Though best-known for its hot Audis, German tuner, Abt Sportsline, has now turned its attention to SEAT's Leon ST Cupra 300 Carbon Edition. Power, torque and loudness all get boosted with a standard 300hp turning into 370hp and 380Nm of torque into 460Nm, mostly thanks to an uprated ECU. Handling is sharpened too, with suspension tweaks. It's not just technical trickery going on here though - outside there are a range of 18- and 20-inch dark-coloured alloy wheels available, complementing the original SEAT's sharp carbon-fibre accents and twin tailpipes. Abt currently offers upgrades for most models in the SEAT Leon range from the lowly 1.4, through the 2.0-litre diesels and on to the sporty Cupra line-up.
