Powerful straight six-cylinder and V8 engines with BMW TwinPower
Turbo technology of the latest generation help each model variant of the BMW 6 Series Gran Coupe develop its sporting potential. The brand-typical qualities and efficiency of the power units are characterised by outstanding response, supreme power delivery and running smoothness.
The multiple-award-winning six-cylinder petrol engine with a Twin Scroll turbocharger, direct fuel injection and VALVETRONIC featured in the BMW 640i Gran Coupe delivers a maximum power output of 235 kW. The six-cylinder with variable multi-stage supercharging and Common Rail direct fuel injection of the latest generation featured in the BMW 640d Gran Coupe delivers a maximum power output of 230 kW and an average fuel consumption of 5.5 to 5.7 litres/100 km (figures according to the EU test cycle, depending on selected tyre format), an exceptional combination, not only in the luxury class. The model range is complemented by the BMW 650i Gran Coupe, the 330 kW, V8 power plant of which also features variable valve control VALVETRONIC.
All model variants come with an eight-speed Sport automatic transmission and the Driving Experience Control function as standard. Using this feature, it is possible to activate, inter alia, the ECO PRO mode to facilitate a more economical driving style. The Auto Start Stop function, which is also standard on all three model variants, provides an additional increase in efficiency.
The masterful conversion of power output into driving dynamics and outstanding comfort characteristics is the result of the BMW 6 Series Gran Coupe’s sophisticated suspension technology. Electromechanical power steering featured as standard comprises a Servotronic function. Dynamic Damper Control, Integral Active Steering and the Adaptive Drive system with Active Roll Stabilisation are available as options.
Additionally, the intelligent four-wheel drive system BMW xDrive will also become available when the BMW 650i Gran Coupe is launched in the third quarter of 2012. However, BMW xDrive will not be available in South Africa. The electronic control system linked to the DSC (Dynamic Stability Control) feature ensures ideal traction, maximum safety as well as optimal handling and power delivery in all weather and road conditions.
Better performance, greater efficiency: V8 engine with BMW TwinPower Turbo technology including VALVETRONIC.
The top-of-the-range model 650i Gran Coupe features the new generation of the 4.4-litre V8 engine with BMW TwinPower Turbo for the very first time. Its two turbochargers located in the V-shaped space between the cylinder banks and the direct fuel injection system High-Precision Injection are now complemented by VALVETRONIC variable valve control, optimising both efficiency and engine response.
The new technology package results in maximum power output being increased to 330 kW by 5,500 rpm and a maximum torque of 650 Nm available between 2,000 and 4,500 rpm. Likewise, fuel economy and exhaust emissions are positively influenced. The BMW 650i Gran Coupe accelerates from 0 to 100 km/h in just 4.6 seconds. Average fuel consumption is between 8.6 and 8.9 litres/100 km, CO2 levels ranging from 199 to 206 grams per kilometre (provisional figures, fuel consumption and emission levels according to the EU test cycle, depending on selected tyre format).
In conjunction with the intelligent four-wheel drive system xDrive, the power of the V8 engine can be utilised even more intensively for dynamic acceleration. Electronically controlled power distribution between the front and rear wheels also optimises, in addition to traction and vehicle stability, the agility of the BMW 650i xDrive Gran Coupe, which sprints from a standstill to 100 in a mere 4.4 seconds. Average fuel consumption is between 9.2 and 9.4 litres/100 km, with CO2 emission levels ranging from 215 to 219 grams per kilometre (provisional figures, fuel consumption and emission levels according to the EU test cycle, depending on selected tyre format).
Straight six-cylinder with BMW TwinPower Turbo technology: Ideal combination both for petrol and diesel power units alike.
The straight six-cylinder petrol engine in the BMW 640i Gran Coupe features BMW TwinPower Turbo technology also comprising a supercharging system, High-Precision Injection and VALVETRONIC. As opposed to the V8 engine, its turbocharger operates according to the Twin Scroll principle, by which the pulsating gas streams from three cylinders at a time are guided to the turbine wheel in separate spiral-shaped paths. In this way, a power output of 235 kW is mobilised at 5,800 to 6,000 rpm from a 3-litre displacement. The engine delivers a maximum torque of 450 Nm between 1,300 and 4,500 rpm. The BMW 640i Gran Coupe accelerates from 0 to 100 km/h in 5.4 seconds. Average fuel consumption is between 7.7 and 7.9 litres/100 km, with CO2 emission levels of 179 to 183 grams per kilometre (figures according to the EU test cycle, depending on selected tyre format).
The BMW TwinPower Turbo technology package for the straight six-cylinder diesel power unit of the BMW 640d Gran Coupe comprises the latest generation of the two-stage, variable supercharging system and Common Rail direct fuel injection with piezo injectors. The 3-litre all-aluminium engine delivers a maximum power output of 230 kW at 4,400 rpm, already providing maximum torque of 630 Nm between 1,500 and 2,500 rpm.
