Scam.
The Scuderi Group has been saying this for well over 10 years now, and have yet to deliver a vehicle that is propelled by this engine. It could be any vehicle. Even a vehicle like a go-kart.
Scuderi claims that their engine technology can easily be retrofitted to a normal engine. Okay, if this is so, then they should show us.
If some unknown 50+ year old engineer can spend 1200 hours and create a complete miniature V-12 that actually runs, surely a multimillion dollar group can come up with one working prototype engine that can push a vehicle forward.
