Positioning in the Luxury Sport Sedan Segment
In the fiercely competitive luxury sport sedan market, the 2018 Infiniti Q50 carves its niche with a compelling blend of Japanese engineering and performance-oriented design. It goes head-to-head with established European rivals:
- Acura TLX: More conservative styling but often more affordable
- Audi A4: Benchmark for interior quality and tech
- BMW 3 Series: The gold standard for driving dynamics
- Mercedes-Benz C-Class: Leader in luxury appointments
What sets the Q50 apart is its combination of standard power (even base models get turbocharged engines), distinctive styling, and typically stronger value proposition than its German competitors when comparably equipped.

Exterior Design Evolution
The 2018 refresh brings subtle but meaningful changes to the Q50's exterior design, particularly for the performance-oriented variants:
Red Sport 400's Aggressive New Look
Infiniti designers sought to give the range-topping Red Sport 400 more visual differentiation from other trims. The result is a more extroverted design that some may find polarizing but performance enthusiasts will appreciate:
- Redesigned front bumper with more pronounced creases
- Narrower foglight housings that flow into contrasting lower trim
- More prominent rear diffuser with contrasting accents
- Unique 19-inch wheels (20-inch optional)
Across the Lineup
All Q50 models benefit from:
- Revised LED lighting signatures
- New wheel designs ranging from 17- to 20-inches

Interior Updates and Technology
While the cabin architecture remains largely unchanged, Infiniti made several meaningful upgrades to the Q50's interior for 2018:
Driver-Focused Enhancements
- New steering wheel design with smaller hub (borrowed from Q60 coupe)
- Improved seat bolstering in Sport and Red Sport models
- Quilted leather upholstery with contrast stitching in Red Sport
The Continued Dual-Screen Debate
The Q50 retains its controversial dual-screen infotainment system, which divides opinion among critics and owners alike:
| Upper Screen | Lower Screen |
|---|---|
| 8.0-inch display | 7.0-inch display |
| Navigation maps and primary information | Climate controls and secondary functions |
| Touchscreen capability | Primarily button-controlled |
While the system offers extensive functionality, some users find the division of controls between two screens and multiple input methods (touch, buttons, and rotary controller) unnecessarily complex compared to more streamlined systems from competitors.
