happen so quickly and without delay that it almost feels like an extension of your reflexes. It’s a much more involving experience for the driver that really helps improve confidence and performance on the track.”
Hundreds of hours were spent integrating the 10-speed’s shift performance with the unique power band of the ZL1’s supercharged 6.2L LT4 engine, which is estimated at 640 horsepower and 640 lb-ft of torque.
The 10-speed also has a numerically lower top gear ratio than Camaro’s eight-speed automatics, which allows the engine to run at a lower speed on the highway, enabling even greater efficiency.
Creative packaging
Creative packaging solutions, which had to accommodate another clutch in comparison to the eight-speed, allow the 10-speed to be the approximate size of Camaro’s other eight-speed transmission. It uses four simple gearsets and six clutches: two brake clutches and four rotating clutches. That’s only one more clutch than the eight-speed, despite having two more forward gears.
It is also the latest transmission with an all-new, proprietary electronic control system and performance calibrations. The calibration is unique for the ZL1’s high-performance-oriented driving experience, while additional applications will feature calibrations matched to their respective performance ranges.
Additional highlights:
- A reduction in spin losses, thanks to only two non-applied clutches and other design features, contributes to greater fuel efficiency
- New ultra-low viscosity transmission fluid reduces friction across the full temperature operating range for greater fuel efficiency
- An internal thermal bypass allows the transmission to warm up faster to its optimal operating temperature for additional fuel efficiency
- Advanced torque converter design contributes to packaging efficiency.
The 10-speed will be produced with an all-new manufacturing system at GM’s propulsion manufacturing facility in Romulus, Mich. It’s part of a $323-million investment in the facility, which employs 850 hourly and salaried workers.
