Part of the Leon’s advancement is attributable to the platform that underpins it. This is the first Seat to benefit from the Volkswagen Group’s ‘Modularer Querbaukasten’ or MQB platform, the pioneering mechanical component set that makes for unprecedented cost-saving commonality between this car and the Audi A3, Volkswagen Golf and Skoda Octavia.
It isalso being used to form the basis of the VW Group’s next generation of superminis, compact 4x4s and saloons, which has seen the Ateca and Arona built on the same foundations. That’s how the MQB underpinnings have made the Leon’s business case stronger, but it has also had an influence on the new car’s kerb weight and its major dimensions. Weight ranges from 1198kg to 1345kg in the standard hatchback, depending on engine and specification, and from 1189kg to 1350kg in the SC.
A more space-efficient under-bonnet layout has allowed 58mm to be added to the wheelbase at the same time as 52mm being taken out of overall length. The three-door SC shrinks by a further 32mm. In theory, those space-saving measures make for more passenger room as well as better ride and handling.
Sure enough, there are competitive levels of space inside this car, but they’re not outstanding. Practicality is certainly much less likely to sell a Leon than the car’s crisp styling or appealing value for money. The Leon range was facelifted in October 2016, which saw the gain a new grille and redesigned front and rear lights - with the day-running-lights matching the Ateca's signature cluster.
Originally only fives engines were offered but over its time on sale the range swelled to include eight power units across the Leon range. Starting with from a 108bhp, 1.2-litre TSI turbocharged petrol and 1.6-litre TDI, via a pair of 1.4-litre petrols producing 123bhp and 148bhp respectively, followed by the fleet-favouring 148bhp 2.0-litre diesel unit. Heading the range is a 182bhp 2.0-litre diesel engine and an 179bhp 1.8 TSI, both of which are only available on higher spec models.
For those looking for a hot version of the Leon can opt for the Cupra 300, available in SC, 5dr hatch and ST forms, and is fitted with a 2.0-litre TSI petrol engine producing 296bhp.
Powering the Seat Leon 5dr hatch
The eco-focussed 1.6-litre diesel is expected to account for the majority of UK sales, which is a pity because while it’s a workmanlike unit it lacks the punch and flexibility of the market’s best low-emissions diesels. As an entry-level powertrain, the 1.2-litre petrol manual – with its extra intermediate gear ratio – makes a more rounded option.
More credit is due higher up in the engine range. Seat’s 148bhp 2.0-litre TDI makes a strong case, being refined, economical and relatively free-revving. But again, it fails to put much in the way of clear water between it and the equivalent petrol – this time, the 148bhp 1.4-litre TSI. The latter model is cheaper, more responsive, more refined, more flexible and offers marginally better on-paper performance than the diesel, along with fuel economy that’s broadly comparable in everyday use.
The range-topping petrol 1.8-litre TSI with 178bhp is a satisfying unit which is both quick off the line and offers impressive in-gear acceleration. Beware of high-rev rumbles, however, where the engine can sound strained. That said, at cruising speeds it is both refined and quiet. The 182bhp high-output turbodiesel is also impressive. Its 280lb ft of torque feels like a generous slug at medium revs, and the engine is also reasonably happy to rev for one of its type. The 2.0 TSI found in the Cupra models is smooth and free-revving bereft of much drama, but willing to surge forward as the revs continue to build.
Despite Volkswagen’s youthful brand aiming to thrill and entertain drivers all in one, the Leon does suffer in its ride. Eager handling was always more likely to be its forte, and it is, to a point, as long as you go for the right model.
Ordinary S and SE-spec cars come on a standard suspension set-up which, for the majority of models, is fine. It’s got a slightly springier than average balance of compliance and control, but nothing you’d call seriously compromised.
The low-emission 1.6-litre TDI doesn’t quite grip as hard or steer as well as the rest of the range, while Seat's FR-trim sports suspension – an item of equipment to be avoided at all costs in the last Leon – is much more effective this time around. The sports set-up has more fluent and effective damper control to match its slightly firmer springs, and seems much more coherent as a result.
In general, the Leon steers quite well and even with a modicum of feel in some cases, but it could be more positive and incisive. The car benefits from its relatively modest size by feeling agile and wieldy on the road. It isn’t quite as engaging as a well specced Ford Focus or as overtly sporting as an Alfa Romeo Giulietta, but it’s in the same ballpark – and even that is testament to the effort Seat has put into this new generation of Leon.
Choosing the right spec for the Seat Leon
On the equipment front, there are six trims to choose from. The entry-level S models come with a 15in steel wheels, electrically adjustable wing mirrors, central locking, multi collision braking system and halogen daytime running lamps on the outside as standard. inside there's a manually height adjustable driver's seat, air conditioning and Seat's 5.0in touchscreen infotainment system with Bluetooth and USB connectivity.
Upgrading to SE Technology spec adds 16in alloy wheels, front foglights, cruise control, hill start assist, electric windows, front seat lumbar support and an 8.0in touchscreen infotainment system including DAB radio and sat nav, while SE Dynamic Technology adds 17in alloy wheels, tinted rear windows and rear parking sensors.
Mid-range FR Technology Leons are adorned with 17in alloys, a twin exhaust system, LED headlights, a sporty bodykit, sports front seats, dual-zone climate control and smartphone integration, while those choosing the sportier looking FR Titanium Technology gain 18in alloy wheels, a extended rear spoiler and side skirts.
Topping the main range is the Xcellence Technologiy trim, which gives the Leon touches of chrome, ambient LED interior lighting, a leather upholstery, keyless entry and ignition, some additional storage compartments, and the bonus of Seat's Convenience and Winter packs.
Those keen on the aggressive looking Cupra 300 will notice that the Leon comes with 19in alloy wheels, a beefy bodykit, a mechnical limited slip differential, adaptive suspension and an Alcantara upholstery.
Overall, we’d class the Leon as belonging in the chasing pack of family hatchbacks amid the likes of the Hyundai i30, Honda Civic and Kia Cee’d rather than as a challenger to the Volkswagen Golf and Ford Focus at the head of the field. Although the 2016 facelift has moved the Leon closer to the Golf and the Focus than its closest rivals. It’s certainly breaking free, though, and especially in the case of three-door SC models offers more driving enjoyment than in previous generations.
It’s a creditable effort from Seat and a notable improvement in form, with plenty of niche appeal for those who like a dose of style and spirit about their everyday driver but who don’t want to pay a premium.
