2011 infiniti IPL G37


New 2011 348 Horsepower IPL G37 Coupe


Announced on August 12, 2010, Infiniti will be releasing a new performance initiative that is simply named "Infiniti Performance Line", or IPL for short. IPL will be similar to Nissan's NISMO initiative
where manufactured-warrantied parts, as installed by dealerships, will be offered to the public along with low-production speciaty vehicles. This is not a new concept to Nissan as they have been releasing specialty vehicles in Japan for quite a number of years and have been offering NISMO-tuned offerings for the Nissan Z-series lineup as well. From an Infiniti perspective, the rumors have been true and it's now officially announced. Per Infiniti Vice President Ben Poore:

“IPL was conceived to create a new premium performance envelope, going beyond equipment upgrades to accelerate the very soul of Infiniti’s Inspired Performance, IPL brings all the elements
together, styling harmonized with performance, exhaust note with acceleration feel, ride comfort and confident handling. It’s the perfect formula for unmatched driving exhilaration.”

With the announcement of the IPL offering, and a debut of the vehicle at the Pebble Beach Concours d’Elegance, Infiniti will be offering a new tuned-performance G37 coupe starting in 2011.
