2015 Infiniti Q70L 3.7

The 2015 INFINITI Q70L 3.7 is a long-wheelbase luxury sedan designed to blend performance, comfort, and executive-level rear-seat space. For 2015, Infiniti introduced the Q70L, stretching the wheelbase by nearly six inches to dramatically increase rear legroom—an upgrade that transforms the back seat into a genuinely spacious, almost limousine-like environment. Under the hood, the Q70L 3.7 carries a 3.7-liter V6 engine producing 330 horsepower and 270 lb-ft of torque, paired with a 7-speed automatic transmission for smooth, confident acceleration. Inside, the cabin is well-appointed with premium materials, dual-zone automatic climate control, Bluetooth, navigation, rain-sensing wipers, and a suite of comfort-focused amenities such as power accessories, Homelink, and front/rear cupholdersCarsDirect. The ride leans toward the firm side more sport-luxury than soft cruiser and while the V6 is strong, some reviewers note it feels less refined compared to rivals. Still, the Q70L stands out for its solid build quality, generous feature set, and especially its expansive rear seating, making it an appealing choice for buyers who want a driver-focused luxury sedan with true executive-class passenger space.
