2012 Infiniti IPL G Coupe - CNET

The 2012 IPL G Coupe represents many things to Infiniti. For starters, the Infiniti Performance Line (IPL) is the automaker's first dabble into the kind of performance premium sub-branding that makes German luxury cars bearing an "//M" or "AMG" badge so alluring. Stepping up to the IPL G Coupe really only improves the G37 Sport in two measurable ways: it goes faster and it handles more sharply. We start our trip around the upgraded IPL G Coupe in the engine bay where, aside from the chrome IPL badge on the engine cover, not much is different from a standard G37. Yep, that's the same 3. 7-liter VQ37VHR engine. However, what you don't see is that thanks to a few ECU tweaks, Infiniti's engineers have managed to squeeze an extra 18 horsepower out of this mill. That torque number is only up by a scant 6 pound-feet, which may explain why the IPL G Coupe doesn't feel madly different from a G37 Sport. Zero to 60 takes about 5. 0 seconds, just 0. 2 seconds faster than the non-IPL model, which really makes any drag race between the two more of a driver's race than a hardware comparison. You'd really have to approach triple-digit speeds to feel any real difference between this and your neighbor's G37S. You wouldn't need to do more than idle the engine to hear the difference.
