General Motors Co. says the new diesel version of the Chevrolet Cruze gets 46 miles per gallon on the highway, making it more efficient than some hybrids.

GM announced the U.S. EPA's fuel economy numbers for the diesel Cruze Wednesday.

At 46 mpg, the diesel Cruze matches the highway fuel economy of the Toyota Prius C subcompact. But the regular Prius hybrid still does better, at 48 mpg.

The Cruze beats its closest competitor, the diesel Volkswagen Jetta, which gets 42 mpg on the highway.

The diesel Cruze goes on sale next month in Baltimore, Milwaukee and other markets where diesels are popular. It arrives in the rest of the U.S. and Canada this fall.

It starts at $25,695. That's $7,755 more than the base price on a gas-powered Cruze.
