BMW Z4

More than any other sports car in the world, this unique car embodies the typical roadster: The BMW Z4 Roadster thrills the car world through its fascinating, sporting dynamism created by a perfect synthesis of a high-performance power unit, the outstanding chassis and suspension, and innovative features all round. And not least it is the wonderful design of the BMW Z4 Roadster which makes this car so unique, desirable and a genuine must-have. And now, four years after its world debut, the BMW Z4 Roadster is making a new, brilliant appearance with new engines.

New Six-Cylinder Power Unit for the Z4 Roadster

While the six- and four-cylinder power units featured in the BMW Z4 Roadster naturally cannot match the output and performance of the M engine, they are everything but under-powered. Indeed, the new 3.0-liter straight-six in the BMW Z4 Roadster 3.0si is currently the most innovative engine in its class, setting the standard in motoring refinement and dynamic performance. Further strengths are the engine's high output per liter, a very good power-to-weight ratio, and the lowest specific fuel consumption. Maximum output is 265 bhp at 6,600 rpm, maximum engine speed is 7,000 rpm, and the engine maintains its peak torque of 232 lb-ft maintained consistently from 2,500-4,000 rpm. Complying, last but not least, with both the EU4 and ULEV II standards, this outstanding power unit is also a role model from the perspective of the environment.

The most striking feature from the customer's perspective in comparison with the former engine is the sporting responsiveness of the new power unit in conjunction with thrilling engine sound whenever the driver calls up its power, as well as supreme refinement and motoring culture when cruising or just breezing along.

Superior power and low weight naturally also mean superior performance and efficiency: The Z4 Roadster 3.0si accelerates from 0 to 60 mph in 5.7 seconds, acceleration from 50-75 mph in fourth gear comes in 5.5 seconds.

Like the Z4 M Roadster, the Z4 Roadster 3.0si is limited electronically to a top speed of 250 or 155 mph. Fuel consumption in the combined EU cycle, finally, is just 8.6 liters Premium plus/100 km, equal to 32.8 mpg Imp.

Six Gears on All Models

All new BMW Z4 Roadsters come with a six-speed manual gearbox.

The typical strengths of this transmission are the short and crisp gearshift travel, superior running smoothness and precise guidance of the gearshift lever in the middle, with shift forces remaining smooth and consistent at all times. With the six gears coming close together with only small increments in between, and with the large gap between the lowest and highest gear, the driver is always able to choose the ideal gear ratio quickly and smoothly even when driving fast and dynamically.

Another BMW First: the New Sport Automatic

Automatic transmission in the Z4 Roadster 3.0si and 2.5si comes as a highlight with shift paddles on the steering wheel. In conjunction with the new set-up of the transmission, this outstanding gearshift gives even the aficionade of automatic transmission a dynamic experience of sporting performance in the Z4 Roadster without having to forego the superior comfort of an automatic gearshift.

New Highlights in Design

In their design, both the updated BMW Z4 Roadster and the new Z4 M Roadster consistently continue the characteristic design language of BMW's thoroughbred roadster concept: The BMW Z4 Roadster boasts moderate updates including a modified front section drawn down closer to the road. Other new features are the foglamps and the reflectors so typical of the car.

Benefiting from new tail lights with integrated light conductors as well as more horizontal lines, the modifications at the rear give the car an even wider, lower, and more muscular appearance. Featuring even more sophisticated, top-quality materials and additional colors, the interior is truly exquisite in its looks without in any way foregoing its sporting, purist character.

A Special Roof

All of BMW's new Z4 Roadsters come with an extremely compact folding roof where the front, rigid section moves down on top of the fabric roof like a cover and locks in position flush with the body of the car. The roof is easy to open and close with one hand; the heated rear window is made of scratch-proof mineral glass.

A fully automatic, electrically operated roof is naturally available as an option and comes as standard on the Z4 M Roadster, also opening and closing from outside by remote control.
