2011 Infiniti IPL G Coupe. Photos by Anne Proffit.
The IPL version of Infiniti's 2011 G Coupe makes a good sports coupe more balanced and powerful than the standard, Journey model. With its swoopy front and rear zero-lift fascias, pronounced side sills and small wing at the rear, the IPL looks almost as menacing as it is behind the wheel. The new model year's LED tail lights and inset fog lights tell the difference between it and last year's model.
I found the standard G coupe a rather bland machine when I tested it but thoroughly enjoyed my week in the IPL. With power increased from 330 to 348 horsepower (at 7400 rpm) from the 3.7-liter DOHC V6 and torque up to 276 lb-ft at 5200, the IPL G coupe from Infiniti has brawn to match its handsomely brutal looks.
With a smooth-shifting close-ratio six-speed manual transmission with short-gated shifter mated to this extraordinary engine, propulsion is instant and satisfying throughout the rev range. Viscous limited slip differential is standard. An IPL-tuned dual exhaust has the biggest pipes I've seen on an Infiniti; their growl is purposeful and the chrome tips add elegance to the package.
Sharp handling is accomplished through IPL-tuned double wishbones and multi-link front and rear suspensions with stability bars at either end. All-wheel power ABS-equipped ventilated disc brakes are superb, particularly with the optional ($370) R Spec high friction brake pads applied to this car. Speed sensitive variable assist power steering with sport-tuned 14.7:1 ratio adds dynamics to every movement. The turning circle is 36.1 feet.
Dimensions for this four-seater rear-wheel-drive coupe are just right at 185.1 inches length, 71.8 inches width and height of 54.9 inches, all riding on a nice, long 112.2-inch wheelbase. Weight, with all the standard features on this car is 3718 pounds, not a terribly sporting number but one the balanced drivetrain can deal with.
Infiniti fits staggered 19-inch Bridgestone tires on the Infiniti IPL G coupe with 225/45R rubber at the front and 245/40R at the rear, all riding on twinned 7-spoke polished alloys. Suffice to stay they stick!
Mileage for the IPL G coupe is rated a couple of miles lower than the standard G at 17/25 mpg from the 20-gallon tank. Premium fuel is highly recommended. My mileage hovered around 21-22 mpg with mostly in-town trips.
