How Fast Were The Silver Arrows of The 1930's? | An Assetto Corsa Experiment 

These cars were amazing for the era they came from. They developed everything but never explored wider tires for handling.

Great video - thank you for that! I find the old racing cars the most interesting and am always fascinated. Speaking of which: which flight simulator did you show there? (11:40)

It seems like only 140 mph would be a low-ball figure, even for the Bugatti Type 59, certainly the Alfa Romeo P3. And I'd think the Maserati 8CM would would be fairly close to the Alfa. And yeah, seeing the first comparison listing, it doesn't make sense to me how the Alfa is slower in the top end than the Bugatti, honestly. Looking again, um, are you sure that was the Bugatti Type 41? If so, I seriously have to wonder if something is wrong. The Type 51 definitely shouldn't be able to outpace the P3. And if the Type 51 really can do a 140 mph, then the Type 59, P3, and 8CM should all be good for 150-155 mph, maybe 160 mph. The Auto Union Type C has a 6.0-liter V16, producing, depending on the source, 520-545 hp. The Auto Union is supposed to have 5 gears. Btw, is the Auto Union Type A not yet available for early access? The W125 has a 5.7-liter Straight-8 engine, and yeah, depending on the source, it gives anywhere from 575-650 hp. The Mercedes really brute-forces it, whereas the Auto Union was of a more advanced design, and so had a better chassis and less frontal area. The big thing both German GP cars had was they were torque monsters beyond anything else out there. They made 600-700 ft-lb of torque, and did so well below redline. They weren't allowed to be more than 750 kilos when empty. The streamliners were built for Class B speed record attempts, but they did run special version of the cars here at AVUS. The Mercedes-Benz W196 Streamliner was used at Monza and Reims in 1954-55. I suspect the increased weight with all that bodywork helps keep it under control. Actually, it was Lang's Mercedes that tried to fly at AVUS in 1937. That 210-mph figure does seem like it's on the low side. Um, you didn't shift up to 4th in the Merc streamliner. It doesn't hurt that there was a version of that car with a 5.6-liter V12, and some sources claim a power figure of ~750 hp. The Mercedes Streamliner definitely has more frontal area than the Auto Union. As a final side note, the Alfa Romeo P3 pseudo-streamliner that won the 1934 Avusrennen has a claimed top speed of ~170 mph.

Is the final drive adjusted to as tall as possible.

the w25 easily passed 200mph in real life.
