Attractive styling, a comfortable interior, and excellent performance make the 2018 Infiniti Q50 a compelling value. A surprisingly affordable starting price has also helped make the Q50 Infiniti’s best-selling model.

The Q50 seats five, and is sold in Pure, Luxe, Sport, Red Sport 400, and Hybrid models. Powertrain choices include a turbocharged four-cylinder engine, two turbocharged V6 engines, and a hybrid variant. A seven-speed automatic transmission is standard with rear-wheel or all-wheel drive.

For 2018, the Q50 receives a mild refresh with revised front and rear fascias and new taillights. The interior is also updated with revised seating, a new steering wheel, shift knob, upholstery and trim.


A cautious styling evolution modernizes the Q50’s sporty, attractive appearance while maintaining its athletic persona. Like previous models, the Q50 makes a strong visual statement without making a scene. For 2018, Sport and Red Sport 400 are differentiated with a unique front fascia, bolder bumper design, and larger air intakes.

The base Pure trim comes with 17-inch alloy wheels, LED lighting, heated outside mirrors, rain-sensing windshield wipers, and dual chrome exhaust tips. Exterior upgrades include 18- or 19-inch wheels, power mirrors with reverse tilt-down, high beam assist headlights, and trim-only exterior treatments.


The interior of 2018 Q50 features high-quality materials. The fit and finish are superb, providing the driver and passengers with a premium experience. The stock seats are comfortable and highly adjustable. The leather-wrapped steering wheel and shift knob look great and are comfortable to the touch. The Q50’s intuitive controls are thoughtfully implemented.

The Q50’s rear seat is spacious, especially for the small premium sedan segment. The seating can accommodate three adult passengers, adding to the versatility of Infiniti’s family-friendly sedan.

Trunk space measures from 13.2 to 13.5 cubic feet depending on trim level, which is consistent with other vehicles in the segment. The optional 60/40 split folding rear seatbacks enhance the Q50’s practicality by providing additional storage flexibility.

Base Q50 models include leatherette upholstery and Lunar Black trim. Eight-way power-adjustable seats, push-button start, cruise-control, a manual tilt-and-telescopic steering column and dual-zone automatic climate control are also standard. Available options include heated front seats, upgraded trim, a heated steering wheel, power tilt- and telescopic steering column, and an auto-dimming rearview mirror with a garage door opener.


The base 2018 Infiniti Q5 is powered by a turbocharged 2.0-liter four-cylinder engine that produces 208 horsepower and 258 pound-feet of torque. Most Q50’s are sold with a 3.0-liter twin-turbocharged V6 under the hood and creates 300 horsepower and 295 pound-feet of torque. Red Sport 400 models also get a 3.0-liter twin-turbocharged V6, but rated at 400 horsepower and 350 pound-feet of torque. The Q50 Hybrid uses a 3.5-liter V6 and electric motor to produce 360 horsepower.

All Q50s employ a seven-speed automatic transmission with paddle shifters. Rear-wheel drive is standard; all-wheel drive is a $2,000 option on all models.

Fuel economy is dependent on the driveline. Q50 Pure models with the four-cylinder engine get an EPA-estimated 23/30 mpg city/highway with rear-wheel drive, 22/28 mpg with all-wheel drive. Opt for the V6 and you can expect 20/29 mpg with rear-wheel drive, 19/27 mpg with all-wheel drive. The Q50 Red Sport 400 returns 20/26 mpg city/highway with rear-wheel drive, 19/26 mpg with all-wheel drive. Not surprisingly, the Hybrid returns the best fuel economy: 27/32 mpg with rear-wheel drive, 26/30 mpg with all-wheel drive. All models require premium fuel.

As tested, the Q50 Red Sport 400 proves that Infiniti competes with the finest European sport sedans by offering excellent performance and premium comfort. The turbocharged V6 is powerful, and the fast-shifting seven-speed automatic is rewarding. The all-new dynamic digital suspension keeps the Q50 stable, even when pushed around tight corners and over uneven pavement. The system provides the Q50 Red Sport 400 with a dual personality, soft and forgiving for daily commutes and taut and responsive when spirited driving is needed.

Our only complaint centers on the electric power steering. Even the much improved direct adaptive system feels artificial at times, almost like you are controlling the car with a video game controller rather than with a rack-mounted steering box.


The 2018 Infiniti Q50 includes a six-speaker single-CD audio system with a dual display. The center-console-mounted screens feature an upper eight-inch infotainment display and a lower seven-inch display. Infiniti’s base infotainment system includes satellite radio, voice recognition, USB and Bluetooth connectivity. Unfortunately, the Infiniti Q50 does not include Apple CarPlay/Android Auto smartphone integration, even as an option.

Our Red Sport 400 review vehicle includes a $2,650 Sensory Package that features a 16-speaker Bose surround sound system. The package also includes a power tilt and telescopic steering column, dual-memory seats, advanced climate control, ambient lighting and auto-dimming outside mirrors.


Standard safety technology includes brake assist, vehicle dynamic control, tire pressure monitoring and a rearview camera. Available driver-assistance features include a parking system with an around-view monitor, front seat pre-crash seats, back up collision intervention, predictive forward collision, forward emergency braking, blind spot warning, and lane departure warning.


The 2018 Infiniti Q50 starts at $34,200 plus a $995 destination and handling charge. The Q50 Red Sport 400 and Q50 Hybrid Luxe start at $51,000 and $50,600 respectively. All-wheel-drive can be added to all models for $2,000.

Our test Q50 Red Sport 400 included the Sensory Package ($2,650), a Proactive Assist Package ($2,700), illuminated kick plates ($465), a radiant grille emblem ($400), a spare tire package ($300) and exclusive paint ($800). After destination, our 2018 Infiniti Q50 Red Sport 400 Prestige had a suggested price of $60,720.

While we are enthralled with the power and performance of the Red Sport 400 model, our advice is to investigate the 3.0t Sport model. The $40,650 starting price is a relative bargain in the luxury sport sedan market and the 300-horsepower twin-turbo V6 engine provides more than enough power and excitement for most enthusiasts.


Thanks to Infiniti’s thoughtful refresh, the 2018 Infiniti Q50 is more attractive than ever. The exterior styling is sporty but restrained while the interior offers a high level of luxury at an affordable price. Choosing a higher trim level allows consumers to decide where to spend their money. Infiniti’s thoughtful packaging bundles key performance and luxury items, taking away much of the guesswork.
