It also means that the new Cupra will leapfrog other upcoming MQB-based alternatives like the new Volkswagen Golf GTI, be it either in standard 217bhp or 'Performance Package' 227bhp form.
To appeal to a wider audience, Seat will offer it in both three and five-door body styles. An estate version may follow, offering an alternative to the Focus ST estate.
In order to boost traction, a neccessity when transmitting 261bhp through the front wheels, the new Cupra will benefit from a mechanical limited-slip differential.
The Cupra's new power figure also represents a significant hike in output over the previous generation, which was powered by a 236bhp, 2.0-litre turbocharged petrol engine.
