From Infiniti press: 2008 Infiniti M Receives Major Upgrades, Including First Available Production Lane Departure Prevention System
Just two years after its highly successful introduction, the Infiniti M receives major upgrades for 2008 that include the first-ever availability of Infiniti’s intelligent ATTESA™ E-TS all-wheel drive system on the 4.5-liter V8-powered M45. The new model, designated M45x, joins the M35x to provide buyers with two choices in all-climate AWD performance.
The M45 continues to offer a powerful DOHC 4.5-liter V8, shared with the premium FX45. It is rated at 325 horsepower and 336 lb-ft of torque. The engine design includes titanium valves, modular cylinder heads, microfinished crankshaft, lightweight pistons and super-silent single stage cam drive chain to help optimize performance. In addition, the VK45DE is outfitted with a variable length air induction system and Continuously Variable Valve Timing Control System (CVTCS) to enhance the engine’s power delivery and operation efficiency.
The M35 utilizes an advanced DOHC 3.5-liter V6 rated at 275 horsepower and 268 lb-ft of torque. The V6 is part of the award-winning VQ engine series also found in the G35 and FX35, and includes aluminum-alloy block and heads and electronically controlled “drive-by-wire” throttle system. Both engines are mated to a standard 5-speed automatic transmission with performance shifter and manual shift mode with downshift rev matching.
Every Infiniti M utilizes an enhanced next-generation FM (Front Mid-ship) platform also used on the G35 Sedan, G37 Coupe and FX premium crossover SUV.
