The 2007 unveiling of the Infiniti G37 marked a significant leap forward in the luxury sport coupe segment. Building upon the esteemed G Coupe lineage, the 2007 Infiniti G37, designated as a 2008 model year vehicle, amplified every aspect that made its predecessors desirable, promising exhilarating performance, captivating aesthetics, and a modern, driver-centric interior. This new generation G Coupe wasn’t just an update; it was a comprehensive evolution, setting new benchmarks for luxury and sportiness in its class.
Powering the Future: The 3.7-Liter V6 Engine
At the heart of the 2007 Infiniti G37 lay a revolutionary engine: the 3.7-liter V6 with VVEL (Variable Valve Event and Lift). This marked the inaugural application of this advanced powerplant, designated VQ37VHR, in the Infiniti lineup. Producing a robust 330 horsepower and 270 lb-ft of torque, this engine represented a substantial upgrade in power compared to the previous G Coupe generations. While rooted in the celebrated VQ engine series, a recognized leader in automotive engineering for over a decade, the VQ37VHR boasted approximately 35% new and unique components compared to the VQ35HR engine found in the 2007 G35 Sedan.
The increased displacement from the prior 3.5-liter engine was just the beginning. The 2007 Infiniti G37’s VVEL system was a game-changer, employing hydraulically controlled variable valve timing and electronically controlled variable valve lift on the intake side. This sophisticated system optimized engine breathing across the RPM range, resulting in enhanced performance, quicker throttle response, and improved fuel efficiency and emissions. The VVEL intake camshafts, working in concert with the Continuously Variable Valve Timing Control System (CVTCS), allowed the engine to rev freely to an impressive 7,500 rpm redline, offering a truly sporty and engaging driving experience.
Further enhancing the engine’s performance and durability were features like an increased cylinder block height, a rigid ladder frame construction, larger crank journal and pin diameters, asymmetric piston skirts, twin knock sensors, an electronically controlled drive-by-wire throttle, lightweight molybdenum coated pistons, Iridium spark plugs, and a symmetric twin air intake system. A newly engineered dual exhaust system, meticulously tuned with equal length exhaust manifolds and low muffler exhaust backpressure, complemented the engine improvements, optimizing engine breathing and producing an authentic performance sound.
The 330 horsepower output of the 2007 Infiniti G37’s engine was not only a significant increase over previous models but was also achieved with anticipated improvements in fuel economy and reduced emissions, showcasing Infiniti’s commitment to both performance and environmental responsibility.
