2011 Infiniti Cars M35h Sports Sedan The "Driver's" Hybrid

The “driver’s hybrid” from Infiniti, the M35h sports sedan, will introduce world-first steering and braking technologies when it goes on sale in the USA and Europe in 2011. The company calls the M35h a "driver's hybrid," with innovations in both steering and braking technologies designed to blend fuel efficiency with driving feel. As the first in-house hybrid from Nissan/Infiniti, the M35h is pretty unassuming. Indeed, although the test cars we drove in Japan were covered with decals advertising their gasoline-electricness, small “hybrid” badges on the production models’ front fenders will be the biggest powertrain giveaway once the cars arrive stateside next spring.

The Infiniti’s single electric motor is located between the engine and automatic transmission, in place of a conventional torque converter. The 67-hp motor is connected to the crankshaft via a wet-plate clutch. This allows the M to use its 1.3-kWh, 340-volt lithium-ion battery pack for electric-only propulsion at speeds up to about 60 mph as long as the driver keeps throttle application below 20 percent.

The 2011 Infiniti sports sedan M35h uses a 3.5-litre petrol V6 and a 68 PS (50 kW) electric motor for propulsion while power is put to the ground via a seven-speed automatic gearbox. 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 sports sedan line-up.

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.

Infiniti’s sports sedan 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.

Extensive details regarding these two innovations are available in the press release and Inifiniti said it will sell the M35h sports sedan on all of their 34 world markets. M35h sports sedan sales start in spring 2011, depending on market.

2011 Infiniti Cars IPL G Coupe With New Performance

Nissan's luxury division has unveiled the 2011 Infiniti IPL G Coupe, with new performance coupe, and for those that want to see the car in the flesh should attend the 60th edition Pebble Beach Concours d'Elegance. The first production vehicle from this group, the 348-horsepower 2011 Infiniti Performance Line G Coupe. It joins the Infiniti line of performance luxury vehicles at Infiniti retailers nationwide in December. Infiniti is heading down the road already strafed by the likes of BMW's M division, Mercedes-Benz' AMG sub-brand, and Audi's S and RS offspring, with a new performance badge dubbed IPL.

The IPL G Coupe's enhanced performance comes from the synergetic effects of three technology areas – engine tuning, dynamic tuning and sound quality/acceleration feel tuning. Engine performance modifications were selected not only for increased horsepower and torque levels, but also for acceleration feel and exhaust sound without compromising fuel economy or noise standards.

The IPL G Coupe's advanced VQ37HR 3.7-liter V6 engine management system has been recalibrated through air-fuel mixture and ignition timing optimization, raising the maximum horsepower output point to 7,400 rpm (from 7,000 rpm). To obtain a natural acceleration feel, the torque curve from low revs to the maximum torque point (5,200 rpm) was tuned for linearity. As a result of both the exhaust system and engine management changes, the IPL G Coupe generates 348 horsepower – an increase of 18 horsepower over the non-IPL models – and 276 lb-ft of torque (+6 lb-ft).

For better handling and road grip the 2011 Infiniti IPL G Coupe also comes with a stiffer suspension, upgraded brakes with ventilated discs on all 4-wheels plus aluminum-alloy 4-piston brake calipers at the front and 2-piston opposed rear calipers.

"When you drive the IPL G Coupe, the first thing you notice is the surge in sound and acceleration feel. The inspiring swell of sound is in complete harmony with the acceleration feel as engine speed increases," said Poore. "The sound is clean and inspiring, adding to the fun-to-drive sensation provided by the 348 horsepower under the hood.

The closest G to the IPL in today’s lineup is the G37 Sport, which comes similarly equipped to the new IPL G Coupe and starts at $41,275 with a manual transmission. The IPL has more standard features and the more powerful engine, which leads us to believe that it will wear a price tag just north of $46,000 when it goes on sale in December.
