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.
