For 2009, the Infiniti M35 receives a new, advanced DOHC 3.5-liter V6 rated at 303 horsepower and 262 lb-ft of torque – an increase of 28 horsepower over the previous 3.5-liter V6. The engine includes aluminum-alloy block and heads and electronically controlled “drive-by-wire” throttle system. Fuel economy improves to 17 mpg City/25 mpg Highway (from 16/23 mpg City/Highway) despite the increase in horsepower.

Two transmissions are offered with the V6 engine – a 5-speed automatic transmission with the all-wheel drive M35x and a new 7-speed automatic with the rear-wheel drive M35. Both transmissions feature a manual shift mode, Downshift Rev Matching and Drive Sport (DS) mode.

Every Infiniti M utilizes an enhanced next-generation FM (Front Mid-ship) platform also used on the G37 Sedan, G37 Coupe, EX35 and FX premium crossover SUV. The refined FM platform positions the engine behind the front axle. This positioning results in an optimized front-to-rear weight balance, which factors in weight transfer during key handling maneuvers.

The M suspension is an independent double-wishbone design in front and multi-link independent system in the rear, along with front and rear stabilizer bars. The Infiniti M’s large diameter wheels and tires are positioned out near the corners of the vehicle, helping to further enhance handling and driving excitement.

The 2009 M features split 5-spoke 18-inch aluminum-alloy wheels and P245/45VR18 tires. Unique split 5-spoke 19-inch aluminum-alloy wheels with titanium finish and aggressive P245/40WR19 low-profile tires are utilized with the Sport Package.

The M also utilizes standard 4-wheel power-assisted vented disc brakes with Anti-lock Braking System (ABS), Electronic Brake force Distribution (EBD) and Brake Assist (BA). The steering system is an electronically controlled vehicle-speed-sensing variable-assist power rack-and-pinion design.

Every Infiniti M features Infiniti’s advanced Vehicle Dynamic Control (VDC) with Traction Control System (TCS). VDC adjusts brake pressure and engine torque automatically in understeer, oversteer or slippery road surface situations, helping the driver keep the intended path.

For drivers seeking the enhanced all-climate performance of all-wheel drive, the M35x and M45x models feature the intelligent ATTESA E-TS™ (Advanced Total Traction Engineering System for All Electronic Torque Split) all-wheel drive system. It uses an advanced torque split control strategy that automatically transfers optimum torque to the wheels according to road and driving conditions.

The ATTESA E-TS™ system provides sports car-like handling and cornering capability due to optimum torque distribution between the front and rear wheels (front and rear 0:100 up to 50:50). ATTESA E-TS™ also provides high starting traction performance and smooth, stable acceleration, especially in snow-covered or off-road situations with a 50:50 torque split at standing start. Combined with the vehicle’s VDC system, each wheel receives the appropriate amount of torque when needed.

“The M45x and M35x are ideal for areas of the country that experience inclement weather conditions, as well as for drivers seeking the added handling and control benefits of all-wheel drive,” said Igo.

The handling and stability of the Infiniti M Sport Package-equipped models is further optimized by Infiniti’s Rear Active Steer system. Unlike passive rear steering systems, this design features precise, electronic motor-driven control. This system helps improve the M’s handling performance by adjusting the geometry of the rear suspension according to steering input and vehicle speed. The system’s electronic control unit calculates the desired vehicle dynamics from a series of sensors, including vehicle speed and steering angle, and directs the system actuator to change the rear geometry by moving both rear suspension lower links. The result is sports car-like agility, combined with luxury sedan stability and ride quality.
