What Changed for 2009:
- New 3.5-liter V-6 engine in the M35/M35x
- New 7-speed automatic transmission in the M35
- New speed-sensing door locks
- New Scratch Shield self-healing paint
- Several standard and optional equipment changes
first introduced the "M" in 1990-the same year Nissan Motor Corp.'s luxury division debuted as an automotive brand. The 6-cylinder M30, a re-badged coupe or convertible Nissan Leopard, was sold for just three years in the U.S. until it was pulled from the lineup. In 2003, Infiniti revived the M
with the introduction of the 8-cylinder M45, itself a re-badged Nissan Gloria. In 2006, Infiniti launched the new "M"
, their first all-new, clean-sheet design built on Nissan
's FM (Front Midship) platform. The M was offered with a choice of 6- or 8-cylinder power and a generous level of standard equipment. In 2008, Infiniti revised the exterior and interior styling
, increased available options, and added an all-wheel-drive (AWD) option to the flagship M45. The automaker has once again made major improvements to the car for 2009. These include a new and heavily revised V-6 engine, upgraded transmission, innovative paint technology, and more standard features.
All 2009 Infiniti M models are offered with a 4-year/60,000-mile basic coverage warranty, 7-year/unlimited mileage corrosion warranty, and 6-year/70,000-mile powertrain coverage. Infiniti Roadside Assistance is standard during the first four years of ownership.Model Lineup
Infiniti offers the 2009 M in four different models: M35 RWD, M35x AWD, M45 RWD and M45x AWD. The M35 RWD is a rear-wheel-drive (RWD), 6-cylinder sedan. The M35x AWD is identical in chassis and engine, but with all-wheel drive. The M45 RWD is a rear-wheel-drive, 8-cylinder sedan. The M45x AWD shares the chassis and engine with the M45, but it is equipped with an AWD powertrain. Put simply, the M is offered with a choice of V-6 or V-8 power, and with rear- or all-wheel drive.
Designed and built in Japan, the 5-passenger sedan offers a mix of luxury and sport more commonly associated with European manufacturers. Standard features include leather seating, dual-zone automatic climate control, and a 160-watt, 6-speaker audio system with XM radio and Bluetooth. New for 2009, all Infiniti M models feature auto speed-sensing door locks and Scratch Shield self-healing paint. The M35x AWD now includes standard high-intensity-discharge (HID) headlamps and adaptive front lighting (this is standard on the other models). The Wood Interior Trim package adds African Rosewood accents to the interior. The Sport package, available on only the RWD models, adds Rear Active Steer, sport-tuned suspension, sport front seats, sport steering wheel, aluminum pedal accents, sport body styling, and 19-inch wheels.
Several technology-based option packages are available. The Technology package adds an upgraded Bose stereo, DVD-based navigation with voice recognition, RearView monitor and a 9.3-gigabyte Music Box hard drive. The Advanced Technology package upgrades the Bose radio to a 5.1-channel Studio Surround system, adds the Lane Departure Prevention (LDP) system, and adds DVD video to the center console.Powertrain
The 2009 Infiniti M is available with one of two engines. The M35/M35x features a 24-valve, 3.5-liter V-6 engine that is new for 2009. Shared with the Infiniti FX35
, the thoroughly revised powerplant is more fuel-efficient than its predecessor, yet it develops increased power. The engine is rated at 303 horsepower and 262 lb.-ft. of torque. In the standard RWD sedan it is mated to a new 7-speed automatic transmission (2009 EPA fuel-economy ratings of 17 mpg city and 25 mpg highway). The M35x AWD sedan receives the new engine, but retains the 5-speed automatic transmission that is a carryover from 2008. The M45/M45x offers a larger, 32-valve, 4.5-liter V-8 engine rated at 325 hp and 336 lb.-ft. of torque (EPA fuel-economy ratings of 16 mpg city and 21 mpg highway). The V-8 engines are all mated to a standard 5-speed electronically controlled automatic transmission with a manual shift mode.
The front suspension of the 2009 Infiniti M is of an independent design featuring double wishbones with a stabilizer bar and coil springs. The independent rear suspension is multi-link, likewise equipped with a stabilizer bar and coil springs. Front and rear brakes are ventilated discs. A 4-channel anti-lock braking system (ABS) is standard. The standard wheels are 18-inch aluminum alloy with all-season radial tires. Larger 19-inch wheels with high-performance tires are optional.Safety
Both driver and front passenger in all 2009 Infiniti M models benefit from advanced air bag technology including dual-stage front air bags, front-seat-mounted side air bags, and front and rear side curtain air bags (protecting all outboard passengers). Front seat belts are equipped with pre-tensioners and load limiters. Rear seats are fitted with the LATCH (Lower Anchors and Tethers for CHildren) system. Standard active safety systems on the 2009 Infiniti M models include ABS, Vehicle Dynamic Control (VDC) with traction control (TCS), and a direct-reading tire-pressure-monitoring system.
The 2006-07 Infiniti M35/M45 was crash tested by the Insurance Institute for Highway Safety (IIHS
). The frontal offset and side-impact crash ratings were both "Good"-the highest rating the Institute awards.Technology
The Infiniti M has offered Nissan's full-time ATTESA E-TS all-wheel drive on at least one model since it was launched. The advanced AWD system, originally developed for the exotic Skyline GT-R, is configured with RWD bias under normal conditions to deliver a more natural driving feel, Nissan says. While the vehicle is in motion, a 16-bit microprocessor monitors ABS sensors for wheel slippage, while a G-sensor monitors lateral and longitudinal inputs. If a loss of traction is sensed, the ECU sends power instantly to the wheels with traction-automatically varying the torque as needed. Unlike "reactive" AWD systems that must wait for a significant loss of traction before responding, the ATTESA E-TS system responds nearly immediately to offer a much smoother transition of power, according to Nissan. This advanced AWD system works in conjunction with the TCS and VDC to provide high starting traction, smooth acceleration and vehicle stability, the automaker adds.
