In a new video ad, the Porsche 911 is pitted against itself, but it’s not the only “great” one here. Legendary boxer Muhammad Ali, tennis champion Maria Sharapova and chess grandmaster, Magnus Carlsen also appear in the ad – challenging themselves.

“Greatness comes from within, from pitting you against you,” the narrator says. As the champions go up against themselves, so does the Porsche. While it’s obviously a CGI version of Ali’s younger self, it’s good to see the champ featured in a Porsche ad, don’t you think?

After numerous repeats of “you against you,” the narrator concludes by saying “pitting you against you, until the greatest version of you triumphs.” The ad suggests that the facelifted Porsche 911 has been pitted against its itself, over and over again. It is an iconic model for the brand after all.

The facelifted 991-generation Porsche 911 Carrera and Carrera S were revealed earlier this year at the 2015 Frankfurt Motor Show. In the the rear of both cars, sits a biturbo 3.0 litre flat-six engine. The entry-level Carrera produces a total of 370 PS and 450 Nm, while the Carrera S with a different exhaust system and a tuned engine management system makes 420 PS and 500 Nm.

More recently, Porsche pulled the covers to reveal the facelifted Porsche 911 Turbo and Turbo S. The new styling resembles that of the Carrera variants, however the Turbo and Turbo S gets a 3.8 litre biturbo flat six. The Turbo produces 540 hp, while the Turbo S makes 580 hp – that’s 20 hp more than the outgoing models.

The Turbo goes from 0-100 km/h in 3.0 seconds and the Turbo S in 2.9 seconds. In addition to that, the engines also have a dynamic boost function that enhances throttle response during driving. Furthermore, all receive a Sport Response button which gives the vehicle optimal acceleration for up to 20 seconds. Across the range, the 911s are equipped with a seven-speed PDK dual-clutch automatic transmission.
