BMW TwinPower Turbo Technology will be offered in all the engines of the BMW X3 model variants starting in the spring of 2012. The latest engine added to the drive train portfolio is the 2-litre, four-cylinder 180 kW/245 hp petrol engine, which makes the BMW X3 xDrive28i more powerful and efficient.
The technology package used in this engine includes a supercharging system that operates according to the Twin Scroll principle, High Precision Injection with direct fuel injection, VALVETRONIC variable valve control and double VANOS variable camshaft control.
This combination ensures spontaneous throttle response and sporty power delivery that continues into the high load range as well as a favorable fuel economy even for a petrol engine of this performance class.
When compared to the previous engine, the new power unit mobilizes 40% higher maximum torque, which has risen to 350 Nm and is offered within a considerably wider engine speed range between 1,250 and 4,800 rpm.
The pulling power and response are improved, enabling the new BMW X3 xDrive28i to accelerate from 0 to 100 km/h in only 6.7 seconds, faster than the predecessor model by 0.2 seconds.
It results to an average fuel consumption of 7.5 litres/100 km in the EU test cycle and a CO2 emission level of 175 grams per kilometer – better than previous figures by around 17 percent. The new power unit is offered as standard in conjunction with the eight-speed automatic transmission.
The optimum transfer of torque to the road and off-road terrain is made possible with the intelligent four-wheel drive system BMW xDrive with electronically controlled and variable power distribution between the front and real wheels.
