Maserati - Maserati 2000 Biturbo
Introduced in 1981, the Maserati Biturbo was the front engined more conventional model with the 2 litre engine, using the 3 valves per cylinder V6 Maserati engine. The twin turbochargers made up for any lack of capacity! This was the first twin turbo production road car, based on a V6 engine designed originally by Guido Alfieri.In the UK motorcars had added to the price something called purchase tax, started in 1940 at 33% to discourage people from buying luxuries and increased to 100% in 1943. Post war the rate was set at 33.3% which is why the UK car industry relied so heavily on exports - this 33.3% tax carried on until 1973 when a new tax (initially 10% vat) was introduced. The way Italy did it for motorcars was to have 19% purchase tax on cars up to 2 litres capacity, and then anything over 2 litres (which was deemed surely an unnecessary luxury) had 38%. So having the Maserati Biturbo at under 2 litre capacity dropped the showroom price by some 20%. The Biturbo sold really well, and from 1983 onward the Bitubo came with a 2.5 litre option as well.
The Biturbo started off as a 2 door 4 seater and the boost was continually increased for more power as the chassis was improved and the bodywork revised. A 4 door longer version was available by 1983 and this model range evolved from the type 420 and 425 to 430 in 1986, 422 in 1988.
Maserati 2000 Biturbo tyre size was originally 195/60HR14 , a size no longer made in a suitable tyre, but this size is virtually identical to the 205/70VR14 size offered by Blockley, which is the size everyone uses.
