George Russell’s Car Had “Too Much Input,” Wolff Details Dangerous Software Bug

With rookie sensation Kimi Antonelli currently leading the 2026 Formula 1 Drivers’ Championship and Lewis Hamilton finding his stride over at Ferrari, George Russell’s side of the Mercedes garage is in desperate need of a stable weekend. However, the technical gremlins relentlessly plaguing Russell’s W17 have now evolved from cracked engine blocks into something much more alarming: phantom throttle inputs.

Following yet another compromised session for the British driver, Mercedes Team Principal Toto Wolff was pressed on the exact nature of Russell’s latest mechanical setback. Speaking to Sky Sports F1 , Wolff revealed a highly unsettling drive-by-wire issue that essentially caused the car to accelerate independently of the driver’s foot.

New PU Followed By Phantom Throttle

“We need to find out what it was,” Wolff admitted to the broadcast crew when asked what went wrong with Russell’s car. “There was too much input from the throttle that he didn’t give, and doing [that] is not good. And yeah, we need to get on top of these things.”

In modern Formula 1, the throttle pedal is not mechanically linked to the internal combustion engine. Instead, a highly complex drive-by-wire system interprets the driver’s pedal pressure and relies on software mapping to deliver the requested torque from both the V6 engine and the electrical hybrid systems.

When that software glitches, the results can be terrifying. Getting “too much input” from the throttle without actually pressing the pedal means the powertrain is delivering unexpected torque spikes. On a knife-edge circuit, an uncommanded surge of power mid-corner can easily pitch a car into a spin or send it into the barriers, instantly shattering a driver’s confidence in the machinery underneath them.

This isn’t the first time Mercedes’ 2026 power unit mapping has raised eyebrows in the paddock. Earlier in the season, it was revealed that Brackley engineers were aggressively pushing the absolute limits of the new hybrid regulations by exploiting MGU-K deployment lockouts, which occasionally left their drivers with sudden, bizarre power drops. Now, it appears the calibration bugs have swung in the opposite, far more dangerous direction for Russell’s new power unit.

Currently sitting third in the standings—59 points adrift of his championship-leading teammate—Russell’s path to a maiden title is becoming increasingly steep. Yet, when asked if the 26-year-old was still in the championship fight, Wolff firmly dismissed the notion that Russell is out of the picture.

“Long way to go, absolutely long way to go,” the Mercedes boss declared emphatically.

While the mathematical possibility remains very much alive with the second half of the season looming, Russell’s championship window relies entirely on his engineering team’s ability to lock in a stable baseline. Mercedes has built arguably the fastest car on the 2026 grid, but until they can eradicate these localized software bugs and hardware frailties, Russell will be forced to fight his own car just as hard as his rivals.
