SEAT has moved away from the sharp edges of the previous generation Leon for a slightly softer look.

The headlights, one of the distinctive elements of the MK3 (the first in its segment to have full LED lighting) have been narrowed, like on the Tarraco giving the car’s “eyes” a slightly more aggressive look.

The all-new SEAT Leon uses the latest in lighting technology both in the cabin and around the exterior of the vehicle to accentuate its dynamic styling and bring focus to the overall design.

New SEAT Leon Lighting detail video

The full LED technology used in the headlights makes even the darkest road visible to the driver and incorporates SEAT’s distinctive daytime running light signature to mark it out as one of the family.

The cold white light colour of the LEDs provide an unmatched luminosity of up to 900 lumens, (the standard LEDS provide up to 550 lumens) thanks to the 22 LEDs per module, and integrate all the critical functions: dipped beam, high beam and daytime running lights. The vehicle’s side mirrors also include integrated LED indicators.


The world is more digitalised than ever before and the all-new SEAT Leon has been future-proofed – developed as the brand’s first fully connected car, it will keep the driver and its occupants connected to the car and the outside world like never before.

At the heart of the Leon’s infotainment system is the SEAT Digital Cockpit, which brings together a high-resolution 10.25-inch fully-customisable driver instrument cluster and infotainment system. The standard media system features an 8.25-inch screen with smartphone audio compatibility. The larger 10-inch screen Navi system (SE Dynamic upwards) offers Online Connectivity, 3D connected navigation, Retina display capability and natural voice control as well as gesture recognition to simplify user interaction.

In the all-new Leon, a new voice recognition system enables a natural understanding of language in order to allow the user to interact with the infotainment system using natural commands, making corrections and referencing previous commands. It is also possible to download and integrate smart services, which will connect with your account and means you will always stay in touch with your smart appliances.

With the Full Link system, customers are able to seamlessly connect their smartphones and access their digital lives no matter what device they use – either wireless Apple CarPlay (based on Bluetooth or WLAN) or Android Auto using a cabled connection.

The Full Link system is the gateway to connectivity, allowing users to connect their mobile devices to the vehicle’s infotainment system and access to get directions (via Apple Maps), make calls with access to your full contact list, send and receive messages, and listen to your music playlists. Full Link can be accessed via the infotainment system or the multifunction steering wheel.

Leon is also now available with wireless phone charging within the lower centre console, to ensure your (compatible) device remains charged ready for the next part of your journey.

Online Connectivity via the embedded SIM (eSIM) means that the all-new SEAT Leon will never lose its connection to the digital world and allows users access to the latest infotainment apps, as well as be able to offer new digital products and services throughout its lifetime.

The built-in eSIM delivers the eCall service, which directly contacts emergency services should an incident occur, adding yet another level of safety to the vehicle. If an eCall is triggered, vital data is sent to the emergency services also, including position (based on GPS data), engine type, and number of passengers, making it easier for them to assist.

Online Connectivity also allows some infotainment functions to use real-time information from the cloud, enhancing the traditional navigation system. Real-time traffic information will re-route the navigation if there is an incident ahead, as well as informing the driver of the location, opening times and current prices of both car parks and fuel stations. For those who don’t want to be limited to the radio they listen to, new Leon adds online radio into the cabin, allowing the customer to listen to any online radio station they choose, even if it’s from a different country.

The all-new SEAT Leon also features Car2X connectivity – a cloud-based technology that enables drivers to receive an advanced warning on the status of upcoming traffic lights or an incident on a motorway further up the road, with traffic information appearing in real-time on screen.


The next level of connectivity is being made available to Leon customers with the introduction of the SEAT Connect app.

From the SEAT Connect app, users can remotely access driving data of previous journeys and remaining range, parking position, lock and unlock the doors, set up speed alerts so you can be warned if someone using your vehicles is driving too fast, be alerted if your vehicle has been stolen, or activate the horn and turn signals to find the car more easily in a crowded car park.

In Plug-in Hybrid variants, the driver can review and manage the charging process via the e-Manager, prepare the cabin for a journey by controlling the electronic air conditioning, as well as manage departure times all from the smartphone app.


The all-new SEAT Leon has a range of powertrains that now also includes electrified variants to boost efficiency. The new-generation car is available in petrol (TSI), diesel (TDI), mild-hybrid (eTSI) and plug-in hybrid (eHybrid) units.

The engines can be mated to a six-speed manual or a seven-speed DSG (direct shift gearbox) transmission.

Models that use the DSG automatic transmission now benefit from shift-by-wire technology. The system is designed so that the gear selector is no longer mechanically connected to the gearbox, instead using electronic signals to indicate a shift.

In FR and FR Sport models, in addition to the driving mode presets – Eco, Normal and Sport – drivers can use a sliding scale of changes to adapt the all-new SEAT Leon to their exact requirements.

