Chevrolet tested the max velocity of the ZL1 (with 10-speed automatic) on the High Speed Oval at Germany’s Automotive Testing Papenburg GmBH proving ground.
Compensating for wind speed, the top speed is the average achieved from running the ZL1 in both directions on the 7.6-mile (12.3km) loop — 325.6kph in one direction and 311kph in the other direction.
“This test caps an impressive list of performance stats for the Camaro ZL1, which was designed to excel at everything,” said Al Oppenheiser, Camaro chief engineer. “It’s the most capable — and fastest —Camaro ever.”

The Papenburg testing was conducted on the ZL1’s production Goodyear Eagle F1 Supercar 3 tires with pressure set at 44 psi, the recommended setting for extended high-speed driving.
The car’s only deviations from stock were mandatory safety equipment and data logging equipment.
Papenburg’s high-speed oval features 2.5-mile (4 km) straights and 1.3-mile (2.15 km) turns with 49.7-degree banking on the top lane.
The steep banking allowed Chevrolet test drivers to run the ZL1 flat out around the track without lifting off the throttle in the turns.
“The ZL1 was developed with high-speed performance in mind, incorporating a balanced aerodynamic package that reduces lift without significantly affecting drag,” said Oppenheiser. “After testing the car in standard settings, which produced the 318kph average, we set the front and rear camber adjustments to 0 degrees and the tire pressures to the maximum allowable sidewall pressure, and saw the ZL1 average over 200 mph (321.9kph).”
Special aero features include a stanchion rear spoiler that offers an advantageous lift/drag ratio compared to a blade-style rear spoiler, and a patent-pending auxiliary transmission oil cooler cover that reduces front-end lift with no drag penalty.
The front-to-rear aero balance was also fine-tuned for high-speed stability.
The 650hp, supercharged LT4 engine powering the ZL1 is matched with a standard six-speed manual transmission with Active Rev Match or an available, all-new 10-speed automatic transmission.
Additional features include:
Magnetic Ride Control
Electronic limited-slip differential (coupe only)
20-inch forged aluminum wheels
Goodyear Eagle F1 Supercar 3 summer-only tires measuring 285/30ZR20 in front and 305/30ZR20 in the rear
Brembo brakes with six-piston Monobloc front calipers and two-piece rotors
The 2017 Camaro ZL1 starts at US$63,435 (RM283,313) for a coupe with the manual transmission, and US$65,830 (RM294,009) for a coupe with the 10-speed automatic.
