The UK’s Autocar reports that Audi will put a four-wheel-drive electric sedan rivaling the Tesla Model S into production. Perhaps to be called the A9 e-tron, the car will share much of its technology with the upcoming e-tron quattro SUV, including the advanced torque vectoring capabilities. (Earlier post).
Audi R&D boss Stefan Knirsch said he is confident the new electric saloon will deliver a unique driving experience through the use of electric motors and a power electronics package that Audi is developing.
Knirsch said: “Some rivals have gone for a synchronous motor with a high power density but at relatively low revs. There are also asynchronous motors that typically achieve similar power outputs but at much higher revs. From 2018, our electric cars will be equipped with asynchronous motors. We are convinced they offer higher efficiency levels than synchronous motors.”
