This wasn't intended to be a debate about if Koenigsegg qualifies as a production car. Dunno said the Demon will have so much power that others will tuck their tails and run, and that if we had a Demon powered Viper Koenigsegg would have to watch out. This was strictly about HP numbers. Koenigsegg's 1360HP is a lofty number to shoot for. Not that it matters much, but Koenigsegg's V8 started life as a Ford Racing crate motor. It's since been completely modified but retains many of the dimensions.
