For 2018, INFINITI has revised the sedan's look with a few new alterations. The entire lineup of Q50 sedans benefit from the automaker's signature double-arch grille, LED headlights, and slim LED taillights. Specific models get bigger changes, including the 3.0t Sport and Red Sport 400, which get a revised front fascia that has a wider, lower bumper and larger air intakes that are integrated lower on the bumper. The rear end of the sedans also received new touches, which includes dark metallic trim near the bottom of the rear bumper.
The Q50 Red Sport 400 also obtains bespoke 19-inch wheels, while the rest of the lineup, with the exception of the base Q50 2.0t Pure model, get a moonroof and heated exterior mirrors as part of their standard features.
The interior of the Q50 gets some new touches, as well, with leather-like materials with double stitching surrounding the instrument panel, while new wood trim is adorned on the dashboard. The sedan also received some sportier touches that the vehicle borrows from the Q60 coupe. There's a new steering wheel that has positions for the driver's thumbs and steering-wheel mounted gear-shifter paddles. A new leather-wrapped shift knob continues the double-stitched theme and is surround by a new piece of chrome trim.
While the Q50's powertrain has gone unchanged for 2018, INFINITI has revised the sedan's front and rear stabilizer bars, while adaptive shock absorbers, which the automaker calls Dynamic Digital Suspension, is available on the Q50 3.0t Sport as part of the Performance Package and is standard on the Red Sport 400 model.
Lastly, the Q50 lineup now features a new naming structure: Pure, Luxe, Sport, and Red Sport 400.
