2006 BMW Z4 M Roadster

The BMW Z4 M Roadster is the high-performance ultra-sports version of the Z4 Roadster. Extending BMW's roadster family right at the top, this unique car takes up and continues the brand's tradition in a segment originally created by BMW M in the first place: Back in 1997, the BMW Z3 M Roadster marked the world's first high-performance production roadster, with more than 15,000 units being sold to customers by the year 2002, making the Z3 M Roadster the best seller in its class and the absolute leader in dynamic performance, agility, and sportiness.

Boasting BMW M straight-six power unit, the Z4 M Roadster features a high-performance engine unparalleled in the roadster market: In 2005 this unique engine received the "Engine of the Year Award" acknowledged and highly respected the world over for the fifth time in a row, setting up a record never seen before. Its specifications alone are very impressive: six cylinders, 3,246 cc, 343 bhp at 7,900 rpm, 269 lb-ft at 4,900 rpm, maximum engine speed 8,000 rpm. Two other figures perhaps say even more about the engine's outstanding performance: Output per liter is 106 bhp and the power-to-weight ratio is 4.1 kilos/bhp. On the road this means acceleration to 60 mph in 5.0 seconds, with the same short time of 5.0 seconds being required for intermediate acceleration in fourth gear from 50-75 mph. Top speed is limited electronically to 155 mph.

Clearly recognizable as a Z4 Roadster, the Z4 M Roadster visualizes its superior character of high performance even more convincingly. The functional and technical qualities of the car are reflected directly and authentically by the design of the Z4 M Roadster, numerous details both outside and inside distinguishing it from the "basic" model.
