BMW M4 Coupe chased on Nurburgring by Corvette Z06

Here’s a footage of a BMW M4 Coupe driven by some UK journalists on track. It is being chased around by a Corvette Z06 equipped with the largest-displacement small-block ever produced, a new 7.0 L (427 cu in) engine codenamed LS7. The LS7 delivers 505 hp (376 kW) and is the most powerful naturally aspirated engine put into a production car from General Motors. The M3 and M4 are powered by the S55 3.0 liter inline-six TwinPower engine producing 425 horsepower and 406 lb-ft of torque. The power is sent to the rear-wheels via a six-speed or an optional 7-speed M DCT transmission.
