Pre production and test cars


Before the actual production of the SZ started, a number of test cars were used at Alfa Romeo, some only for studies and photo shoots, others for wind tunnel, crash and drivability tests etc. etc.

Prova

The first "mules" were Alfa 75s with the engine and suspension modified to match future SZs. One of the 2 Alfa 75s ( red one ) was driven on the test track of DAF, in the Netherlands. Unfortunately no other proof of this car remains today, apart from the pictures above and below. The other ( blue ) mule has been used in Italy for all kind of tests.

This Alfa 75 was endurance tested by the KONI crew.

Prova

After 1000km on the test track, the car nearly disintegrated. The dashboard and Engine Control Unit literally fell apart because of intense vibrations (surely KONI must have had fun doing these tests) but the KONI shock absorbers continued to perform well. Once, the same Alfa 75 made its appearance at the Zandvoort race track during an "Italia" weekend. Apparently it drove like a cart and proved to be much quicker than the SZ because of 200kg weight reduction. Alfa originally aimed at the 75s weight but because of the increased thickness of the modar body shell, the SZ turned out heavier than planned. Consequently the first SZs produced, sat too low to the ground and KONI was forced to modify their design for the shock absorbers and springs. You can imagine the panic when the first car appeared at the end of the production line!
That first ( 75/SZ ) mule ended its short life by hitting a tree on the KONI test track by the way... Koni had to send the remainings back to Alfa Romeo !

Highly camouflaged first prova at the Balocco track.

Prova

The pictures show the first test car that was presented to a very select group of people at the Balocco race track. The car was heavily camouflaged. Taking pictures during that phase of the ES-30 development surely must have resulted in the dead penalty, so you can imagine how unique these pictures are!

Prova

The grand totall production for the SZ was 1036 cars of which 38 were prototype and pre-production cars destined to be scrapped, but some of them are still existant.

During the test period of course several changes were implemented in the design of body parts, interior, instruments, as well as in the technical specifications. Some changes more dramatic than others. Interior parts were custom made and were often not very nicely detailed.

Prova at the Silverstone (UK) circuit, also used in Germany. Look at the front and rear bumper, the lamps etc.

Some pictures are from an early test car with chassis number 0004 and some pictures are of later test cars, respectively numbers 0016 and 0017.
The pictures are showed in random order.

Prova

Differences in the bonnet and the pop riveted wings above the front wheels from the above car seem to be much wider than on the later SZ's.

Missing ricambi number on the aluminum plate.

Prova

The boot lid is black and differences can be noticed in the brackets to attach the spare wheel belt. The pump is also a prototype

Prova

Prova

Boot lid has been isolated and the trunk itself has some carpets like the interior.

Prova

Exterior - among other body parts the mirrors where smaller and different from the mirrors on the production cars. Sometimes you will find these same mirrors on the first 20 to 30 production cars. On some cars you even will find a "normal" left side mirror whereas the right side has the "pre-production" mirror, or the other way around.

Prova

No service access panel in the mudguards. Even first 20 ? production SZ's had a slightly different front bumper without a service access panel in the mudguards. Consequently the lamps where mounted in a different way and when a lamp had to be replaced, the bumper had to be taken off the car !

Prova

Differences in the interior, most parts have been stitched roughly, colours of mats and other panels are not matching etc.etc.

Prova

Surround around the word "Zagatodesign" on the headrests of the front seats.

Prova

The inside of the doors has been painted black on all the test cars I have seen.

The red "handbrake on" indicator light is different

Prova

Sometimes instruments with hanging needles, others have standing needles.

Prova

The panels are made of real kevlar / carbon, unlike the plastic imitation kevlar panels as fitted to the production cars.
