BMW's new Z4 M Roadster

The Z4 Roadster 3.0si delivers 195 kW at 6,600 rpm, with 315 Nm of torque available between 2,500 rpm and 4,000 rpm. The engine meets both EU4 and ULEV II emissions standards and accelerates the car to 100 km/h in 5.7 seconds, covering the 80 km/h to 120 km/h run in 5.5 seconds in fourth gear. Top speed is electronically limited to 250 km/h, while fuel consumption in the combined EU cycle is just 8.6-litres/100 km.

The Z4 Roadster 2.5si develops a maximum output of 160 kW and 250 Nm of torque between 2,900 – 4,250 rpm. It will shoot the Z4 Roadster 2.5si to 100 km/h in 6.5 seconds. The muscular engine powers the car from 80 km/h to 120 km/h in just 6.5 seconds in fourth gear. Top speed is 240 km/h and fuel consumption is just 8.4-litres/100 km, while meeting both the EU4 and ULEV II emission standards.

A six-speed manual gearbox is standard across all Z4 Roadster models, while the 2.5si and 3.0si models offer the option of the new BMW Sport Automatic gearbox complete with steering-wheel mounted shift paddles.

Reflecting BMW’s consistent philosophy of continual evolution, the latest generation feature-enhanced Dynamic Stability and Control system comes as standard.

This includes Start-Off Assistance, automatic Brake Fading Compensation and Brake Standby function and auto¬matic Dry Braking.

The integrated Dynamic Traction Control (DTC) function allows drivers to hit one button to improve traction on slippery surfaces. DTC also allows greater slip on the rear wheels whenever appropriate.

On the Z4 M Roadster model, a special configuration of the DSC system allows for the additional slip incorporated in the variable M differential lock.

The Z4 Roadster 2.5si and 3.0si feature BMW’s electromechanical EPS Electric Power Steering. This offers an optimum compromise between feedback and kickback, combined with extra assistance when parking, and a strong self-centring action. Road-speed sensitive Servotronic assistance is also part of the package.
