G37 Engine

Specification

The Infiniti G37 Engine comes equipped with a VQ37VHR 3.7-liter naturally aspirated V6 engine, offering a DOHC, 24-valve aluminum-block powerplant engineered for both performance and durability. In standard G37 models, it delivers approximately 328 horsepower and 270 lb-ft of torque, providing strong acceleration and a smooth, linear power band, while the Infiniti Performance Line (IPL) variant raises output to around 348 horsepower for a more aggressive driving experience. The engine features a high 7,500-RPM redline, advanced valve control technology for improved throttle response, and a premium fuel requirement to maximize performance and efficiency.

The G37 engine has a high 11.0:1 compression ratio, contributing to its responsive nature and linear power delivery. Power is transferred through either a 6-speed manual transmission for driving enthusiasts or a 7-speed automatic transmission with manual shift mode for convenience and smooth shifting. The G37 is primarily rear-wheel drive, with an optional all-wheel-drive system available for enhanced traction in varying road conditions. Known for its durability and sporty character, the VQ37VHR engine combines reliability, refined engineering, and engaging performance, making the Infiniti G37 a well-balanced luxury sports sedan and coupe. This proven VQ platform evolved into the next generation Q50 engine, which built upon these solid foundations.
