Elsewhere in Europe, the Italian Pagani Huayra R awaits. Needless to say, a hypercar is the kind of vehicle that’s going to need a special powertrain behind it, and with the Huayra, only a very specialized engine will do: the V12 R. The Huayra R was launched in 2021, equipped with a 6-liter V12 engine created by HWA (Mercedes-Benz’s racing subsidiary). This is an exclusive engine for the model, and very exclusive it is too: just 30 Huayra Rs were made.

The engine sports 838 horsepower, which may sound ever so slightly — if the word may even be used in reference to the Huayra R — modest, compared to some of the ludicrous creations on this list, but its performance is no joke. Naturally aspirated, unlike its twin-turbo predecessors, it can achieve speeds of 200 mph according to a 2023 Autocar review. Was that enough for Pagani, though? It was not. There was more to be coaxed from the Huayra family yet, in the shape of the R Evo. 
This model, Pagani reported in February 2024, features an “upgraded and enhanced V12-R Evo engine,” with its output increased to 900 horsepower. This, in turn, affords it an increased top speed of 218 mph. The open-top style was implemented not solely for the aesthetic, but it also makes the model even more aerodynamic: “there is an incredible 45% increase in downforce and a 21% increase in aerodynamic efficiency with the same resistance,” the brand noted.
