BMW releases 68.9mpg 3 Series Sport model

With its latest update to the 3 Series range BMW has introduced the most economical 3 Series to date – the 74.3mpg 320d ED – which produces less than 100g/km of CO2, warranting free car tax. Buyers after a slightly sportier machine, without sacrificing too much of the ED's economy, however, can now get themselves the 320d ED Sport.
