The new ID.4 chassis SUV by Volkswagen
The ID.4 already offers the best prerequisites for a great driving pleasure. The rear-wheel drive ensures strong traction – the driver experiences this already when they arrive at a set of traffic lights in the wet. The high-voltage battery is located between the axles at the lowest point of the car. This benefits the center of gravity and weight distribution: with all drive variants, it deviates from the ideal value by no more than one percent, 50:50.
The front axle of the ID.4 follows the McPherson design, the steering is translated with a 15.9:1 ratio. For the first time at Volkswagen, the steering system is located in front of the center of the wheel, this position guarantees high stability during fast cornering. At the rear is a complex new development – a compact five-link suspension with a subframe that is elastically connected to the body. Parts of the suspension are made of lightweight aluminum to reduce weight.
The range of wheels for the ID.4 starts with the 18- inch format, either in steel or aluminum. Starting with the ID.4 Life model, 19-inch wheels are standard; above that, there are only light-alloy wheels with 20- or 21-inch diameters. Although the large wheels in the wheel arches take up a corresponding amount of space, the ID.4 only requires a turning circle of 10.2 meters – extremely little for a car in its class.
The wheels are aerodynamically optimized by their flat design, the tires have low rolling resistance. In the ID.4 Pure and ID.4 City entry-level models, they are 235 millimeters wide at the front and rear, with cross-sections varying according to wheel size. All other ID.4 models roll off the production line on combination tires – 235 millimeters wide at the front and 255 millimeters at the rear.
The robust E-SUV has powerful brakes – the discs on the front axle of the ID.4 models with the 77-kWh battery are 358 millimeters in diameter. Drum brakes operate on the rear wheels. Their pads are designed to last the lifespan of the car. Corrosion is impossible, although the brakes are rarely used in everyday driving. Most of the deceleration is performed by the electric motor, which recovers energy in the process.
When the driver wants to, the ID.4 takes corners very quickly, stably and almost naturally – also thanks to the electronic Vehicle Dynamics Manager, which works closely with the stability control ESC. Volkswagen has introduced it in the new Golf. The Driving Dynamics Manager controls the wheel- selective brake interventions of the XDS electronic transverse drive lock and the work of the DCC damper control. It uses a digital target model to achieve optimum driving and steering behavior in every situation. As soon as the vehicle turns into a corner, the ID.4 behaves more spontaneously, linearly and accurately.
The ID.4, Volkswagen’s first fully electric SUV and the brand’s first electric world car, will be launched after the 1ST Edition with eight preconfigured models. The high-voltage battery is available with 52 or 77 kWh energy capacity (net), the range is up to 520 kilometers (WLTP). The electric motor is available in three power levels between 109 kW (148 PS) and 150 kW (204 PS).
As part of the “Transform 2025+” strategy, the Volkswagen brand is investing eleven billion euros in electromobility by 2024. The ID.4 is the second model of the ID. family following the ID.3. This new product line has recently been added to the brand’s traditional portfolio. The term ID. stands for intelligent design, identity and visionary technologies.
