BMW still hasn't released official fuel economy numbers for its diesel-powered 2014 328d, but now, those mileage ratings have been posted on the EPA's FuelEconomy.gov website. As expected, the 328d is quite an efficient little machine, with the rear-wheel-drive sedan good for 32 miles per gallon in the city and 45 mpg highway. That even bests the 30/42 mpg of the smaller Volkswagen Jetta TDI.
