2012 Infiniti M Hybrid
Price: $54,595
On sale: March 2011
Why it’s interesting: Gets 32 miles per gallon on the highway for short intervals, running only on its electric engine, yet offers taut handling and 0–to-60 acceleration approaching 5 seconds. It's quicker, cheaper, and more fuel-efficient than its closest competitor, the 2011 Lexus GS 450h.
