Classified as a midsize luxury sedan, the 2013 Infiniti M is available in three trim levels that correspond to engine choices: M37, M35h and M56.
Standard on the M37 are 18-inch alloy wheels, automatic bi-xenon headlights, foglights, power-folding heated and auto-dimming mirrors, automatic wipers, a sunroof, a power soft-closing trunk lid, keyless ignition/entry, dual-zone automatic climate control, leather upholstery, heated eight-way power front seats with power lumbar support, driver memory functions and a power tilt-and-telescoping steering column. Also standard are a rearview camera, Bluetooth and a six-speaker stereo with a CD player, auxiliary/USB/iPod inputs, an audio/visual jack and satellite radio.
With the M35h you get all the standard features offered with the M37, along with a hybrid powertrain and unique instruments and display screens.
The M56 adds rear parking sensors, a navigation system, real-time traffic and weather updates, voice recognition, heated and cooled front seats, a heated steering wheel and a Bose 10-speaker premium audio system with digital music storage. All of these additions are available on other trims as part of the optional Premium package.
Most options are bundled in packages that add to the Premium package, and are not compatible with all other options. The Deluxe Touring package is offered on all trims and adds a power rear sunshade, an air purifier, upgraded leather upholstery and interior trim, and a 16-speaker Bose audio system. Also available is the Technology package, which adds adaptive cruise control, a lane departure warning and prevention system, a blind-spot warning system, a forward collision warning system, adaptive headlights and the "eco pedal" that provides feedback to the driver to encourage fuel-efficient driving.
The M37 and M56 each offer a Sport package, although the content varies between trims. The M37 package includes 20-inch wheels, summer tires (all-season performance tires for AWD models), sport-tuned suspension and brakes, four-wheel active steering (rear-drive models only), sport seats and steering wheel, and unique exterior styling elements.
Stand-alone options are few and include a rear deck lid spoiler and an aerodynamic body kit.
