The arrival of a diesel engine in the 2014 Mazda 6 has been delayed once again, meaning that we will not see the oil-burning sedan this spring as was previously announced. The cause of the delay is unclear, as Mazda said in a statement that the engine already meets emissions requirements, but needs further development to better provide “the right balance between fuel economy and Mazda-appropriate driving performance.”
The original announcement of a 2014 Mazda 6 diesel came at the 2012 Los Angeles auto show, when Mazda confirmed that the 6 midsize sedan would be receiving Mazda’s 2.2-liter Skyactiv-D turbodiesel four-cylinder that is already offered in Europe. Then, in September 2013, Mazda pushed back the original arrival date from late 2013 until spring 2014 to accommodate final emissions testing.
The SkyActiv-D engine produces 173 horsepower and 310 lb-ft of torque in European trim and is said to offer 30 percent better fuel economy than the Mazda 6’s 2.5-liter Skyactiv gasoline engine. With the 184-hp gas engine, the 2014 Mazda 6 is rated for as much as 28/40 mpg (city/highway) with the optional i-ELOOP regenerative braking system.
Since the emissions testing and certification is reportedly finished, we’re not sure exactly what kind of development is going on with the Skyactiv-D engine now to warrant a second delay. Mazda is not providing a new arrival date for the 6 diesel at this point, but says that more information about the North American timeline for this program is to come.
