What sets the Audi R8's V10 engine apart from other supercars?

I've heard a lot about the Audi R8's impressive engine, but what makes it truly unique and stand out among other high-performance cars?

The Audi R8's V10 engine has a unique feature called 'Cylinder on Demand' which deactivates five of the ten cylinders during low-load situations, resulting in improved fuel efficiency without sacrificing performance. It's a clever engineering solution that sets the R8 apart from its competitors.

One of the things that makes the Audi R8's V10 engine special is its high-revving nature. It can rev up to 8,700 rpm, which not only creates an incredible sound but also delivers instant power response. This is thanks to its lightweight and compact design, making it an impressive feat of engineering.
