The M TwinPower Turbo Technology used in the BMW 1 Series M Coupe consists of two relatively small superchargers which, because of their low inertia moment, are active even at low engine speeds, each providing three cylinders with compressed air. This results in an unusually spontaneous level of responsiveness. The drivetrain provides its maximum torque of 450 newton metres at as little as 1500 rpm. This is available up into the 4500 rpm range and can be increased by another 50 newton metres in full throttle by means of an overboost function. The maximum level of 500 newton metres permits highly dynamic acceleration manoeuvres, and the forward thrust once again available after each gearshift makes for a linear speed increase typical of M vehicles. The engine reaches its maximum output at 5,980 rpm. With this engine-speed-related performance curve, the 6-cylinder power unit embodies the characteristic M properties of a high-performance engine: the BMW 1 Series M Coupe spurts in just 4.9 seconds from standing to 100 km/h, and the urge to accelerate is limited at 250 km/h by means of intervention in the engine control system
The cooling system of the power unit is designed to enable it to do justice both to its outstanding performance potential and to the particularly high demands of constantly drawing on maximum power output. An additional separate radiator and a specific air duct deal with the increased thermal stress which can be generated by driving in a particularly sporty style on the race track.
The engine's outstanding efficiency is mainly due to direct injection which allows for high-precision fuel supply by means of piezo injectors placed centrally between the valves. In addition, Efficient Dynamics measures such as brake energy regeneration and needs-based control of auxiliary units ensure that the average fuel consumption on the EU test cycle is limited to 9.6 litres per 100 kilometres and CO2 emissions to 224 grams per kilometre
Chassis technology: low weight, high rigidity.
The BMW 1 Series M Coupe has a chassis whose elements have run through BMW M GmbH's racing-oriented development process. Numerous key components were originally conceived for the BMW M3 and are now to be found in the compact high-performance coupe in modified form specifically adapted to the new model. In creating the vehicle set-up, a procedure which includes test runs on the Nürburgring Nordschleife, the interaction of the engine, chassis and body was optimised here again so as to create a characteristic, consistent overall set of properties taking into account the low vehicle weight of 1,495 kilograms.
Both the double pivot front axle and the five-link rear axle of the BMW 1 Series M Coupe are made almost entirely of aluminium. Tubular stabilisers, axle links made of forged aluminium and aluminium shock absorbers round off the lightweight construction concept as applied to wheel suspension.
As standard: variable M differential lock, compound brakes, DSC with M Dynamic Mode, Servotronic.
The BMW 1 Series M Coupe is fitted as standard with a variable M differential lock. This generates lock-up torque as required and completely variably up to 100%, thus providing for optimum traction on all road surfaces. The variable M differential lock responds to differences in rotational speeds in the right and left rear wheel, redirecting drive torque within a fraction of a second. So where there are significant differences in friction coefficients between the right and left rear wheel, for example, optimum traction and maximum propulsion power are ensured. The principle of the engine-speed-sensing M differential lock supports the dynamic qualities of rear-wheel drive both on slippery surfaces and when accelerating out of bends.
The M-specific compound high-performance brake system of the BMW 1 Series M Coupe provides impressive stability even under extreme stress, as well as being extremely light. The design principle of the brake system is derived from motor racing and guarantees excellent deceleration figures with significantly reduced heat sensitivity. Their inner-vented and perforated grey cast iron discs with a diameter of 360 millimetres at the front and 350 millimetres at the rear are linked to the aluminium disc chamber on a floating basis by means of cast-in premium steel pins.
In the BMW 1 Series M Coupe, power transmission to the rear wheels also provides the ideal basis for thrilling driving dynamics due to the consistent separation of drivetrain and steering functions. The rack-and-pinion steering is fitted with the hydraulic power steering system Servotronic which regulates its supportive effect in relation to road speed.
The driving stability control system DSC (Dynamic Stability Control) of the BMW 1 Series M Coupe includes such elements as the Antilock Brake System (ABS), an anti-slip control function (ASC), the brake assistant Dynamic Brake Control (DBC), a drive-off assistant, Cornering Brake Control (CBC), an anti-fading function and a dry brake function. In the wet or on slippery surfaces the driving stability system intervenes early on but discreetly so as to prevent oversteering. As an alternative to normal operating status, the driver can activate M Dynamic Mode (MDM) by means of a switch on the instrument panel, thereby raising the intervention threshold of the driving stability control system. This facilitates driving off on snow or loose sand by means of controlled slip. MDM also enables specifically applied, dynamic oversteering.
