The V-10 of MTU-MB 838 90-degree diesel of the Leopard tank is listed back as far as 1969 in the Leopard tank. 2283 cubic inches, 1400 to 1500 Horsepower. And has also has the words Renk applied in one case, meaning unknown.
Friedrichshafen: Motoren- und Turbinen-Union Friedrichshafen GmbH, or MTU for short. (This is the same company as Maybach.)
Type MTU MB 838 Ca-M500, 10-cylinder, 37.4 litre, four-stroke, multi-fuel.
Power 830 hp at 2,200 rpm. Used in German Leopard 1 Tank and other military vehicles..
This engine is now revised to MTU MB 838 10V @ 90 degree 1400HP diesel 6.496"(165mm) x 6.890175mm) 2283.5 cubic inches (37.4 Liter)
This means that the Renault case for the invention of the V-10 engine is not valid. They may have been the first to use this configuration in F-1 but to state that Renault Invented the V-10 is not applicable. It is even possible that MTU-MB did not invent it. Which is also possible, as they don’t claim to even be the first to use this configuration of cylinder arrangement. So the mystery continues!
EDIT. A message confirms the engines are much the same. But MTU does not claim to have developed the V-10 engine and did not reveal who did. M.L. Anderson
Edit 02-18-2002 After much searching this is what I found out about the Porsche of 1939 ,only three seemed to have been built by V W. It does not state that the car had a V-10 engine but seems to have been adapted to a flat four cyl. The V-10 was designed but the war interferred.
It comprised a pair of Porsche Type 101/1 engines of V10 configuration, each rated at 320hp. This is from the description of a German Tiger Tank of W W-2. Confirming Karlcars statement of the Porsche's V-10 engine around 1940-45. The two original Porsche Typ 101/1 engines were replaced with proven Maybach HL 120 engines. Some appear to have been converted to the Elephant type antitank AFVs. Not a successful type. Just how many V-10s were produced is not known but it must not have been many as they were replaced by Mayback HL210 P30s or 230,P45s not a very successful engine were the V-10s. But as Karlcars states they made progress in the V-10 and they may have sown the seed for later engineers.
