What is the difference between the Audi R8 RWS and Quattro models?

I'm in the market for an Audi R8 and I've noticed there are two different models listed - the R8 RWS and the R8 Quattro. Can someone explain the differences between the two?

The main difference between the Audi R8 RWS and Quattro models is the drivetrain. The RWS (Rear Wheel Series) is a rear-wheel drive vehicle, while the Quattro is an all-wheel drive. This means that the RWS will offer a more sporty, agile driving experience, while the Quattro will provide better traction and handling in various road conditions.

Another important difference is the weight distribution. The R8 RWS has a rear-biased weight distribution, making it more responsive and dynamic on the road. The Quattro, on the other hand, has a more balanced weight distribution thanks to its all-wheel drive system, which can provide additional stability and control.
