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. 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.
