The ZL1 official presence there remains a wild guess, as Chevrolet could use it to benchmark the Z/28 – which is still being tested, and sometimes crashed – or it could test the waters for braking a new record on the circuit.
With a 6.2-litre, supercharged V8, developing 640hp (477 kW) and 640 lb-ft of torque (868 Nm), the new model outshines the outgoing ZL1 by 60hp and 84 lb-ft (114 Nm), but it also features an updated Magnetic Ride suspension, Performance Traction Management, electronic limited-slip differential, Custom Launch Control and Driver Mode Selector. And if somehow that’s not enough to demolish the 7:41.27 lap time, the car comes either with a six-speed manual transmission with active rev-matching, as well as a brand-new 10-speed automatic with paddle shifters.
According to the video description, the red ZL1 is the 10-speed, while the blue variant is equipped with the manual; moreover, both cars are reportedly louder than the Z/28.
