Alfa Romeo Alfa 6

History

On its launch in 1979, the Alfa 6 was the flagship of the Alfa Romeo range. The four-door body was fairly conventional and used a similar style to the existing Alfa Romeo Alfetta, and in fact both vehicles share a great number of parts, including door panels; Design work on the 6 was done prior to the Alfetta, but the fuel crisis of 1973 delayed further development and led to the 6's belated 1979 debut. The styling was not particularly aerodynamic but the drag coefficient was an acceptable 0.41. Power came from an all-new 2.5-litre V6 engine which generated 158 PS at 5,600 rpm using a total of six carburettors and a single, belt driven camshaft in each cylinder head. Power steering, power windows, central locking, electric wing mirrors and a 25% limited slip differential were standard, making the Alfa 6 competitively priced compared to similar saloons of that time where such equipment typically was a costly extra. The car was also designed to set new standards in safety; for example it featured a shock sensor in the boot which would cut off the fuel supply in the event of a crash.

Facelift

In 1983, the car was revamped, with single rectangle headlights replacing the twin round units, new bumpers, a new grille and new trim around the rear lights. Minor interior changes were also carried out, whilst mechanically the engine's troublesome six carburettors were replaced by Bosch L-Jetronic fuel injection, with the power remaining at 158 PS. This revamp also saw the introduction of two new engines, a 2.0-litre version of the existing V6 engine (which retained the carburettors and was specific for the Italian market, where engines larger than two liters were heavily taxed) and a 2.5 litre VM 5 cylinder turbodiesel.

The Bertone Delfino concept car in 1983 was based on an Alfa 6.

Specifications

The engine and gearbox were situated at the front and a limited slip differential at the rear. The 6 was fitted with four disc brakes, with the rear ones inboard, to reduce unsprung weight. The 6 has De Dion tube at the rear and it has independent front corners, the gearbox was also located in the front. Two different 5-speed gearboxes were available: one with a "normal" layout, the other with "dog-leg" layout. A three speed automatic transmission from ZF was also available as an option and the ZF hydraulic power steering was the first to be fitted to an Alfa Romeo.
