Of course, a couple more pipes and ponies don’t make a great sports car that much greater, so Infiniti also modified the suspension spring rates, added a higher-performance braking system, fitted a gorgeous body kit, some great wheels and a set of Potenza performance tires. There’s some extra badging on the trunk lid and engine cover to tie it all together.
But it’s modest looking. Sort of. The IPL doesn’t solicit much more attention than the G37’s sexy, scowling bod already demanded. It’s like that hot girl at the office, wearing an extra-sexy getup on dress-down Friday.
In traffic, it gets big reactions from those in the know, but slips gracefully by the motoring masses without much second thought. Or blows by them with a howling exhaust note in its wake. Driver’s call.
Blasting along
Acceleration is generous, liquid-smooth and potently peaky as the tach reaches for redline – though the extra 18 horsepower are perhaps lost in the pack. The IPL is quicker than the standard G37 Coupe, but not incredibly so.
The tester shifted gears via a 7-speed, paddle-shiftable automatic with downshift rev matching and throttle-cut upshifts. Translation? Pleasingly quick and smooth shifting is available in both directions. Manly men can opt for a 6-speed manual transmission, too.
The IPL braking system bites down with authority from the first press of the pedal. Though occasionally abrupt, strong pedal feel, easy modulation and a precise, powerful character to the entire setup inspire confidence should one’s radar detector start beeping.
Steering is light and loose during low-speed work, though it firms up nicely to bridge the gap between fingertips and tarmac at higher speeds. On a winding side road, the IPL’s steering gives drivers a clear sense of vehicle weight and attitude. It feels locked down and heavy in both the front and rear, but also eager, confident and naturally athletic.
