2006 Infiniti M45 Sport 4 Dr Sedan Trim Overview

The 2006 Infiniti M45 Sport combines powerful performance with more sport-like handling than the base M45. Under the hood of this rear-wheel-drive luxury sedan sits a 32-valve, 4.5-liter DOHC V8, which delivers 335 hp and 340 ft-lbs of torque at 4,000 RPM. It comes paired with a short-throw 5-speed shiftable automatic and achieves 17/23 mpg. The sport sedan gets a firmer double wishbone front and multilink rear suspension, complemented inside by bolstered sport seats with special stitching and standard climate control (they're heated and cooled). The M45 Sport rides on larger 19-inch alloy wheels with all-season tires. Other upgrades with the 2006 M45 Sport include standard xenon lamps housed in adaptive headlights. Rear active steering controls wheel angle to help smooth out handling during turns.

Standard safety features are extensive. Traction and stability control improve handling. The dual front-side airbags have passenger sensors, and side curtain airbags are standard for both rows. The 4-wheel disc and ABS brakes feature brake assist and electronic brakeforce distribution. Also standard are front and rear stabilizer bars. A tire monitor, automatic headlights, foglights, rain-sensing wipers, an auto-dimming rearview mirror, and mirrors with turn signals complete the safety package. Technologically innovative options include a lane-departure warning system, a rearview camera, and intelligent cruise control.

Seating four in leather-wrapped seats, the 2006 M45 Sport provides plenty of legroom (44 inches in the front, 37 in the back), but only 15 cubic feet of trunk space. A rear armrest doubles as a pass-through. Power front seats have driver's memory settings, and power reclining rear seats are optional. Power windows, locks, and heated mirrors, remote start and remote entry (located on the key fob), a sunroof, a trip computer, and power tilt and telescopic steering are all standard. Cruise control, audio controls, and Bluetooth buttons sit on the leather-wrapped steering wheel. The 6-CD changer has MP3 playback and can be upgraded to a Bose sound system with satellite radio. Alloy accents replace the wood in the Sport trim. Intermittent wipers, a tachometer, a temperature readout, a first aid kit, and a front power outlet are also standard. A navigation system, DVD player, rear spoiler, and wood trim are all available options.
