Starting from March 2010, BMW's most compact X model will be available (in most markets) with a new entry-level four-cylinder version and an additional six-cylinder power unit expanding the engine portfolio available in the X1 to a total of three gasoline and three diesel engines.
The new entry-level X1 sDrive18i is powered by BMW's 2.0-liter four-cylinder gasoline unit producing 150HP at 6,400 rpm and a peak torque of 200Nm or 147 lb-ft at 3,600 rpm.
When fitted with the standard six-speed manual gearbox, the rear-wheel drive (that's what the 'sDrive' moniker stands for) crossover accelerates from standstill to 100 km/h (62mph) in 9.7 seconds and reaches a top speed of 202 km/h or 125 mph.
BMW announces a combined fuel economy in the EU test cycle of 8.2 lt/ 100km (equal to 28.7 mpg US and 34.4 mpg UK) with a CO2 rating of 191 g/km for the manual model. The corresponding figures on the automatic transmission model are 8.4 lt /100 km (equal to 28 mpg US and 33.6 mpg UK) and, respectively, 195 g/km of CO2.
Supplementing the top-of-the-range 258HP X1 xDrive28i is the new X1 xDrive25i that comes with a straight-six petrol that delivers an output of 218HP at 6,100 rpm and 277Nm/204 lb-ft at 2,500 rpm.
Featuring BMW's intelligent xDrive all-wheel-drive system and a six-speed automatic transmission as standard, the X1 xDrive25i sprints from 0- 100 km/h (62mph) in 7.9 seconds and has a top speed of 223 km/h or 138 mph.
According to the Bavarian firm, the xDrive25i's combined fuel consumption in the EU test cycle is 9.3 lt/100 km (equal to 25.2 mpg US and 30.4 mpg UK) with a CO2 emission rating of 217 g/km.
In addition to the two new engine variants, for 2010, BMW has extended the availability of its six-speed automatic transmission to the X1 xDrive18d, X1 sDrive18d, and the X1 sDrive20d models while the range of paintworks has been enhanced with five new shades - Space Grey, Cashmere Silver, Tasman, Sparkling Bronze, and Graphite Blue metallic.
We remind you that BMW's baby crossover / SUV model is scheduled to go on sale in the U.S. in 2011.
