A trip to the Pikes Peak International Hill Climb shows the style of racing that developed countless Formula 1 champions.

Mercedes-Benz had arguably the most expensive car pairings to take on the hill climb, with its W 196 R and W 196 S from 1955. A 196 R was auctioned in Stuttgart, Germany, in January for $54 million.

German carmaker Porsche took a near-production prototype of the electric Cayenne to the Shelsley Walsh hill climb, it already set a record.
