If you’ve been following the buzz around Formula 1’s big 2026 F1 regulations shake-up, one number has everyone talking: 400km/h. That’s right, speeds that could make your heart race faster than a qualifying lap. Mercedes boss Toto Wolff dropped this bombshell back in August, insisting the new cars could theoretically hit that mark, or even push beyond it. But is it hype, reality, or just a clever sales pitch for the upcoming power units? Let’s break it down.
The 2026 F1 Regulations
The 2026 F1 rules promise a massive overhaul. Power units shift to a near 50-50 split between combustion and electric power, ditching the current hybrid setup for something fresh. Cars get less downforce and drag, paired with active aerodynamics to keep straight-line speeds blistering.
Toto Wolff addressed the scepticism on the Beyond The Grid podcast, explaining his bold claim was partly to hype the tech. “Well, I felt like we need to give that engine a little bit of a marketing boost, because people were talking it down and it’s such an amazing piece of kit,” he said.
Toto Wolff Teases A Potential 400km/h Speed
Put it all together, and boom, 400km/h becomes possible, at least in theory. But there’s a catch: you’d burn through your energy stash before the next straight, leaving you crawling compared to rivals. “If you put it all together, we could do 400km/h or maybe even exceed it, but obviously you’re going to run out of energy for the next straight and then not be quick enough,” Toto Wolff added
Mercedes’ High Performance Powertrains director Hywel Thomas jumped in with the nitty-gritty. These cars will explode off the line early in straights, even better than today’s beasts. No electric motor on the turbo means potential lag, but electric boost fills that gap for an “epic” start. The downside?
Energy runs dry quicker, forcing teams to ease off midway. “I think the start-of-straight performance is going to be very, very similar to today. We’ve got the turbocharger that hasn’t got an electric machine on it anymore, so you could get some turbo lag. We’ll be filling in that turbo lag with the electric, potentially.” Thomas noted.
“So, I think in terms of start-straight, the performance is going to be pretty epic in comparison to what we’ve got today. But we know we’re going to start to derate earlier on the straight because we haven’t got enough electrical energy to use it all the time,” he added
This tease has the paddock buzzing ahead of testing. Red Bull, Ferrari, McLaren, all eyes on those power units. If Wolff’s right, 2026 delivers pure cinema. Stay locked in; the revolution revs up soon.
