The BMW 3 Series
is the German automaker's bread-and-butter vehicle in the U.S., accounting for over half its sales. For the 2009 model year, the sedan
versions receive a host of changes that include exterior and interior styling updates. The biggest change to the lineup is the addition of the 335d Sedan
, powered by a 50-state clean diesel engine. With a 3.0-liter, twin-turbo, in-line six-cylinder diesel mill good for 265 horsepower and a hefty 425 pound-feet of torque, the 335d combines city/highway fuel economy of 23/36 miles per gallon with zero-to-60-mph sprints of about six seconds, according to BMW. The 2009 BMW 335d arrives in dealerships at the end of 2008 with a starting price of about $45,000 -- or about $4,000 more than the 335i Sedan -- but the IRS helps sweeten the deal by offering a $900 kickback.
