Introduced last year, the BMW 1-series Cabrio included a diesel version in its lineup. For the 2009 model year, BMW has announced (in Europe, folks) that the 1-series will sport two additional engines: The 123d sports a 4-cylinder, 2-liter unit good for 204hp goes from 0 to 62 mph in 7.5 seconds, uses 5.4 l/100 km (44mpg) and emits 144 g of CO2 per km. As an entry diesel, there's the 118d model. It will include the same 2-liter engine but with a single turbocharger tuned for 143hp. It still manages a 0-62 mph figure in 9.5 seconds, while burning 4.9 l/100 km of diesel fuel (48mpg U. S.), as well as keeping CO2 emissions under 129 g/km. . The car features other improvements such as a new iDrive interface, a better screen, better navigational system and guided tours, not to add Bluetooth compatibility and several other goodies.
