2013 Infiniti M Overview

Is the 2013 Infiniti M a Good Used Car?

The 2013 Infiniti M features quick acceleration and unusually sporty handling for a large car, making it a great option for performance lovers seeking both power and agility. However, its firm ride and poor fuel economy make it less than ideal for daily driving. It also has below-average trunk space for the luxury large car class.

Used 2013 Infiniti M Performance and Interior

The rear-wheel-drive 2013 Infiniti M37 has a muscular 330-horsepower V6 engine that delivers speedy acceleration. The Infiniti M56 has a more potent 420-horsepower V8 engine. Both models come with a seven-speed automatic transmission and are available with all-wheel drive. Fuel economy for both models is among the worst in the class. According to the EPA, the base M37 gets 18 mpg in the city and 26 mpg on the highway, while the M56 earns 16/24 mpg city/highway.

The Infiniti M handles more like a sports car than a sedan, with excellent cornering composure and tight steering. However, its agility comes with a firm ride quality, particularly in models with the available sport-tuned suspension.

The four-door, five-seat 2013 M sedan has an attractive cabin with top-notch materials and straightforward styling. The front seats provide a good amount of head- and legroom. The sedan’s low roofline makes for poor rear-seat headroom, though tall passengers should find plenty of rear-seat legroom. The Infiniti M’s 14.9-cubic-foot trunk is on the small side for the class. There are two complete sets of LATCH child-seat connectors on the outboard seats, as well as an upper tether anchor for the middle seat.

Standard features include a USB port, Bluetooth phone connectivity, push-button start, and a 7-inch display screen. Available features include a premium Bose surround-sound audio system, voice-controlled navigation, and a number of active safety features. The infotainment screen is controlled via physical buttons and on-screen menus. It’s one of the easier screens to navigate.

Is the 2013 M the Best Model Year to Buy?

The 2013 model marked the Infiniti M’s final year of production. Prior to that, the car was completely redesigned for 2011. If you’re looking to save some money, consider a 2011 or 2012 model. There were few changes between 2011 and 2013, so you won’t miss out on many features by opting for one of the earlier model years. In 2014, the car was rebranded as the Infiniti Q70.

Which Used Infiniti M Is Right for Me?

The 2013 Infiniti M comes in two trims: M37 (base) and M56. The 2013 M37 comes with a strong V6 engine and plenty of standard features, including a power moonroof, leather upholstery, heated front seats, a USB port, Bluetooth phone connectivity, satellite radio, a rearview camera, a proximity key, push-button start, and a 7-inch infotainment display screen. Most shoppers should be pleased with this model.

If you’re looking for more power, you’ll find it with the M56’s V8 engine. This trim also adds heated and cooled front seats, a 10-speaker Bose sound system, Bluetooth audio, voice-controlled navigation with an 8-inch touch-screen display, a heated steering wheel, and rear parking sensors.

You may also want to consider a certified pre-owned M. The Infiniti CPO warranty has three levels of coverage based on the vehicle’s age and mileage. Vehicles with less than 15,000 miles receive a six-year/75,000-mile warranty from the original new-car purchase date. Vehicles less than four years old with more than 15,000 miles receive a six-year/unlimited-mileage warranty from the original new-car purchase date. Finally, vehicles more than four years old with more than 15,000 miles receive a two-year/unlimited-mileage warranty good from the CPO purchase date. Infiniti CPO vehicles must pass a 167-point inspection. Additional benefits like towing and roadside assistance may be available, so read the Infiniti warranty page carefully. The model's original sale date determines whether it is eligible for the CPO program.

2013 Infiniti M and Other Cars to Consider

Which Is Better: 2013 Infiniti M or 2013 Hyundai Genesis?

The Hyundai Genesis has a standard V6 and an available V8 that are roughly equal in power to what the Infiniti M offers. The Genesis isn’t as nimble as the M37, but it features a softer ride quality and a couple more mpg on the highway. It also has a roomier back seat and a bit more trunk space. Go with the Hyundai.

Which Is Better: 2013 Infiniti M or 2013 Volvo S80?

If you want ride comfort, the Volvo S80 is the way to go. The S80 is also available with more safety features than the M37, including pedestrian detection and a driver alertness monitoring system. However, performance enthusiasts will prefer the Infiniti M’s sporty handling and more powerful engines.
