One reason: it's gorgeous.
It can be very easy to get confused regarding which car is which in Audi's current lineup. Compare, as perhaps the best examples, the Audi A6 to the A8. Looking at them side by side and, well, the latter simply looks like a stretched version of the former. It's literally like a Russian Matryoshka doll set. But the Audi A7 is different. First launched in 2010 and updated for 2016, the A7 (and more powerful S7 and RS 7) is based on the same platform as the A6, only it's been given a liftback design, a la the Tesla Model S.
And, voila!, you've got your "four-door coupe," a luxury sedan craze that began with the Mercedes-Benz CLS-Class. This liftback design, fortunately, takes the rather Plain Jane A6 and adds a much-needed dose of sex appeal. The A7, simply put, is gorgeous.
Our tester for our latest review came powered by Audi's supercharged 3.0-liter V6 with 333 hp and 325 lb-ft of torque. Power is sent to all four wheels via an eight-speed automatic. Don't let that "four-door coupe" description fool you; the A7 is a big car and it drives like one. But it's pretty darn fast considering its size, going from 0-60 mph in 4.7 seconds. So, if you're in the market, should you opt for the A7 over the A6? Uh, yeah. Special thanks to Niello Audi-Sacramento for letting us film the car.
