The Mercedes AMG One was recently caught, blasting down the Nurburgring. The hyper-hybrid was supposed to be on sale from 2019, but it was delayed. The camouflaged version spotted at the Green Hell is proof that the people from AMG are using the extra time to refine the car even further. With this in mind, the Mercedes AMG One is expected to be on sale sometime later this year. The car will be produced in a limited run of 275 units, all of which have already been sold, at a sticker price of $2.72 million each.
