SEAT launches range-topping Leon 15 June 2010 by Parkers Most powerful SEAT ever built 265bhp turbocharged engine On sale now, priced at £25,205 SEAT has revealed details of its most powerful car ever - the Leon Cupra R. The new model is on sale now, priced at £25,505, and offers 265bhp from its turbocharged 2.0-litre petrol engine. This is enough for a top speed of 155mph while 0-62mph acceleration takes just 6.2 seconds. But just as impressive is the car's economy - SEAT claims a combined figure of nearly 35mpg while CO2 emissions are 190g/km. The latter figure puts the Leon in the 27% benefit-in-kind tax band. Compared to its key rival, Volkswagen's £30,930 Golf R, the Leon offers more power, lower emissions and a cheaper price, making it one of the most affordable super-hatches on offer. As well as an uprated engine, the Leon Cupra R gains a short-shift gearbox and a system called XDS which combines the ABS brakes, ESP stability control, TCS traction control and EBA emergency braking assistance. Together, these systems work to channel the Leon's power through the front wheels and cut down on torque steer. To mark out the Cupra R from lesser versions, it gains twin central exit exhaust pipes, 19-uinch alloy wheels, rear diffuser, spoiler and gloss black highlighting on the outer trim. The Leon Cupra R is available now, priced at £25,205.
