The Mercedes-Benz EQC 4x4 is an electric car of extremes

14 October 2020, 04:28:15

The Mercedes-Benz EQC 4x4 is an electric car of extremesMercedes-Benz showed off the EQC 4x4 - an electric car of extremes. A small team of dedicated developers has created this drivable technology platform on the basis of an EQC 400 4MATIC. The one-off was developed by a cross-departmental team under development engineer Jürgen Eberle which has already put the E 400 All-Terrain 4x4 on its studded wheels. It uses multi-link portal axles as well as the production of a powerful sound in the interior and exterior. The headlamps turn into lampspeakers because they also function as a loudspeaker at the same time.

The Mercedes-Benz EQC 4x4's capabilities include driving through sand in desert regions and on beaches, on rocky terrain, and through mountain streams. As well as great reliability and corresponding comfort, the mature genes of the standard model also allow trailer operation and installation of a roof-rack. A roof-tent and inflatable dinghy allow the remotest areas to be reached – and when making an early start, the other adventurers in the camp will not even be woken up.

At 293 mm, the EQC 4×4 rides more than twice as high as a production EQC (140 mm). Even a G-Class rides 58 mm lower. The fording depth is increased by 15 cm, to 40 cm. The tremendous ground clearance is made possible by the conversion to portal axles: unlike conventional axles, the wheels are not at the height of the axle center but are instead situated much lower down on the axle hubs owing to the portal gears. Or conversely, the entire vehicle moves up. The 4×4 suspension is attached to the same body mounting points as the standard suspension.

Just as impressive are the approach and departure angles - 31.8 degrees at the front and 33 degrees at the rear. By way of comparison, a conventional G-Class has an approach and departure angle of 28 degrees. The reprogrammed Off-Road drive programs take advantage of the high-performance logic of the current GLC models. For example, using targeted brake interventions, this enables an improved torque curve when starting on loose ground. In combination with the tires in size 285/50 R 20, this results in impressive sure-footedness in terrain. The striking visual appearance is rounded off by the matt metallic gun-metal grey car film and the black wheel arch flares.

Another highlight of the EQC 4×4 is the sound experience with its own soundscape. The acoustic production comprises sounds that give the driver feedback on system availability and vehicle parking, as well as an interactive, emotionalizing driving sound. It is influenced by various parameters such as the position of the accelerator pedal, speed or energy recovery rate. The technology uses intelligent sound design algorithms to calculate the sounds coming from the amplifier of the sound system in real-time and the interior loudspeakers to reproduce them.

The production EQC uses the external noise generator (Acoustic Vehicle Alert System, AVAS) required by law to reproduce the sounds. The EQC 4×4 has a more powerful AVAS composed specifically for it and uses the headlamps as external speakers for this purpose. The reason being that the sound experts of Mercedes-Benz have made creative use of the available installation space in the headlamp housings - the "lampspeaker" was born.

The EQC 4×4 is already the third model of the 4×4 family from Mercedes-Benz. The G 500 4×4 was actually built in series production from September 2015. And in 2017, with the E 400 All-Terrain 4×4 study, Mercedes-Benz showed many an SUV its limitations when off-road.
