The new 2008 Infiniti G37 Coupe makes its world debut at the New York motor show next month and reaches US Infiniti dealers in August.

The latest coupe is the first home for Nissan’s new 3.7-litre V6 engine with VVEL (for variable valve event and lift). Estimated to produce 330 horsepower and 270 lb-ft of torque, the VQ37VHR has approximately 35% unique parts compared with the new VQ35HR engine introduced in the G35 sedan last year.

The VVEL system combines hydraulic-controlled variable valve timing and electronically controlled variable valve lift on the intake side, helping to improve performance and response and also emissions and fuel efficiency. Overall vehicle fuel economy improvements are estimated to be nearly one mpg better than the G35 sedan and nearly two mpg better than the previous generation G35 coupe.

There will be a choice of an upgraded electronically controlled five-speed automatic transmission with optional paddle shifters or a significantly revised and more refined six-speed manual gearbox.

The G37 coupe’s enhanced platform and chassis also includes an optional 4-wheel active steer system (4WAS), which helps improve vehicle handling performance by adjusting both the front steering gear ratios and the rear suspension geometry according to steering input and vehicle speed. Braking and handling is targeted to be among the best in the luxury sport coupe class.

The new G Coupe also includes an extensive list of optional technological features – a touch screen navigation system with XM NavTraffic real-time traffic function, rear view monitor and an 11-speaker Infiniti Bose ‘studio on wheels’ audio system with three-way door speakers with 10-inch woofers and a 9.3-gigabyte hard drive.
