2012 Infiniti M35 Hybrid breaks cover

Article by Christian Andrei, on August 26, 2010

Premium carmaker Infiniti will start sales of the new hybrid vehicle as part of its new line of Infiniti M luxury performance sedans. Infiniti will commence selling its 2011 Infiniti M vehicles in spring 2010, and the 2012 Infiniti M35 hybrid a year later.

Interestingly, the 2012 Infiniti M35 hybrid is Infiniti's first hybrid since the carmaker was established two decades ago. Moreover, the 2012 Infiniti M35 hybrid holds the record as its cleanest and most efficient vehicle until now.

This hybrid was inspired by the Infiniti Essence concept car, which showed its potential as a high performance vehicle with low emissions. Building on the concept, the new M35 Hybrid has been designed and engineered to provide more driving experience on the road.

Astonishingly, the M35 Hybrid was derived from the all-new M, which features styling cues from the Essence concept. While the M35 Hybrid is essentially a high performance luxury sedan, it features the fuel economy and carbon dioxide emissions of a smaller car.

This rear-wheel-drive hybrid is powered by a naturally aspirated 3.5-liter V6 and the electric motor. It features Infiniti's hybrid system, a single electric motor/twin clutch arrangement.

The first clutch is installed between the V6 and the electric motor. This arrangement has all the components act on a single prop shaft to the rear differential, thereby providing the necessary linear performance and direct responses, resulting to dependable driving feel under any condition.

When the driver needs to accelerate, the system's electric motor could dynamically boost the V6 engine during "power assist" mode. This motor could also serve as a generator that charges the battery in a conventional manner.

Interestingly, the motor could recover energy during deceleration and braking. In particular conditions, the M35 Hybrid can go full electric, although Infiniti has yet to disclose the range and performance numbers when in this mode.

Infiniti will later announce the transmission system that will be employed on the M35 Hybrid. On the other hand, the premium carmaker has provided the M35 Hybrid with an array of new technologies, like a "laminated" lithium-ion (Li-ion) battery pack that provides twice the power while having the same size as conventional batteries but offers twice the power.

When laminated, the battery pack offers better cooling performance, with manganese positive electrodes improving its temperature stability. Thus, the laminated Li-ion battery pack offers outstanding reliability.

Infiniti will be selling the M35 Hybrid – along with the conventional powered 2011 M vehicles -- across all of its markets around the world, pegged at around 33 countries. Amazingly, all new-generation Infiniti M models are more powerful, more fuel efficient and emit less carbon dioxide than their predecessors.

Infiniti Confirms M35 Hybrid Production

Infiniti today confirmed that its first production hybrid vehicle will be part of the recently announced line of 2011 Infiniti M luxury performance sedans, which are scheduled to go on sale in spring 2010 at Infiniti dealers nationwide. The Infiniti M35 hybrid is expected to arrive about 12 months later as a 2012 model. It is Infiniti's first hybrid in its 20-year existence, as well as the cleanest and most economical car in Infiniti's history. Realizing the high performance/low emissions promise of the recent Infiniti Essence concept car, the M35 Hybrid has been designed and engineered to add to, not take away from, the driving experience, a key part of any Infiniti's appeal. The M35 Hybrid is based on the all-new M, which itself picks up styling cues from Essence, the show-stopper that made its debut at the Geneva Auto Show early in 2009.

The M35 Hybrid maintains a high performance luxury sedan profile, overlaying it with the fuel economy and CO2 emissions of a smaller car, while delivering driving flair to please any enthusiasts' complete with charismatic V6 and rear-wheel drive handling. Infiniti's hybrid system, developed solely within Infiniti's parent group, is a single electric motor/twin clutch arrangement. Innovatively, the first clutch is installed between the naturally aspirated 3.5-liter V6 and the electric motor. The result of this configuration, where all components act on a single prop shaft to the rear differential, is a consistent driving feel under all conditions with linear performance and the "direct responses" that the engineers sought. The electric motor acts as both propulsion unit, boosting the V6 in "power assist" mode when maximum acceleration is required, and also as a generator. Along with charging the battery in the normal way, the motor recovers energy otherwise lost during deceleration and braking.

The M Hybrid can also run solely on its electric motor in certain driving conditions, furthering fuel efficiency and optimizing energy usage across the widest possible range of driving conditions. Details of driving range, performance and transmission will be released later. As expected of Infiniti, several new technologies are introduced in the new M35 Hybrid, including a "laminated" lithium-ion (Li-ion) battery pack that is the same size as conventional batteries but offers twice the power. Lamination enhances the pack's cooling performance, while temperature stability is further improved by the use of manganese positive electrodes. An end result of this is exceptional battery reliability.

The M35 Hybrid joins conventional engine-equipped 2011 M versions' including a new high-performance diesel V6 for Western Europe as the first Ms to be sold across all of Infiniti‚ world markets, currently 33 countries. All of the new-generation Infiniti M models are on target to beat their predecessors on fuel consumption and emissions despite across-the-board performance improvements thanks to a range of efficiency-enhancing measures.
