Did you attend the 2018 Concours d’Elegance? If so, this was probably the first car you saw on the course. The Mercedes-AMG Project One is a plug-in hybrid car that’s based off of its Formula One counterpart, the successful F1 WO7 hybrid. A 1.6 turbocharged V6 engine with 4 electric motors creates 1000+ horsepower and a top speed of 217mph. This is the ultimate limited edition hybrid sports car…and all of them have been sold. Yep, all 275 models have been sold for 2019. Priced around $2.3 million, this is the ultimate Mercedes car.
