2012 Infiniti M35h

The Bottom Line: $50,000 to $55,000 (estimated)
Fuel Economy: 27 city/32 highway

Nissan abandoned its so-so Altima Hybrid, but the Infiniti division has no less than three of them. The M35's drivetrain is all new, and it's built around a 302-horsepower Atkinson Cycle V6 and 67-horsepower electric motor, with a seven-speed automatic to get it moving. It also offers an advanced lithium-ion battery pack, which is still rare among hybrids. The M35 has limited range in electric-only mode, but it can reach 62 mph on battery power.
