430 4v. - 1991 to 1994
The new 4 valve-per-cylinder heads were adopted on the 430 from 1991, boosting the power output to 278 bhp. The car was assigned the 430 4v. nametag, to differentiate it from the base model, which was maintained. Both models benefited from the latest styling upgrades: new slimmer headlights, wider front grille, new bumpers and sills, 7-spoke alloys and spoilers on the boot lid and at the base of the windscreen.
Equipped as standard with the active electronic suspension control, the 430 4v. was seriously sports-oriented, albeit without giving up on superior interior refinement. With a top speed of 255 km/h (158.4 mph), the new model ranked amongst the most exclusive saloons in the world, a mere 291 of which were built in three years.
