The 2015 Infiniti Q50, often colloquially referred to as the 2015 G37 based on its predecessor's naming, represents a pivotal moment for the brand. This model year marked the debut of a new, sport-oriented direction, moving away from the previous G37's design language and embracing a more aggressive, modern aesthetic. The shift was not merely cosmetic; it signaled a fundamental change in how Infiniti wanted to position itself in the competitive luxury sports sedan segment, directly challenging the established hierarchies dominated by German manufacturers.
Design and Exterior Evolution
The most immediate observation regarding the 2015 model is its striking visual transformation. The design language, inspired by the Essence and Emerg-E concept cars, introduced a more pronounced and athletic stance. The front fascia is dominated by a larger, more intricate grille flanked by sharp, angular LED headlights that give the car a distinctly wider and more menacing presence. This aggressive styling was a deliberate move to capture attention and differentiate the Q50 from its more conservative predecessors.
Interior Refinements and Technology
Stepping inside reveals a cabin that is both luxurious and technologically advanced, a clear departure from the dated interfaces of earlier models. The dashboard features a clean, horizontal orientation, with premium materials like soft-touch plastics and available leather upholstery creating a sophisticated atmosphere. The centerpiece of the dashboard is the innovative InTouch infotainment system, which replaced the traditional rotary selector with a more modern, albeit initially controversial, touchpad controller. This change, along with the introduction of a dual-zone automatic climate control system, underscored the model's commitment to modern conveniences.
Performance and Handling Dynamics
Under the hood, the 2015 Q50 delivered on its sporty promises with a range of capable engines. The base model came equipped with a responsive 2.0-liter turbocharged four-cylinder, providing a balance of efficiency and power. However, the true heart of this generation lies in its performance variants. The Q50 Red Sport 400, with its 300-horsepower twin-turbo V6, offered exhilarating acceleration, while the legendary Q50 Hybrid combined a 2.5-liter Atkinson-cycle engine with an electric motor for a sophisticated and efficient power delivery. The available Intelligent All-Wheel Drive system further enhanced traction and stability, making the car confident in various weather conditions.
Suspension and Driving Dynamics
Infiniti's engineers paid significant attention to the chassis, resulting in a driving experience that was both engaging and comfortable. The standard adaptive suspension provided a firm yet controlled ride, effectively damping road imperfections while maintaining composure during spirited driving. For enthusiasts, the optional Performance Direct Injection (PDI) suspension took this a step further, allowing drivers to adjust damping rates in real-time. This focus on dynamic handling was a key differentiator, allowing the Q50 to feel nimble and precise, a characteristic often missing in its luxury rivals.
Safety and Contemporary Features
Beyond performance, the 2015 model year placed a strong emphasis on safety, integrating advanced driver-assistance systems as part of its value proposition. Features like Intelligent Cruise Control with Low Speed Follow, Emergency Brake Assist, and Lane Departure Prevention were becoming standard or available options, reflecting the industry's move towards semi-autonomous driving capabilities. The Q50's structure was engineered to meet strict safety standards, providing a secure environment for occupants without compromising the car's dynamic integrity.
