Not too long ago, two automakers joined forces to create a supercar that was part McLaren, part Mercedes: the Mercedes-Benz SLR McLaren. Since then, each company has parted ways and developed their own supercars incorporating their own technology and heritage, the MP4-12C and SLS AMG. They couldn't be more different. It's a story of embracing the future versus embracing the past. A look forward versus a look back. It's chess versus PlayStation. I could go on forever but the point is, the MP4-12C and SLS AMG are two very different supercars built for two different types of people.
