Between the unveiling of the ID. Buzz concept vehicle and the full-production model, which will be with customers this autumn, lie around five years of hard work delivered by the development team of Volkswagen Commercial Vehicles and Volkswagen Passenger Cars. How did the designers actually manage to transfer the basic principle of the legendary original T1 Microbus and the clear contours of the concept vehicle into an all-electric bus and panel van? How in this process were the engineers able to satisfy all the demands in respect of safety, ride comfort and everyday practicality made of a modern electric vehicle? And what did the production and components staff have to get ready in order to incorporate all the parts into the production operation in Hanover, Germany, in such a way that the ID. Buzz is able today to be built along with the other so-called “Bulli” models (T6.1 and Multivan) on one line. A Volkswagen Commercial Vehicles’ TV crew accompanied those involved as they conquered all these challenges and to document their secret work. The result is a comprehensive report, which has been published today
Developing the ID. family’s Microbus and a panel van called equally for cross-brand cooperation and a division of labour: designers and engineers looked for the best possible concept that combined all the requirements of the specification brief. Seven years of Bulli know-how was incorporated into the ID. Buzz, a vehicle designed to thrill both the existing fan community and new customers. And at the same time to be as efficient as possible: the low-friction components of the Modular Electric Drive Kit (MEB) contribute to this, as do good body, underbody and wheel aerodynamics. Following lots of detailed work, the result is outstanding: at just 0.285 the drag coefficient (cd) of the ID. Buzz is lower than that of any other Bulli.
With the first few, hand-built prototypes it can then be decided whether all the design data and simulations from the virtual world can indeed be transferred to the real world. The proof of quality lies in testing. To ensure that also the recently unveiled ID. Buzz fulfils Volkswagen’s highest quality requirements, the electric ‘Bulli’ was put to the test over a complex and gruelling marathon – all over Europe and under extreme conditions. First extremely hot, from very arid to tropically moist. Then extremely cold, from dry to dank. And in many places with no real road surface. Then track testing simulated rain, snow, ice and dusty conditions to see what might penetrate joints in the bodywork and underbody and potentially cause problems there later.
Both equipped with multi-link rear suspension for separating transverse and longitudinal forces, the ID. Buzz and ID. Buzz Cargo demonstrated in the far north of Scandinavia their handling potential on snow and ice. Other aspects examined during the testing at cold temperatures are the design of materials, the electric and electronic functions, the chassis set-up, acceleration, braking and steering at low coefficients of friction and the thermal management of the whole vehicle.
