Compared with the standard car, the Nismo will prompt comments along the lines of 'not shy' thanks to its aerodynamic bodywork revisions and red 'pinstripe' detailing.
The former includes a 'double canard' front bumper treatment with aggressive lower lip, and a not insubstantial rear wing and diffuser. Slithers of wheel arch spats smooth airflow up front and accommodate new 285-section rear tyres (up from 275 on the standard car). All told, the Nismo is now said to approach 'GT-R levels' of downforce, resulting in 'zero lift.'
Alongside the increase from 328hp at 7,000rpm to 344hp at 7,400rpm, Nismo also sees torque rise from 267lb ft to 273lb ft. While this continues to peak at 5,200rpm, we're promised improved throttle response was the priority, so the 3.7-litre V6 should feel livelier from as little as 2,000rpm. A bespoke exhaust system certainly guarantees extra noise.
Suspension mods include revised '15-20 per cent stiffer' springs and dampers, though Nismo has resisted dropping it more than 'about 10mm' in order to maintain acceptable amounts of travel for the road. 19-inch wheels are standard, wrapped in bespoke Bridgestone Potenza rubber, while brake upgrades are limited to rigid hoses and fluid from the GT-R.
No word on pricing yet, but the fruitier 370Z is set for UK launch in June-July 2013.
