In September 1981, Fiat displayed the "Ritmo Abarth 125 TC" at the Frankfurt Motor Show. This model was not available for right-hand export markets because the position of the exhaust downpipe did not allow for a relocated steering column and system. The 125 TC was a modified and revised 105 TC with a 1,995 cc DOHC four with , ventilated front discs, a new five-speed ZF manual gearbox, revised suspension settings and strengthened components. Outwardly, the 125 TC differed only slightly from the 105 TC – it gained the chunky four-spoke 14 in alloys later seen on the Bertone Cabrio models, featured an "Abarth" red and black badge on the rear hatch, and the side badges featured the Abarth "Scorpion". The 125 TC version had a top speed of and it could accelerate from 0 to in 8.7 seconds. These cars were the last ones assembled on a separate Abarth production line, following the Fiat buyout in 1971.
