BMW ENHANCES POWER AND FUEL ECONOMY ON TWIN-TURBO 3.0L DIESEL

Together with the new ATC, BMW is proudly presenting the latest results in the development of particularly powerful and, at the same time, impressively economical straight-six power units.

Indeed, these new engines, whether running on gasoline or diesel fuel, offer a significantly better balance of fuel economy and superior performance than ever before – quite simply, because both engines use special technologies developed by BMW to enhance both efficiency and dynamic performance. Both power units therefore offer the same kind of momentum and superiority in the development of power otherwise provided only by a much larger eight-cylinder, while at the same time they are naturally much lighter and offer substantially better fuel economy and emission management.

BMW’s new TwinPower Turbo gasoline engine developing 225 kW/306 hp for the first time combines turbocharging, direct fuel injection and fully variable valve management in one drive unit. This combination of a twin-scroll turbocharger with High Precision Injection and VALVETRONIC exclusive to BMW gives the new engine fully suited for the world market not only unusually spontaneous and direct behaviour, but also exceptionally low fuel consumption and emission ratings.

This 3.0-litre six-cylinder develops its maximum torque of 400 Newton-metres or 295 lb-ft at an engine speed of just 1,200 rpm and then maintains this superior torque level all the way to 5,000 rpm. In comparison with the straight-six featuring Twin Turbo technology and High Precision Injection already featured in several model series, the engine at the same time offers a further reduction of fuel consumption by up to 9 per cent.

Introducing an additional top version of the six-cylinder diesel already featured in the BMW 730d and the BMW 330d, BMW once again proves the outstanding potential this engine technology has to offer. Again, the new generation of BMW’s straight-six diesel, combining multi-stage turbocharging with common-rail direct fuel injection, offers fascinatingly dynamic power and performance with maximum efficiency. And again in the spirit of BMW EfficientDynamics, numerous innovations on the all-aluminium engine as such, the two turbochargers and the injection system ensure a significant increase in power as well as a further reduction of fuel consumption and emissions. Not only the turbocharger system is even more efficient than before, but also the supply of fuel through piezo-injectors operating at an injection pressure of up to 2,000 bar.

The new 3.0-litre BMW TwinPower Turbo diesel delivers maximum output of 225 kW/306 hp at an engine speed of 4,400 rpm, with peak torque of 600 Newton-metres/442 lb-ft at just 1,500 rpm. These figures alone allow the new engine to take over the leading position from its own predecessor as the most sporting and dynamic six-cylinder diesel in the world, at the same time offering some 4 per cent lower fuel consumption and CO2 emissions.
