A few months later the Ritmo Abarth 125TC was introduced in Europe; it was never officially sold in the UK, as the position of the exhaust downpipe would have clashed with the Right Hand Drive steering gear. The 125TC was a heavily modified and revised 105TC with a 1995 cc DOHC with 125PS (92kW; 123bhp), ventilated front discs, a new ZF gearbox, revised suspension settings and strengthened components. The 125TC version had top speed of 188km/h (117mph) and it could accelerate from 0 to 100km/h (62mph) in 8.7 seconds.Significantly the Abarth models were the last true Abarth cars to be assembled on a separate Abarth production line following the Fiat buyout in 1971, thus ensuring the car of Classic status.
Technologically, the biggest innovation of the Ritmo was not the car itself, which took the underpinnings of the 128, but the way in which it was manufactured. Fiat, already an industry pioneer in automated assembly, took the ambitious step and made the Ritmo the first car to be almost completely built by robots, earning the car the advertising tagline "Handbuilt by robots".
A 1982 facelift saw the Ritmo's styling become more restrained with more conventional re-designed front and rear ends. Base models sold on the continent featured the by-now familiar 5-bar grille with single round headlamps set in a conventional grille, whilst all other models featured twin round headlamps (in the UK, all models of this generation featured twin headlamps). The rear gained conventional light clusters either side of the rear numberplate. The 105TC was relaunched with revised interior trim, a dashboard mirroring that of the earlier Ritmo Super, and an upper hatchback spoiler in place of the lower one. In the UK, 7-spoke alloy wheels replaced the earlier Speedline ones. The advertising name was revised to Strada II in the UK, although the car remained badged as a Strada. The US version was unchanged but discontinued at the end of the 1982 model year, leaving only sports cars in the US Fiat lineup (X1/9 & 124 CS). Most significantly, a hot hatch version — the Abarth 130TC — was added. This model was based on the 125TC with a 1995 cc engine, but with performance increased to 130PS (96kW; 128bhp) by replacing the single Weber carb used in the 125TC with twin Solex/Weber carbs on a side-draught manifold, and improved cam profiles. The 130TC was capable of 195km/h (121mph) and accelerated from 0 to100km/h (62mph) in 8 seconds. It was a raw hot hatch fitted with Recaro bucket seats as standard in the UK (optional in Europe) and significantly it was the only 1980's hot hatch to continue utilise carburetors instead of fuel injection coming with either twin Solex ADDHE or Weber DCOE40 carburetors. Ignition timing was controlled electronically. Although appearing outwardly similar to the restyled 105TC with its lower door & wheelarch trims, the 130TC could be distinguished by its polished 4-spoke alloy wheels, aerodynamic perspex front door wind deflectors, and lower hatchback spoiler. The raw powerful twin-cam mated to a close ratio ZF gearbox made it a handful to drive, with the performance to outpace many of its contemporary rivals such as the Volkswagen Golf GTi, Ford Escort XR3i, Vauxhall Astra GTE and the MG Maestro.
