When the Infiniti M35 first appeared, it was offered in two trim levels: base and Sport. The M35 Sport featured the following standard Infiniti parts: all-wheel-drive, sport suspension, HID headlights, rear-active steering, and climate-controlled seats. Currently, the M35 is still available in two trim levels with the higher-grade version being the M35x AWD. Both offer heated/cooled leather seating, Bluetooth, navigation, a DVD system, reclining rear seats, cruise control, and a Bose stereo. In just a few short years, the Infiniti M35 has made quite an impact on its segment. It was selected as a winner of the Automotive Excellence Award by Popular Mechanics in 2006 and was also named "Best Luxury Sedan" by Motor Week that same year.
The Infiniti M35 debuted in 2005 for the 2006 model year. The original engine configuration was a 3.5L VQ V6 capable of approximately 280 horsepower. As with other Infiniti models, it is built off of the Nissan FM platform. The "FM" stands for "front midship,'' which designates the engine's placement in the engine bay in order for the weight distribution of the vehicle to be more even. Infiniti developed parts for both the M35 and M45 to be in direct competition with notable European competitors, such as the BMW 5 Series and the Mercedes E Class. For the first series of the model, the rear-wheel drive version of the M35 received a 5-speed automatic. When the model was updated for 2008, the rear-wheel drive got the 7-speed automatic while the all-wheel-drive M35x was given the 5-speed.
One of Infiniti's most recognizable models is the M35, a midsize rear-wheel drive luxury sedan that is known for equal parts class and performance. Whereas its platform mate the M45 operates with a V8 engine, the uses a 3.5L V6 which can crank out up to 303 horsepower as well as 262 pounds-per-feet of torque. It runs on a 7-speed automatic transmission (the M35x, the all-wheel-drive version of the model, uses a 5-speed automatic). The M35 also includes such standard safety features as stability control, anti-lock brakes, brake assist, front-seat airbags, side-curtain airbags, and an advanced lane-departure warning system. The Infiniti M35x uses Nissan's ATTESA-ETS all-wheel-drive system, which distributes power to the rear wheels unless slipping is noticed.
On August 23, 2011, the Infiniti M35h set an official for the world's fastest accelerating production full hybrid. The feat took place at the United Kingdom's , where journalist Tim Pollard drove the vehicle down the quarter-mile in 13.896 seconds. The M35h averaged 13.9031 seconds for all runs, reaching speeds over 100 mph. Guinness adjudicators were present to witness the run and certify the record. The official claimed 0-100km/h time for the Infiniti M35h is 5.5 seconds.
The Infiniti M35
Infiniti released a completely redesigned M for the 2006 model year to compete directly in the mid-size sport luxury class, against such class stalwarts as the BMW 5-Series, Lexus GS, and the Mercedes-Benz E-Class. The Infiniti M was released in February 2005, almost exactly at the same time as the new 2006 Lexus GS.
The Infiniti M uses a much more rigid version of the G35/350Z/FX Nissan FM platform and is available with the common VQ-series 280 hp (208 kW) 3.5 L V6 in the M35, or the Q45's 335 hp (249 kW) 4.5 L V8 in the M45. This generation of the Infiniti M is sold in Japan as the Nissan Fuga.
While being 177 mm (7.0 in) shorter on the outside than the last flagship Q45 at 5,069 mm (199.6 in), the M45 boasts more interior space, greater performance, a superior rear multilink suspension and front double wishbone, and friendlier ergonomics due to its 30 mm (1.2 in) longer wheelbase. The Q45 was no longer imported from Japan after the 2006 model year, making the M45 the flagship car of the Infiniti marque.
All-wheel-drive models, called the M35x and M45x, use a sports car-derived system (ATTESA-ETS) to send all power to the rear wheels until slip is detected.
