In mid-June 1992 the Alfa Romeo 155 range was enriched with the Q4 version, where "Q" stood for Quadrifoglio and 4 for four-wheel drive. The external appearance remained the usual one, but the technical innovations were of the highest level. The four-wheel drive was permanent and the engine was a 1995cc 186 horsepower for a top speed of 225 km / h. In 1995 the 155 range was updated and the Q4 also had the same changes in general. For the Q4, a Sport set-up was also planned with a lowered suspension, rear wing and tires with a lower shoulder.
