I agree FI is the cheapest way to make a motor fast. Definitely not debating that, it's ingenious and it works. However, there are companies like BMW that do all kinds of excellent R&D work to make engines that are 100hp per litre without FI. Whereas MB has an AMG division that puts a SC on it and then bumps up the price what, $30k? For $1mil I would expect some R&D. Edit: P.S. I don't take offense to your input, you are countering my opinions with calculations lol
