I think it's badass. But that's just me. It's available to view on the ACS website. It's a 3er coupe with the S85 V10 (M5/M6) engine that runs on propane and was created for an auto show and alternative energy "contest" of sorts. It's currently the fastest liquid-gas fueled car in the world, reaching 318.1 km/h (197.6 mph). Pretty cool concept, except that propane costs WAAAAY more than gasoline and is much more volatile.
