The “technical, sharp look” was initially the work of Luc Donckerwolke, now head of advanced design for the VW Group, before being further honed by Seat’s current design chief, Alejandro Mesonero-Romanos.
The new five-door Leon is 4263mm long, 1816mm wide and 1459mm high. That’s 52mm shorter, 48mm wider and 4mm higher than the outgoing machine. Its wheelbase is also 58mm longer, at 2636mm.
The use of the MQB underpinnings provides a weight saving of about 90kg compared with the Leon Mk2, which weighed 1250kg in its most basic engine guise and trim level.
The new Leon is to be offered in the UK with a wider choice of engines than the current second-generation version. It will get five petrol options and four diesel variants from the VW Group’s engine range, although not all of them will be available at launch.
The petrol line-up comprises a 1.2 TSI with either 85bhp or 104bhp and a sub-140g/km 1.8 TSI with 178bhp. A 1.4 TSI with either 120bhp or 138bhp will follow. The 138bhp version will have Active Cylinder Technology, which closes down two cylinders during light throttle loads.
The oil-burners in the range are a 1.6 TDI with either 89bhp or 104bhp, and a 2.0 TDI offered in 148bhp or 181bhp states of tune. Seat says the 148bhp version of this engine will emit less than 110g/km and return more than 70mpg. As with the current car, the frugal Ecomotive and sporty FR and Cupra sub-brands will feature in the Leon line-up. The car pictured here is the 148bhp FR variant.
One of the stand-out cars in terms of emissions will be the 104bhp 1.6 TDI, which will return a claimed 73.4mpg and emit 99g/km of CO2.
Transmission options will be either a five- or six-speed manual, or a six- or seven-speed dual clutch gearbox.
Most of the cars in the Leon range feature a MacPherson front axle with a torsion beam at the rear, but the more sporty cars with 148bhp and above have a multi-link suspension at the back.
The Leon FR will get 'Seat Drive Profile', a system that allows the power steering, throttle control and engine sound to be adjusted to one of three modes – eco, comfort and sport. There is also a facility to tailor the settings according to the driver's preference. The interior ambient LED lighting changes according to the selected setting: white in eco and comfort modes and red in sport.
The manufacturer has promised a more premium feel to the cabin, which was criticised for its blandness in the second-generation car. A wide range of Alcantara and leather trim will be offered on higher-spec examples, and improvements in the quality of the materials and of fit and finish are being targeted.
Enhanced multimedia systems and connectivity will also be available. The basis will be the Easy Connect operating system, which controls the hifi and communication functions via a touch-sensitive screen in the cockpit.
The entry trim level features Media System Touch, which incorporates a CD/radio, four speakers and a five-inch touchscreen. Higher-spec variants get Media System Colour, which has a higher-quality touchscreen, CD, six speakers and connectivity for Bluetooth, USB or aux-in.
Above that, Media System Plus includes a 5.8in touchscreen with 3D graphics, iPod connectivity, an optional DAB radio tuner and voice recognition.
The new Leon range will be produced at Seat’s facility in Martorell, Spain, alongside the Ibiza, Exeo and Audi Q3. When the model comes on stream, it will bring the factory close to its 600,000-unit annual capacity.
The new car will be available to order in October with the first deliveries landing in March.
