Exterior Design: Infiniti Styling on a German Frame
While the QX30's Mercedes-Benz GLA-Class roots are evident in its proportions (sharing the same 106.3-inch wheelbase), Infiniti designers successfully imbued the crossover with distinctive brand DNA:
- Signature Lighting: Wave-form LED headlights and taillights inspired by Infiniti's design language
- Dynamic Contours: Complex surface modeling with multiple character lines
- Forward-Kinking C-Pillars: A distinctive Infiniti styling cue
- Dual Grille Treatment: Pinched "double-arch" grille with mesh or waterfall designs
Trim variations included:
| Model | Ride Height | Wheels | Suspension |
|---|---|---|---|
| QX30 FWD | Standard | 18-inch alloys | Comfort-tuned |
| QX30 Sport | 0.6-inch lower | 19-inch alloys | Sport-tuned |
| QX30 AWD | 1.2-inch higher | 18-inch alloys | Raised for off-road |
Driving Dynamics: Improved Over Mercedes Origins
Infiniti engineers made significant improvements to the driving experience compared to the GLA-Class donor vehicle:
Powertrain Refinement
The shared 2.0L turbocharged M274 engine (co-developed by Nissan and Daimler) delivers 208 horsepower and 258 lb-ft of torque, but Infiniti's tuning yields better response:
- --SECOND CAR LIST HERE--
- More immediate throttle response than GLA250
- Smoother upshifts from the 7-speed dual-clutch transmission
- Faster downshifts when accelerating
Ride Comfort
Where the GLA-Class could feel harsh over rough pavement, the QX30 demonstrates:
- Better absorption of expansion joints
- More compliant damping on standard models
- Retained composure on Sport models despite firmer tuning

Handling Limitations
While comfortable, the QX30 isn't a sporty alternative:
- Noticeable body roll in corners
- Vague initial steering response
- Sport trim improves but doesn't transform dynamics
Interior: Premium Materials With Compromises
The QX30's cabin presents a mix of luxury and practicality challenges:

Material Quality
Upper trim levels feature:
- Genuine leather dashboard covering
- Soft-touch surfaces at eye level
- Aluminum-look trim accents
- Contrast stitching on seats and steering wheel
Space and Ergonomics
Significant compromises include:
- Front Seat Space: Limited headroom (37.3 inches) and narrow cabin
- Rear Seat Access: Short doors make entry/exit difficult despite decent legroom
- Visibility: Thick A-pillars, low windshield, small rear window
- Storage: Minimal interior cubbies and small center console
- --SECOND CONTENT ADVERTISEMENT HERE--
- Technology Interface
The mixed-origin controls present some inconsistencies:
- Infiniti's 7-inch touchscreen system (no Apple CarPlay/Android Auto)
- Mercedes-sourced instrument cluster display
- Borrowed Mercedes switchgear (window controls, key fob)
Practicality: Cargo and Storage
The QX30 offers modest utility for its class:
- Cargo Volume: 19.2 cubic feet behind rear seats
- Maximum Capacity: Approximately 43.6 cubic feet (est. based on GLA)
- Seat Flexibility: 60/40 split-folding rear seats standard
- Hidden Storage: Underfloor compartment in cargo area

Safety Features and Ratings
While NHTSA and IIHS hadn't rated the QX30 at launch, available safety tech included:
- Standard rearview camera
- Available blind spot monitoring
- Optional lane departure warning
- Forward collision warning with automatic braking
- 360-degree camera system (high trims)
Market Position and Competitors
The QX30 occupied a unique space in the luxury compact segment:

| Model | Starting Price (2017) | Powertrain | Key Differentiator |
|---|---|---|---|
| Infiniti QX30 | $30,945 | 208-hp 2.0T | Mercedes platform, distinctive styling |
| Mercedes GLA250 | $33,395 | 208-hp 2.0T | More premium badge, harsher ride |
| BMW X1 | $34,795 | 228-hp 2.0T | More spacious, better driving dynamics |
| Audi Q3 | $34,625 | 200-hp 2.0T | Quieter cabin, superior materials |
The QX30's value proposition centered on offering Mercedes engineering at a lower price point with more distinctive styling than the GLA-Class, though it couldn't match more spacious competitors like the BMW X1 in utility.

Long-Term Ownership Considerations
Prospective buyers should note:
- Reliability: Mixed reports due to complex Mercedes-derived components
- Maintenance Costs: Higher than non-luxury brands but competitive within segment
- Fuel Economy: EPA-rated at 24 mpg combined (21 city/30 highway for FWD)
- Depreciation: Steeper than some German rivals after 3-5 years
- --BOTTOM ADVERTISEMENT HERE--
- Conclusion: Who Should Consider the QX30?
The 2017 Infiniti QX30 made the most sense for:
- Style-Conscious Buyers: Seeking more distinctive looks than the GLA offered
- Urban Drivers: Who valued compact dimensions over interior space
- Value Seekers: Wanting Mercedes engineering at a lower price point
It proved less ideal for those needing
Spacious rear seats or easy access
- Engaging driving dynamics
- The latest tech features (missing smartphone integration)
Ultimately, the QX30 represented an intriguing but niche option in the luxury compact segment, blending Japanese and German automotive philosophies in a stylish, if compromised, package.
