SEAT has released the first official photos of the new Leon ST estate.

The Leon ST (for Sport Tourer) is the first time the Leon range has included a five-door estate model.

SEAT say they’ve worked hard to keep weight in check, and the ST weighs only 45kg more than the five-door, despite being 270mm longer.

Boot capacity is 587 litres with the seats in place, or 1,470 with them folded – 150 litres shy of that offered by the new Golf estate, no doubt as a result of the more rakish styling.

The engine range is the same as that available on the rest of the Leon range, with both petrol and diesel options in capacities ranging from 1.2 to 2.0 litres.

All feature start/stop and energy recovery systems as standard.  The 1.2 TSI 105PS is the most efficient petrol unit, returning 57.6 mpg on the combined cycle, while the 1.4 TSI 140PS isn’t far behind with 53.3 mpg.  The current range-topping petrol unit, the 1.8 TSI, is available only in FR trim and develops 180PS and 250Nm of torque.

The entry-level diesel 1.6 TDI 105PS matches the 1.8 TSI’s 250Nm torque figure, while the larger 2.0 TDI boosts those figures to 150PS and 320Nm, yet returns 68.9 mpg and emits just 106 g/km.

The pick of the range for us, however, is the 2.0 TDI 184PS which boasts 380Nm yet achieves 65.7 mpg.

The Leon ST also marks the debut of a series of new electronic driver and safety aids, including Adaptive Cruise Control, Adaptive Chassis Control and progressive steering, the latter two available as part of a new Dynamic Pack.
