Maserati 425

Just two years after the Biturbo had been launched, Maserati introduced a foor-dour variant based on a longer (2600mm) platform, which maintained the same styling. With the Quattroporte competing in a higher segment, the 425 marked a new entry for the Trident in a competitive market for fast luxury sedans of contained dimensions.

The official name depended on the engine equipped; Italian market sedans, with the tax-regulated 2.0L V6 were called 420, the carb’d 180bhp 2.0L V6; 420i, the fuel-injected 2.0L 190bhp V6 (1986+), or the 210bhp 420S.

All Italian-market 2.0L of this generation used the usual three-valve-per-cylinder head. In other markets, it was sold as the 425 with a 2.5L 18v V6, carb’d with no catalyst and 200bhp. There were a total of 2,372 425’s made, including later fuel-injected and catalyst-equipped 425i models. The next year, Maserati debuted the stunning drop-top Spider derivative at the Turin Motor Show in 1984. It rode on a shorter wheelbase than the regular BiTurbo, and was a strict two-seat design. It looked a bit like TVR’s of the time period, perhaps, but it was a twin-turbo Maserati convertible, by god!

The engine was the new 2.5-litre evolution of the V6 just introduced on the Biturbo for export markets. Twin-turbo technology allowed the 425 a top speed in excess of 215 km/h, whilst at the same time keeping the price reasonable.

The very refined interior featured ergonomic seats with velours designed by Missoni, or leather trim to order. The air conditioning was standard equipment, whereas a very elegant set of leather bags and suitcases was offered as optional.
