As technologically advanced as the all-new Audi A8 is, an ultra-quick S-version has yet to come out, which makes the older S8 Plus model the one to have if all you crave is performance.
Russian tuner TopCar apparently has something planned for the old S8, and it's called the RS 900 kit. While they've yet to confirm any sort of specs, we'll just go ahead and assume/hope the '900' stands for horsepower.
A front spoiler lip, custom wheels and a new rear diffuser with rectangular tailpipe housings (instead of just round tips), are also visible, adding to the luxury saloon's already aggressive exterior.
Even without any extra mods, the S8 Plus is one heck of a speedster, putting down 605 PS and 700 Nm (516 lb-ft) of torque through all four wheels. In a straight line, it will do 0-100 km/h (62 mph) in just 3.8 seconds.
Adding another 300 or so horses should make it a lot quicker, both off the line as well as mid-range. Let's hope the tuner shines some more light on their latest project sooner rather than later, as we'd love to see this thing in action.
