What is the difference between horsepower and kilowatts in the Audi e-Tron?

I have heard that the Audi e-Tron has electric power instead of a traditional combustion engine. How does this affect the horsepower and kilowatts of the vehicle?

The Audi e-Tron has a unique powertrain that utilizes a front and rear electric motor to provide 355 horsepower and 414 pound-feet of torque. This translates to around 265 kilowatts of power, giving the e-Tron impressive acceleration and an impressive range.

While traditional cars use horsepower to measure engine power, electric vehicles like the Audi e-Tron use kilowatts. Kilowatts are a unit of measurement for electrical power, and the motors in the e-Tron produce about 265 kW combined.
