Although U.S. sales weren't very high until a 2005 redesign, Infiniti's M-series has proven that it can offer luxury and performance in a fun-to-drive package that rivals German competitors. Infiniti continues this legacy with the 2013 M37x.
An all-wheel drive counterpart to the rear-wheel drive M37, the $50,850 M37x sends most of its 330 horsepower to the rear wheels -- if the system senses a loss of traction, it electronically applies more power to the front wheels. A seven-speed automatic transmission has an optional Infiniti Drive Mode Selector that allows drivers to switch between throttle and shift presets for better performance or economy in a variety of driving conditions.
The engine pulls the M37x's 4,059-pound weight easily, and disc brakes all around stop it just as well. Handling is crisp for a car this size, and can be made even sharper if you opt for the sport-tuned suspension in an All-Wheel Drive Sport Package.
In the past, Japanese luxury sedans had a tendency to be a bit boxy and bland. Not so with the M37x. It has a sleek and slightly aggressive appearance, and the big sedan is one of the sharpest-looking cars in its class. Good looks continue inside, as well, with leather upholstery on the 10-way adjustable power seats, a suede-like headliner and Japanese Ash accents on the dash and center console. A buyer can easily mistake the M37x for something with a higher price tag.
The rear seat has 37.7 inches of headroom and 36.2 inches of legroom, so even the tallest of your friends and family shouldn't have trouble fitting comfortably. There's also 14.9 cubic feet of space in the trunk, plenty for a few large suitcases.
The M37x comes in only one trim level, but there's plenty of standard equipment: leather upholstery, Japanese Ash trim and heated front seats, for instance. Options include: 20-inch wheels, a sport-tuned suspension and a navigation system with a Zagat restaurant database and to-the-minute weather updates displayed on an eight-inch touchscreen.
