The new straight-six petrol variant, meanwhile, can be specified in either all-wheel-drive BMW 840i xDrive Gran Coupe or classical rear-wheel-drive BMW 840i Gran Coupe form. The BMW 840i Gran Coupe’s standard M Sport differential with active locking function at the rear axle adds to the sense of BMW driving pleasure in its most authentic form. The M Sport differential is also part of standard specification on the BMW M850i xDrive Gran Coupe.
The 3.0-litre unit with BMW TwinPower Turbo technology weighs in at around six kilograms less than the engine it replaces and makes its mark with noticeably enhanced elasticity throughout the rev range. These are both key factors in the agile, fleet-footed handling of the BMW 840i Gran Coupe and BMW 840i xDrive Gran Coupe. The new engine places its maximum output of 340 hp at the driver’s disposal between 5,000 and 6,500 r p m, while peak torque has been upped to 500 Nm – available from 1,600 up to 4,500 r p m.
The new power unit responds instantaneously to every movement of the accelerator and power delivery continues unabated up to very high revs. This enables the new BMW 840i Gran Coupe to dart from 0 to 100 km/h (62 mph) in 5.2 seconds. The new BMW 840i xDrive Gran Coupe is even quicker thanks to its all-wheel-drive technology, taking just 4.9 seconds for the same sprint. The new straight-six unit’s superior efficiency translates into combined fuel consumption figures of 7.5 – 7.4 litres per 100 kilometres for the BMW 840i Gran Coupe and 7.8 – 7.7 litres per 100 kilometres for the BMW 840i xDrive Gran Coupe.
The M Sport differential – which comes as standard on the BMW M850i xDrive Gran Coupe and BMW 840i Gran Coupe and can be specified for the other model variants as part of the M Technic Sport Package – gives the car’s handling an even more dynamic edge. The electronically controlled rear differential lock limits equalisation of the rotational speeds at the inside and outside rear wheel when cornering, allowing the driver to power out of bends with remarkably dynamic verve. The locking effect produced by an electric motor and controlled by the DSC (Dynamic Stability Control) system also optimises traction and power transfer on roads where grip levels vary between the right and left rear wheels by preventing a wheel with insufficient grip from spinning and deliberately channelling drive power to the other wheel instead.
