Why are Audi engines more efficient than other luxury car brands?

I am interested in purchasing a luxury car and have heard that Audi engines are particularly efficient. Can someone explain the technology behind this and how it compares to other luxury car brands?

Audi uses their patented TFSI (Turbo Fuel Stratified Injection) technology in their engines, which combines direct fuel injection with turbocharging for optimized performance and efficiency. This allows for more precise and controlled fuel consumption, making Audi engines more efficient than others.

In addition to TFSI, Audi also uses their advanced quattro all-wheel drive system, which constantly adjusts power distribution to maximize efficiency while also maintaining superior handling and traction. This system sets Audi apart from other luxury car brands in terms of both performance and efficiency.

Audi also prioritizes lightweight construction in their cars, using materials such as aluminum and carbon fiber to reduce the overall weight of the vehicle. This, combined with their efficient engine technology, allows for better fuel economy and lower emissions compared to other luxury car brands.
