When the Audi E-Tron crossover arrives next year, it will be the first model from the brand to feature an electronic toll payment transponder integrated directly into the rear view mirror. This will be standard for all models and will allow drivers to access select toll roads in the U.S ans Canada, without the need to mount unsightly transponders on the dash or windscreen. The built in module can be controlled directly through Audi's Multi Media Interface system.
