Many peoples talking about that the F1 car can be driven upside down in a tunnel because of their massive downforce. But, Mercedes SLS also can do that. Designed in-house by AMG, it will begin in the United States in mid-2011 for less than $200,000. The SLS AMG is capable of accelerating from 0 to 100 km/h in 3.8 seconds, and can reach top speed of 197 mph (317 km/h). All the other specification in Wikipedia.
