Technically not a concept, it still deserves a spot on this list. This one-off made for Fulda Tires could have saved Maybach from its death if it was actually sent into production as a Bugatti Veyron rival – or even just an example of what next generation Maybachs could look and perform like.
Instead, Daimler condemned the Maybach brand to death through the sort of badge engineering we haven’t seen since 1990s General Motors.
The design of the Exelero is clearly the standout feature, with its throwback looks and gangster styling. The grille says it all, hiding a twin-turbo V12 engine which makes 700-hp.
As mentioned, one running version of the Exelero was made, and reportedly sold to rapper Birdman for a whopping $8 million.
