All-new for the 2006 model year, the M35 is Infiniti's entrant into the mid-size luxury sedan segment and competes with the BMW 5-series and Mercedes-Benz E-class. The car received a modest 'facelift' for 2009 onward.

Based on the same FM platform that underpins the Nissan 350Z and Infiniti FX, the M35 offers plenty of sport to go along with its luxury.

Power for the M35 comes from Nissan's familiar 3.5-liter V6 -- producing 303 horsepower and 262 pound-feet of torque -- mated to a seven-speed automatic transmission that features Downshift Rev Matching.

The M35 is available in two trim levels: M35 and M35x. The base model M35 uses a rear-wheel drive setup, whereas the M35x uses Infiniti's all-wheel drive system.

Standard equipment on either trim level includes dual zone climate control, 18-inch wheels and Bluetooth connectivity.

The rear-wheel drive M35 can be optioned up with a Sport package that includes Infiniti's Rear Active Steer system which turns the rear wheels slightly away from a turn to help the car round a bend, forklift-style. The package also includes uniquely styled 19-inch wheels that are also slightly wider and shod in bigger performance summer tires, a more aggressively tuned suspension, and more supportive front seats. The interior is otherwise changed thanks to a package-specific steering wheel and shifter, with aluminum trim on the console and on the pedals. From the outside, unique front and rear fascias identify the Sport package.

Technophiles might want to opt for the Technology Package, which comprises a Bose-tuned audio system with 8 speakers. The six-disc changer on the standard car is replaced with a single-slot player that integrates a 9.3GB Music Box hard drive that can store MP3 music files from the CD. A full iPod interface is also included. The hard drive also contains navigation data that is displayed via an 8-inch touchscreen display and comes with XM Nav Traffic live updates, though that requires a monthly subscription. The display is also a part of the RearView Monitor system that detects behind the car when reversing. The multi-talented system also features voice recognition to control audio, climate control and the navigation system functions.

The next step up is an Advanced Technology package which should appeal to audiophiles with its 14-speaker Bose surround system capable of digital 5.1-channel decoding and multimedia drive. Other techno goodies in the package involve active cruise control, as well as brake assist and lane departure active safety systems.

A ceiling-mounted DVD multimedia system for rear-seat passengers is another major option, and a Premium package combines all three. Detail additions such as a rear spoiler, wood interior trim, and polished wheels round out the options list on Infiniti's luxury flagship sedan.
