What, Germany? They have no speed limit in many places, and there are plenty of German cars (eg. Merc, BMW) that can do 150+ mph. I was explaining to Lazs2 further up ^ that these high spec euro cars are speed limited to 155, but could do more... Even 3.0 V6 eurodiesels can nudge 150. A 4.0 V8 will romp past 150 and then top out at 155.
The difference is that these cars can average ~35mpg. How many American muscle cars/hot rods can average that? How many can average even 20mpg?
Oh yeah, then there's "chipping". Chipping is a process in which an engine is connected to a computer (a normal PC) through its diagnostic port. The computer "reprograms" or "remaps" the engine management chip to optimize performance. I knew someone who had this done, and he said the PC beeped 3 times - job done! His car instantly had an extra 25% hp. That was a gasoline car - he figures the boost for diesels can be 30% with a cut in fuel consumption thrown in. OK, maybe not the kind of engine mods that guys like Lazs2 do, but this is 2007...
