Ironically, the replacement of the Infiniti original Q45 sedan received the ‘Q' branding through the use of a new fleet wide naming structure for the 2014 model year. Known as the M37 and M56 in 2013, both versions of Infiniti's top level sedan is consolidated under the Q70 name. Boasting the brand's greatest comfort and technology, the Infiniti Q70 sedan's standard features included high-end touches such as HID headlights, rain-sensing windshield wipers, power moonroof, Active Noise Control and leather interior. A 16-speaker Bose Surround sound system, Blind Sport Intervention, intelligent cruise control and a Forest Air system with Plasmacluster air purifier are some of the standout options on the Q70. Offered with rear-wheel drive or all-wheel drive configurations, engine performance for the sedan is supplied by either a 330-horsepower 3.7-liter V-6 or 420-horsepower 5.6-liter V-8 engine. In 2015, front and rear styling of the Infiniti Q70 underwent a make-over adding LED headlights as well as a new grille. Among changes, base trim model seating upholstery changed from leather to leatherette. A Premium Select Edition package was incorporated on the 2016 Infiniti Q70 adding laser-etched aluminum trim, 20-inch wheels and special seating colors.
