Here's the breakdown:
* Rudolf Diesel invented the diesel engine in 1892.
* The first diesel car was built in 1897 by Dr. Friedrich Krupp, a German industrialist, using a diesel engine designed by Rudolf Diesel.
* This car was called the "Krupp Dieselwagen".
* However, the Krupp Dieselwagen was not a commercial success. It was slow, bulky, and had technical issues.
It wasn't until 1924 that the first commercially successful diesel car, the "Benz DB 601", was introduced by Mercedes-Benz.
