(Source BMW ) New 2006 BMW Z4 M Roadster is the
high-performance ultra-sports version of the Z4 Roadster so many
customers have been waiting for since the Z4 was introduced in 2003.
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
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.

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 "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. Through
its high-speed concept and virtually optimum transmission ratios,
this outstanding power unit generates enormous thrust and
performance in all speed ranges. 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.
The Joy of Shifting Gears Six Times Over
The high-speed engine concept is simply ideal for a sports car in
combination with a short overall transmission ratio, since this
allows the conversion of engine power into optimum thrust on the
rear wheels. And combining the M final drive with a six-speed manual
gearbox, the engineers at BMW M are able to fulfill 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.
Variable M Differential Lock for Supreme Power in Bends
The Z4 M Roadster comes with the speed-sensitive variable M
differential lock already well-known and greatly admired on the M3.
This special feature gives the car both superior driving stability
and optimum traction especially when accelerating out of a bend.
Allowing a very sporting style of motoring, especially on roads with
a higher frictional coefficient, the M differential lock enables the
experienced driver to enhance the positive features of rear-wheel
drive to an even higher standard. Under challenging conditions such
as a different frictional coefficient on each side of the car
typical of winter weather and road surfaces, the system gives the Z4
M Roadster supreme traction and stability.
Z4 M Roadster: High Performance at Very First Sight
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
The most conspicuous highlights are the front air dam with its
X-shaped combination of lines and openings, the large air intake
scoops, as well as the low-slung kidney grille and the two striking
precision lines on the engine compartment lid. A feature exclusive
to the Z4 M Roadster is the double-spoke design of the 18-inch
aluminum rims. And last but certainly not least, the rear end also
comes in that typical M style, with four striking tailpipes and a
