Why it matters

The Prinz-Heinrich cars were Benz's purpose-built entries for the 1910 Prinz-Heinrich-Fahrt, nominally production four-seat touring cars but streamlined and tuned for competition. A surviving 80 hp car in the Louwman Museum shows how the event's touring-car rules were stretched.

Production

Every figure says what it counts.

What is countedFigureBasisStatus
Total model productionof the cars Benz built for the 1910 Prinz Heinrich Tour, two are known to survive in original form (per the conceptcarz profile of the Mercedes-Benz Museum car). A separate 1908 profile says only four of about ten built exist today. 21,3 Surviving examples Independently researched

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

The Prinz-Heinrich-Fahrt, named after Kaiser Wilhelm II's brother, was a six-day event of almost 2,000 km through Germany and France for four-seat production cars, with an observer from the Kaiserlicher Automobil-Club riding in the back. Benz built torpedo-bodied cars with streamlined headlamp covers, disc wheels and a radiator shroud, in 80 hp and 100 hp forms built only to order. The Louwman car finished fifth in 1910, when Ferdinand Porsche won in an Austro-Daimler.
