Mazda has confirmed that it will offer a torquey diesel engine on the new Mazda6 next year.

Mazda says that a 2.2-liter Skyactiv diesel engine will arrive in North America next year under the hood of its 2014 Mazda6 sedan.

The sedan made its North American debut earlier today at the Los Angeles Auto Show, although it has previously been shown in European-specification at the Moscow and Paris shows. The North American model is not cosmetically changed from its across-the-pond counterparts.

The two-stage turbocharged 2.2-liter four-cylinder diesel engine developed under the automaker's Skyactiv high-efficiency program is already on the road in Europe under the hood of the Mazda CX-5 crossover. A diesel-powered CX-5 is also expected to arrive in North America.

In the CX-5, the engine is offered with either 147 or 173 horsepower and 280 or 310 lb-ft. of torque, but only the more powerful variant has been confirmed for the Mazda6. A six-speed automatic is anticipated to be the only transmission offered with the Mazda6 diesel. Unlike many larger diesels, the Skyactiv will not require exhaust after-treatment additives like Mercedes-Benz's BluTEC system.

Mazda has long stated its intention to sell a diesel in the U.S. market, but it waited until the LA show to confirm just which model would get the engine first. The only other midsize sedan to offer a diesel engine in this market is the Volkswagen Passat TDI.

More details on the Mazda6 diesel - including fuel economy estimates - are expected soon.