This is made possible by precisely coordinated interaction between a small, variable turbocharger and a large turbocharger, which both ensure optimised power delivery under all load requirements. The BMW 640d Gran Coupe accelerates from 0 to 100 km/h in 5.4 seconds. Average fuel consumption ranges from 5.5 to 5.7 litres/100 km, with CO2 emission levels of between 146 and 149 grams per kilometre (figures according to the EU test cycle, depending on selected tyre format).
All models are equipped as standard with an eight-speed Sport automatic transmission. Sporty handling is enhanced by rapid gearshift, whilst efficiency is optimised at the same time. Moreover, shift paddles are located on the steering wheel for manual gear selection.
Sophisticated suspension technology for a perfect balance between dynamics and comfort.
The suspension technology of the BMW 6 Series Gran Coupe features a double-track control arm front axle and an integral rear axle, both of which are made predominantly of aluminium. Their construction principle offers the ideal prerequisites for sporty handling combined with a comfortable suspension setting.
Dynamic Damper Control is available as an option. The system’s electronically controlled dampers adaptively adjust to suit both the road condition and style of driving. Driving characteristics are optimised even further by means of the optionally available system Adaptive Drive, which also comprises Active Roll Stabilisation. Electronically controlled stabilisers reduce, among other things, the amount of side tilt when taking bends at higher speeds and in the event of sudden changes in direction.
Electronic power steering comes as standard with a Servotronic function for speed-dependent steering assistance. This system features an electric motor that generates the amount of speed-dependent steering assistance made available.
The BMW 6 Series Gran Coupe is the only vehicle in its class that can be optionally equipped with Integral Active Steering. In addition to regulating the amount of speed-dependent steering assistance and the steering angle of the front wheels, it also controls the steering angle of the rear wheels. The precisely coordinated wheel angles ensure a high level of agility in dynamic driving situations, comfortable and superior vehicle response when changing lanes and in bends, as well as optimised manoeuvrability in narrow bends and city traffic.
Driving Experience Control: The ideal setup at the push of a button.
The Driving Experience Control button on the centre console serves to select the settings “COMFORT”, “SPORT” and “SPORT+“ as well as the ECO PRO mode. The “COMFORT+” mode is also available in conjunction with the options Dynamic Damper Control/Adaptive Drive. The Driving Experience Control function influences accelerator pedal progression, engine response, the characteristic curve of the power steering, the DSC settings, gearshift dynamics of the automatic transmission and, depending on how the vehicle is equipped, also the characteristic curve of the dampers and the Active Roll Stabilisation system.
The ECO PRO mode supports a fuel consumption-optimised driving style at low engine speeds. Targeted power control for electrically operated functions such as air conditioning, heated seats and exterior mirrors ensures exceptionally efficient energy management. Specific displays notify the driver, inter alia, of the additional range gained in kilometres and provide situation-related information pertaining to an efficiency-optimised driving style.
Hence, at the mere push of a button the driver activates a preconfigured and coherent overall setup, which in the BMW 640d Gran Coupe also comprises the sound response of the engine. For this purpose, the engine’s natural sound characteristics are – depending on each driving situation and the selected Driving Experience Control mode – enhanced via a sound module and conveyed into the interior of the car. The system’s digital signal processing allows for a direct exchange of information with the engine management, taking both engine speed as well as torque and vehicle speed into consideration. As a result, the driver is able to obtain a particularly accurate impression of each engine load situation and an even more intense perception of power delivery and the current driving situation.
A further button facilitates separate selection of DSC settings. Using this button, it is possible to activate the traction mode DTC (Dynamic Traction Control), which, for example, provides assistance when starting off and driving on loose sand or in deep snow. In the DSC Off mode, dynamic brake intervention becomes active, this being similar to an electronic locking function for the rear axle differential. In order to optimise traction, targeted and adequate reduction of wheel spin is induced when accelerating in narrow bends, so that drive power and pulling force are maintained via the other wheel on the same axle.
The electromechanical parking brake of the BMW 6 Series Gran Coupe is operated via a button on the centre console. If it is pressed while driving, the braking system is supplied with medium deceleration and ABS-controlled via the DSC hydraulic system. The electromechanical parking brake comprises an Auto Hold function, which enhances comfort particularly in stop-&-go traffic. When the vehicle comes to a halt, it is automatically held at a standstill – even on hills – by constant brake pressure until such time as the driver uses the accelerator pedal again. The Auto Hold function is activated and deactivated via a separate button located on the centre console.
Brake energy regeneration featured as standard ensures by means of intelligent energy management that the generation of electricity for the vehicle’s electrical system is utilised during the overrun and braking phases. Further BMW EfficientDynamics features include on-demand control of ancillary components, electromechanical steering, a detachable air conditioning compressor and reduction of air resistance by means of an active cooling air flap control.
