BMW already offers more different size and shapes of cars and SUVs than at any time in its history, and the North American debut of the 2008 BMW 1 Series signals another attempt to provide the sporty-minded buyer on a budget a car that he or she will really enjoy driving.

For its U.S. debut, BMW is adding a two-door coupe to the lineup, which will arrive at BMW dealerships in the first quarter of 2008, and a two-door convertible, which is expected to arrive just in time for summer weather. (The BMW 1 Series has been available in Europe and other markets for more than a year in three-door hatchback and five-door hatchback body styles.)

The 1 Series is currently offered with two diesel and three gasoline engines in most markets, but initially the U.S. will get only the full-dress, high-performance coupe, the BMW 135i, which offers more than 300 horsepower. This will be followed later on by a slightly less frenetic BMW 128i with a 230-hp inline-6 engine and nearly all of the same amenities as the 135i will have, for about $5000 less.
