What do these sketches show for the future of the Infiniti M? Find out inside.

A new sketch, reportedly from Nissan upmarket automaker Infiniti, suggests that the automaker has two new versions of the Infiniti M ready for introduction.  The sketch will look somewhat familiar to fans of the brand, as it interestingly draws from elements of a different sketch shown at the virtual reveal of the Infiniti M sedan from the 2009 Concours d'Elegance at Pebble Beach.

The sketch points to a new Infiniti M Coupe getting at least a virtual reveal at the 2010 Concours in August.  We previously reported that the automaker had been working on a M-based convertible as well, which would give Infiniti a full M line to better compete with the BMW 6-Series and the Mercedes-Benz E-Class.  An inside source at Infiniti told our friends at Autoblog.com that the two vehicles will "extend Infiniti into an area we haven't been before."

Power to these vehicles could come by way of a 3.7-liter V6 engine producing 330 horsepower (246 kW, 335 PS), or a 420-horsepower (313 kW, 426 PS) 5.6-liter V8.  These models will also join the recently-revealed Infiniti M35 Hybrid.  Shown off at the Geneva Motor Show earlier this year, the hybrid is expected to go on sale in 2011.
