The 2018 Q50 represents a pivotal moment for Infiniti, marking the transition to a new era of design and engineering. This specific model year refined the brand's signature performance sedan, balancing aggressive aesthetics with a focus on modern technology and comfort. Understanding the 2018 Q50 specs provides insight into how the brand positioned itself against rivals from BMW and Mercedes-Benz during that competitive segment.
Exterior Design and Dimensions
Visually, the 2018 Q50 showcased a more mature and sophisticated stance compared to its initial sporty iterations. The front fascia featured a larger, more prominent grille that stretched horizontally, integrating slimmer LED headlights. The signature LED daytime running lights, known as the "Light Blade," retained their sleek design but were slightly reshaped for enhanced clarity. The overall silhouette remained low and athletic, with a pronounced shoulder line that flowed into 19-inch alloy wheels, contributing to a sense of stability and premium presence.
Performance and Drivetrain Options
Under the hood, the 2018 Q50 offered a compelling range of powertrains to suit different driving preferences. The base model came equipped with a 2.0-liter turbocharged inline-four engine producing 208 horsepower, adequate for daily driving and highway merging. For those seeking more excitement, the Q50 Red Sport 400 was the performance highlight, utilizing a 3.0-liter twin-turbocharged V6 that generated an impressive 400 horsepower. This variant delivered sharp throttle response and a thrilling exhaust note, cementing the Q50's sporty credentials.
Interior Comfort and Technology
Inside, the 2018 Q50 embraced a driver-centric cockpit, featuring soft-touch materials and a clean, minimalist dashboard. The available Infiniti InTouch touch-screen interface controlled navigation, audio, and vehicle settings with reasonable responsiveness. Premium appointments included heated front and rear seats, a power-adjustable front driver's seat with memory, and a panoramic moonroof that enhanced the sense of openness. The cabin effectively muffled road and wind noise, creating a serene environment for passengers during long journeys.
Safety and Driver Assistance
Safety was a strong point for the 2018 Q50, earning a Top Safety Pick+ rating from the Insurance Institute for Highway Safety (IIHS). The suite of available driver assistance technologies, branded as Direct Adaptive Steering, proved to be a standout feature.

Additionally, standard features included lane departure warning, blind-spot intervention, and forward collision warning with automatic emergency braking.
