As luxury flagships go, the Q70 is stylish and quite voluptuous, but good looks and a fetching interior aren’t enough to steal the spotlight from fresher foes. A 330-hp 3.7-liter V-6 or even more potent 420-hp 5.6-liter V-8 powers the rear wheels through a seven-speed automatic. All-wheel drive is optional. A hybrid model pairs a 3.5-liter V-6 with an electric motor for 360 hp and a stretched Q70L model adds 5.9 inches of rear leg room and extra luxury features for rear-seat passengers. The Q70 is the queen of Infiniti’s passenger-car fleet, a big sedan with a distinctive presence, two available wheelbases, gracious interior appointments, and respectable powertrain choices, including all-wheel drive and a hybrid. But in a segment chockablock with stimulating sports sedans, it rates as no more than an also-ran.
The Q70 rolled into the 2015 model year with a freshening—revised front and rear fascias and the addition of the long-wheelbase version tested here—that moved it cosmetically closer to the smaller Q50. This is not a bad thing. Infiniti has done a good job creating a readily recognizable face for its offerings without resorting to excesses such as the Lexus spindle grille.
Inside the Q70—which debuted back in 2011 as the M37/M56—came tweaks to content and trim, including some very tasty white ash accents in our test car, relaxed-fit seats well suited to a dash from Atlanta to Abilene, and plenty of tech features. Our test car also packed $8350 in options, most devoted to making long treks more pleasant as well as more connected.
