Chevrolet's current top-specification Camaro, the ZL1, was a sensation when it arrived last year with a staggering 580 horsepower and 556 pound-feet of torque. Now Chevrolet is claiming another impressive feat: a quarter-mile elapsed time run of just 11.93 seconds at 186 km/h (116 mph). To many automotive enthusiasts, quarter-mile acceleration figures are a defining characteristic of pony cars like the Camaro and other high performance vehicles. The posted 11.93-second ET run was completed by a stock ZL1 equipped with an automatic transmission and factory-issued Goodyear Eagle F1 Supercar G:2 tires. When equipped with a manual transmission, the ZL1 completed the quarter mile in 11.96 seconds at 188 km/h (117 mph). To put this into perspective, the quarter-mile times turned in by the ZL1 are shorter than several exotic supercars.

In addition, Chevrolet also claims a 0-100 km/h acceleration time of about 3.7 seconds (3.9 seconds from 0-60 mph), a top speed of 296 km/h (184 mph) and the ability to lap Germany's world famous Nurburgring race track in 7:41.27. All of this while using street-legal, factory-issued components.

"The ZL1 is great at everything and we're very proud of that," said Tony Roma, engineering manager for the Camaro ZL1 program. "You can take it to the drag strip and run 11-second quarter-miles all day long. You can also take it to a road course, where it's balanced, handles well, and does exactly what you want – including lapping Virginia International Raceway's Grand Course in under three minutes – and yet the ZL1 is sophisticated enough to use as a daily driver. It's a supercar you can drive every day."

The Oshawa, Ontario-built ZL1 comes equipped with a performance traction management system that integrates several subsystems in order to enhance performance. These subsystems include traction control, electronic stability control, electric power steering response, third-generation magnetic ride control, and launch control for ZL1s fitted with the manual transmission. To withstand repeated, aggressive launches and heavy loads, the ZL1 features a 9.9-inch rear differential that comes mounted in a cast iron centre section. A standard differential cooler can lower the temperature by a claimed 37 degrees Celsius (100 degree Fahrenheit) for improved longevity and performance.

"We know many of our customers will take their ZL1 to the drag strip," said Gordon Rojewski, driveline development engineer. "Some may just go once, to experience the full potential of the 580-horsepower LSA engine. Others may be more serious, going every other weekend with a set of slicks in the trunk. As such, we set out to make sure the ZL1 would perform for them – on the first pass and on the 100th."

In fact, Chevrolet tested the ZL1 to well over one hundred passes; the high-performance pony car was subjected to 1,000 test cycles before its driveline was approved.
