2012 Infiniti M Hybrid compare

The 2012 Infiniti M35h pushes the envelope with its hybrid system and its driver assistance features, making for one of the most economical luxury sedans, without sacrificing power.

The 2012 Tesla Model S sets a new standard for cars of the 21st century by integrating cabin tech equal to anything from the consumer electronics industry and incorporating a long-range, powerful, and efficient electric drivetrain.

The 2013 Lexus GS 350 makes for a convincing high-tech cruiser. With the F Sport package, it has some real performance chops, although it falls short of a BMW M or Mercedes-Benz AMG.

The 2014 Acura RLX makes a game attempt at being a high-tech roller, but suffers from flaws serious enough that they should send Acura back to the drawing board.
