The V8 driving BMW's 6 Series models has been given a meaty power boost for Australia - and in the case of the two-door models, the enhancement will cost buyers $500 less than before.
The upgrade also marks the debut of a V8 option in the four-door 6 Series Gran Coupe, entering above the twin-turbo six-cylinder 640i.
Now available in all three bodystyles, the twin-turbo 4.4 litre V8 has been given an extra 30kW and 50Nm of torque, to make for a solid 330kW and 650Nm.
As a result, the 0-100km/h time of all 6 Series variants is now listed at 4.6 seconds - around a half-second quicker than before.
The improved output is thanks in part to the addition of BMW's Valvetronic variable valve control system. Together with the double Vanos variable camshaft timing, direct injection system and twin turbochargers, power is up and efficiency is increased.
That means fuel consumption remains unchanged, sitting at 8.9 l/100km for the 650i hardtop models and 9.2 l/100km for the 650i Convertible.
The arrival of the 650i variant in the Gran Coupe range also brings features largely in-line with the two-door models, including four-zone auto climate control, Comfort heated and ventilated electric front seats, Professional Navigation pack and 600watt Professional audio system.
There's also adaptive LED headlights, High Beam Assist, colour Head Up Display and Surround View, Adaptive Drive, and Dynamic Driving Control with ECO PRO mode.
