The Chevrolet Corvette Z06 and BMW M4 CS represent two very different approaches to extracting extreme performance from a road car. In a recent track battle, both were subjected to the same circuit, conditions, and driver, with the stopwatch providing the final verdict.
The Corvette Z06 arrived with a 5.5-liter naturally aspirated LT6 flat-plane-crank V8, producing 637 hp in UK specification and 595 Nm of torque. Originally rated at 670 hp, the engine sends its output to the rear wheels through an eight-speed dual-clutch transmission. At 1,560 kg, the mid-engine Corvette also held a substantial weight advantage over the BMW, although its Michelin Pilot Sport 4S tires were less track-focused.
The BMW M4 CS countered with a tuned 3.0-liter twin-turbocharged S58 inline-six producing approximately 750 hp and 900 Nm. Its eight-speed automatic transmission feeds all four wheels through BMW’s M xDrive system. Despite weighing around 1,760 kg, the M4 benefited from Michelin Pilot Sport Cup 2 tires, revised suspension tuning, and substantially greater power.
Behind the wheel, Sam Maher-Loughnan immediately praised the Z06’s chassis balance and mid-engine composure. Its steering and transmission impressed, with the eight-speed DCT receiving particular praise for its responsiveness. However, brake feel emerged as a limitation during the timed lap, preventing the driver from exploiting the chassis as confidently as he wanted.
The BMW initially proved difficult to manage because its enormous power delivery made traction challenging. Once configured correctly in four-wheel-drive mode, however, the M4 CS transformed into a remarkably effective track weapon. Its ability to deploy power on corner exit became a decisive advantage.
The results were striking. The BMW M4 CS completed the circuit in 47.77 seconds, while the Corvette Z06 recorded 48.80 seconds—a 1.03-second advantage for the BMW.
The comparison requires context: the M4 was tuned beyond its standard specification, wore more aggressive Cup 2 tires, and competed with its roof closed, while the Z06 lacked the optional Z07 track package. Nevertheless, the test demonstrated how effectively the BMW’s traction and power could overcome the Corvette’s weight and mid-engine advantages.
Despite the stopwatch result, the Z06 remained the driver’s preferred car, highlighting the distinction between outright lap time and the broader character of a performance machine.
