That started with the X Coupe (seen left) which BMW debuted as a concept years ago For those of us on the left side of the Atlantic Ocean, diesel 1-series derivatives aren't available. Europeans see every possible 1-series engine, from the 113bhp (and even more torqueless) 116i to half of today's comparo, the 301bhp 135i coupe. Yowza. Here are your Numbers from Across The Pond.
