Output and Torque Diagrams. The all-new BMW Z4 M Roadster is the
high-performance ultra-sports version of the Z4 Roadster so many
customers have been waiting for - particularly in South Africa.
Extending BMW's roadster family in no uncertain performance terms, 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, a model unfortunately not sold in South Africa, marked
the world's first high-performance production roadster. The Z4 M
Roadster: Awe-Inspiring Performance in Every Respect. Boasting BMW M's
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 highly respected and acknowledged "Engine of the Year
Award" for the fifth time in a row, setting up a record never seen
before. Through its high-speed concept and virtually optimum
transmission ratios, this outstanding power unit generates enormous
thrust and performance across the entire rev range. Its specifications
alone are very impressive: six cylinders, 3,246 cc, 252 kW at 7,900
rpm, 365 Newton-metres at 4,900 rpm and maximum engine speed of 8,000
rpm. Two other figures perhaps say even more about the engine's
outstanding performance: Output per litre is 106 hp (77.9 kW) and the
power-to-weight ratio is 5.9 kilos/kW. On the road this means
acceleration to 100 km/h in 5.0 seconds, with the same short time of
5.0 seconds required for intermediate acceleration in fourth gear from
80-120 km/h. Top speed is limited electronically to 250 km/h. The Joy
of Shifting Gears Six Times Over. The high-speed engine concept is
simply ideal for a sports car when it's offerind in combination with a
short overall transmission ratio, since this allows the conversion of
engine power into optimum thrust on the rear wheels. Thus combining the
M final drive with a six-speed manual gearbox, the engineers at BMW M
are able to fulfil this requirement to the highest standard. Short and
crisp shift travel, supreme running smoothness, and precise guidance of
the shift lever, with sensitive feedback ensuring that the gear is
properly in mesh, are typical fortes of this transmission.
