In 1972 an Osella-Abarth won the Euro 2-litre Sports Car title.

Forza Arturo!

Why was that engine not an immediate contender for the new F2 rules in 1973?

This MUST have been covered before.

Perhaps it was too heavy?

Or perhaps the wrong shape.

Someone will know

Maybe it just wasn't good enough?
I recall being at the 1972 2-litre Group 6 race at Silverstone; until "circumstances/wet weather/virtuoso-performance-from-little-Art" intervened, Dieter Quester's BMW-engined Chevron was way faster than anything else - so the Germans were already on the case.

There's a very simple explanation: in 1972-1975, engine blocks and heads had to be homolgated, i.e. built in a minimum amount; in group 6, that was not necessary.
The only useable engine in 1972 was the Ford BDA, 16 valves and lots of trouble. BMW was not homologated until 1973, like the Lotus engine.
In 1972, the only alternative was the Fiat Dino engine, however this had only 2 valves per cylinder.

So was the Abarth not homologated in 1973 for F2?

The Abarth was a pure-bred racing engine and they weren't allowed in until '76 were they? (Renault V6 etc.).....

Or to put it another way, Formula 2 engines did not have to be homolgated (ie, production)

From 1976 onwards, yes. That's why we had Hart, Renault and Honda engines since, and a few oddities like Lancia, ROC_Chrysler and ... Abarth (a six-in-line in 1976...).

Abarth inline-6? I never heard about that one...

Anywhere I can have a look at it? I just love the howl of a straight six at full cry... when our 1600 single-cam (production based) F2 came in back in 1977, John McCormack suggested a Fiat 1800 with a bit of destroking. What a lovely thought!

As some of you are aware, I know absolutely NOTHING about engines, or indeed anything technical. However, I do recall the Abarth V6 was tried in F2 in 1976-77, in both Lola and Pilbeam/Wheatcroft chassis. Bit of a disaster in each, I have no idea why...

The car was indeed a Wheatcroft, called P26-Abarth, engine was designated as Fiat-Abarth L6-260, an inline 6 (no V6), with 4 valves per cylinder, quoted with 316 HP/10400, 1986 cc, bore x stroke 86 x 57 mm, interesting enough exactly the same as the Ferrari Dino V6 of 1977, as used by Chevron
:confused:

Memory slightly adrift (as usual) - I heard it (very closely indeed) at the International Trophy at Silverstone - in 77 for F2 cars. I wasn't at Thruxton in 77 - it was 78.

It was regularly warmed up in practice near to where I was in the pit garages - between Musetti's March and Lawler's Lola T462. God it was loud, but then so were the two Renault-Elfs of Arnoux and Pironi I remember.

Memo: I really must get my pictures posted...
