With automakers under pressure to boost fuel efficiency, diesel engines are beginning to look like a good bet.
Diesel fuel offers approximately 10 percent more energy per volume than conventional gasoline. It also provides about 25 percent better fuel efficiency. Yes, dieselís long-chain hydrocarbons are more expensive to extract from a barrel of crude, and diesel engines are more costly to build, but these days, thatís mattering less and less.
As a result, automakers are more frequently looking to diesel engines. Two weeks ago, Chevrolet officially rolled out its compact Cruze Diesel. And earlier this year, Volkswagen showed off a diesel hybrid powertrain.
Weíve collected photos of recent entries in the diesel arena. From Audi and BMW to Chrysler and General Motors, we offer some of the best of past months.

A few weeks ago, Chevrolet rolled out the Cruze Diesel, said to be the first American-made diesel compact since the 1986 Chevette. The Cruze will be big on torque, offering 258 lb-ft at 2,000 rpm, compared to 150 lb-ft for the Cruzeís gasoline-burning version.