SEAT Leon Magnetic Tech

Petrol (TSI)

The new Leon’s petrol engines are all direct-injection, turbocharged units and provide power outputs between 110PS and 190PS.

For the first time, Leon is available with a 1.0-litre three-cylinder 110PS TSI engine and six-speed manual.

Also available, as a 130PS and 150PS output, is the larger 1.5-litre TSI four-cylinder unit – mated to a six-speed manual – which enhances performance without impacting efficiency.

Both engines use a Miller-cycle combustion process and variable geometry turbocharger to ensure performance and efficiency , as does the integrated Active Cylinder Management. The Miller-cycle optimises valvetrain control with early closure of the inlets which, combined with a higher compression rate and turbocharging, better control the air-fuel mixture and improve fuel efficiency by up to 10 per cent.

A 190PS 2.0-litre TSI unit linked to the dual-clutch seven-speed DSG transmission is also available.

Diesel (TDI)

The all-new SEAT Leon benefits from two diesel powertrain options, both 2.0 litre TDI units.

Both the five-door and Estate variants are available with either outputs of 115PS or 150PS and a six-speed manual transmission.

The diesel engine introduces a new Selective Catalytic Reduction system that includes dual AdBlue injectors to significantly reduce NOx emissions compared to previous generation diesel engines. The result is a range of diesel engines that meet the strict requirement of the latest emissions standards.

Mild Hybrid (eTSI)

The all-new SEAT Leon can also be specified with mild hybrid technology (eTSI), further enhancing efficiency. The system, which is available with the 1.0 TSI 110PS and the 1.5 litre TSI 150PS petrol units, mates 48-volt mild-hybrid technology to the combustion engine.

The technology uses a 48V starter-generator and lithium-ion battery enabling the vehicle to coast (no pedal input from the driver) with the engine switched off (while retaining all key electric functions, such as power steering), harvest energy under deceleration and provide electrical torque assistance during acceleration.

Plug-in Hybrid (eHybrid)

SEAT will also expand its line-up of electrified vehicles with a plug-in hybrid electric version of the Leon. A 1.4-litre TSI petrol engine electric motor, 13kWh lithium-ion battery pack and six-speed DSG transmission combine to produce 150kW/204PS of power and is recharged via a 3.6kW AC inlet. New Leon can be fully charged from 0% in less than 3.5 hours.

The plug-in hybrid version also allows users to driver Leon via electric power only, emitting no emissions and giving a usable range of 60km (38 miles) – perfect for cities where air quality regulations are stricter.

The plug-in hybrid version will be offered on both the five-door and Estate models.

The all-new SEAT Leon is the safest vehicle the brand has ever developed; designed to see more of its surroundings and react to obstacles on the road or sudden movements by other drivers thanks to the integration of a suite of updated and completely new advanced driver assistance systems (ADAS).

“The all-new SEAT Leon has been designed and developed to be the most innovative product the brand ever made – besides its online connectivity it also offers state-of-the-art driving assistance systems. It inspires passion and awakens something inside people when they look at it, you just have to watch and let the vehicle convey its essence,” said Axel Andorff, Executive Vice-president for Research and Development at SEAT. “It is all about touching and feeling the new Leon.”

The new ADAS technologies continually sense the environment to offer the optimum protection no matter what scenario occurs when you’re behind the wheel.

The all-new SEAT Leon brings together predictive Adaptive Cruise Control (ACC) and Emergency Assist 3.0 to protect the vehicle and its occupants while driving or stationary.

Predictive Adaptive Cruise Control (ACC) uses feeds from GPS data delivered from the navigation system and input from the front-mounted camera and Traffic Sign Recognition, allowing it to proactively amend the cruise speed depending on the road layout ahead – bends, roundabouts, junctions, changes in speed limits and built-up areas. This reduces the requirement for driver input and mitigates against sudden speed changes and manoeuvres.

To maintain safety and meet legal requirements, the driver must continually monitor the system and their surroundings, keeping at least one hand on the steering wheel. If the vehicle senses that the driver has taken both hands off the wheel for more than 15 seconds, they will receive audible and visual warnings. A braking jolt can be given. If the driver continues to fail to respond, the Emergency Assist 3.0 system can bring the Leon to a complete stop.

The all-new Leon enters production in January 2020.

* FR Sport, Xcellence and Xcellence Lux will be available to order in Q2 2020

I hung onto my Mk1 because I didn't like the look of the Mk2. I thought the Mk3 looked better, but not enough to make me buy one - I hate broken swage lines. I saved up enough to buy a new one when the Mk4 came in. Guess what? Yes, I'm still keeping my Mk1 LCR.

I really think that the vehicle needs to be seen in person to fully get the true look. I can see most of the points made on forum based on the images but I think many will be swayed once the see it in the metal. I have seen it a few times in the flesh now and I think it is nice but will take time to gain acceptance in the fan base community.
