Infiniti M Hybrid 2012

We expected the Infiniti M Hybrid to save fuel. What we didn't expect was how effectively the electric motor would spice up the driving experience. The Infiniti's 67-hp electric motor complements the 3.5-liter V6 with nearly 200 lb-ft of instantaneous electric torque at liftoff. This hybrid zings, bolting to 60 mph in a little over 5 seconds. 

Yet speed is not the sole goal of a luxury car. "Luxury" is loosely defined as something you don't need but want anyway. And the extra performance of the hybrid system has only increased our desire for this sedan. The gas—electric powertrain is nearly transparent in its operation. At speeds of up to 62 mph it can silently draw on the lithium-ion battery pack and electrically glide for more than a mile. The brakes—which have the tough task of integrating the standard hydraulic system with energy regeneration—feel, well, normal. Plus, the system delivers 29 combined EPA mpg, a 28 percent improvement over the nonhybrid M. During one drive, we used the Eco Pedal feature (it coaches efficient driving with gas-pedal feedback) and got over 30. 


We still admire this car for its sweeping exterior, posh and nearly silent interior, engaging driving experience, reasonable price and the range of optional high-tech features (our favorite is the Lane Departure Prevention system, which brakes a single wheel to automatically keep the car in its lane). The hybrid system makes the case for the M even stronger.
