Serious errors in Reference 3

Reference 3, as it is at this time: http://www.fiat500usa.com/2009/02/dante-giacosa.html

The quotation may be correct, but the original article is very, very wrong in having a go at the Issigonis designs.

The transmission was integrated into the engine sump and shared the same oil supply. This is not a desirable feature for several reasons. First the difficulty and expense of manufacturing. Second , servicing is much more difficult, Thirdly, engines and transmissions like to use oils with different characteristics. And an automatic transmission would be nearly impossible.

Well, as it turned out, manufacture was not seriously difficult or expensive, servicing was straightforward, and there was an extremely successful automatic, many examples of which are still running to this day.

These cars also had a radiator fan driven by the engine with the subsequent radiator mounted in the right side fender well. This location was not ideal as it limits packaging alternatives.

Well, we see Mini, and its derivatives, mechanicals used in many specialist vehicles, including front and mid engined kit cars, so evidently the packaging limitations were not at all significant.

Dante Giacosa wanted to separate the engine and transmission to eliminate these problems, so with the 1964 Autobianchi Primula he did. Up until then, most front wheel drive cars had to have the engine and motor removed to change a clutch. This car was the production test bed for Fiat to try out their front wheel drive concept originating with them in 1947.

It is the Giacosa (and followers) layout that requires the engine and/or transmission to be removed from the vehicle for clutch replacement. It is NEVER necessary in the Issigonis layout, where the clutch is largely external to the engine/transmission assembly. Nor is it necessary in the other slightly later FWD implementation in the Triumph 1300, with fore and aft engine.

The referenced article is full of bias and should be identified as such. — Preceding unsigned comment added by Tiger99 (talk • contribs) 17:45, 27 August 2017 (UTC)
