Short of pickups and full-size utility vans, there aren't a lot of diesel vehicles available in the US. But the vast majority of those oil-burners sold Stateside come from the Germans: Volkswagen, Audi and Mercedes all offer diesel models. Even Porsche can hook you up with a diesel Cayenne. BMW has been limited largely to the X5, but is launching a new diesel offensive from its US dealerships. BMW unveiled the 328d in New York last week, but that's only the first in what it's calling "the next wave of BMW Advanced Diesel models in the US".

The 328d packs a 2.0-liter turbodiesel four with 180 horsepower and 280 lb-ft of torque, delivering a seven-second 0-60 time and economy figures of 32 mpg in the city, 45 on the highway and 37 combined. Buyers will be able to order the 328d in rear-drive sedan, all-wheel xDrive sedan or xDrive wagon, and in a variety of trim levels, arriving in showrooms in the fall. There's no telling which models BMW might offer American buyers in oil-burning form next, but the 5 Series sedan would be a smart bet.
