2007 BMW Z4 RoadsterWe’ve been talking so much about concepts that we’ve been neglecting the great cars that have already come out and have been adorning the streets with their high power and sophisticated glory. And what vehicle has more sophistication than the BMW, the Z4 Roadster to be exact.

The Z4 Series underwent its first major evolution for the 2007 model year. Heading its extensive list of updates and improvements are all-new, more powerful engines; 6-speed manual and automatic transmissions across the board; more powerful brakes, standard 17-in. wheels and tires now on both models, and a more advanced Dynamic Stability Control system. Along with all this driving-oriented progress, design and materials refinements inside and out enhance both esthetics and function.

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.2007 BMW Z4 Interior

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.

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.
