2014 Mazda6 Gets Diesel Engine For U.S.

Mazda will now be the second automaker to put a diesel engine into a mainstream midsize sedan, after the VW Passat.

The 2014 Mazda6 goes on sale in January 2013 with a gasoline-powered 2.5-liter four-cylinder engine. Sometime in the second half of 2013, the Mazda6 SkyActiv-D will hit dealers. The twin-turbo 2.2-liter four-cylinder diesel engine has no official specs in terms of power or fuel efficiency, but it will be slated above the 2.5-liter. There has been no official confirmation that a V-6 option is coming, either.

Both engines will team to a regenerative braking system Mazda calls i-ELOOP. Unlike systems in many hybrid cars, this one doesn’t require a separate battery or electric motor. The system saves weight, which is crucial for improved gas mileage.

We'll have to wait even longer to find out mileage figures for both engines.
