The legendary win of Porsche was a result of hard and persistent work of Porsche System Engineering and their drivers such as Jo Bonnier and Dan Gurney. Remark: Porsche 804 was created and firstly tested in 1961 (!) but officially raced from 1962.
Super short overview: The path to win started in 1957 through Formula 2 series which was allowed to start with Formumal 1 cars on 4th of August 1957 at Nürburgring. Finally the idea of super light 550 was evolved to 718 close-wheels coupe and finally to 718/2 and 787 monoposte (open-wheel – italia), and finally Porsche 804 was firstly tested on Nordschleife circuit in 1961 and took 2 grean wins next year in 1962 on France GP Rouen-Les-Essarts and non-championship race Solituderennen (Solitude GP) at Castle Solitude in Stuttgart, both by californian Dan Gurney.

The car has 6 speed gearbox and it allows to keep RPMs always more then medium, so car don’t lose speed on any of gear changing. It is well balanced, stable on high speed corners, however driver should be carefull on the acceleraion after goung out of the slow speed corner. If so, or going on bumpy surface (such as Solituderennen with there hills), it might be better to gear up a bit early (7500-8000 rpm), not going up to 9000 RPM limit.
Recomended to set brake bias on 65%, to prevent brake lock. Rear tyres wears a bit faster then front ones.
What is inside
Prepairing for 1962 Formula 1 season, Porsche was having looked at 12 and even 16 cylinder designs, they finally settled for a flat-8. The new Type 753 engine featured a magnesium crankcase with 8 separate cylinders. Each aluminium cylinder sported an aluminium-alloy head assembly of their own. Inside the individual heads were two valves, which were actuated by twin overhead camshafts. A shaft was also used to drive the horizontal fan for the air-cooled engine. The components were designed to run at over 10,000 rpm but peak power was initially produced at around 9200. There the 1495 cc engine developed just shy of 180 bhp. That was not quite as much as the competition but the Porsche engine did not have to drag large water radiators through the air.
Front suspension was through double wishbones, which actuated longitudinal torsion bars. The top wishbone was connected to the shock absorbers, which were mounted vertically and in-board. At the rear a similar configuration was used, although only one torsion bar was used that doubled as an anti-roll bar.
Interesting fact: the driver could turn off the engine fan for a very while that gave encrease of extra 9 horse power!

– Compatible physics to real car, suspesion geometry, RPM to Torque ratio etc….
– very compatitive AI
– shift animation is a bit weird
– animated suspension

What was after 1962 victory
Towards the end of 1962, Porsche ceased its Formula 1 programme. Such technology, with only minimal carryover to production cars, required heavy financial outlays. Since motor racing was always the basis for new developments and improvements to production sports cars at Porsche, the company concentrated instead on GT cars and long-distance events once again.
The Porsche proved they can do it, that was fair enough.
Where are Porsche 804 now
During the 1962 season Porsche used three different 804 chassis. A fourth car was also constructed but never raced. It is believed that at least three examples have survived. Gurney’s Rouen and Solitude winning car is among the survivors and has been part of a French collection for many years. Chassis 02, used mostly by Bonnier, was bought from the factory in 1964 by Tom Wheatcroft. Still in absolutely original condition, it can be admired in the Donnington Grand Prix Collection museum. The Porsche Museum owns the fourth car, which never raced in period. In recent years it has been given regular outings at events like the Goodwood Festival of Speed.
