Jaws dropped when Chevrolet first announced the 2020 Chevrolet Corvette Stingray Coupe would accelerate 0 to 100 kmph in less than three seconds with the Package. Today, the brand confirms the sportscar with the Z51 Package can reach 100 kmph in 2.9 seconds and cross the quarter mile mark in 11.2 seconds at 121 mph (195 kmph).
Even without the Z51 Package, a base Stingray, can reach 100 kmph in three seconds flat and cross the quarter mile mark in 11.2 seconds at 123 mph (198 kmph). Performance numbers may vary, as different climates, tire conditions and road surfaces may affect results.
The performance of the 2020 Stingray has far exceeded our expectations. Moving more weight over the rear wheels helps us get off the line quicker, but it’s the integration between the powertrain and chassis that really takes the performance to new levels.’
This groundbreaking performance is achieved through a formula of rear weight bias, tire technology, aerodynamics, chassis tuning and of course, the powertrain. The 6.2L LT2 Small Block V-8 engine and eight-speed dual-clutch transmission are in many ways the stars of the show.
Chevy’s Small Block Hits the Gym
The LT2 is the only naturally aspirated V-8 in the segment and is SAE-certified at 495 horespower and 637 Nm of torque when equipped with performance exhaust, making it the most-powerful entry Corvette ever.
Jordan Lee, GM’s global Chief Engineer of Small Block engines, stated:
The LT2 is one of our best efforts yet in Corvette’s history of naturally aspirated high performance Small Block V-8 engines. This engine is incredibly powerful and responsive. Power is readily available when the driver needs it.’
Bespoke DCT Puts the Power Down
Chevy’s first eight-speed dual-clutch transmission was designed to do two things – put the LT2’s power down and put a smile on every driver’s face. The bespoke, transaxle transmission was developed with Tremec to provide uninterrupted torque delivery whether setting a new lap record or heading out on a roadtrip.
Terri Schulke, GM Global Chief Engineer of Transmissions, announced:
The goal from the beginning was to design a transmission worthy of an exotic supercar that is fun to drive everyday. We achieved that goal by combining the best attributes of the LT2 and the DCT, and I think the impressive performance numbers speak for themselves.’
Engineering decided to use a dual-clutch design because it better supports the Stingray’s new mid-engine architecture and desired performance. The DCT aids vehicle performance with a very low center of gravity, enables desired weight distribution and offers maximum traction under acceleration.
The heart of the DCT uses dual concentric wet clutches that are opened by springs and closed by hydraulic pressure. The two clutches work in tandem for uninterrupted torque delivery as they toggle between gears.
The final drive and differential are integrated for the first time and make for an incredibly efficient package. A mechanical slip differential is standard on all 2020 Stingrays.
Software Plays Key Role
Beyond hardware, the transmission software controls are really where customers will find the most tangible benefits. Most of these will feel familiar when toggling through varying driver modes:
- Tour: Moves to the background to provide quiet, smooth shifts for optimal ride comfort.
- Sport: Gives drivers altered up and downshifts for more spirited driving.
- Track: Maximises vehicle performance with aggressive gear selection expected to keep the engine in a peak performance window.
A proprietary algorithm will influence gear selection if the car senses spirited driving. The level of aggressiveness will change with modes, but when sensed, the DCT can downshift early on hard braking, hold gears when lifting off the throttle and alter shifts points with lateral acceleration.
To achieve peak acceleration numbers on the Stingray, drivers must initiate a performance launch. Once prepared, the driver can then fully depress the brake and accelerator pedal together, and then release the brake pedal once 3,500 RPM are reached.
Extensive work went into ensuring the DCT felt like the best of both worlds: the spirited, direct connected feeling of a manual and the premium driving comfort of an automatic.
The 2020 Chevrolet Corvette Stingray will be available in the Middle East from mid-2020.
