After it went through a facelift last December, the 2017 Seat Leon Cupra has now fallen into the tuning hands of Je Design.

The aftermarket company has released a 2-stage power upgrade for the Spanish hot hatch, which lifts the stock 300PS (296hp) and 380Nm (280lb-ft) of torque to 360PS (355hp) and 450Nm (332lb-ft) of torque, in the most humble offering.

Stage 2, on the other hand, is more exciting, as it raises the output to 380PS (375hp) and 470Nm (345lb-ft) of torque. This makes it just 20PS (20hp) and 10Nm (7lb-ft) of torque less powerful than one of the compact hot hatch kings, the new Audi RS3 Sportback, which uses a larger 2.5-liter five-cylinder engine, unlike the Leon’s 2.0-liter four-cylinder unit.

Choosing Stage 1 means that top speed will also increase to 265km/h (165mph), while Stage 2 allows the car to reach 280 or 285km/h (174-177mph), by raising the electronic limit.

Making Je Design’s Seat Leon Cupra more sonorous is a stainless steel exhaust, with sound flap system, controlled via the OE Seat driving profile selection system. Customers can choose between four 80mm diameter outlets, or two oval tailpipes of 140×90 or 160x90mm, on each side.

Among the key features added to its exterior are the widened wheel arches, prominent side skirts, new front bumper, gloss black rear diffuser inserts, and adjustable tailgate-mounted spoiler. Je Design has also equipped the Leon with a set of 10×20-inch wheels, wrapped in 265/25 Hankook S1-Evo tires.

Finally, the car has been given a sport spring set, which lowers the ride height by 20mm (0.8in). Owners can also have a KW DDC fully adjustable coilover suspension, which brings the Leon Cupra 45mm (1.8in) closer to the road, compared to the stock model.
