Muscle, MPG and Mom: Infiniti's all-new M delivers masterful mix of safety and fuel-sipping technologies

摘要

INFINITI'S NEW '11 M SEDAN PRESENTS a great mix of ridiculous power, astonishing fuel economy and parental-like controls sure to please, and perhaps perplex, buyers. The M's new 5.6L V-8 cranks out a whopping 420 hp and 417 lb.-ft. (565 Nm) of torque. But thanks to direct injection and other fuel-sipping features, we were able to average an astonishing 28.2 mpg (8.3 L/100 km) on one test route through southern California.
