In the latest series of Audi\u2019s tech talk, we get to learn about the electric Quattro system that\u2019s featured in all Audi e-tron models.<\/p>\n

Traditionally, Audi\u2019s Quattro system has relied on a centrally-located Torsen differential that routes power to the front and rear axles, based on available grip. It started out as a viscous coupling diff, which would clutch-up and send power to the opposite axle of one that was spinning. So if the rear wheels were spinning too quickly, that would cause the diff to send more power to the front axle. While that\u2019s extremely effective, and modern systems have become far more advanced, Audi\u2019s new electric Quattro system is far faster to react and far more controllable.<\/p>\n

\u201cFor us, the electric Quattro is the perfect combination of powerful performance and high efficiency,\u201d says Michael Wein, Project Leader All-Wheel Drive Control Systems. \u201cWe combine the efficiency advantages of a driven axle with the traction and dynamic performance of an all-wheel drive system.\u201d<\/p>\n

\"\"<\/a><\/p>\n

Under normal driving circumstances, in all Audi e-tron and e-tron S models, only the rear axle is engaged, while the front axle just chills out, for efficiency purposes. However, as soon as added grip and power from the front axle is need, for either performance driving or low-traction circumstances, both axles are engaged. More than that, the exact amount of power from the front axle is used, for not only efficiency but also for precision.<\/p>\n

It\u2019s also far quicker than any mechanical all-wheel drive system to respond. In fact, the car\u2019s systems can monitor wheel spin and\/or traction losses, assess how much front axle traction is necessary and then engage said front axle all in under thirty milliseconds. On average, that\u2019s four times faster than a mechanical all-wheel drive system can respond.<\/p>\n

Admittedly, this isn\u2019t unusual in electric cars. In fact, all electric cars use similar setups. However, Audi\u2019s expertise in the world of performance all-wheel drive does give the brand an advantage in tuning the system. For instance, it can use a combination of driven electric axles, regenerative braking and brake-torque-vectoring to reduce understeer as much as possible, provide the most traction available and even make the car more fun and engaging to drive.<\/p>\n

In the case of Audi e-tron S models, which boast three electric motors \u2014 two at the rear and one at the front \u2014 the system can actually vary torque between the rear axles far quicker than a traditional differential. Not only is it faster in its response but it\u2019s also more precise, providing the exact amount of power to each rear wheels for the best possible performance.<\/p>\n

For anyone that thinks Audi\u2019s Quattro performance will die off as electrification becomes more prominent, it\u2019s actually the opposite that\u2019s true. Electrification allows Audi to actually increase its all-wheel drive performance potential and it allows Audi Sport to utilize its decades of all-wheel drive expertise in an even greater manner.<\/p>\n
