BMW announced last year that it would be bringing a more efficient 328d diesel model to the U.S., and the EPA has now released fuel economy estimates for this model. The 2014 BMW 328d sedan is rated at 32/45/37 mpg city/highway/combined when equipped with rear-wheel drive, the 2.0-liter turbo diesel four-cylinder, and an eight-speed automatic. The all-wheel-drive BMW 328d sedan and wagon receive slightly lower estimates of 31/43/35 mpg.
The 2014 BMW 328d marks a new approach for the 3 Series diesel after BMW’s previous attempt in the U.S. with the 335d model of the 2006 to 2011 3 Series. Instead of the new 328d’s efficient four-cylinder, the 335d featured a much more powerful six-cylinder turbodiesel but failed to make a big splash in the U.S. due to its nominal fuel economy benefit and high cost.
The new, more efficient four-cylinder diesel puts the 328d at the top of the heap in terms of diesel fuel economy even when compared to less powerful diesel models from Volkswagen like the Jetta, which is rated at 30/42/34 mpg city/highway/combined. The 2014 BMW 328d produces 180 hp and 280 lb-ft of torque, versus the Jetta's 140 hp and 236 lb-ft.
Compared with the gasoline four-cylinder BMW 3 Series models, the 328d is the fuel economy leader as well: the 320i is rated at 23/36 mpg city/highway and the 328i achieves 22/34 mpg.
The 328d is priced in between the 328i and 335i gasoline models, with a 328d sedan starting at $39,525 with destination. The xDrive all-wheel-drive system adds $2000, and the 328d wagon, which is available only with xDrive, starts at $43,875 with destination. The 2014 BMW 328d goes on sale this fall.
