An automobile like this hasn't been seen since the 1960s, but Mercedes Benz intends to bring the hiatus to an end with its upcoming SL Gullwing supercar. While it is still in the planning stage, rumor has it that the supercar will be powered by a twin turbo AMG V8. The 6.3 liter engine will put out about 750 hp and will quickly make up for time lost over the past 40 years. Stay tuned, as we'll keep you posted if any more snippets are released about this sweet MB.
