This Abarth is largely Fiat Punto, as explained, but there’s a lot more than window dressing here. The 1.4 T-Jet engine, now producing 153bhp rather than the 120bhp of the Punto Sporting, has been analysed using fluid dynamics disciplines to improve its thermodynamic cycle, from the combustion cycle through to its cooling system.
The result is a redesign of the intake and combustion systems, the camshaft profiles and timings, the intake and exhaust manifolds, coolant circulation and the spark plugs.
The reworked combustion chambers allow the use of a smaller, more responsive turbo, and low-end torque is further bolstered by a drive-by-wire throttle. In fact, there are two map sets, selected via a dash button.
Sport mode lifts peak torque from 152lb ft to 169lb ft at 3000rpm and produces a livelier throttle response, while the standard setting is intended to make the car easier and more economical to drive.
Sport also alters the electric power steering’s weighting. This is hooked up to a new variable-ratio rack to quicken turn-in and it’s mounted on firmer bushes for additional precision.
The Punto’s MacPherson strut front/twist beam axle rear suspension set-up is retained, but with mechanical and electronic modifications.
These include a thicker front anti-roll bar, 20 per cent stiffer front springs, a 10mm lower ride height, tauter dampers, firmer bushes and 215/45 ZR17 low-profile tyres.
The standard ESP is unusual for not cutting the engine’s torque when countering understeer, allowing more fluent and faster exits from hard-charged bends. It can’t be switched off, although its traction control software can.
Supporting these mods are a subtle bodykit, a new front bumper with bigger air intakes and foglamp shrouds, a tailgate spoiler, attractive 17in alloys and a light smatter of Scorpion badges.
The overall effect heightens the already handsome Punto’s appeal.
