The Turbodelta

The Alfa Romeo Giulietta 2.0 Turbo Autodelta, known as Giulietta Turbodelta for short, was the last Alfa Romeo built by Autodelta. Autodelta had been Alfa Romeo's racing division since 1963, with headquarters in Settimo Milanese under the management of Carlo Chiti, and was completely taken over by Alfa Romeo in 1966.

The Turbodelta was developed with the aim of successfully participating in car races in the "European Touring Car Championship". The requirement for participation in these races was that 500 vehicles had to be built. However, only 361 Turbodeltas were built within 13 months in 1983 and '84. They were only available through the Alfa Romeo dealer net­work in Italy at a price of 26,940,000 Italian lire each. Due to the high price, the last cars built were not sold until 1986 with a discount.

The Alfa's engine was the well-known two-cam­shaft engine with a displacement of 1962 cc, which, with turbo support from the built-in Avio turbocharger, produced a stated 170 DIN hp. The compressed intake air was fed into two pressure-stable Dell'Orto 40 DHLA double carburettors. A waste gate and an oil cooler were also installed, but no intercooler. The turbochargers mentioned were replaced early on, usually still within the warranty period, with more reliable models from KKK.

Other changes made compared to the pro­duction vehicle were:

four internally ventilated disc brakes with two brake calipers per front wheel

a stronger two-disk clutch, taken from the Alfa Romeo GTV6

five-hole magnesium rims with Michelin TRX tires of the unusual size 200/60 HR 365

all Turbodelta are painted black metallic (nero metallizzato) with silver-grey plastic heels on the sides and bumpers, comple­mented by a surrounding red line at the height of the bumpers

the interior of all cars is dominated by the colour red, the seat colour is panno amaranto

seats from the Alfa Romeo GTV6 in red

Momo sports steering wheel with smaller diameter

boost pressure indicator mounted in the center of the dashboard instead of a venti­lation nozzle

Converted in this way, a Turbodelta weighed 1140 kg when empty. With this power boost, the Turbo­delta reached over 200 km/h and managed the quarter mile in 15 seconds. It was, is and will always be an Alfa Romeo for lovers and collectors of the brand.
