2009 Infiniti M45 Review

Packs a bigger, and more silent, wallop.

Reviewed by Automotive on

Overview

The 2009 Infiniti M45 contains a 4.5-liter V-8 engine with 325 horsepower. This ""M,"" as Infiniti calls it, marks the fastest generation of its kind.

Aside from the now-standard auto-speed-sensing locks and a Drive Sport (DS) shift mode, the 2009 M45 adds several new features. An independent double wishbone design in front, multi-link setup in back, and added stabilizer bars promote responsive handling. An all-wheel drive (AWD) system adapts to road situations and optimizes traction. Climate controls and luxury add-ons, such as Bluetooth and intelligent cruise control, make for a safer ride. Add a Sports Package and heated power-reclining seats, and drivers will find it hard to leave their cars.

The M45’s lane departure prevention system marks the hottest new addition, with a camera and brake controls to stop drivers from meandering into other lanes or into oncoming traffic.

The Range

Body styles: four-door sedan
Engine: 4.5-liter V-8
Transmissions: six-speed automatic, six-speed manual
Model: Infiniti M45

What's New

Infiniti expands the ""M"" lineup with the M45 model for those desperate (and willing to pay) for more horsepower.

A Sports Package features interior and exterior appearance enhancements as well as larger 19-inch wheels and tires. It also adds a rear active steering system for better handling.

Lane departure prevention technology premiered worldwide with Infiniti’s EX35 SUV and also comes in the 2009 Infiniti M45. The technology uses a small camera to detect when drivers stray from their lanes. It then automatically triggers slight brake pressure on the opposite wheels, causing the M45 to glide back into its appropriate lane.

Other changes include standard auto speed-sensing locks, a DS shift mode for all transmissions, and a Scratch Shield self-mending clear-coat finish. Customers can also opt for a hands-free Bluetooth system and electronic and sound system upgrades, like the Bose surround sound with 14 speakers. A rear-view monitor and intelligent cruise control features also make for an uncluttered driving experience.

Exterior

A mix of sport sedan and posh luxury car, the four-door 2009 Infiniti M45 offers an affordably fun time. It also looks sleek and will stay that way thanks to the standard Scratch Shield self-mending clear-coat finish. The doors, hood, and trunk lid are made of aluminum, which helps save on gas and increases responsiveness. To balance safety and power, Infiniti adds an independent double wishbone design in front and multi-link setup in back with stabilizer bars for responsive handling.

Interior

Space in the 2009 Infiniti M45 suffers slightly with only modest headroom. The trunk space also suffers due to the lack of space for ski and board toters. Back-seat passenger seating remains cozy. Infiniti updates the interior with a splash of electronic gadgets and climate control amenities, while retaining attractive leather upholstery and chic rosewood or aluminum trim.

Performance & Handling

Even the base 2009 Infiniti M45 and its 4.5-liter V-8 offer enough power almost effortlessly to pass large vehicles. The suspension glides over road obstacles with minimal engine, road, and wind noise. The M45’s small storage space limits outing choices, especially for sporty folks with big space requirements.

Safety

The National Highway Traffic Safety Administration awards the 2009 Infiniti M45 five-star ratings in several categories, including driver front impact and rollover categories. The M45 comes standard with anti-lock disc brakes (ABS) and features electronic brakeforce distribution as well as a shift interlock system. The M45 also includes a vehicle dynamic control and traction control system. An emergency inside trunk release keeps children safe, along with child safety rear door locks and a rear-seat LATCH system. Also standard are dual driver, dual-stage frontal, side impact, and head curtain side airbags, along with brake-activated pre-crash front seat belts. The front seat offers active head restraints. The M45 also contains a first aid kit in the rear center armrest.
