The six-cylinder in-line engine developed exclusively for the new BMW M340i xDrive Sedan and BMW M340i xDrive Touring stands out with its instantaneous power delivery and appetite for revs, combined with the smoothness for which BMW engines are renowned and unrivalled levels of efficiency for its output class. The 3.0-litre power unit features an aluminium crankcase with a closed-deck construction and a likewise alloy cylinder head. Weight-minimised pistons and con rods and a crankshaft made from forged steel increase internal engine efficiency. Frictional losses are reduced through a process known as ‘form honing’ for the cylinder bores in the crankcase and by means of their wire-arc sprayed steel coating.

The new straight-six generates 275 kW/374 hp, an increase of 35 kW/48 hp on the engine powering the previous range-topping models, while peak torque is up by 50 Nm (37 lb-ft) to 500 Nm (369 lb-ft). Its M TwinPower Turbo technology includes a twin-scroll turbocharger with indirect charge air cooling integrated into the intake system, latest-generation High Precision Injection direct petrol injection, VALVETRONIC fully variable valve timing and Double-VANOS variable camshaft timing for the intake and exhaust sides. Integrating the turbocharging system into the cast-steel manifold results in a remarkably compact design and, at the same time, means the exhaust flow only has to travel a short distance, allowing charge pressure to develop rapidly from low revs. The turbine’s responsiveness is further enhanced by a reduction in the mass moment of inertia of some 25 per cent. And a wide-opening, electrically controlled wastegate helps to keep emissions down. The maximum operating pressure of the direct injection system, with its cantilevered injectors, has been increased from 200 to 350 bar. This optimises fuel metering and minimises the engine’s emissions.

The new BMW M340i xDrive Sedan powers from 0 to 100 km/h (62 mph) in 4.4 seconds, the new BMW M340i xDrive Touring in 4.5 seconds. This makes both models half a second quicker than the range-topping variants of the outgoing 3 Series.
