The good-looking new Leon SC makes a rather quiet debut at SEAT’s corner of the 2013 Geneva Motor Show. The new three-door Leon goes on sale later in the year, joining the five-door hatchback and ST Estate versions, offering a sportier alternative to the customers.

The car is based on the five-door Leon, but SEAT says that from A-pillars back it is completely redesigned. The SC features a more steeply raked rear screen, a lower roofline, broad rear shoulders including sharp blisters over the wheel arches, and a new profile for the rear three-quarter windows. It does look quite good in the flesh, at least compared to the other boring family hatchbacks.

The Leon SC should also be a good car to drive, as it is built on Volkswagen Group’s ground-breaking MQB platform that also underpins the latest Golf. It will launch with the same engine and trim range as the five-door, including the 1.6 TDI 105 PS with just 99 g/km CO₂, and later in the year, the rapid-yet-frugal 2.0 TDI 184 PS FR.

At the Geneva Motor Show, SEAT Leon SC is accompanied by the firm’s new Mii Ecofuel, a production car with the lowest CO₂emissions in the company’s history.
