The Silver Arrows have subjugated the sport since the introduction of the V6 hybrid era in 2014, winning 51 of the 59 races that have followed. Speaking to The Guardian, Horner insists that change is needed.
"It’s unpalatable to think of it for another three years," Horner insisted. "The new owners of F1 know very much about putting on a great show and there being good and healthy competition. That can’t be artificially done obviously but I would be surprised if they were prepared to allow total dominance like the last three years."
The new regulations that will be in play this season were partly drafted in to help the other teams catch up or even surpass Mercedes. However, it seems that Mercedes are top of the pecking order once again.
"Mercedes dominating again would be bad for the sport," Horner continued. "But how you prevent it from happening I don’t know. It would be wrong to artificially slow someone down. We have just got to work hard to put them under pressure."
