New Seat LEON FR 2020 Test Drive Review POV.

The all-new SEAT Leon lights the way in the segment

The fourth-generation SEAT Leon is the most advanced vehicle in the history of the brand. This also translates to its cutting-edge illumination technology, bringing LEDs to a level of sophistication and efficiency that were previously unknown. In this model, the halogen lighting completely disappears.

The all-new SEAT Leon offers two levels of front illumination. The standard LED in the Reference and Style trims uses four diodes per headlight and offers 550 lumens (luminous flux on the road, low beam). Standard in the Xcellence and FR trims, the SEAT Leon uses Full LED dynamic headlights, with up to 900 lumens and 11 light-emitting diodes per module, which provides illumination with greater intensity and accuracy without dazzling other vehicles.

The LED illumination offers greater light output, greater possibilities of where, when and how to aim the beam of light, lower consumption and higher durability. Another contribution to better safety at the wheel is the quick reaction time. An LED diode responds 150 milliseconds faster than an incandescent lamp, which, when driving at 120 km/h, allows the driver behind to see our brake lights five metres earlier. Even the indicators on the mirrors allow, thanks to their sequential mode, other rode users to see which way the Leon is going to turn with greater clarity.

LED technology also permits more freedom in the design. The rear of the new SEAT Leon offers, in the Xcellence and FR versions, functional illumination that connects the lighting groups across the width of the body, called "coast to coast".

However, the concept of illumination in the new SEAT Leon goes much further. The greeting "Hola!" is projected on the ground when the doors are opened, welcoming the user to the car. Once inside, the wraparound ambient lighting allows the user to vary both the intensity and the tone of the illumination. Created in the form of an arc from the front doors to the top of the dashboard, this ambient lighting surrounds the passengers and accentuates the sensation of space. The interior illumination was not only conceived to increase the comfort of the occupants and to provide a more sophisticated design, but it also delivers an important safety function with the safe exit assist. This system, through light and sound alerts, notifies the passengers if a vehicle is approaching from behind when they open a door.

On the other hand, the lighting groups are a fundamental piece in the design of a vehicle and one of the elements that bring the most personality to it. Illumination technology has advanced greatly in the last two decades, with the introduction of xenon headlights, LED lights and assist and dynamic illumination systems. Born in 1999, the SEAT Leon has been adding all these technologies in a process of constant updates. In its latest version, it has taken illumination technology to the highest level.

Since the first generation, the SEAT Leon has stood out in the field of illumination, both for its design and for its lighting capacity. The first Leon was already ahead of its time, with powerful halogen headlights in a teardrop shape and prominent rear lights that ran from the rear spoiler across most of the boot. For lighting both on the exterior and inside the cabin, filament bulbs were used, although for the low and high beams halogen bulbs were used; an evolution from the incandescent bulbs in an inert gas atmosphere with tungsten filament and a small amount of a halogen, such as iodine or bromine. The halogen headlights with H7 bulbs provided up to 450 lumens of intensity (luminous flux on the road; low beam) and a light colour temperature of 3,200 Kelvin (slightly whiter warm light), with a consumption of 55 watts in the low beam.

The fog lights were standard, and the driver could regulate the height of the beam using a control button, in order to avoid dazzling other road users and allowing the greatest reach possible, regardless of the load in the vehicle.

Between 2005 and 2012, the SEAT Leon started to introduce new illumination technologies in a constant process of evolution and improvement. Since its release, it has allowed customers, for the first time, to choose between halogen or bi-xenon technology for their headlights, with gas discharge lamps for both low and high beams. This technology offers greater luminosity, (850 lumens compared to 500 with halogen), consumption that is 35% lower and a longer life. Also, the whiter colour, with a temperature of 4,000 Kelvin degrees, reduces eye fatigue for long journeys at night.

The technology includes a device that automatically and dynamically regulates the headlights. Using two sensors and an electronic control unit, the position of the beam of light is automatically adjusted depending on the load, the acceleration and braking, which increases safety and avoids dazzling others.
