When Nissan’s luxury division first emerged in the 1990 model year, the lineup included a big Q45 sedan and an M30 coupe. By 1993, the M30 was gone; but a decade later, the “M” prefix returned on an M34 sedan. INFINITI revised its model-name pattern for 2014, adopting a “Q” prefix for all passenger cars. The two-digit numerical suffix denoted that model’s position in the lineup. Thus, without changing significantly, the M37 and M56 sedans turned into a pair of range-topping Q70 models, powered by either a V6 or V8 engine.
What's New for 2017
Little has changed for the 2017 model year. A Premium Select Edition joined last year, and is now available for the long-wheelbase Q70L sedan (which is listed separately).
Choosing Your INFINITI Q70
Owners only need to make one main choice: deciding on the amount of power. INFINITI offers two trim levels, identified by engine size. The base 3.7 model comes with a solidly competent 3.7-liter V6 that delivers 330 horsepower and 270 pound-feet of torque. The optional engine in the 5.6 trim level is a 5.6-liter V8 that generates 420 hp and 417 lb-ft. Both engines mate with a seven-speed automatic transmission, and both can have all-wheel drive as an alternative to standard rear-drive.
Fuel economy with the V6 is estimated at 18 miles per gallon city, 25 highway, and 21 combined, according to the EPA. All-wheel drive drops the estimate to 18/24/20 mpg. The EPA estimates the V8 will return 16 city, 24 highway, and 19 combined with rear-drive, or 16, 23, and 18 mpg with all-wheel drive.
A selection of option packages is available for the Q70 3.7, one of which costs nothing extra:
The complimentary Premium Package adds navigation with real-time traffic and weather, a Bose 10-speaker stereo, INFINITI Connection telematics, leather-appointed seating, heated steering wheel, front/rear parking sensors, and a 360-degree parking camera.
Premium Select Packages have dark chrome exterior trim, a rear spoiler, unique 20-inch wheels, a suede-like headliner, and aluminum interior trim.
The Technology Package adds a number of active safety features, including blind-spot warning and intervention, lane-departure warning and prevention, adaptive cruise control, forward-collision warning, and backup-collision intervention.
The Sport Touring Package includes Bose surround sound and a power rear sunshade.
The Sport Package adds a sport-tuned suspension, 20-inch alloy wheels, sport brakes, enhanced seat bolstering, magnesium paddle shifters, aluminum pedal accents, and a unique front fascia.
Especially because of the significant features included in the free Premium package, it pays to compare the total price of a 3.7, with preferred option packages, against the cost of a Q70 5.6. A 3.7 with every available option may be less expensive than the 5.6 in base form. Unless flat-out performance is the primary goal, we question the value of paying an additional $13,000 for the 5.6-liter engine.
