Tuned Audi S8 Plus Hits the Autobahn for Some Testing

Tuned Audi S8 Plus Autobahn

The already potent Audi S8 Plus gets even more so with a simple upgrade and the flip of a switch.

A few years ago, the Audi S8 Plus debuted for those that didn’t think that the regular S8‘s 520 horsepower output was quite enough, upping that ante to a cool 605 raging ponies. The Plus model also received some chassis enhancements with a stiffer suspension and bigger brakes to make the best of that extra power, along with unique interior and exterior treatments, but let’s be honest – the main draw here is the car’s twin-turbocharged 4.0-liter V8, which in stock form, can propel the sedan from 0-60 in just 3.3 seconds. However, as we can see in this video from AutoTopNL, a tune can also unleash even more power from this already potent offering.

Recently, the crew behind this particular YouTube channel – which routinely tests different vehicles’ top speeds on Germany’s Autobahn – installed a RaceChip in their Audi S8 Plus, and were quite pleased with the results of that upgrade. Soon, a viewer reached out to see if they could install the same part in his own car and do some testing, and who wouldn’t agree to something like that, honestly?

For this particular scientific experiment, AutoTopNL started out with the car in stock form to get a baseline, while also discussing the gains that the RaceChip adds to the mix – around 95 horsepower and 100 pound-feet of torque. In terms of acceleration, the stock Audi S8 Plus accelerated from 100 kilometers per hour to 200 – or 62-124 miles-per-hour – in eight seconds flat, while the tune slashes that number to just 7.27 seconds.

That number places the tuned Audi S8 Plus just behind the Porsche Cayenne Turbo with PP Performance upgrades and in front of vehicles like the Lamborghini Urus from Mansory, the Nissan GT-R Nismo, BMW M3 Competition, and Audi e-tron GT, to name just a few – impressive company, indeed. On a corresponding top speed run, the team manages to get the car up to 198 mph – higher than the stock car’s governed limit of around 190 mph, too.

The beauty of this particular combination is that the tuned S8 Plus isn’t just absurdly quick, but it’s also quite comfortable to cruise around in, plus, the tune can be turned on and off with the push of a button, in the event that one wants to do so. Truthfully, it’s hard to imagine a better daily driver, one that’s equal parts civilized and capable of outrunning even some exotic machinery when called upon.
