Wist je dat VW in 1951 twee VW diesels heeft gemaakt op het blok
van hun luchtgekoelde 1.300 cc boxer? Daar is er eentje van in een kever ingebouwd geweest
en één in een busje.
In 1951, Volkswagen prototyped a 1.3 L diesel engine. Volkswagen made only two of these naturally aspirated, air-cooled boxer diesel engines, and installed one engine in a Type 1 (project number 508) and another in a Type 2. The diesel Beetle was time tested on the Nürburgring and achieved 0–100 km/h (0–62 mph) in 60 seconds.
Impetus for their original contract came from the very low diesel fuel prices of 1951, as well as Korea-war related shortages of gasoline. Then VW chief Heinz Nordhoff visited the U.S. and returned convinced Americans would never drive automobiles, which rattled while idling and produced little perceptible power. Project 508 became another of those many, many Porsche designs for VW, which fell into a back drawer. Before that, however, they had fitted one to a Beetle and another to a VW van.
Since these test engines displaced 1290 cc (74.5 x 74 mm), and could extract 23 hp initially and 25 at 3100 rpm by the end of the project with a rev maximum of 3300 and weight penalty of only 45-55 lb. Such power was hardly thrilling; but then, the everyday Beetle wasn't all that much faster.
Even so, their diesel was slow enough that Porsche engineers still wonder what the person thought who stole the world's only diesel Beetle from a parking place in Germany. Despite a long wait for pre-warming and curious fuel needs, the thief drove it all the way to Switzerland before abandoning his smokey, noisy and slow free ride.
