The Infiniti M, sold from 2013 as the Q70, was the brand’s mid-size luxury flagship. The Q70 was essentially an update of the M with minor cosmetic changes, renamed to fit Infiniti’s new “Q” nomenclature.

The M nameplate was renamed Q70 in 2013; this article covers the M and Q70 flagship together.

History of the Infiniti M (Q70)

The Q70 name arrived in 2013, when the whole Infiniti range was renamed: the M sedans became the Q70, a name that reflected the model’s position in the line-up rather than its engine size, as the old names had done. The car was essentially an updated M with minor cosmetic changes, and the M itself was based on the Japanese-market Nissan Fuga; the line’s engines had been named M37, M56, M35h and M30d on that basis.

In the United States the Q70 went on sale for the 2014 model year in 3.7, 3.7 AWD, 5.6, 5.6 AWD and Hybrid forms, all with a seven-speed electronically controlled automatic with Adaptive Shift Control and a manual mode. Chinese sales had begun in 2012. European deliveries started in December 2014 with the 2.2d diesel and the Hybrid, and British sales followed in 2015 with the 2.2d, the 3.7 of 320 PS and the 364 PS Hybrid.

The 2014 facelift brought new front and rear fascias, a new grille, Infiniti’s signature LED headlights and tail lights, LED fog lights, mirrors with integrated indicators, three new body colours, revised 18-inch wheels, optional Backup Collision Intervention and standard Active Noise Control. The long-wheelbase Q70L, shown in 2015 and based on the Nissan Cima, added “sword brow” daytime running lights, semi-aniline leather, electrically operated rear doors and boot, and a rear entertainment system. In 2019 Nissan confirmed that the Q70, Q70L, Q30 and QX30 would be discontinued after the 2019 model year because buyers in Canada, Mexico and the United States preferred crossovers; the Q70L continued in China. Recalls affected 2014 hybrid cars with potentially damaged motor housings or a software fault, and 2014–15 cars with fuel pressure sensors that might not be tight enough.
