The same engine will also be used in the limited-production Alfa Romeo 4C. The unofficial information comes from Car and Driver, which also reported that the engine will be paired with a standard six-speed manual transmission or a seven-speed dual-clutch automatic. The latter would come from Alfa's parts bin, though Mazda isn't reportedly yet sold on this as it remains committed to its own Skyactiv-branded automatic transmissions.
The next-generation Miata isn't likely to use Alfa's engine, however. It should arrive in 2014, while Alfa's Duetto may arrive as much as one year later. The Alfa is expected to have styling based on the 2uettottanta concept (pictured) unveiled at the Geneva Motor Show.
