Infiniti Releases More Details on the M35 Hybrid

Infiniti has released has more technical details about its first hybrid, the Infiniti M35 Hybrid, before car’s unveiling at the 2010 Paris Motor Show next week.

The body style for the M35 Hybrid is the same as the new generation Infiniti M sedan, which was introduced earlier this year in Geneva.

As the M35h name suggests, the car will use a 3.5-liter V-6 gasoline engine, which delivers 225 kW (306 PS), backed up by 350 Nm of torque at 5000 rpm. The electric motor is rated at 50 kW (68 PS) and provides high torque from zero rpm, peaking at 270 Nm at just 1000 rpm, ensuring dynamic performance from standstill. This combination makes the M35 Hybrid the fastest accelerating car in Infiniti Europe’s range.

Both gasoline V6 and electric motor deliver their power to the rear wheels via a 7-speed automatic transmission. An electric motor sits directly behind the engine on the prop shaft. A battery pack made from laminated lithium-ion cells powers the motor and gets recharged during braking and deceleration.

Exact figures are still to be confirmed, but Infiniti says the M35h is expected to hit 62mph (100km/h) in less than 5.9 seconds, average 38.6mpg UK (7.3 L/100km or 32.2mpg US) and emit less than 170g/km CO2.

The Infiniti M35 Hybrid will employ Infiniti's latest cabin tech and driver assistance features, which are considerable.

The M35h is equipped with world-first steering and braking technologies which have been designed to deliver both environmental benefits and enhanced driving feel, reinforcing strengths already central to the car.

The steering is an electro-hydraulic system with “on-demand” assistance. It offers the advantages of both types of steering – the natural and smooth feel of hydraulic power steering and the improved fuel efficiency of an electric system. The motor cuts in only when the wheel is turned, further boosting efficiency. The system is more compact and lighter than traditional power steering set-ups, a feat achieved by integrating multiple parts.

The brakes are similarly designed primarily to suit sports sedan buyers’ needs while at the same time contributing to the M35h’s lower carbon footprint. The engineers looked to the hybrid system itself for the solution. What they came up with – a way to use the electric drive motor to operate the brake cylinders – represents another world-first innovation for the Japanese brand.

The system is called Electric Driven Intelligent Brake. When the driver steps on the brake pedal, the necessary braking force is maintained while the hydraulic pressure of the friction brake is controlled to help maximize the energy regeneration of the hybrid motor.

Infiniti M35 Hybrid was first unveiled
earlier this year in Geneva. It will make it’s North American debut in November at the 2010 LA Auto Show.

In Europe, the Infiniti M35h will go on sale alongside the previously announced V6 gasoline- and diesel-engined models, the M37 and M30d. It will be available with a choice of base and GT trims, and first deliveries are expected to start next spring.
