For the 2010 model year, the Smart Fortwo diesel (not sold in the U.S.) will boast a brilliant 21% power boost and also about 18% more torque. With all this extra power, though, the 69 mpg fuel consumption stays the same as before, Smart says. Not to mention it will be faster to boot!

The only problem though: "faster" is a relative term--Smart cars are so excruciatingly slow that even though the 54-horsepower diesel Fortwo can manage zero to 60 in 16.8 seconds now, it might as well be a half an hour. Maybe it's a blessing that some of these compact diesels haven't yet made their way stateside?
