As luxury flagships go, the Infiniti Q70L 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.
