What are the most important technical specs to consider when purchasing an Audi A7?

I'm in the market for a new car and have my eye on the Audi A7, but I want to make sure I'm making an informed decision. What technical specifications should I pay attention to when comparing different models?

First and foremost, you'll want to consider the engine options available in the Audi A7. The standard 2.0-liter turbocharged four-cylinder engine offers decent power and efficiency, but if you want a more exhilarating driving experience, go for the 3.0-liter V6 or the more powerful RS 7 with a twin-turbo V8 engine.

In addition to the engine, pay attention to the transmission options. The A7 comes with a seven-speed dual-clutch automatic transmission, but some models also offer an eight-speed automatic transmission for a smoother and more responsive driving experience.
