New 2.0 liter aluminum block engine will be fitted with different turbochargers for output variants up to 245 PS (180 kW / 241 bhp).

BMW will be offering its range of 2.0 liter four-cylinder petrols exclusively in turbocharged configurations, according to a report by Autocar.

The automaker will have varying output levels for its new 2.0 liter petrol turbo that will top-out in a 245 PS (180 kW / 241 bhp) rated variant, as introduced recently in the X1 xDrive28i (torque: 350 Nm / 258 lb-ft).

That 2.0 liter aluminum block will be fitted with different turbocharging systems depending on the output variant. The range-topping 245 PS version gets a twin-scroll turbocharger while lower-powered variants will make due with a conventional turbo.

The 2.0 liter turbo range will handle all model variants with outputs up to the 245 PS level, above which BMW will slate its 3.0 liter inline straight-six engine for higher-powered variants.

The report doesn't state whether the 1.6 liter turbo BMW Group uses for the MINI brand will also be employed in BMW models with lower output levels.

The new set of 2.0 liter turbo variants will debut in the next-generation 3-Series expected in 2012.
