2015 Infiniti Q70 First Look

Motor Trend logo Motor Trend 4/16/2014 Jason Udy

Just a year after the Infiniti M Line adopted the premium automaker’s new nomenclature, the 2015 Infiniti Q70 sedan is getting an extensive refresh -- as well as a new long-wheelbase version dubbed the 2015 Infiniti Q70L. With a 5.9-inch longer wheelbase, the Q70L is almost as roomy as many full-size luxury sedans. The 2015 Infiniti Q70 debuts at the 2014 New York auto show.

Up front, a new “double arch” grille with “waved mesh” finish and chrome surround and LED headlights give the Q70 sedan a three-dimensional look. The redesigned front bumper features integrated fog lights. A distinct wave-like bodyline rises from the grille and flows down the side to meet the revised LED taillights and give the luxury sedan a sporty profile. Around back, the taillight’s new horizontal shape, flatter trunk lid with chrome strip, and revised bumper give the Q70 a wider and sportier visual stance.

Both front seats are heated and feature 10-way power adjustment including two-way lumbar. With a 5.9-inch-longer wheelbase, the 120.1-inch wheelbase Q70L sedan has an additional 5.9 inches of knee room and 5.6 inches of leg room for a total of 32.5 inches and 41.8 inches, respectively, over the standard 114.2-inch wheelbase Q70. Infiniti claims the additional length enables back seat passengers to comfortably cross their legs. Long-wheelbase models also feature heated rear seats, rear reading lamps, a rear 12-volt power outlet, and rear door auto closure.

More sound deadening material, better seals, and stiffer wheels further isolate the interior from road noise. The Q70 also uses to Active Noise Control that uses the door speakers to cancel out droning frequencies.

Fine Vision gauges and a seven-inch full-color vehicle information display dominate the instrument cluster, while a 5.1-channel, 16-speaker Bose Studio Surround sound system provides the music. Other features include Bluetooth phone, dual-zone climate control, and Infiniti Connection telematics services. A hard-drive-based navigation system with eight-inch color touchscreen is available. An Enhanced Intelligent Key remembers each driver’s last settings for audio, navigation, and climate control settings.

While the interior and exterior have been significantly updated, the Q70 soldiers on with the same powertrains as before. The 330-hp 3.7-liter V-6 with 270 lb-ft of torque is the base engine, while a 420-hp, 417 lb-ft 5.6-liter V-8 is available. (The 5.6-liter in the Q70L makes 416 hp and 414 lb-ft.) A hybrid version is available for the standard wheelbase Q70, but not for the Q70L. That powertrain consists of a 302-hp, 258 lb-ft 3.5-liter V-6 and a 67-hp, 214 lb-ft electric motor. Total power output is rated 360 hp. A seven-speed automatic with available paddle shifters backs all three powertrains. Rear-drive is standard, while all-wheel drive is available on all but the hybrid model. The Q70 features four drive modes (Standard, Eco, Sport, Snow) depending on driving conditions.

The suspension system is largely carried over, though it features new dampers for improved ride quality, while the steering is a speed-sensitive electronically controlled rack-and-pinion system. The steering system is augmented by Vehicle Dynamic Control with Traction Control System that adjusts engine torque and braking during spirited cornering.

Available safety features include Lane Departure Warning and Lane Departure Prevention, Blind Spot Warning and Blind Spot Intervention, and Cruise Control and Distance Control Assist as well as the Infiniti Safety Shield, which includes Predictive Forward Collision, Around View Monitor, Backup Collision Intervention, and Forward Emergency Braking systems. 2015 Infiniti Q70 Interior© Provided by MotorTrend 2015 Infiniti Q70 Interior 2015 Infiniti Q70L Interior Front Seats© Provided by MotorTrend 2015 Infiniti Q70L Interior Front Seats
