Andretti Confident Ferrari Will Catch Up Amid 2026 Engine Loophole Debate

As the FIA prepares to address potential loopholes in the 2026 power unit regulations, Cadillac representative Mario Andretti suggests the situation is akin to lawyers interpreting the law. While some manufacturers may have found a "grey area" to gain an early advantage, Andretti is unfazed, expressing full confidence that Ferrari will catch up if they are initially behind.

Why it matters:

With the 2026 regulations introducing a massive overhaul involving 50% electrification and sustainable fuels, the power unit race is tighter than ever. A technical loophole allowing for higher compression ratios could give certain teams a significant head start in performance and efficiency, potentially skewing the competitive balance before the season even begins.

The details:

• The Grey Area: Andretti compared engineering to legal practice, noting that some are simply better at reading the rules to find the limit before crossing into the red. He acknowledged that engines are already designed, making a clarification meeting "almost too late."
• The Regulation: The controversy centers on Article C.5.4.3. of the Technical Regulations, which caps the geometric compression ratio at 16.0. The issue lies in how this value is measured and approved by the FIA.
• Technical Theory: Reports suggest some manufacturers may have exploited the wording by using connecting rods that expand when the engine reaches operating temperature. This could theoretically allow the compression ratio to increase beyond the limit during actual use, boosting power and fuel efficiency.
• FIA Action: Technical experts are scheduled to meet on January 22 to clarify these interpretations and ensure all participants are on a level playing field.

What's next:

Andretti emphasized that Ferrari is the ideal partner for Cadillac's debut, trusting their ability to adapt. Even if the Scuderia missed an initial trick, their resources and history suggest they will rectify any deficit quickly, ensuring Cadillac remains competitive when they join the grid.
