A new symmetric twin ram air intake system helps reduce airflow resistance by 18% and a new exhaust system design with equal length exhaust manifolds and reduced muffler exhaust pressure (25% less than the first generation G35) help improve engine breathing. Both are tuned to create authoritative harmonies, helping enhance driving pleasure.

The result of all these changes is an estimated 300-plus horsepower and a powerful torque curve (final horsepower and torque figures will be released at a later date), an exciting engine sound and expected improvements in emissions and fuel economy.

The new VQ engine design also includes a long list of advanced systems found on the previous design - including a continuously variable valve timing control system, a "noiseless" timing chain for quiet operation, an electronically controlled "drive-by-wire" throttle system, microfinished crank journals and cam lobes, and molybdenum coated lightweight pistons.

"There are a couple of unique features you notice about this new generation VQ engine - first, the great engine sound and the absence of the usual engine rough noises and vibrations," said Igo. "And secondly, the tuning strategy that is not strictly about standing-start acceleration, but a more refined balance of quick acceleration that builds continuously to the redline. It's a deepening pleasure that keeps getting better as you drive."

Infiniti G again offers a choice of 5-speed automatic transmission with manual shift mode or 6-speed manual transmission. The 5-speed automatic features Downshift Rev Matching, DS mode and ASC (Adaptive Shift Control) that allows for quicker shifts in sporty driving situations.

The 2007 Infiniti G's driving pleasure is also due in great measure to its second generation FM platform, similar to that used on the Infiniti M. The racing technology-inspired FM platform locates the engine behind the front axle in the "front mid-ship" position. The positioning of the engine provides an optimized front-to-rear-weight balance, while the combination of long wheelbase, manageable overall length and wider front and rear track (+0.7 inches front, + 0.9 inches rear) adds to Infiniti G35's overall handling stability.

The G's suspension is a 4-wheel independent design with lightweight aluminum components and front and rear stabilizer bars, designed to provide nimble and natural feeling handling, as well as a controlled, refined ride. The front suspension minimizes alignment changes through use of a lower wishbone and a long upper link. The rear design separates the shock absorbers and springs, locating the shock absorber inline with the wheel center to help reduce suspension friction and reduce the wind-up motion of the axle on acceleration.

Body stiffness has been enhanced through utilization of new structural pieces, including in the critical engine compartment and rear floor areas, and a 16% increase in the number of body spot welds.

The rear-wheel drive Infiniti G35 is also offered with a state-of-the-art "intelligent" all-wheel drive system. The G35x AWD model features Infiniti's ATTESA E-TS (Advanced Total Traction Engineering System for All Electronic Torque Split) all-wheel drive system is also utilized on the M35x and FX. The system utilizes an active torque distribution management system with an active center clutch designed for smooth starts and better traction and maneuverability on snowy roads than conventional all-wheel drive systems, and minimal compromise of rear-wheel drive performance characteristics on dry roads.

All 2007 G35s, rear-wheel and all-wheel drive, come with Vehicle Dynamic Control (VDC), helping to enhance vehicle stability under a variety of driving conditions, while Viscous Limited Slip Differential (VLSD) is standard on Sport models.

Infiniti G's braking system utilizes power-assisted 4-wheel vented disc brakes with 4-channel, 4-sensor Anti-lock Braking System (ABS), Electronic Brake force Distribution (EBD) and Brake Assist (BA).
