The all-new 2014 Mazda 6 sedan will provide an optional diesel engine when it starts selling later this year. Mazda displayed its frugal new diesel engine in the international versions of the new 6 sedan but until today, it’s not sure if the engine will be available in the U.S. Earlier this year, Mazda made a pledge that it will later install the SkyActiv-D 2.2 diesel in an American vehicle but no specific car was named.
Automakers don’t frequently offer diesel engines to the market for different reasons, one of which is the Americans’ usual dislike for compression-ignition engines. However, Mazda executives made a public commitment to sell more diesel engines (as well as more upscale models) in the U.S.
By doing this, Mazda would further boost its fuel-economy qualifications. Mazda hasn’t yet confirmed how much the 2.2-liter turbodiesel inline-four in the U.S. produces, the European 6 can deliver 173 hp and 310 lb-ft of torque from this engine. Mazda offers it with a choice between manual and automatic transmissions with six forward speeds. Its fuel economy can easily meet or exceed the 40 mpg mark on the highway.
The diesel model can accelerate from zero to 62mph in as short as 7.8 seconds. A 2.5-liter gasoline inline-four, which delivers 184 hp and 185 lb-ft, is the standard engine in the Mazda 6. The official fuel-economy estimates haven’t been released yet but it’s believed that the engine will be able to return “class leading” highway figures, at 37 mpg or better.
