BMW has finally revealed the three-door version of its latest-generation 1-Series Hatchback, which has been on sale in Europe since last year.

The car is unlikely to be launched in the U.S. though coupe and convertible variants will arrive in the coming year or so, possibly badged as a 2-Series.

Overseas, the new 1-Series three-door hatch comes with several different engine options, including a turbocharged 3.0-liter six-cylinder engine in a range-topping BMW M Performance model dubbed the M135i.

This is the first BMW M Performance model to feature a gasoline engine (the previous were advanced diesels), though we doubt it will be the last. It can be ordered in either three- or five-door bodystyles and comes with a host of performance upgrades including stiffer suspension, a more aerodynamic body and uprated brakes.

Its engine delivers a peak output of 320 horsepower and is reportedly due to appear in M Performance versions of the next-generation 1-Series coupe and convertible models sold in the U.S.

The powertrain options for the rest of the lineup range from an entry-level turbocharged four-cylinder engine with 102 horsepower on tap to a 218 horsepower turbodiesel. All engine variants come with a six-speed manual transmission as standard, with the option of an eight-speed automatic, and some models can even be specified with all-wheel drive.

Inside, customers have the choice of either four- or five-seat configurations. Total storage space is 12.7 cubic-feet with the rear seats up and 42.3 cubic-feet when they're folded flat to the floor.

BMW's new 1-Series three-door hatch range will be making its official world debut at the 2012 Paris Auto Show in September.
