For A-I-10, it also says: "...as defined until 31.12.2014 - classification under review."

My reading of the history books is that the Mercedes records set in 1939 at Dessau used a 3 litre engine (Class D as it was then, now Class A-I-8). Therefore they cannot be current FIA records.
On the other hand, in October 1934 Rudolf Caracciola with the Mercedes Benz W25 set Class C records of 197.347 mph (kilometre) and 196.775 mph (mile). Rather unusually the engine size was just under 4 litres in a 3-5 litre class. As far as I can tell these should be the current FIA A-I-9 class records.
"Tricky", sorry that I didn't answer before...we had for the last two days no phone or internet connection at my town...
I understand now what you like to say.....
Dessau 1939 was under 3 liter...no changes in the new FIA list
Gyon 1934, the engine was close to 4 liter....and the later record breakers used engines closer to 5 liter....maybe there will be not only a change on the short distance...the same engine was used at the Avus for long distance.....
I checked the record lists I got....digital goes back for about 20 years....unfortunately I have no complete list from the time before the big changes in 1965....
the record from Herda (1965) and Hoffman & Markley (1992) was set with bigger engines...H & M used a 300 ci (means close to 5 liter)...when I remember right, Herda's engine was similar in the size...
so I have no information which record Herda broke.....did you have any information to this record holder....
