What is the difference between the Audi A7 and the Audi S7?

I am debating between the Audi A7 and the Audi S7, but I am not sure what sets them apart from each other. Can someone explain their differences in terms of performance and features?

The main difference between the Audi A7 and the Audi S7 is in their engines. The Audi A7 has a standard 2.0L turbocharged 4-cylinder engine, while the Audi S7 has a more powerful 2.9L twin-turbo V6 engine. This results in the S7 having a higher horsepower and torque, making it a better choice for those looking for a more high-performance vehicle.

Another difference is in the standard features included in each model. The Audi S7 comes with a sport-tuned suspension, Audi's Virtual Cockpit, and a head-up display, while these features are optional in the Audi A7. So if you're looking for a more luxurious and performance-focused car, the S7 would be the way to go.

One important thing to note is that the Audi A7 does offer a plug-in hybrid option, while the Audi S7 does not. So if eco-friendliness is a key factor for you, the A7 might be the better choice.
