Powertrain & Engine Architecture
The heart of the EX35 is the VQ35HR 3.5-liter V6 engine. This engine, a member of Nissan’s highly regarded VQ family, is known for its smooth power delivery and reliability. The “HR” designation signifies a high revolution version, featuring a revised cylinder head, variable valve timing (VVT) on both intake and exhaust valves (Continuously Variable Valve Timing Control System – CVTCS), and improved intake and exhaust systems. The engine produces 295 horsepower at 6,800 rpm and 269 lb-ft of torque at 4,800 rpm. Fuel is delivered via multi-port fuel injection. The engine is longitudinally mounted, contributing to the EX35’s balanced handling characteristics. The EX35 utilized a five-speed automatic transmission, which was tuned for smooth shifts and responsive acceleration. While not the most advanced transmission available at the time, it was well-matched to the engine’s powerband.
Driving Characteristics
The EX35 3.5i with the automatic transmission delivers a comfortable and capable driving experience. Acceleration from 0-60 mph takes approximately 6.6 seconds, making it reasonably quick for its class. The automatic transmission provides smooth gear changes, although it can sometimes feel hesitant during quick downshifts. The all-wheel-drive system provides excellent traction in various weather conditions. Compared to the available manual transmission, the automatic sacrifices some driver engagement but offers greater convenience. The EX35 doesn’t possess the outright sportiness of some competitors, but its well-tuned suspension and responsive steering make it enjoyable to drive on winding roads. The gear ratios are optimized for everyday driving, prioritizing fuel efficiency and comfortable cruising over aggressive acceleration.
Equipment & Trim Levels
The EX35 came standard with a generous array of features, including leather upholstery, power-adjustable front seats, a Bose premium sound system, a navigation system, and automatic climate control. Available options included a panoramic sunroof, adaptive cruise control, lane departure warning, and a rear-view camera. The EX35 was offered in a single, well-equipped trim level, with most customization coming through optional packages. Interior materials were generally high quality, reflecting the vehicle’s luxury positioning. The dashboard layout was driver-focused, with intuitive controls and a clear instrument cluster.
Chassis & Braking
The EX35 features a fully independent suspension system, with MacPherson struts in the front and a multi-link setup in the rear. This configuration provides a comfortable ride while maintaining good handling characteristics. Brakes are ventilated discs on all four wheels, providing ample stopping power. An Anti-lock Braking System (ABS) is standard. The EX35’s chassis is relatively stiff, contributing to its overall stability and responsiveness. Stabilizer bars are present at both the front and rear to reduce body roll during cornering.
Market Reception & Comparison
The Infiniti EX35 was generally well-received by automotive critics. It was praised for its stylish design, comfortable interior, and strong performance. However, some reviewers noted that the fuel economy was not particularly impressive for its class. Compared to rivals like the BMW X3 and Audi Q5, the EX35 offered a more affordable price point and a more generous standard features list. The 19.1 US mpg combined fuel economy was typical for a V6-powered crossover of that era, but lagged behind some of the more fuel-efficient four-cylinder options. Reliability was generally good, with few major issues reported.
Legacy
The Infiniti EX35, while discontinued in 2013, remains a popular choice in the used car market. The VQ35HR engine is known for its durability and longevity, and the EX35’s overall build quality is solid. Maintenance costs are generally reasonable, although routine servicing should be performed to ensure optimal performance. The EX35’s blend of luxury, performance, and technology continues to appeal to buyers seeking a versatile and reliable crossover. Its influence can be seen in subsequent Infiniti models, which have continued to emphasize sporty driving dynamics and premium features.
