Bmw Z4 M Coupé

The Bmw Z4 M Coupé is powered by the same unit featured on the M3 and the Z4 M Roadster: the renowned 6-cylinder 3.2-litre that delivers a max output of 252 kW/343 hp at 7900 rpm and a max torque of 269 lb-ft.

Thanks to its high-performance heart, the Z4 M Coupé accelerates from 0 to 100 km/h in 5.0 seconds, while the top speed is limited electronically to 250 km/h or 155 mph.

The chassis and suspension share many components with the M3, like the M differential lock on the rear axle: it
has a six-speed manual gearbox and 225/45 ZR18 tyres at the front and 255/40 ZR18 tyres.

According to BMW, the quality of the Z4 M Coupé performances were tested on the Nordschleife, the Northern Circuit of Nürburgring, where the Z4 M Coupé outperformed the lap times of even the BMW M3 and the BMW Z4 M Roadster.

With respect to the Z4 M Roadster, the Coupé can count on a stiffer body – thanks to the closed layout – with a torsional stiffness of 32,000 Nm/°.

From the Official Press Release:

The design

While obviously being closely related to the BMW Z4 M Roadster, this fixed-roof two-seater goes its own way also in its design and styling. The low and sleek curvature of the roof typical of a coupé and the striking look of the car from the side make this new model unmistakable at first sight.

Even at very first sight, the BMW Z4 M Coupé offers a clear impression of the purist diving pleasure this unique car is able to provide. The entire front section of the BMW Z4 M Coupé – like that of the BMW Z4 M Roadster – emanates
a thrilling sense of power and forward-urging dynamism.

This impression is accentuated above all by the powerful-looking front air dam with its distinct x-shaped lines and openings, the large air intake scoops in the engine compartment lid, the deeply embedded radiator kidney grille, and the two striking precision lines running along the car.

Seen from the side, the design of this two-door sports machine with its
sleek roof extending down to the rear in typical coupé style and the “Hofmeister kick” characteristic of all BMW models, looks particularly
dynamic and powerful.

This characteristic appearance is further accentuated by the passenger cell moved far to the rear and the lowered contour of the roof in the middle. Ultimately, therefore, both the lines of the car and its proportions convey the same convincing message: the BMW Z4 M Coupé is low, dynamic, and fast.

The BMW Z4 M Coupé is also unmistakable, dynamic and full of character from behind: The passenger compartment merges dynamically into the
rear end of the car, giving the rear wheel arches a particularly powerful and muscular look. The horizontal diffuser as well as the chrome-plated twin tailpipes positioned far to the outside add a particularly striking touch. The luggage compartment offers up to 300 litres or 10.5 cubic feet capacity,
giving the BMW Z4 M Coupé very generous and easily accessible space
for a sports car.

Performances

BMW’s new two-seater is powered by the same prize-winning 3.2-litre straight-six M engine also featured in the BMW M3 and the BMW Z4 Roadster. The engine’s performance figures are indeed impressive at very first sight: 3,246 cc displacement, 252 kW/343 hp maximum output at an
engine speed of 7,900 rpm, maximum engine speed of 8,000 rpm. And no
less than 80 per cent of the engine’s maximum torque of 365 Newton-
metres or 269 lb-ft is available at the driver’s request from just 2,000 rpm.

Output per litre is 77.8kW or 106 hp, giving the BMW Z4 M Coupé a power-to-weight ratio of just 5.6 kilos or 7.6 lb/kW. Acceleration to 100 km/h comes in 5.0 seconds and top speed is limited electronically to 250 km/h or 155 mph.

The BMW Z4 M Coupé offers a six-speed manual gearbox laid out for optimum performance throughout the engine’s entire gearshift and
speed range. Short gearshift travel, precise action of the shift lever, and close increments between the six gears – these are the typical features of this outstanding transmission.

In its basic concept, the suspension is identical to that of the BMW Z4 M Roadster, but has nevertheless been geared specifically to the particular requirements of the fixed-head model.

