The 422 was introduced in 1988 as a replacement for all previous versions of the 420 four-door family, including the 420 Si from which its mechanicals were derived. The car was restyled with a new front grille, mirrors and five-bolt alloy wheels. In 1990, the 4.24v mirrored the two-door 2.24v, using the latest four-valve-per-cylinder, four overhead-camshaft V6 engine. Styling enhancements (including blacked-out chrome trim, specific bumpers and rocker panels along with a discreet spoiler on the trunk) conferred a sporty yet refined allure to this high-performance sedan. The independent suspension featured active electronic control on all four wheels, while the interior’s mix of leather and wood trim conveyed a feeling of exclusivity. Launched in December 1990, the 4.18v was similar to the 422, designed with smaller displacement for the Italian market. Its main feature was ABS fitted as standard, a first for the Biturbo family. Produced in only 77 units, this particular model is unquestionably one of the rarest models within the Biturbo range.
