The German tuning studio Siemoneit Racing presented its development of Seat Leon ST Cupra. Thanks to it, the four-wheel drive vehicle proved to be more powerful than the Mercedes-AMG C63 (476 hp) and the Audi RS4 (450 hp). The first one is with biturbo V8 and the second with biturbo V6 engine.

In turn, the inflated Seat Leon ST Cupra is equipped with a 2.0-liter turbocharger with 4 cylinders, which in its base version develops 300 hp and 380 Nm of torque. The tuning experts have changed the turbine, intercooler, and other major car systems, resulting in the impressive 522 hp. The maximum torque now reaches 620 Nm.

In addition, the wagon has a sports exhaust system, carbon-ceramic brakes from the Audi RS3 and Michelin Sport Pilot Cup 2. The acceleration from 0 to 100 km/h takes longer 3.4 sec, which is 1.8 seconds faster than that of the standard model.

The maximum speed has also increased to 278 km/h, with the removal of electronic limiters reaches even 304 km/h.

So far, the authors of the project do not report how much the car will cost.
