BMW today announced the industry's first engine to combine direct petrol injection with Valvetronic induction control.

The six-litre engine, unveiled at the Frankfurt Motor Show, develops over 300kW (408bhp) and peak torque of around 600Nm (442 lb-ft). Like BMW's new four cylinder engines developed for the 3-series, the new V12 has four valves per cylinder and fully-variable bi Vanos camshaft control, eliminating the conventional throttle butterfly.

BMW claims that the combination of direct petrol injection and the Valvetronic system allows proven emission control technology with a conventional three-way catalytic converter and lamba 1 fuel/air management. In an apparent reference to Mitsubishi's Gasoline Direct Injection (GDI) technology (now effectively owned by arch-rival DaimlerChrysler), BMW says its new V12 does not require a special Denox catalyst and can therefore be used with all types of available fuel, regardless of sulphur. Just-auto.com understands Mitsubishi had to delay their first European GDI engine's European launch (in the Dutch built Carisma) for some time after the Japanese roll-out due to problems modifying the emission control system to run satisfactorily on the high-sulphur-content unleaded fuel prevalent on the Continent, and in the UK.

The V12 will be installed in 760i (standard wheelbase) and 760iL (long wheelbase) versions of the new 7-series which will be launched in about a year's time, BMW officials said.
