With the web-based e-learning ‘Audi ultra’, innovation mecom has realised a WBT for Audi which proves that efficiency and performance can go hand in hand. As part of the e-learning, the Audi employees learn that Audi ultra is a part of every current Audi product and also that the special Audi ultra models in the product range take the top position in terms of efficiency. Thus, Audi employees can experience efficiency technology from the Audi brand using various exercises. One of the highlights is the efficiency calculator, whereby the consumption and the CO2 emissions of the Audi ultra models can be interactively and intuitively compared to the previous model series. A further highlight exercise is the wind channel developed by innovation mecom, whereby the Audi employees regulate the wind speed and changes in the air resistance are made visible.
