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.
New BMW X3 features a design that expresses agility, elegance, and ruggedness. When you look at the car up front, you will see its forward-slanting kidney grille and its large headlight assembly, which combine with a striking front apron and hood that boast six contour lines. These contour lines sweep down to converge at the kidney grill, lending a bold presence to the X3.
What’s more, twin round headlights coupled with round fog lamps all form a triangular light pattern, which is characteristic of a BMW SAV design. At the headlight assembly’s upper edge is an accentuating chrome trim, which creates a focused design that is typical of a BMW. The carmaker’s signature "Corona Rings" are illuminated to function as daytime running lights. These Corona Rings are illuminated by white LEDS when they are equipped with optional Xenon headlights.
The new BMW X3’s profile is also characterized by its unique interpretation of the distinct BMW X design features. There’s the powerfully flared wheel arches, as well as the short overhangs, which emphasize the BMW SAV’s robust character. Its dynamic silhouette is also accentuated by 3 characteristic lines. What’s more, the new X3's upper contour line at the door handle level steeply rises within the front wheel arch section, then gently flows to the rear. A couple more subtle lines follow the contour line atop the wheel arches.
Additionally, the car’s rear is characterized by its horizontal lines, which emphasize the new BMW X3's robust character. It also has precise lines and expressive surfaces, creating stunning light and shadow effects. The taillights, too, have a distinct T-shape, characteristic of a BMW X3. Furthermore, LED light bars create BMW’s night-time design signature.
Dimensionally speaking, the new X3 is half an inch taller than its predecessor, 3.36 inches longer, 1.1 inches wider, and features half an inch higher ground clearance. It also rides on a 110.6-inch wheelbase that is 0.6 inches longer.
