The S8 is the mechanically-upgraded, high-performance version of the Audi A8, fitted standard with Audi's quattro all-wheel drive system, and was only offered with a short-wheelbase for the first three generations, being joined by a long-wheelbase variant option for the fourth generation.

Based on the spacious and comfortable A8 sedan, the S8 offers all the trappings of a large luxury car including available massaging seats, high-tech infotainment, and a quiet cabin lined with upscale materials.

With the launch of the V-10 engine in the Audi S8 and S6 sports sedans, Audi's U.S. lineup now offers seven engines, varying from four to 12 cylinders (even numbers only), and the future is rumored to involve a return of the turbocharged five-cylinder in the Audi TT-RS sports car.

Both Audi and BMW are known for their luxury vehicles, but Audi comes out as the superior brand for earning its trust in providing the best features for the greatest value.

BMW and Audi are both high-end brands, with prices that reflect their quality and performance. However, there are some differences in cost between the two brands. On average, BMWs tend to be slightly more expensive than Audis, with a higher starting price for most models.

The V8 is more of a driver's car because it's lighter (1585kg vs 1720kg) and more fluid, but the V10 just makes you feel more special. For that reason, I'd take the one with the big bark; the noise and the acceleration were like nothing like I've ever felt and I'm already in need of an R8 V10 fix.

155 mph Audi claims a top speed of 155 mph, and there are fuel-saving systems, too, including cylinder deactivation and a mild-hybrid setup with a small electric motor and battery.

Audi is a better automaker for those who want to save some money without compromising on features, safety, or performance. Audi is highly competitive in the luxury small car and luxury sports car classes. Mercedes sets the bar high when it comes to interior luxury.

If you prioritize sporty handling and precise steering, BMW may be the better choice. If you prefer a more comfortable and refined driving experience, Audi may be the better choice. Ultimately, the choice comes down to personal taste and which brand speaks to you more.

Similarly, V10 engines produce more power (HP) than V6 and V8s. From this graph, you can clearly see the difference in HP in V engines. Added cylinder means a larger and heavier engine that will burn more fuel. To get the same power output, a smaller engine can be modified such as turbocharging or supercharging.

But only one main frequency makes its way from the engine. Down the exhaust and to our ears as the dominant sound of a car and that is called the RIT.
