Fabio Quartararo’s difficult Aragon Grand Prix weekend took another turn for the worse when his Yamaha engine failed spectacularly during Saturday’s Sprint, adding to a growing list of reliability and performance concerns for the Japanese manufacturer.
The 2021 MotoGP world champion had already sensed something was wrong from the opening lap. After nearly stalling at the start, Quartararo noticed his bike losing power on the straights and quickly feared the engine was heading for failure.
“I knew it was going to blow up,” Quartararo said after the incident.
The Frenchman was running 16th when smoke began pouring from his Yamaha, forcing him to retire from the Sprint. The failure was particularly frustrating as it followed a similar warning sign during the Thailand Grand Prix earlier in the season.
While Yamaha experienced several engine failures with its new V4 project during pre-season testing, Quartararo’s Aragon retirement marked the manufacturer’s first major race-weekend engine failure of the season.

Yamaha’s status as a Rank D manufacturer gives each rider an allowance of up to 10 engines for the season, two more than most of its rivals. However, Quartararo’s concern over whether the failed unit was a high-mileage engine highlights the importance of managing the remaining power units as the season progresses.
The engine problem was only the latest setback in a frustrating weekend for Quartararo. He qualified 17th at Aragon, a circuit where he has traditionally struggled, before also dealing with a malfunctioning rear ride-height device during the early stages of the Sprint.
That issue cost him further time, leaving Quartararo unable to make significant progress through the field before the engine failure brought his race to an early end. Teammate Jack Miller provided a brighter result for Yamaha by finishing 10th.
Yamaha had arrived in Aragon with several new components, including a revised chassis, as it continues its search for greater performance. However, Quartararo admitted the weekend felt more like a test than a normal Grand Prix.
The team has been switching between bikes and evaluating different parts throughout the weekend, with Quartararo once again heavily involved in the development process.
For the Frenchman, the focus now is on finding answers rather than simply chasing results. But with another engine failure adding to Yamaha’s concerns, the manufacturer faces an increasingly important reliability challenge alongside its ongoing performance struggles.
