engines were joined by Ford's Escape
hybrid on the list. The dual turbocharged 3.0L inline 6 cylinder diesel from BMW
and the Volkswagen
2.0L TDI were the first new 50-state legal diesels to be picked by the Ward's editors. Both of those, along with the Escape
hybrid, got more than 30 mpg in real world testing by the magazine.
hybrid system was updated for 2009 with a new 2.5L gasoline engine and updated control software to provide smoother performance and better acceleration. The Jetta
is capable of getting upwards of 40 mpg in normal use and the BMW 335d
scores in the mid- to upper-30 mpg range.
