Re: Onboard diesel-electric
It's at this point, I remember Porsche's first attempt at these.
Quite famous for catching fire when being trialled against the alternative design from another company which lost them the contract.
Of course Porsche had already begun building a few hundred of them and had to re-purpose them. They still didn't work very well and kept breaking down.
Interestingly enough, we Brits were also working on the same technology. The vehicle it was mounted in was a failure, but the mechanics worked!
FYI, yes, I am talking about the VK 4501 (P) and the TOG II*
