The 2018 Q50 represents a pivotal moment for Infiniti's flagship sedan, blending sporty DNA with luxurious appointments. This model year specifically refers to the updates and configurations available during the 2018 model year cycle, which often bridges the gap between the outgoing generation and its successor. Buyers looking at a 2018 Q50 were met with a mature platform that had been refined over several years, offering a compelling mix of performance, technology, and comfort.
Design and Exterior Refinements
Visually, the 2018 Q50 maintained the sleek, aerodynamic profile that defined its predecessor, yet subtle changes signaled its updated status. The front fascia featured a more sculpted grille, often finished in a darker metallic hue, which framed the signature LED headlights more aggressively. These lighting elements not only enhanced the car's appearance but significantly improved visibility and safety during night driving.
Side profile changes were more nuanced, with updated alloy wheel designs adding a touch of sophistication. The standard 19-inch wheels on higher trims provided a muscular stance, while optional packages introduced different finishes and spoke patterns. The rear design continued the elegant lines, culminating in a full-width LED taillight bar that became a modern Infiniti signature, improving the car's presence on the highway.
Performance and Drivetrain Options
Under the hood, the 2018 Q50 offered a range of powertrains to suit different driving preferences, staying true to the sport-sedan ethos. The base model came equipped with a responsive 2.0-liter turbocharged four-cylinder engine, delivering adequate power for daily driving and efficient fuel economy. For those seeking more vigor, the 3.7-liter V6 remained the heart of the lineup, producing robust horsepower and smooth power delivery.
2.0L Turbo I4: Approximately 208 horsepower
3.7L V6: Approximately 328 horsepower
Available 7-speed automatic transmission with paddle shifters
The sport-tuned suspension, particularly on models equipped with the Performance or Red Sport trims, provided a firm yet controlled ride. This setup, combined with the available Intelligent All-Wheel Drive system, ensured confident handling in various weather conditions and road surfaces. Drivers could choose between standard rear-wheel drive for efficiency or the more engaging all-wheel drive for traction.
Interior Comfort and Technology
Inside, the 2018 Q50 continued to impress with its cabin ambiance. Premium materials such as soft-touch plastics, genuine leather, and brushed metal accents were used extensively, creating an atmosphere of refined comfort. The seats, bolstered for lateral support, offered excellent comfort on long journeys, with memory functions available on higher trims to accommodate multiple drivers.
The infotainment system was a focal point, centered around a high-resolution touchscreen that integrated navigation, audio, and vehicle settings. Apple CarPlay and Android Auto compatibility were often included, allowing seamless smartphone integration. The advanced safety suite, available as part of the Confidence Safety Package, added features like adaptive cruise control and lane departure warning, enhancing both safety and driving ease.
Trim Levels and Market Positioning
Infiniti structured the 2018 Q50 lineup into several distinct trim levels, each catering to specific buyer needs. The Pure offered the essential features, serving as an accessible entry point. The Sport and Premium trims added more aggressive styling and enhanced technology, respectively. The pinnacle of the range, the Red Sport, featured a more aggressive exterior, sport-tuned components, and a powerful twin-turbo V6 engine.
