Because Elon Musk loves to say things on Twitter.
The only person anywhere near as capable as creating headlines from a Twitter post as America's current Commander In Chief is Tesla's CEO, Elon Musk. The whole drama of the Tesla S going to the Nurburgring to claim Porsche's non-production electric 4-door car "record" started with a tweet from Musk that simply said: "Model S on Nürburgring next week." Now we've got claims it's running 20 seconds a lap faster than the Porsche Taycan, with Porsche countering it wasn't actually the faster Taycan S that set the original lap time. That drama will continue, but in the meantime, Musk is claiming the Roadster will take the very real overall production car record at the Nurburgring.
The confirmation of Musk's belief in the upcoming Tesla Roadster comes from a reply to a Tesla fan asking: "I guess new Roadster will easily beat the all-time record of 6:44.97s?" To which Musk ironically replied: "Absolutely."
For those that follow the Nurburgring lap time bragging rights competition and need a refresher, the current fastest production car at the iconic German track is Lamborghini's Aventador supercar in its even more brutally fast SVJ form. The reason Musk's assured response raises eyebrows is because there are some crazy cars that make the Aventador SVJ look cute coming down the pipeline, including Lotus's 1,973-horsepower all-electric Evija and the long-awaited Mercedes-AMG One.
The most likely car to take the overall production record, and possibly the overall fastest time of any car, is the 1,160-horsepower Aston Martin's Valkyrie. That record is currently at 5 minutes and 19.545 seconds and owned by Porsche's insane 919 Hybrid Evo race car.
Tesla's new Roadster was first seen as a prototype around two years ago and, as far as we know, it'll have three motors translating the power from a monstrous 200 kWh battery pack. Tesla claims it will sprint to 60 mph in 1.9 seconds and 100 mph in 4.2 seconds. At this point, it's hard to tell whether the top-spec will actually include a 'Space X package' with thrusters hidden behind the license plate or not.
