The 2018 Infiniti Q70 is offered in two wheelbases and three different trims: Q70 3.7, Q70 5.6, and Q70 Hybrid. A 330-horsepower, 3.7L V6 engine is included with the Q70 3.7, while the Q70 5.6 upgrades to a 420-horsepower, 5.6L direct-injected V8. The Q70 Hybrid features a 360-horsepower 3.5L V6, along with an electric motor and can run on either one of its power sources at any given time. All models come with a 7-speed automatic transmission that has downshift rev matching and manual shift control. All-wheel drive is available in a road-performance-oriented system that can send up to 50 percent of torque to the front wheels. All but the hybrid model are available in both 114-inch and 120-inch wheelbase lengths. The longer wheelbase's extra length is focused toward the rear seat occupants, giving them even more legroom than before.

A system called Infiniti Drive comes in all Q70 models and includes four modes (Standard, Eco, Sport and Snow) to help tailor throttle and transmission response to various road conditions. In Eco mode, the system will actually push back if the vehicle is being driven in a non-efficient manner.

The Q70 sedans get a front double-wishbone and rear multi-link suspension setup, bringing responsiveness as well as composure over rough surfaces. Thanks to a series of underbody panels and well-designed aerodynamics, the Q70 sedan has a very low coefficient of drag, which especially helps with highway fuel efficiency.

All Q70 sedans have the same interior. There is space for three adults in back, and leather upholstery and wood accents nicely bridge the divide between conservative and sporty. Through packages and standalone options, the interior can be appointed with several distinct themes. Soft, full-grain leather modeled after premium sofa material is included with the Deluxe Touring Package, which adds leather to the arm rest and center console, while heated seats, rear backup sonar and ventilated front seats come with the Premium Package. The instrument-panel design includes electroluminescent gauges and a Plasmacluster air purifier and humidity control help keep the air fresh. A Performance Tire & Wheel Package with 20-inch wheels and tires is also available.

Infiniti's Q70 sedans include plenty of conveniences standard, including a rain-sensing wipers, heated mirrors, a USB port and iPod connection, Bluetooth, an Intelligent Key system and a garage-door opener. Many of the more exciting tech features are included in a Technology Package, which includes a Blind Spot Warning system that will alert the driver if there's a vehicle just beside and behind, while Blind Spot Intervention takes it a step further, selectively braking each wheel to help nudge the driver back into the lane.

The Q70 is available with a host of other tech features, including Active Noise Control, which helps quiet cabin noise without heavy noise insulation and a Forest Air system that further deodorizes the air from the climate-control system. Intelligent Brake Assist with Forward Collision Warning is another system designed to help avoid accidents. The Q70 Hybrid comes with Blind Spot Warning, navigation, heated steering wheel, cooled front seats, and Lane Departure Warning as standard features, and several unique trims are available.

Infotainment content looks great on the 8-inch display. The navigation system comes with XM NavTraffic, NavWeather and Zagat restaurant ratings. The 10-speaker Bose sound system includes streaming audio capability as well as a 9.4GB Music Box hard-drive music-storage system.
