The new BMW X3 has occupied the top slot among the competition by virtue of its compelling driving pleasure, convincing versatility and commanding presence anchored in high-calibre design and no-compromise premium quality. Now this successful Sports Activity Vehicle (SAV) is about to extend its lead even further on the efficiency front. Autumn 2011 will see additions to the model range in the shape of the BMW X3 xDrive20i and the BMW X3 xDrive35d. All-new engines featuring BMW TwinPower Turbo technology endow both models with a further optimised performance to fuel consumption ratio. Added to which, the BMW X3 exudes even more appeal thanks to a fine-tuned range of standard equipment and special options.
From autumn 2011, the new BMW X3 will come with a choice of three petrol engines and three diesel units spanning an output range of 135 kW/184 hp to 230 kW/313 hp. An exceptionally diverse portfolio of power units thus joins forces with the SAV’s outstanding agility – with intelligent BMW xDrive all-wheel drive as standard – and enhanced ride comfort. Thanks to a comprehensive range of BMW EfficientDynamics technology, including the Auto Start-Stop function that can be combined with both the six-speed manual and the eight- speed automatic transmission, the BMW X3 also achieves top ratings in its segment for fuel consumption and CO2 emissions.
The BMW X3 Drive20i will be available as the new entry-level model among the petrol variants. Its newly developed 2.0- litre four-cylinder unit blends a hallmark BMW sporty power curve with exceptionally high efficiency. The new engine’s BMW TwinPower Turbo technology includes a turbocharging system based on the twin-scroll principle, along with High Precision Injection direct petrol injection, Double-Vanos variable camshaft control and VALVETRONIC variable valve control. Here the new powerplant takes its lead from the technology package of the 225 kW/306 hp multi-award-winning six-in-line unit of the BMW X3 xDrive35i.
A new edition of the world’s sportiest six-cylinder diesel engine will deliver a particularly enthralling experience of driving pleasure in the new BMW X3 xDrive35d from autumn 2011. The 3.0-litre six-cylinder in-line unit with BMW TwinPower Turbo technology drums up peak output of 230 kW/313 hp, reached at 4,400 rpm, making the BMW X3 xDrive35d the most powerful variant in the SAV’s model range. With maximum torque of 630 Newton metres on tap from as low as 1,500 to 2,500 rpm, the new diesel engine also ensures impressive pulling power.
The BMW TwinPower Turbo technology of the new all-aluminium unit comprises further advanced two-stage turbocharging (Variable Twin Turbo) and latest-generation common-rail direct injection. At low engine speeds the small turbocharger is deployed. The air it compresses is first fed past the larger turbocharger to the combustion chambers, ensuring lossless development of charge pressure. During heavier throttle application, an electronic controller of the bypass unit engages the larger turbocharger. Extremely spontaneous response is thus ensured by a power curve to match the relevant requirement. The injection system features precision solenoid injectors and maximum pressure of 1,800 bar to guarantee particularly efficient and clean combustion. The BMW X3 xDrive35d comes equipped as standard with the eight-speed automatic transmission including Auto Start-Stop.
