The INFINITI EX series redefined compact luxury crossovers with its sporty wagon-like design, powerful V6 powertrains, and driver-focused dynamics. Launched as the EX35 in 2008, it evolved through the EX37 phase and transitioned to the QX50, blending sedan agility with SUV versatility.
Origins and Model Evolution
The INFINITI EX emerged in 2008 as a near-luxury compact crossover SUV, essentially a raised version of the acclaimed G37 sedan. This shared platform delivered exceptional handling and balance, distinguishing it from typical front-wheel-drive competitors.
- 2008-2012: EX35 era with 3.5L V6 and initial 5-speed automatic.
- 2011 refresh: Upgraded to 7-speed automatic for better efficiency.
- 2013: Renamed EX37 with 3.7L V6 boost.
- 2014 onward: Rebadged as QX50, maintaining core traits.
Production spanned from 2008 to 2017 in the U.S., competing against BMW X3, Acura RDX, and Mercedes-Benz GLK-Class.
Powertrain and Performance Highlights
At the heart of every EX model was a robust V6 engine tuned for spirited performance. The initial EX35 featured a 3.5-liter V6 producing 297 horsepower and 253 lb-ft of torque, paired initially with a 5-speed automatic and later a smoother 7-speed unit.
| Model Year | Engine | Horsepower | Transmission | 0-60 mph |

| 2008-2012 EX35 | 3.5L V6 | 297 hp | 5/7-speed Auto | ~6.2 sec |
| 2013 EX37 | 3.7L V6 | 325 hp (est.) | 7-speed Auto | ~6.0 sec |
Rear-wheel drive was standard, with all-wheel drive optional, enabling precise handling and quick acceleration. EPA ratings hovered at 16-20 mpg combined, prioritizing thrill over ultimate efficiency.
Design and Exterior Styling
The EX’s low-slung stance and sleek lines evoked a premium wagon more than a traditional SUV. Its dramatic bodywork housed 18-inch alloy wheels standard, with 19-inch options on higher trims. Available in multiple paint colors like Arctic Blue post-2011, it projected sophistication and athleticism.
Dimensions emphasized compactness: roughly 182 inches long with a wheelbase supporting five passengers comfortably. This setup provided agile maneuverability in urban settings while offering SUV-like visibility.
Interior Comfort and Luxury Features
Inside, the EX prioritized driver engagement with an 8-way power driver’s seat featuring lumbar support and a 4-way passenger seat. Leather upholstery, dual-zone climate control, and genuine wood trim elevated the cabin.
- Standard amenities: Satellite radio, USB port, 18-inch wheels.
- Journey trim extras: Moonroof, heated seats, Bluetooth.
- Premium audio: Bose system with upgraded speakers post-refresh.
The intimate five-seat layout focused on front-row pleasure, with technologies like Around View Monitor and Bose audio enhancing daily drives.
Safety and Technology Innovations
Safety was comprehensive, including four-wheel anti-lock brakes, stability control, and multiple airbags. Optional advanced aids like Around View Monitor (360-degree cameras), blind-spot warning, and Lane Departure Prevention set benchmarks for the era.
Infotainment evolved with USB connectivity, Bluetooth hands-free, and optional navigation, making the EX a tech-forward choice in luxury crossovers.
