Infiniti M45 dimensions

The 2010 Infiniti M45 is a midsize luxury sport sedan available in two powerful versions. Traditional features found on both the base model Infiniti M45 with rear-wheel drive and the AWD Infiniti M45x include 18-inch alloy wheels, adaptive xenon headlights, a sunroof, keyless ignition and entry, dual-zone automatic conditioning, 10-way performance heated and ventilated front seatings with driver memory options, Bluetooth and a six-speaker stereo system with a CD/MP3 changer, radio and an optional stereo slot.

The same features packages are available for the Infiniti M45 and Infiniti M45x, except that the Sport suite is only available on the rear-drive version of the car. It contains 19-inch alloy wheels, back active steering, sport-tuned suspension, sport body look-and-feel, bolstered front seatings and dashboard aluminum trim that changes the traditional wood accents.

But if you want all of this, the Sport suite has to be bundled with the Technology suite, which adds a hard-drive-based navigator with real-time traffic upgrades, an updated eight-speaker Bose audio system with a Single-cd player that changes the traditional six-disc changer, 9GB of digital audio cargo, Ipod connectivity, a rearview camera and voice-activated controls.

Step up to the Advanced Technology suite and you get all the bells and whistles: a Bose 14-speaker surround-sound system, adaptive cruise control and a lane-departure warning and prevention system. The Infiniti M45's Luxury suite contains a rear-seat entertainment system, performance reclining and heated back seatings, back climate and stereo controls and a performance back sunshade. .
