Seat introduced the Leon ST X-Perience, a rugged AWD version of its popular estate that will arrive on the market as a 2015MY. As you can see from the photos, the off-road capabilities of the 2015 Seat Leon ST X-Perience are underlined by the new front and rear bumper with protective skid plates as well as by the black plastic design elements that adorn the wheelarches.
In addition, the side sills are also covered in black plastic in order to complete the design. Furthermore, thanks to the improved ground clearance (15 mm) the Leon ST X-Perience offers improved off-road capability.
Under the hood, we will find a choice of three four-cylinder engines: a turbocharged 1.8-liter petrol that delivers 180 PS (132 kW) and 280 Nm (206 lb-ft) of torque; a 2.0-liter TDI diesel engine that delivers 150 PS (110 kW) and 320 Nm (236 lb-ft) of torque or 184 PS (135 kW) and 380 Nm (280 lb-ft) of torque; a 1.6-liter TDI diesel with 110 PS (81 kW) and 250 Nm (184 lb-ft) of torque.
These engines are offered with a standard six-speed manual or an optional six-speed dual clutch automatic (DGS) transmission. Both gearbox options are offered with automatic stop/start and brake energy recuperation functions.
Power is delivered to all four wheels through the latest Haldex multi-plate clutch four-wheel drive system. The 2015 Seat Leon ST X-Perience will make its public debut in October at the 2014 Paris Motor Show.
The permanent all-wheel drive in the all-new Leon X-PERIENCE is among the most advanced and effective systems of its type worldwide. SEAT employs a newly conceived multi-plate clutch with hydraulic actuation and electric controls, a fifth-generation Haldex coupling. It responds very quickly to every imaginable driving scenario, thereby providing a significant increase to the active safety and operations.
In consideration of distributing load to axles, the coupling is at the drive shaft’s end, before the rear-axle differential. Inside is an oil bath with a multi-plate package operating within that. The metal friction rings lie next to each other as pairs. One ring in each set is connected to the clutch basket that spins with the main drive shaft; the other is connected to the drive shaft leading to the rear axle.
In regular drive conditions, the coupling sends most of the engine’s power to the wheels in front. If there is a traction loss, the torque is smoothly redirected to the back in just milliseconds when a piston compresses the plate sets together in a precise way. The new-era coupling no longer needs the prior use of a pressure accumulator, so that it is much more compact and 1.4 kg lighter than the previous component.
Vibrant and Safe on Every Surface - the running gear
The sensibly balanced running gear supports the vibrant personality of the all-new Leon ST. The springs effortlessly control any surface irregularity, while the steering provides smooth and polished directionality, as well as outstanding responsiveness.
