2020 Chevrolet Corvette C8 Unveiling
265The 2020 Stingray’s heart is Chevy’s next-generation 6.2L Small Block V-8 LT2 engine, the only naturally aspirated V-8 in the segment. It will produce 495 horsepower (369 kW) and 470 lb-ft (637 Nm) of torque when equipped with performance exhaust — the most horsepower and torque for any entry Corvette.
“Though now placed behind the driver, the LT2 gives the same visceral experience we all expect from Corvette,” said Jordan Lee, GM’s global chief engineer of Small Block engines. “The LT2 has been designed to deliver excellent low-end torque and high-end power to give thrilling pedal response at any RPM.”
The powertrain’s low position enables a low center of gravity for optimal handling. Perhaps the biggest update is found in the lubrication and ventilation system. For the first time ever, the base Stingray will use an engine-mounted dry sump oil system and three scavenge pumps for improved track performance.
During serious track driving, oil volume remains high to avoid diminished performance. The new Stingray’s lateral capability is greatly improved, so the LT2’s dry sump lubrication system had to be redesigned to provide exceptional engine performance even at lateral acceleration levels exceeding 1G in all directions.
A lightweight, 3.2mm-thick glass panel on the rear hatch allows owners to show off the engine. This panel features a cantilevered trailing edge to evacuate heat from the LT2 engine compartment.
Other notable engine characteristics include:
Jewel-like setting in the rear compartment, visible through the rear glass hatch.
Every part, including the exhaust system’s wires, tubes, routing fasteners, coolant hoses, exhaust manifold and even the bolts and fasteners, is built with appearance in mind. All engine components were given careful consideration just like the exterior, and even the heat shields are textured.
A brand-new block and vent system. The centerline of the crankshaft sits an inch lower to the ground where it mates to the transaxle for better handling.
Low-profile oil pan that reduces mass.
Oil cooler capacity increased by 25 percent.
Standard edge Red valve covers.
Corvette’s structure is built around its backbone: the center tunnel. This enables a light, stiff structure to serve as the foundation for the suspension system to perform in an optimized manner. By removing unwanted body compliance, Corvette customers will experience the ultimate in ride performance with outstanding lateral grip capabilities. The car has a solid, connected-to-the-road feel with minimal vibrations at high speeds or on long road trips.
“Our mission was to develop a new type of sports car, combining the successful attributes of Corvette with the performance and driving experience of mid-engine supercars,” said Tadge Juechter, Corvette executive chief engineer.
The tunnel-dominant approach offers many advantages, including:
Improved torsional rigidity with a solid, connected feel on both the road and track.
Outstanding ingress/egress for a mid-engine vehicle. Unlike some competitors, there’s no need for oversized rocker panels to bear structural and load weights, making it easier to enter and exit the vehicle.
Excellent stability due to a low center of gravity and outstanding handling.
Preservation of Corvette’s beloved standard removable roof panel, which can easily be stored in the rear trunk.
A front storage compartment that can fit an airline-spec carry-on and a laptop bag.
Availability in both left- and right-hand-drive variants — a first for Corvette.
Smart packaging with improved cabin comfort, including an additional inch of rearward seat travel and almost double the reclining angle.