Just how perfectly all the car’s components harmonise
with one another is clearly proven by the BMW Z4 M Coupé on the Nordschleife, the Northern Circuit of Nürburgring, where the 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 is identical in many respects to the chassis and suspension of the BMW M3, with a wide range of shared components. One example is the M differential lock on the rear axle, while the highly effective 18-inch compound brake system comes straight from the BMW M3 CSL. BMW’s DSC Dynamic Stability Control, in turn, supplements the suspension with its significant safety reserves whenever
the going gets critical.

Offering a particularly light but dynamic look, the exclusive double-spoke aluminium rims allow the beholder to fully admire the 18-inch disc brakes, thus emphasising the high-performance character of this very special two-seater. The high-performance 225/45 ZR18 tyres at the front and 255/40 ZR18 tyres at the rear offer an ideal match for the exceptional power and dynamism of
the car.

The body

The safe and dynamic driving qualities of the BMW Z4 M Coupé are also attributable to the extremely strong, torsionally and flexurally stiff structure of the body. With torsional stiffness of 32,000 Nm/ o , the body of this new model sets the standard in its segment, offering both driver and passenger passive safety of the very best: Benefiting from perfect interaction of the body and safety systems, the car’s occupants enjoy perfect protection in virtually any kind of accident.

The interior

The interior of the BMW Z4 M Coupé combines a modern ambience in sporting and purist look with a supreme standard of sophisticated style, design and function all coming together in one harmonious concept. The cockpit
is tailored consistently to the driver, with all controls and instruments placed perfectly on or around the steering wheel for supreme ergonomics.

Multi-function buttons featured as standard help the driver concentrate on the essential, operating the telephone or audio system at the touch of a finger, without having to take his hand off the steering wheel.

The M sports seat offers perfect body support and gives the driver reliable feedback at all times. The M leather steering wheel with perfect grip, in turn, features a strong rim profile and thumb contours for secure grip and precise handling at all times. The speedometer and rev counter naturally come with red needles in the typical style of BMW M. Another highlight of the M models is the variable engine speed pre-warning field in the rev counter, the yellow pre-warning and red warning field limiting the engine speed allowed in each case as a function of current engine oil temperature. So with the temperature of the engine oil increasing, the engine is able to rev faster and move up to
a higher speed range. And last but certainly not least, the BMW Z4 M Coupé stands out from the BMW Z4 Coupé 3.0si also in the design of the gearshift lever knob, the door cutout trim strips, the air conditioning and fresh air nozzles finished in galvanic alloy-treated pearl gloss chrome, as well as the door openers and closing handles.

Colours and design variants.

A selection of four leather colours, two choices of soft nappa leather varying
in its degree of finish, as well as three exclusive trim variants ensure
supreme style and individual freedom within the passenger compartment. Three exclusive M paintwork colours and five additional exterior colour
options enable the customer to give his – or her – BMW Z4 M Coupé a very personal touch.

Equipment

The BMW Z4 M Coupé comes with static bi-xenon headlights for optimum high- and low-beam quality ensuring perfect visibility under all conditions.

Two light rings in the headlights, in turn, provide that typical look so characteristic of BMW. Another standard feature is the two-stage Brake Force Display significantly enhancing traffic safety whenever required:
With the driver braking hard or with the ABS anti-lock brakes intervening,
the area covered by the rear lights is enlarged accordingly.

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 a tyre pressure warning system.

Optional: top-end HiFi systems.

As an alternative to the “regular” sound system, two HiFi systems available
as an option ensure truly excellent brilliance and performance at all times.
The high-end Professional system even uses the most advanced Carver technology able to generate enormous sound pressure by combining the volume of the right and left subwoofers.

Navigation systems with DVD memory

The Business navigation system integrated in the instrument panel uses a DVD comprising geographic data for the whole of Europe. A further highlight is that this system also enables the driver to operate the on-board computer, radio and telephone from the same control panel.

The Professional navigation system, in turn, comes with a 16 : 9 colour monitor adjustable or folding in entirely either electrically or by hand.
And the use of innovative film technology on the surface of the screen
makes the display clear and easy to read under all light conditions.
