2017 INFINITI Q50 Sedan

2018 Infiniti Q50: The Endless Updates Continue

Launched for 2014, Infiniti’s Q50 sedan already has received a number of major updates. Changes to its controversial steer-by-wire system came first; then a comprehensive powertrain overhaul for 2016 added a four-cylinder option and a new twin-turbo V-6. For the 2018 model year, the Q50 is getting its first visual updates inside and out.

The Q50’s front end is only slghtly different than before, with new lower air intakes, a more three-dimensional look for the grille, and a reshaped bumper. The rear-end makeover is similarly subtle, with more modern-looking LED taillights and a reshaped bumper. We don’t quite see the increased differentiation that Infiniti claims between the standard Q50 and the more performance-oriented Red Sport 400, but the refresh doesn’t mar the sedan’s attractive looks, either.

Inside, a new steering wheel is borrowed from the Q60 coupe, and Infiniti says it’s introducing nicer faux-leather materials for the dashboard along with new wood trim options. We’re surprised that the refresh doesn’t include an update for Infiniti’s infotainment software, which is a weak point due to its slow operation and dated graphics.

Four powertrain setups continue to be available—a 208-hp turbocharged 2.0-liter inline-four, twin-turbocharged 3.0-liter V-6s in 300-hp and 400-hp strengths, and a hybrid. The trim levels, however, have been reorganized. Pure and Luxe trims replace the existing base and Premium models, while the Sport and Red Sport 400 models stick around. We should learn details about pricing for these models by the time the updated Q50 hits dealerships sometime this summer.

Exterior Design

The Q50 is one slinky sedan, set to make anyone in a coupe seem dull. The 208-hp turbo four lacks power to back up those looks; consider the twin-turbo V-6 with 300 hp, or 400 hp in the Red Sport. Rear-drive is standard; all-wheel drive is optional. A hybrid rates at 34-mpg highway; rear-drive is standard and all-wheel drive is optional. Infotainment features apps for email, calendar syncing, and concierge services. Available safety tech includes lane assist and backup collision intervention.

Ready To Empower Your Drive

The 2017 Q50 3.0t Signature Edition offers a unique combination of style and value, ready to empower your drive.
