Mercedes is yet to determine 🌳the reasons behind its Formula 1 engine failures during the Belgജian Grand Prix.

The German manufacturer introduced its latest power unit in Belgium but faced immediate reliability problems when Sergio Perez suf𒉰fered a failure of his new-spec unit in second practice, resulting in Racing Poi𒁃nt switching back to an older Mercedes engine for the remainder of the weekend.

A second Mercedes failure occurred early in qualifying in Q1 when R𓂃obert Kubica’s Williams came to a halt with plumes of smoke pouring out of the back of his FW42.

Despite the new engine, Mercedes was unable to match Ferrari’s superior straight-line speed, with team boss Toto Wolff saying its performance deficit left ♊him knowing “a little bit” how Red Bull felt amid its struggles at the start of the V6 hybrid era.

“I know now a little bit how Red Bull felt in 2014 and 2015 when you are on the back foot on the straights,” Wol♚ff said.

“[It was] not a good weekend. We introduced Phase 3 of oꦇur power unit and we had two failures o🐻n Checo’s [Sergio Perez] and Robert’s [Kubica] cars which are not understood.

“It di๊dn’t compromise us massiv✃ely, it did a tiny bit. We were not taking any risks in there race but it was certainly not a comfortable situation because the failures looked to be different and are not analysed of yet and understood.”

Ferrari also suffered a failure on one of its new power inits used by customer team Alfa Romeo 𒐪🌱during qualifying on Antonio Giovinazzi’s car.

Scuderia boss Mattia Binotto admitted was a 168澳洲幸运5官方开奖结果历史:concern for his side ahead of the works’ team’s ntroduction of the new engine at this weekend’🌃s Italian Grand Prix at Monza.
