Audi's e-Tron Sportback features brake-by-wire. What is brake-by-wire, and is it safe? In this video we'll look at the technology and engineering involved with brake-by-wire, talk about why it's done, what benefits it has, and what failsafes exists in case of emergency situations. Brake-by-wire ultimately uses electronic control of the disc brakes. But if things go wrong, there's still a way to stop the car. Check out the video to learn all about it!

From Audi's Press Release:
"New for model year 2021, the Audi e-tron model lines receive impressive revised packaging, including attractive entry pricing with a new Premium trim level. As a result, the e-tron SUV is offered at $65,900 starting MSRP for the model year 2021, a decrease of close to $9,000 from the starting MSRP of the model year 2019 Premium Plus e-tron. The e-tron lineup also receives a number of technical spec enhancements for improved utility. Through optimized drive system hardware and software adjustments, the 2021 e-tron achieves efficiency improvements resulting in an EPA-estimated range of 222 miles, an increase of 18 miles. Meanwhile, the e-tron Sportback delivers an EPA-estimated range of 218 miles.

As technology progresses, the e-tron lineup has seen its most significant improvements with available battery capacity and efficiency. For a more efficient configuration, thanks to a number of optimizations, the front electric motor is able to be entirely disengaged, dramatically reducing power usage when not needed. Only when the driver demands more power or traction do both motors spring into action, providing the surefootedness of Audi quattro® technology and the powerful dynamics Audi is known for.

In addition, the usable amount of the high-voltage battery has increased for the model year 2021 e-tron lineup. The battery in the Audi e-tron and e-tron Sportback have a total capacity of 95 kWh and now gives customers access to a net energy figure of 86.5 kWh— almost 3 kWh more than 2019 e-tron model. The energy buffer is designed to help ensure customers enjoy sustained battery performance throughout the life of the vehicle.

Enhancing the charging experience are dual charge ports on the driver and passenger side of the vehicles, newly available on the Premium Plus trims of the e-tron and e-tron Sportback."
