The BMW Z4 M CoupÃ© is a sports car for very special moments in life. Uncompromising, purist and exceptionally powerful, this two-seater offers undiluted dynamism both in everyday traffic and on the race track. Its 3.2-litre M straight-six power unit developing maximum outÂ¬put of 252 kW/343 hp ensures driving performance of the highest calibre.
The Geneva Motor Show is certainly the right place to celebrate the world debut of a very special car: This is where the BMW Z4 Coupé is being presented to the public for the first time.
Right from the start the BMW Z4 Coupé Concept Car presented at the 2005 Frankfurt Motor Show was able to arouse powerful emotions, a great feeling of desirability, and great expectations. And now the production model is making all theses wishes come true, the BMW Z4 Coupé being conceived from the start for sports motoring in its purest form – with a weight-optimised bodyshell, a chassis and suspension superior in every situation, and the 195 kW/265 hp straight-six power unit setting the standard worldwide in its class.
Apart from its supreme power also expressed by peak torque of 365 Newton-metres or 269 lb-ft, the BMW Z4 M Coupé stands out in particular by the unique qualities of the chassis and suspension in conveying the enormous power of the engine to the road. Indeed, the high standard of agility and spontaneity expressed by this unique sports car in responding to all commands from the driver characterises the car’s truly unique character.
Despite being closely related to the BMW Z4 M Roadster, this fixed roof two-seater also sets new standards in terms of design, the low-slung coupé roof and the striking side view guaranteeing an exceptional look from every angle. Indeed, the BMW Z4 M Coupé now entering the market is the most dynamic rendition of the concept car presented at the 2005 Frankfurt Motor Show.
The market launch of the new BMW Z4 M Coupé will run parallel to the introduction of the BMW Z4 Coupé 3.0si in June 2006.
Even at very first sight, the BMW Z4 M Coupé clearly reveals the purist driving pleasure it is able to offer. As on the BMW Z4 M Roadster, the front end of the car, through its superior look of power and performance, exudes an outstanding impression further enhanced in particular by the powerfully designed front air dam with its x-shaped lines and openings as well as the large air intake scoops in the engine compartment lid, the deeply embedded radiator kidney grille, and the two striking precision lines.
Seen from the side, this two-door coupé with its low and dynamic roofline sweeping down to the rear as well as the “Hofmeister kick” in the rear side windows so characteristic of all BMWs ensures a particularly dynamic touch.
The passenger cell moved back far to the rear and the roof drawn in in the middle further accentuate this look of superior power and performance.
The passenger compartment sweeps down powerfully into the rear end of the car, giving the rear wheel arches a particularly powerful and muscular look. Two striking highlights are the horizontal diffuser and the chrome-plated twin double tailpipes fitted right at the outside.
Luggage compartment capacity is up to 300 litres or 10.5 cubic feet, giving the BMW Z4 M Coupé lots of space for a sports car very easily and conveniently accessible at all times.
Three exclusive M paintwork colours and five “regular” exterior colours enable the customer to give his – or her – BMW Z4 M Coupé a very personal, individual touch.

Engine & transmission
BMW’s new two-seater is powered by the prize-winning 3.2-litre M straight-six engine also boasted in the BMW M3 and the BMW Z4 M Roadster. The simple facts and figures characterising this unique engine are highly impressive right from the start: engine displacement is 3,246 cc, maximum output 252 kW/343 hp at 7,900 rpm, maximum engine speed 8,000 rpm.
And at just 2,000 rpm the driver already benefits from 80 per cent of the engine’s maximum torque of 365 Newton-metres or 269 lb-ft. Output per litre from this unique six-cylinder is an outstanding 77.6 kW or 105.5 hp, and the car’s power-to-weight ratio is just 5.6 kg/kW or 4.1 kg/hp. Not surprisingly, therefore, acceleration from 0–100 km/h comes in just 5.0 seconds, with the top speed of the car limited electronically to 250 km/h or 155 mph.
The concept of a high-speed engine always works out particularly well whenever the torque developed by the engine is converted into optimum thrust and traction through a short overall transmission ratio. And precisely this point is proven perfectly by the BMW Z4 M Coupé.
The six-speed manual gearbox in this new, dynamic sports car is laid out to ensure optimum performance throughout the entire transmission and engine speed range. The typical features of this transmission are the short gearshift, precise guidance of the shift lever, and close increments between the six gears.

