Special features for 2009

Part sport sedan and part posh luxury car, the 2009 Infiniti M35 and M45 stand out from the market due to their available onboard technology features, including a sophisticated rear-wheel steering system and a lane-departure system that actually nudges the vehicle back into its lane. Both M models also stand out for having a quiet interior, a well-controlled ride, and strong, smooth powertrains.



Basically unchanged for 2009, the Infiniti M45 midsize luxury sedan is equipped with a powerful, 4.5L V8 engine that provides up to 325 hp and 336 lb-ft of torque with rear-wheel drive, although all-wheel drive is also available. The five-speed automatic transmission has manual shift control and a sporty downshift rev-matching feature. As for fuel economy, the AWD trim gets 14 mpg city/20 mpg hwy, while the RWD trim attains 16 mpg city/21 mpg hwy. Designed more for luxury than sport, the M45 Base comes with climate-controlled seats, adaptive xenon headlights and wood/metal trim. The Infiniti M45 Sport trim is the same as the Base trim on the interior, except for wood-only trim, and features 19-inch wheels and tires, firm suspension and active rear-wheel steering. Options include adaptive cruise control, a Bose surround-sound DVD system, heated/reclining rear seats and a voice-activated navigation system. Standard safety features include stability control, antilock disc brakes with brake assist, stability control, front-seat side airbags, full-length side curtain airbags and active front-seat head restraints.
