The BMW M4 Coupe takes over the role played by the thrilling BMW M3 coupe. The "M4" badge is a reference to the model series that provides the basis for the new M model - and, for the first time, the Coupe will be introduced at the same time as the M3 four-door variant. In the interests of maximising dynamic ability and ensuring excellent efficiency, weight savings of around 80 kilograms has been achieved over a comparably equipped predecessor model. This is attributed to the rigorous application of lightweight design measures. These include the increased use of lightweight materials such as carbon-fibre-reinforced plastic (CFRP) and aluminium for a number of chassis and body components. Indeed, the BMW M4 Coupe incorporates a carbon roof just like its larger coupe relative, the BMW M6 coupe.

Looks
Viewed from the front, the BMW M4 coupe stands out most prominently with its powerful contours which lend it a powerfully expressive face. The twin-bar kidney grille features black paintwork and a M4 logo. The powerfully designed front apron incorporates large intakes, which supply cooling air to the high-performance engine and brakes. Among the other hallmark BMW M design features on display is the characteristic power dome on the bonnet, which hints at the potential of the brawny M TwinPower Turbo power unit and creates space for the intercooler. New exterior mirrors - with their suggested twin-stalk mounts - optimise the aerodynamics of the sporty BMW M4 coupe. The hallmark BMW proportions of a long bonnet, long wheelbase and short front overhang are further emphasised by familiar M design elements.
The redesigned M gills are integrated with Air Breathers, which team up with the Air Curtains in the front apron to help optimise the airflow around the wheel arches and therefore improve aerodynamics. The prominently flared wheel arches encase 18-inch BMW M double-spoke wheels that bear the M logo. At the rear end are high-gloss polished slanting twin exhaust tailpipes, which are framed like jewels by the sculptural rear apron with its integrated diffuser. The tailgate of the BMW M4 Coupe features an integrated rear spoiler made from lightweight carbon-fibre-reinforced plastic. As well as performing a functional aerodynamic role, the tailgate also contributes significantly to the BMW M4's standalone design.

Power
Underneath the BMW M4 coupe bonnet is an all-new six-cylinder in-line power unit the M division. The new power unit sees a slight power upgrade over the previous V8 to 321 kW (431 hp), which is delivered between 5,390 and 7,000 rpm. Peak torque has been increased by roughly 40 per cent to 550 Nm, and is maintained over a very wide rev band (1,800-5,390 rpm). The standard sprint from zero to 100 km/h takes 4.1 seconds. Top speed is electronically limited at 250 km/h, or 280 km/h with the optional M Driver's Package. The power plant needs 8.3-litres of fuel per 100km covered.

Transmission
The engine's power is transferred to the road via a standard six-speed manual gearbox with robust double-plate clutch. A seven-speed M Double Clutch Transmission is also available. As well as changing gear automatically, in manual mode the transmission enables ultra-fast gear changes with no interruption in the flow of power. The integrated Launch Control function ensures optimum sprinting performance off the line, producing acceleration figures that would be out of range with the manual gearbox. The Smokey Burnout function allows the driver to indulge in a degree of rear wheel spin while the car is moving at low speeds. Stability Clutch Control opens the clutch when the car is understeering to bring it back into line.

Chassis
The BMW M4 coupe rides on a double-joint spring strut front axle that features aluminium components, which help to reduce the overall weight of the car. Also lighter than the construction in the outgoing BMW M4 is the new five-link rear axle. The rigid connection between the rear axle subframe and the body further improves on the saloon’s directional stability. The electromechanical steering system in the BMW M4 coupe is the critical component in the link between driver and car. The steering offers the driver three settings as standard, which can be selected at the touch of a button. COMFORT, SPORT and SPORT+ modes allow the level of steering assistance to be adapted to suit the situation at hand and the driver's personal tastes.

Interior
The BMW M4 coupe’s exclusive and functional interior matches the dynamic design of the exterior. The driver grips the standard M Sport leather multifunction steering wheel. A command driving position is provided by the standard bucket-style M sports seats. Like the front seats, the distinctively contoured backrests of the rear seats also offer exceptional lateral support. They are made from a lightweight composite material and can be folded in a 60:40 split. This gives the saloon a degree of variability and everyday usability. The optional Head-Up Display comes with additional, M-specific functions such as a gear display, rev counter and Optimum Shift Indicator. The BMW M4 coupe is fitted with the wide variety of driver assistance systems and mobility services introduced with ConnectedDrive. Among the highlights are a new generation of the Navigation system Professional, offering extra capability, sharper graphics and 3D elements for the map display, Driving Assistant Plus, which warns the driver of a looming collision with a pedestrian, the intelligent anti-dazzle LED High Beam Assistant, Active Protection with Attention Assistant and a further developed version of Active Cruise Control with Stop & Go function.

Verdict
The BMW M3 coupe was a legendary machine. It was revered for its monumental handling, epic performance and its thrilling soundtrack. Many BMW purists were saddened by its demise. However, the BMW 4-series offers more luxury, stature and quality compared to the 3-series coupe. Hence, the BMW M4 is far better than its predecessor, an aspect that should appeal to many M3 coupe enthusiasts.
