What are the key differences between the Audi R8 V8 and V10 models?

I'm considering purchasing an Audi R8 but can't decide between the V8 and V10 options. Can someone explain the main technical differences between the two models?

The V8 and V10 models of the Audi R8 have significant differences in engine size and power output. The V8 model has a 4.2 liter engine producing 430 horsepower, while the V10 model has a 5.2 liter engine producing 540 horsepower. This leads to a noticeable difference in acceleration and top speed.

One key difference between the V8 and V10 models of the Audi R8 is the exhaust note. The V10 model has a more aggressive and throaty sound, while the V8 model has a smoother and more refined sound. This can be a major factor for some buyers in choosing between the two models.

The V10 model of the Audi R8 also comes with standard all-wheel drive, while the V8 model is rear-wheel drive. This can make a difference in handling and traction, especially in wet or slippery conditions. Additionally, the V10 model has a 7-speed dual-clutch automatic transmission, while the V8 model has a 6-speed manual transmission.
