2011 Infiniti M35h

We don’t talk about Infiniti all too often here on TopSpeed, but lately they have been part of our news due to their new Infiniti Performance Line (IPL) and the fact that they will be debuting two new M-based models at the Pebble Beach Concours. Now we get to talk about them for a different reason. Infiniti is now ready to introduce the technological advancements in the M35h that they have been discussing for quite some time: world-first steering and braking technologies. These technologies will be ready to roll when the car goes on sale in the USA and Europe in 2011.

The Infiniti M35H will be powered by a hybrid drive system that combines a naturally-aspirated 3.5-liter V6 engine with a 68 HP electric motor mated to a 7-speed Adaptive Shift Control (ASC) automatic transmission. The motor directly operates the brakes using a system called the Electric Driven Intelligent Brake. This system works by allowing the motor to charge the battery when the driver applies the brake. The steering is also unique in the M35h because it is part hydraulic and part electric. The electric portion kicks in when the wheel is turned which boosts efficiency. Both of these technologies may be found in all future Infiniti Direct Response Hybrid vehicles due to their simplicity and effectiveness.

Update 02/07/2011: Infiniti has announced today the official official EPA (Environmental Protection Agency) fuel economy figures for the M35h. The V6 hybrid sedan has a fuel economy is 27 mpg City, 32 mpg Highway, with Combined fuel economy rated at 29 mpg.

UPDATE 01/24/2012: Nissan’s luxury division has released a video of their new M35h sedan taking on the equally irrepressible 2012 Porsche Panamera S Hybrid.

Not one to back down from a German challenge for full-on hybrid supremacy, the M35h and the Panamera S Hybrid engaged in a quarter-mile drag race - with surprising results.

Not only did the 360-horsepower M35h complete its time in just 13.4 seconds - impressive for a hybrid! - but it also managed to spank the Panamera S Hybrid by a good second. On top of that, the time is also a marked improvement from their previous record time of 13.9031 seconds , eclipsing the Guinness World Record by a tidy half-a-second. Check out the video to watch the Infiniti M35h show up the Porsche Panamera S Hybrid.

UPDATE 02/13/12: Infiniti has released a behind-the-scenes look at all the preparation work, setup, and equipment involved in filming the video showing the M35h’s record-breaking acceleration time. It sure looked like it took a lot of complicated equipment just to shoot a video on how the M35h became the fastest accelerating hybrid in the world.

Press release after the jump.

The “driver’s hybrid” from Infiniti, the M35h, will introduce world-first steering and braking technologies when it goes on sale in the USA and Europe in 2011. The debut systems have been designed to deliver both environmental benefits and enhanced driving feel, reinforcing strengths already central to the Infiniti M35h with its innovative one motor/two clutch system.

Like the drivetrain, which marries a charismatic V6 petrol engine with 50 kW (68 PS) electric motor built in to the 7-speed automatic transmission, simplicity was a key tenet in the development of the steering and brakes of the high performance luxury sedan.

The steering of the Infiniti M35h 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 – while the motor cuts in only when the wheel is turned, further boosting efficiency. The system is smaller 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, but at the same time contributing to the lower carbon footprint of the M35h, low CO2 champion of Infiniti’s all-new M Line sedan line-up.

The engineers looked to the hybrid system itself for the solution. What they came up with – a way to use the vehicle’s 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. Because of its simple structure, in which the motor directly operates the brake cylinders, the Electric Driven Intelligent Brake system has the potential to be a key part of all future Infiniti Direct Response Hybrid vehicles.

The simplicity of these elegant mechanical solutions, with their emphasis on more compactness, lighter weight and fewer parts, is made possible by advanced computerized control.

Another benefit of both the new steering and braking systems is that they work with the innovative drivetrain to enhance the driving experience rather than dilute it in the manner of some hybrid vehicles. Designed to be fast and responsive with a strong sporting bias to the rear-wheel drive handling, the Infiniti M35h aims to deliver an exhilarating drive in all situations.

Central to this is its one motor/two clutch system. The first clutch is installed between the naturally-aspirated 3.5-litre V6 and the electric motor, which is embedded within the automatic transmission. The electronically controlled clutch allows the full decoupling of the V6 when the car is in electric drive and power regeneration modes. Decoupling the V6 reduces mechanical drag and boosts the efficiency of the electric motor.

Aided by an exceptionally fast charge/discharge response from the lithium-ion battery pack, the result is a hybrid that’s electrically powered for more of the time, and at higher speeds, than conventional hybrids.

Yet when the driver demands it the Infiniti M35h responds like a true high performance machine, offering the linear acceleration and unsullied rear-drive handling of a true Infiniti ­– complete with all the charisma of one of the great V6 petrol engines. Like the 7-speed Adaptive Shift Control (ASC) automatic transmission that blips the throttle on downchanges, the new braking and steering technologies are integral to the M35h’s positioning as the hybrid to please the most demanding of drivers.

Infiniti’s first hybrid, the M35h is the low CO2 star of the all-new M Line which also includes petrol and diesel models and which is the first M ever to be sold in all of Infiniti’s 34 world markets.

Among the Infiniti M’s many other claims to fame are the world-first Blind Spot Intervention (BSI), state-of-the-art Forest Air climate control and Active Noise Control, while comfort and luxury are taken care of with double-piston dampers and the availability of semi-aniline leather in the spacious cabin.

M35h sales start in spring 2011, depending on market.

Nowadays, most of the company cars are now creating lots of hybrid cars, and I must say that this one is really awesome, it is simple but very appealing.

What I like here is its plain simple styled car. Though it made of a more technological and advanced it naturally let still poured out its luxury type.

Looking by this M35h seems that it is not a hybrid car, but I must say that I love the simplicity that Infiniti M35h had but I found it very appealing.

I’m impressed with the fact the it is a hybrid car. Today’s most of the company cars are now creating lots of hybrid cars and I must say that this one is really awesome, it is simple but very appealing.

Wow! I’m impressed for the two set of wheels of Infiniti M35h its actually have a wheel with a boost efficiency, I’m sure it will kick your out in the road.

If the NISMO is behind all of this, then expect the un-expected from NISMO.I wonder what will the cost of M35h with torque is 276 pound-feet at 5,200 rpm?

I can’t believe that Nissan and Mercedes Benz come up with this Idea.

The noise is loudest at start-up to give pedestrians and other road users a clear indication that the vehicle is moving off, and cuts out as the vehicle reaches 30km/h. Nissan and Infiniti engineers say the road noise above that speed is loud enough for the vehicle to be detected.

Yet when the driver demands it the Infiniti M35h responds like a truehigh performance machine, offering the linear acceleration and unsullied rear-drive handling of a true Infiniti ­– complete with all the charisma of one of the great V6 petrol engines.

This one is actually a nice take by Infiniti. If this one gets a foothold of the market, it will certainly give Infiniti their needed boost.

The only part that I love about this car is the adaptive shift control.
