Alpine challenges F1 rivals to protest Mercedes engine in Melbourne. Alpine’s Steve Nielsen defends Mercedes’ Power Unit amid compression ratio controversy.

Alpine challenges rivals: “If you think Mercedes is illegal, file a protest”

The debate over compression ratios has quickly become the first major political issue of the new Formula 1 era. Mercedes is reportedly gaining an advantage by exploiting a perfectly legal “grey area” in the regulations, prompting rivals—from Ferrari to Red Bull, Honda, and Audi—to push for an immediate rule change. But Alpine, a Mercedes customer, is warning that altering the rules on the eve of the season could set a dangerous precedent. Alpine’s Managing Director, Steve Nielsen, has issued a direct challenge to dissatisfied teams: if they truly believe the German Power Unit is illegal, they should file a formal protest in Australia.

Alpine’s direct challenge to competitors

Nielsen doesn’t mince words. He believes those alleging irregularities must take responsibility to prove their claims.
“They have the right to protest, I suppose. We’ll go to Melbourne, and if they’re really convinced, then they will have to step up and do something about it.”

He hopes the FIA clarifies the situation before the season begins:
“I don’t know if the FIA will give an opinion before Melbourne. In a sense, I hope they do, because I hope the Melbourne story doesn’t end up revolving around compression ratios.”

The technical point at issue is well known: Mercedes complies with the 16:1 ratio limit in ambient-temperature tests, but the ratio increases when the engine reaches its operating range. Rival teams want to prevent this by pushing for “hot engine” testing.

The risk of a dangerous precedent

For Nielsen, the approach being taken by rival teams is risky:
“The key issue for me is how we’re handling this. If we say that a clearly written regulation can be challenged like this, then what else is off-limits? Everything becomes open to debate.”

He also emphasizes the economic and technical impact of a sudden rule change:
“People invest huge amounts of time and money—especially money—in good faith. And if suddenly everything can be contested… then I think we are in a completely new world we’ve never been in before.”

Nielsen underlines a crucial point:
“Some might say I’m biased because we have a Mercedes engine in our car, but do we really want a sport where clearly written rules can be challenged simply because someone feels like it? That’s for the FIA to answer.”

The battle over compression ratios has just begun

While the dispute is only starting, Alpine’s message is clear: F1 cannot afford to rewrite the rules every time a team finds a more effective interpretation. The FIA will have to decide whether to defend regulatory stability or intervene to appease manufacturers. In the meantime, Nielsen restates Alpine’s confidence:
“We have full trust in Mercedes. They built a Power Unit in good faith, following very clear regulations, and we are satisfied with it.”

The paddock now awaits the Bahrain meeting, but one thing is certain: the first major political fracture of the new technical era has already erupted.
