2018 INFINITI Q50
The 2018 Infiniti Q50 is a powerful and well-equipped luxury sedan. Despite just receiving a minor facelift, the 2018 Infiniti Q50 remains the brand’s best-selling car. Only a 2.0-liter turbocharged inline-4 engine is offered in the Q50 Pure. The Q50’s Luxe trim replaces the Premium and is expected to be the most popular option. Infiniti’s 3.0-liter, twin-turbocharged V-6 or V-6-hybrid powertrains are all options, as is the 2.0-liter turbo-4. The Red Sport 400 continues with a 400-horsepower V-6 in Sport, while the basic V-6 is retained in the Sport.
The 2018 INFINITI Q50 is offered in 7 trim levels:
- 2.0T Sport
- 2.0t PURE: 7-Speed A/T
- 2.0t LUXE: 25 combined MPG
- 3.0t LUXE: 23 combined MPG
- 3.0t Sport: 22 combined MPG
- 3.0t Red Sport 400: Rear Wheel Drive
Performance and Fuel Economy
The engines are the same for the new model, starting with a turbocharged 2.0-liter four-cylinder that generates 208 horsepower. A turbocharged 3.0-liter V-6 generates 300 or 400 horsepower depending on the trim level, while the Q50 Hybrid’s normally aspirated 3.5-liter V-6 and electric motor provide 360 horsepower. Seven-speed automatic transmissions are available with either rear or all-wheel drive for all engines. Infiniti has reworked the 2018 Q50‘s front and rear stabilizer bars and adaptive shock absorbers are available as an option for the model.
The Q50 strikes an excellent mix between agility and comfort throughout the driving experience. If pushed aggressively, the body’s reaction is predictable, rolling gradually with increasing steering angle and inclining toward understeer. It does all of this without harassing the driver or passengers. But the Q50’s chassis is likewise lacking in feedback. Because of the way the weight moves laterally, fore and aft, it might be difficult to see what is going on through the seat of the trousers. The Q50 is almost too cushy, although we doubt you’ll have an issue with that if you don’t often tackle back roads.
With all-wheel drive, the Luxe and Sport get 19/27/22 mpg, while the V-6-powered Luxe and Sport get 20/29/23 mpg. It gets 20/26/22 mpg with its turbocharged 400-hp Red Sport 400. City mileage is reduced by one mpg when all-wheel drive is added, but the highway and combined figures remain the same.
Design, Comfort, and Quality
The improvements to the 2018 Infiniti Q50 are minor, as is typical for a refresh, but the Red Sport, which Infiniti aimed to set apart from the rest of the range, shows them off. Its foglights have a thinner framework that blends into opposing ground effects, while the lower aperture on the front bumper has sculpted creases that give it a smiling appearance. Back there, the Red Sport features contrasting lower trim and a conspicuous low diffuser, which continues the concept. A more cluttered, aftermarket-modified appearance may be deemed garish by some. Nevertheless, if you felt the Red Sport 400 was too mild last year, this is the antidote you need.
Besides a slightly smaller hub, the Q50’s new steering wheel is almost unchanged from its predecessor. Stitching has been added to the dashboard, but the car’s dual-screen entertainment system remains. Unique red stitching and quilted leather seats are seen on Red Sport variants. The Bose Performance Series premium stereo is an optional accessory. Despite Infiniti’s best efforts, the Pure/Luxe and Sport models of the Q50 seem to have a bigger visual gap than most of the Q50’s rivals do.
Body-colored exhaust tips and chrome-accented fascia distinguish the Pure and Luxe trim levels from the rest of the lineup. Smaller foglight surrounds are standard, as are 17- or 18-inch alloy wheels. The Sport and Red Sport 400 have dark chrome instead of regular chrome, a larger front chin spoiler and foglight surrounds, black mirror caps, standard 19-inch wheels, and a black exhaust surround.
