Virtual rear view mirrors reduce the overall width of the model is 15 cm, to reduce wind resistance and noise.
Immediately explain the title: cameras instead of exterior mirrors (not in addition to the normal and independent) is very common on concept cars. You may recall the small-scale model called Volkswagen XL1 was released in an edition of 250 copies, also with cameras. Mass cars no one such “mirror” did not put. The Germans assure that would be the first electric SUV Audi e-tron. The “-tron” by default, exterior mirrors — classic, but in the option they can be replaced with “chamber”.
The premiere of the production of electric cars will take place in August at the Brussels motor show.
Legislators in a number of countries (starting with Japan) either have already allowed the camera-mirrors in production cars, or are preparing for such a move. Goes, behind Audi we are likely to see a wave of such models. Camera output image to the display type OLED (organic LEDs), located between the door and front panel. Through the MMI settings cameras possible to change, based on the conditions (modes “Highway”, “Turn” and “Parking”).
The reserve, the developers promise “more than 400 km in the cycle WLTP”. On the highway you can pass and 500. It is on track, good aerodynamics is “at hand”, but in the other modes of it is good. No aerodynamic tricks run on the WLTP would be below 35 km, according to the manufacturer.
Virtual mirror helped to reduce the coefficient of air resistance to 0.28. Crossover is a phenomenal figure. The most modern models, it is equal to 0.3-0.35 and only in rare cases is lower (i.e. better): 0,29 from Jaguar I-Pace and 0.24 Tesla Model X (both, tellingly, electric cars). Thanks for such a result is possible and a solid body style “throne”, and a lot of subtle but important details. For example, virtually flat bottom, covered with panels in the front, in the center (there is durable protection of the battery) and back. In places of fastening panels have a small notch, further reducing drag. In addition, at speeds above 120 km/h adaptive air suspension lowers the body by 26 mm, which also contributes to aerodynamics.
Behind the grille are two electronically controlled dampers that can open and close independently from each other, optimizing the penetration of the air inside depending on the needs of the power electronics and electric motors for refrigeration.
Air intakes in the front bumper and the ducts behind them down the stream to the wheel arches in such a way as to reduce turbulence. Even the rims have been designed from the point of view of aerodynamics. The Germans thought about such things as inscriptions on the sidewalls of the regular tires (the dimensionality of 255/55 R19). Letters made not prominent, but depressed. The tyres themselves — with very low rolling resistance. And this is another contribution to the overall energy savings.
