Like the B7, the B3 is likely to be slightly more powerful than the standard 3-Series it's based on, along with a range of upgraded technology, comfort, and luxury features. The current B3 S, not sold in the U.S., offers 395 horsepower from the 335i's turbo in-line six-cylinder engine. We expect the next B3 to offer similar numbers. A special-edition Alpina B3 GT3, also not sold in the U.S., was revealed at last year's Tokyo Motor Show, with a sharper overall performance package and 408 horsepower, showing there's potential for more.
In the spy shots, you can see Alpina-specific wheels, a small rear trunk lid spoiler, and BMW M-style Alpina dual exhausts. The bodywork is also--minimally--tweaked, with a slightly more aggressive front bumper treatment. Expect Alpina-specific details in the cabin as well, including Alpina badging and unique materials options.
The Alpina B3 is expected to make its debut in early 2013 as a 2013 model, though whether it will come to the U.S. is still unknown.
