The Q50 for 2018 comes in a dozen different ways. The Q50 designation is followed by the power source indication: 2.0t represents a 2.0-liter turbocharged inline four-cylinder.; 3.0t is for the 3.0-liter twin turbo, 300 horsepower V6; (there’s also a 3-liter twin-turbo V6 that puts out 400 horses); and a Hybrid 3.5-liter V6. Confused yet? It gets better – the 2.0-liter comes on two levels of trim – Pure and Luxe, with each available in either RWD or AWD. The 300 horse V6 is available in Luxe or Sport trim in both RWD and AWD. The 400 horsepower V6 is designated as the Infiniti Q50 Red Sport 400 in both RWD and AWD configurations. The Q50 Hybrid comes in Luxe trim only and may ordered as a rear or all-wheel drive. The 2018 Infiniti Q50 3.0t Red Sport 400 will be the subject of this review.

The Q50 lineup is Infiniti’s top selling vehicle, and pricing will range from $34,200 for a 2.0t Pure Q50 RWD to $51,000 for a Red Sporty 400 RWD. Add another $2,000 to all models for AWD along with a $950 Destination Charge for all Q50s. My test 2018 Infiniti Q50 3.0t Red Sport 400 sedan’s base price was set at $51,000 which rose to $60,720 after factoring the following added costs: the Sensory Package; the Proactive Package; Infiniti Illuminated kick plates; Infiniti Radiant Grille Emblem; Spare tire Package, Exclusive Paint; Carbon Fiber Package; and Destination charges.

2018 Q50 models connect Infiniti’s refined 7-speed automatic transmission with available solid magnesium paddle shifters to all powertrains. The Infiniti Drive Mode Selector offering Snow, Eco, Standard, Sport and Personal settings is also standard on all models, part of the Infiniti InTuition System, an advanced customizable digital environment system allowing drivers to create unique settings for engine, suspension and steering (when equipped with Infiniti Direct Adaptive Steering) settings.

Other available advanced drivetrain technologies include Infiniti’s steering mode selections, accessed through the Drive Mode Selector on the center console, which allows the level of steering responsiveness to be selected from six available options: Personal, Standard, Snow, Eco, Sport, and Sport+. It is available on all 3.0- liter V6-equipped models as part of the new ProActive Package.

The Q50’s refreshed styling cues coincide with the latest global grade naming structure: Pure, Luxe, Sport and Red Sport 400. Option package content and labeling has also been upgraded for 2018.

The sensory pleasure of driving is not a problem with the new Infiniti 3.0t Red Sport 400. Defining the proper category in which to place is another story – is it a Sport sedan, a luxury sedan, or a blend of the two. I place it in the latter category as it is both sporty and luxurious, not to mention being on the same level as several German competitors as well as other Asian brands.

Whether charging over the scenic, twisty back roads of Tennessee or negotiating truck traffic laden freeways, the Red Sport 400 shines on all fronts. The ride quality is comfortable, yet taut and stable even in demanding scenarios. Handling characteristics are athletic and instantly responsive.

Place this Infiniti luxury hot rod sedan in the Sport+ mode and prepare for an e-ticket –like ride that’s sure to satisfy one’s motor senses. (pun intended). There’s a lot of really tough competition on the playing field with the Red Sport 400, but it’s definitely capable of holding its own and it lives up to the sporting heritage of the Prince R380 – one of the first purpose-built Japanese race cars and winner of the 1966 Japanese Grand Prix.


The new Q50 cabin’s artistic level has also been enhanced, providing a more comfortable and a more high-tech connected space. The new grade structure has enabled Infiniti designers to differentiate each model with its own unique interior flavor.

Significant interior enhancements include unique stitching on premium and soft-touch materials surrounding the instrument panel and a sport-oriented leather shift knob. Seating features Infiniti’s spinal support seats that ensure a comfortable and supportive ride. The steering wheel is new featuring molded positions for the driver’s thumbs and Infiniti InTouch Services designed to effortlessly bring the car and driver in synch.

Driver assistance technologies include: available Direct Adaptive Steering, Active Lane Control, Intelligent Cruise Control, Distance Control Assist, Backup Collision Intervention, Blind Spot Warning and Intervention, Lane Departure Warning and Prevention, Forward Emergency Braking, and Predictive Forward Collision Warning.

TFLCAR’s TAKE: The 2018 Infiniti 3.0t Red Sport 400 is an excellent example of Japanese design, engineering, technology and craftsmanship that delivers a complete suite of safety and connectivity features, along with stellar performance qualities. In essence, It is clearly a winner.
