At the core of the 2009 Infiniti G37 Coupe’s stellar performance is its advanced 3.7-liter V6 engine with VVEL (for Variable Valve Event and Lift). Rated at 330 horsepower and 270 lb-ft of torque, the VQ37VHR is based on the award-winning VQ engine series, named one of the “Ten Best Engines” by Ward’s Auto World magazine for 14 consecutive years.

The G37 Coupe’s VVEL system combines hydraulic-controlled variable valve timing and electronically controlled variable valve lift on the intake side to help improve performance and response. The VVEL intake camshafts, featuring continuously variable lift control teamed with the Continuously Variable Valve Timing Control System (CVTCS), allow for a 7,500 rpm redline.

The engine also features increased cylinder block height (from the previous 3.5-liter design), ladder frame construction for greater rigidity, large crank journal and pin diameters, asymmetric piston skirts, twin knock sensors, an electronically controlled “drive-by-wire” throttle system, lightweight pistons, Iridium spark plugs and a symmetric twin air intake system. The specially tuned dual exhaust system features equal length exhaust manifolds and low muffler exhaust backpressure to help improve engine breathing. Both intake and exhaust enhance driving pleasure with their authentic performance notes.

“The G Coupe’s 3.7-liter V6 is a true powerhouse – becoming more enjoyable as you drive it,” said Igo. “This powerplant also features Infiniti’s trademark “Swell” acceleration – with special tuning that builds horsepower almost continually to the redline like a building wave.”

The G37 Coupe engine is backed by a choice of an electronically controlled 7-speed automatic transmission with manual mode, downshift rev matching, Drive Sport (DS) mode and Adaptive Shift Control (ASC) that allows for quicker shifts in sporty driving situations and available genuine magnesium paddle shifters; or a responsive, lightweight 6-speed manual transmission.
