Volkswagen is showing in Detroit how multifaceted electric mobility can be with the I.D. BUZZ concept vehicle—maximum space utilization with all-wheel drive, electric motors at the front and rear axles, a fully autonomous driving mode (“I.D. Pilot”) and a new generation of display elements and controls.
“The I.D. BUZZ is a next-generation vehicle based on the new Modular Electric Drive Kit (MEB), offering comfort and plenty of space,” says Dr. Frank Welsch, Volkswagen Member of the Board of Management responsible for Development. “The overall concept of the I.D. BUZZ points the way to the future. This concept vehicle is the world’s first electric multi-purpose vehicle to be equipped with a fully autonomous driving mode. It carries the feeling of freedom of the Microbus over to a completely new era of mobility.”
The zero-emissions all-wheel drive system has a total output of 369 horsepower and an NEDC electric driving range of 600 kilometers (270 miles on a predicted U.S. driving cycle). One electric motor at the front axle and one at the rear each deliver a power output of 201 hp, distributed between the two axles by an “electric propshaft.” The I.D. BUZZ shown in Detroit can accelerate from 0 to 60 mph in about 5 seconds, with a governed top speed of 99 mph.
The vehicle’s 111 kWh battery can be charged to 80 percent of its capacity within 30 minutes using the Combined Charging System (CCS) or an inductive charging interface, with a charging rate of 150 kW. As an alternative, the battery can be charged from any conventional household outlet and at charging stations. The all-wheel drive configuration is just one of several that are conceivable. Thanks to the MEB, it would be just as easy to equip the I.D. BUZZ with a rear-wheel drive setup producing up to 268 hp and a smaller 83 kWh battery, depending on the region and purpose of use.
The I.D. BUZZ is fully autonomous multi-purpose vehicle. A push on the steering wheel makes it retract and merge into the instrument panel, switching the I.D. BUZZ from manual control to the fully autonomous “I.D. Pilot” mode that could make it into production by 2025. In this mode, the wheel is decoupled from the steering gear via a newly developed steering column system. The ambient lighting then switches from white light (“Drive”) to mood lighting that is warm and relaxed. At the same time, the distribution of ambient lighting is extended to the rear seating area. Simultaneously, the status of the I.D. BUZZ can be seen at all times on the tablet and the augmented reality head-up display.
Now driving on its own, the zero-emissions concept has already activated its on board laser scanners. Four of them extend from the roof in “I.D. Pilot” mode. The cleanly styled roof sensors call attention to the fully autonomous mode by indirect lighting.
The I.D. BUZZ is not only able to detect other road users with its laser sensors, but also with the assistance of ultrasonic sensors, radar sensors, side area view cameras and a front camera. Traffic data is also continually acquired and compared with the vehicle data via the cloud. Fully autonomous mode is deactivated by touching the steering wheel or by pressing the brake or accelerator pedal.
I.D. knows who will be at the wheel, thanks to the Volkswagen User-ID. This is an individual profile that stores the personal seat and air conditioning settings, favorite radio stations and songs, sound system settings, exterior sound, configuration of the navigation system, type of ambient lighting and contact information for the driver’s friends and business associates. This profile can be retrieved securely via the cloud.
Consequently, the I.D. BUZZ also recognizes which person is entering the car or wants to take the steering wheel at any given time via the authorized user’s smartphone—the Digital Key. As soon as a person approaches the vehicle, the sensor surfaces for opening the Door light up. If the person’s hand is very close to the surface, that individual door is opened. Using the Volkswagen User-ID and a relevant smartphone app, passengers in the vehicle can also control infotainment functions and input intermediate destinations into the navigation system. The route is shown on a tablet.
The I.D. BUZZ communicates with its surroundings via the LED lighting at the front end. The LED headlights interactively mimic the gestures of the human eye and thus interact with other traffic. The concept vehicle masters these light scenarios: Parking, Opening, Driving, Automated.
There are no rearview mirrors in the I.D. BUZZ. Cameras and a display have taken over that function. Where there would normally be a rearview mirror, there is a screen called the e-Mirror. Here, a monitor combines data from the exterior mirror cameras on the left and right of the vehicle and from a camera that faces directly rearward. Doing away with the side mirrors improves the aerodynamics of the vehicle.
The lighting mood of the interior also changes according to the mode. In “Drive”, illuminated elements are lit in white. When the driver activates “I.D. Pilot”, they switch over to a warm mood color. In addition, the ambient lighting and touch-sensitive steering wheel assume warning and indicator functionality. In “Drive” mode, if the driver wants to change lanes while another vehicle is alongside, a warning signal is shown on the relevant side of the dashpad. This means that the LED warning indicators for the Blind Spot Monitor, which are located in the DOOR mirrors in today’s vehicles, migrate into the interior where they are even more obvious to the driver.
