Word has it Mazda may be mulling a return to the coupe market with a two-door version of its shapely new Mazda6 . Auto Express cites unnamed sources as saying the car will bow at the Moscow Motor Show next year and will likely feature the 2.2-liter turbodiesel four-cylinder engine found in the sedan. Good for 173 horsepower, that mill can hustle the four-door to 60 mph in under 7.8 seconds. But Mazda may also turn out a quicker MPS trim (read: Mazdaspeed ) when it comes to the coupe, complete with a turbocharged gasoline four cylinder with upwards of 260 hp.According to the report, there's also some indication the MPS version of the coupe will bow with an all-wheel drive system borrowed from the CX-5 crossover . Both products share basic architecture, theoretically making it easier to swap parts between the two. Auto Express says the two door could bow as early as 2014 with the high-performance variant following along shortly thereafter. Stay tuned.
