Bigger may sometimes be better, but rarely is larger also leaner. That, however, is the reality for BMW’s new 3-Series sport sedan. The all-new 6th-generation 3-Series is clearly larger, gaining both length and width, as well as a longer wheelbase beneath its more aggressive big car bodywork.

But as the 3-Series platform approaches what once was considered 5-Series size, BMW has applied their EfficientDynamic engineering strategy to make it almost as fuel saving as it is fun to drive. In the 328i that means downsizing from a 6-cylinder to 4-cylinder engine. But that four is a 2-liter twin-scroll turbo that generates 240 horsepower. That’s superior to last year’s base six. The 335i dons the 300 horsepower single-turbo six from the 5-Series.

The 328i’s turbo-four is linked to a Driving Dynamics Control with new ECO PRO mode. Fuel saving Automatic Start-Stop and Brake Regeneration are new too. While the standard gear change is still manual, we expect highway fuel economy in the higher 30’s with the also new 8-speed automatic.

But even with this new stingier nature, our first drive around Spain’s famous Catalunya race track shows the “3” has lost none of its punch, with the new engine delivering serious acceleration…0 to 60 is well under 6-seconds…and serious sound in any gear.

The 328i hits BMW showrooms in February with a starting price near $36,000.
