BMW reveals next stage of EfficientDynamics strategy

BMW is taking its EfficientDynamics strategy forward by introducing a new TwinPower turbo four-cylinder engine for the X3 xDrive28i.

The new engine is set to replace the inline six-cylinder engine and will offer significantly improved fuel economy figures – indeed BMW anticipates that the X3 will be the most fuel efficient petrol sport activity vehicle it has ever sold in the USA.

This remarkable upgrade in both power and efficiency is largely due to the use of BMW TwinPower Turbo technology. It uses high precision direct fuel injection, as well as variable camshaft timing and VALVETRONIC variable valve timing with twin-scroll turbocharging. All of these features combine to give the BMW X3 the sort of power you would not expect from an engine that is naturally aspirated.

It delivers maximum power of 240hp at 5,000rpm with maximum torque of 353Nm developed at just 1,250rpm. It also races from 0-60mph in just 6.5seconds and has a top speed of 130mph.

Despite these advancements in power, the engine is actually lighter thanks to the use of an all-aluminium crankcase. Emissions are also kept low thanks to auto start/stop which will be standard on both the X3 xDrive28i and the X3 xDrive35i.

As an added bonus, the driving dynamics control comes with ECO PRO which enhances fuel efficiency by: optimising the drive train, heating, air conditioning and electrical functions; displaying driving tips to conserve fuel; and displaying fuel saved as “bonus” miles added to a vehicle’s driving range.
