On 14 December 14 1981, precisely 67 years after Alfieri Maserati founded the Maserati company in Bologna, Signor De Tomaso introduced the long-awaited Maserati for the world.

The Bi Turbo had a V6 twin-turbocharged 2.5-litre engine with a single Weber carburettor driving through a ZF transmission. The Bi Turbo is about the size of a BMW 320i, and has many features borrowed from the BMW, including the front and rear suspension and steering. There the resemblance ends, for the interior is very luxurious. For 1986, a four-door Bi Turbo was added to the line -- numbered the 425: 'four' for four doors, and 'two-five' for 2.5-litre. Also in 1986, a stylish spyder by Zagato was added to the line, available with automatic transmission only and a blue convertible top. For 1987, fuel injection was added, which turned the car into a completely different animal.

In 1987, we got the 430, the new spyder and the 228. The 430 was a 425 with new sheet metal, the engine enlarged to 2.8 litres, quad exhaust, 15-inch wheels, twin air-to-air intercoolers and a lovely new interior. The new 1988 spyder also got the 2.8-litre engine as well as all of the above features. The 228, built on the 430 chassis, was wider and stouter with softer lines. It also came equipped with the quad-exhaust, 2.8-litre engine, air-to-air intercoolers, 15-inch wheels, etc.