The superior engine technology boasted by the BMW Z4 M Coupé is further enhanced by the equally superior high-performance suspension. Identical in its concept to the suspension on the BMW Z4 M Roadster, the suspension of the Coupé has naturally been specifically adapted to this unique car. And just how well all components within the car harmonise with one another is clearly borne out by the BMW Z4 M Coupé on the Nordschleife, the Northern Circuit of Nürburgring, where the BMW Z4 M Coupé outperforms the lap times of even the BMW M3 and the BMW Z4 M Roadster.
The chassis and suspension of the BMW Z4 M Coupé shares many features and details with the corresponding components on the BMW M3, one example being the variable M differential lock on the rear axle. The highly effective 18-inch compound brake system, in turn, comes straight from the BMW M3 CSL.
DSC Dynamic Stability Control, offering superior safety reserves, supplements the chassis and suspension in all critical situations.
Like the BMW Z4 Coupé, this high-performance model offers a supreme standard of safety in its driving characteristics and occupant protection. The entire bodyshell extremely resistant to torsional and flexural forces sets new standards in terms of stiffness, just one example being its torsional stiffness of 32, 000 Newton-metres/degree.
It almost goes without saying that the driver and front passenger enjoy all-round protection in the event of a collision: Four frontal and side airbags as well as the car’s restraint systems are activated by the ASE Advanced Safety Electronics System individually as required in each case, depending on the type and severity of the impact.

Tires & wheels
Exclusive to this very special car, the double-spoke aluminium rims, through their particularly “light” look and almost free, unobstructed vision to the 18-inch brake discs, underline the high-performance character of this outstanding two-seater.
The tyres measuring 225/45 ZR18 at the front and 255/40 ZR18 at the rear are perfectly matched to the exceptional performance of the car.
The interior of the BMW Z4 M Coupé combines a modern touch of sporting and purist style with sophisticated class and flair.
This is where design and function come together in a complete, harmonious concept. The cockpit is naturally oriented consistently to the driver, with all controls and instruments arranged in perfect ergonomics on or around the steering wheel. Multifunction buttons featured as standard make it even easier for the driver to concentrate on the essential, enabling him – or her – to operate the telephone or audio system with the touch of a finger, without taking even one hand off the steering wheel.
M sports seats ensure perfect body support and reliable feedback to the driver. With its distinct rim profile and thumb contours, in turn, the M leather steering wheel resting perfectly in the driver’s hands ensures a secure grip and precise handling. Both the speedometer and rev counter boast indicator needles in typical BMW M red.
Another special feature of BMW’s M models is the variable engine speed alert system in the rev counter, the yellow pre-warning zone and the red warning zone limiting engine speed as a function of current engine oil temperature. The speed range available to the driver thus increases parallel to the increase in oil temperature.
Through the particular design of the gearshift lever knob, door cut-out strips, as well as the air conditioning and fresh air adjusters, door openers and closing handles all finished in pearl gloss chrome, the BMW Z4 M Coupé stands out distinctly from the BMW Z4 Coupé 3.0si.
Within the interior a choice of no less than four leather colours, two soft nappa leather options, and three exclusive trim variants ensures individual style and character of the highest calibre.
The BMW Z4 M Coupé comes with bi-xenon headlights ensuring optimum illumination of the road ahead through both the low and high beam. Two light rings at the front give the car the position lights so typical of BMW. Another standard feature is the two-stage Brake Force Display enhancing traffic safety to a significantly higher level: When braking hard or with ABS intervening, the area illuminated by the rear lights increases and grows larger in the interest of greater safety.
Further standard features include automatic air conditioning, a CD radio, an on-board computer, sports seats in leather, a multifunction steering wheel, as well as the tyre pressure warning system.
As an alternative to the “basic” sound system, two optional HiFi systems guarantee supreme brilliance in sound and audio qualities of the highest standard. The Professional high-end system even uses Carver technology able to build up an enormously high level of sound pressure by combining the volume of the right-side and left-side sub-woofers.
The Business navigation system integrated in the dashboard of the BMW Z4 M Coupé uses a DVD comprising the geographical data of the whole of Europe and at the same time serving to operate the on-board computer, radio and telephone.
The Professional navigation system, in turn, gives the driver the option to adjust the 16 : 9 colour monitor electrically or by hand, or even to fold it in completely. And at the same time innovative surface film technology makes the display absolutely clear and easy-to-read under all light conditions.
TopSpeed artists tuning recommendation
Our team has put up a tuning proposal for your future BMW Z4 M Coupe. We’d like to see on that car a BMW M5 -like front bumper. While being both sporty and elegant, it reduces lift and provides extra air intake for engine and brakes. We always liked the front grid from the BMW X-Coupe concept and wanted to see it on a production vehicle. We think it will look really good on a Z4. Carbon fiber engine hood and roof reduce weight, lower the center of gravity and, also enhance the sporty appeal of this coupe. Both wheel arches should be widened to accommodate the new 20” wheels shoed with 255/40 ZR 20 tires at front and 285/35 ZR 20 at the rear. The front arches should include air exhaust holes for the front brakes cooling flow. Side skirts should also be aerodynamically enhanced. Don’t forget to place there the “TopSpeed” logo and you’re new M Coupe is good to go.
