Why is the Audi R8's V10 engine referred to as "non-turbocharged"?

I've noticed that many performance cars, including the Audi R8, often boast about having a non-turbocharged engine. But what does that even mean? And does it offer any advantages over turbocharged engines?

The term "non-turbocharged" simply means that the engine does not have a turbocharger that increases the engine's power output. In the case of the Audi R8, this means that the V10 engine does not have an additional air compressor to boost the air intake and create more power. While this may seem like a disadvantage, non-turbocharged engines often have better throttle response and a smoother power delivery compared to their turbocharged counterparts.

The Audi R8's V10 engine utilizes a naturally aspirated design, which means it relies solely on the engine's displacement to generate power. This results in a higher revving and more responsive engine, which enhances the overall driving experience. Plus, the maintenance costs for a non-turbocharged engine are typically lower due to the absence of a turbocharger, which is a complex and expensive component to replace when it fails.
