IPL: Infiniti spells performance with new custom line to debut on G coupe

Time will tell whether the IPL brand will carry the gravitas of Mercedes-Benz AMG or BMW M. But for now, it spells 18 hp and a host of sporty cosmetics.

Infiniti is launching a range of athletic gear for its luxury cars, called Infiniti Performance Line. The first car will be a reworked version of the G coupe, packing 348 hp when it arrives in December.

The IPL G coupe, which is being revealed this weekend at the Pebble Beach Concours d'Elegance, adds a bit more gusto to the rear-wheel-drive car. The 3.7-liter V6 engine is boosted from 330 hp in the conventional G coupe thanks to exhaust and engine-management upgrades. Torque is up 6 lb-ft to 276 lb-ft. Engine redline is increased from 7,000 rpm to 7,400 rpm, and the torque curve is modified for more linear acceleration. The engine is paired with a seven-speed automatic or short-throw six-speed manual.

The sheetmetal is dressed up with new fascia and bumper designs, integrated fog lights, side sills, rear spoiler and chrome exhaust tips. The car rolls on 19-inch IPL wheels split by seven spokes finished in graphite. The coupe will come in graphite and black. Inside are red leather seats, a red stitched steering wheel and aluminum trim.

Infiniti says the suspension is worked over considerably to produce a flat and smooth ride. Front spring rates are increased 20 percent compared with the base G coupe, while rear spring rates are increased 10 percent. The steering and shocks also have been retuned, and stopping comes from four-wheel sport brakes with aluminum-alloy calipers. It's all topped off with the IPL badges.

Pricing was not immediately announced. IPL will be offered in North American vehicles and is being evaluated for other markets.
