Last year, Infiniti released the M56x, its top sedan loaded with a big displacement V-8. That car offered the power one would expect from a luxury sedan, but the engine was caveman technology. This year, Infiniti shows it can do high-tech motive power equal to the level of tech in its cabins. The M35h hybrid couples Infiniti's tried and true V-6 with a next-generation hybrid power system using lithium ion batteries.

The M35h drives exceptionally well, running in EV mode over a wide range of speeds. The hybrid system boosts power substantially over that of the gas engine alone. Although fuel economy doesn't reach the highs of a Toyota Prius, it is exceptional for a luxury sedan. Add to that Infiniti's innovative driver assistance features, and the car is one high-tech roller.
