Mercedes presents the 2020 EQC 4×4² Concept for rough terrain.
A team of Mercedes’s designers has developed a drivable technology platform on the basis of an EQC 400 4MATIC. They want to show it is possible to combine love of adventure with lifestyle and sustainability, and to prove that e-mobility can be not only urban, but also conceivable off-road.
The Mercedes-Benz EQC 4×4² is the third model of the brand’s 4×4² family. It has joined to the G 500 4×4² and the E 400 All-Terrain 4×4².
The EQC 4×4² Concept’s technical highlights include the multi-link portal axles, the headlamps turned into “lampspeakers”, a 4×4² suspension.
The vehicle is around 200 mm higher than the standard version. It is capable to drive through sand in desert regions and on beaches, on rocky terrain and through mountain streams. The model also allows trailer operation and installation of a roof-rack.
At 293 mm, the EQC 4×4² rides more than twice as high as a production EQC (140 mm). Even a G-Class rides 58 mm lower. The fording depth is enlarged by 150 mm to 400 mm.
The enormous ground clearance is made possible by the conversion to portal axles. Thanks to the modern axle kinematics with four-link front axle, the turning circle is small, despite 20-inch wheels.
Besides, Mercedes reprogramed the off-road drive programs to improve torque curve when starting on loose ground, and achieve impressive sure-footedness in terrain.
Other ‘off-road ‘goodies’ include 285/50 R 20 tires, matt metallic gun-metal grey car film, black wheel arch flares measuring 100 mm.
The EQC 4×4² key off-road data:
- Approach angle 31.8 degrees (20.6)
- Departure angle 33 degrees (20)
- Breakover angle 24.2 degrees (11.6)
- Ground clearance 293 mm (140)
- Fording depth 400 mm (250)
In brackets there are the standard EQC 400 4MATIC’s data to compare with the EQC 4×4².
Unique Sound Experience
The EQC 4×4² has its own soundscape. The acoustics comprises sounds that give the driver feedback on system availability and vehicle parking, as well as interactive, emotionalizing driving sound. Various parameters (the accelerator pedal position, speed and energy recovery rates) influence this.
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.
Compared with the Acoustic Vehicle Alert System in the production EQC, the EQC 4×4² has a more powerful AVAS. It uses the headlamp housings as external speakers (“lampspeakers”).
