With 300 hp, all-wheel drive and 380 Nm of torque, the SEAT Leon ST Cupra it already offers performances at the level of an Audi S4 Avant. However, the German tuning company Siemoneit Racing felt that the Leon ST Cupra needed a little more lung and so went to work.
The now called Siemoneit Racing SEAT Cupra 300 was the result of this work and offers… 521 hp and 620 Nm of torque!
To get an idea, these values are higher than those presented by the Audi RS4 Avant (450 hp and 600 Nm taken from a V6) and even the Mercedes-AMG C63 Estate has less power (476 hp) gaining only in terms of torque (650 Nm ), this despite having a V8 with twice the size.
To extract all this power from a four-cylinder engine with 2.0 l capacity, Siemoneit Racing installed bigger turbos, new intercoolers, a high-efficiency air filter and several upgrades — fuel pump, aluminum oil pan with more volume , etc…
In addition to the increase in power, the Siemoneit Racing SEAT Cupra 300 also has a reinforced clutch — it maintains the DSG gearbox —, with ceramic brake discs for the Audi RS3 and even a sports exhaust.
More power brings better performance
The result of all these changes is a maximum speed of 280 km/h — without the electronic limits it reaches up to 305 km/h (!) — and a time from 0 to 100 km/h in just 3.4s (against 5.7s for the standard car).

Of course, all these changes come at a price. So, if you want to have a Siemoneit Racing SEAT Cupra 300 get ready to shell out approximately 24,000 euros to add more than 200 hp to the engine — not counting the cost associated with rims, tires (Michelin Sport Pilot Cup 2) and chassis.
If you don't have a SEAT Leon ST Cupra, Siemoneit Racing will charge you approximately 64 000 euros by including the value of the van.
