I'm confused, Alfa Romeo built a streamlined Castagna in 1914:

Whay are you confused? The Castagna was not a production car, but a concept car made in a single copy. // Liftarn

speed/power efficiency[edit]

Hmmm ... 70mph/110kmh from 36hp isn't particularly impressive today, where you'd expect more like 80mph/130kmh from that power output. But I guess it was extremely impressive for the 1920s? Is there any way to rewrite the respective sentence that doesn't make it seem like an overall astonishing achievement by modern standards, but underlines that it was revolutionary by those of 90 years ago? Also, how fast did the 50hp model go? (A modern car of that output would manage low 90s mph/approx 150kmh...) 146.199.0.170 (talk) 21:09, 7 November 2018 (UTC)[reply]

It's unclear whether the mentioned Vmax of 110 kph is the actual top speed of the Tropfenwagen, as many manufacturers of this time gave only an approximate Vmax for various reasons. For comparison with a more modern vehicle, the Fiat Panda 34 of the 1980s with 34 hp was capable of 125 kph with a higher cW but only half the weight of the Rumpler, and the Italians had invested more time in the calculation of the optimal gear ratio than Rumpler did.

Most modern cars in the 45-60 hp range do manage top speeds between 140 and 160 kph. Would be interesting to know how a Tropfenwagen with the technologies of today would fare. 89.183.60.119 (talk) 09:18, 21 March 2021 (UTC)[reply]
