11. Mercedes R63 AMG
With each new product, AMG seems to set the limits further. Ever since Mercedes fully acquired it in 2005, they’ve wanted to use the name and performance expertise on basically all models. So, car enthusiasts got the R63 AMG.
If you are not familiar with the R-Class, it is a big minivan based on the S-Class sedan, equipped with all conceivable luxuries and powerful engines. It is perfect for crossing continents in the comfort of a leather sofa traveling at 100 mph. However, AMG had something to say about that. They introduced the R63 with a fantastic 6.2-liter naturally-aspirated V8 and 503 HP.
With a stiffer suspension, tons of power and great performance, the R63 was no ordinary minivan but a sports car with room for seven people. This was the perfect example of a glorious engine AMG installed in a car that was not adequate, but the R63 simply didn’t grab the market.
