Christian Horner responds to Red Bull and Mercedes power unit loophole rumours

• Mercedes and Red Bull are thought to have made use of the fact that it will only be measured when the car is static at ambient temperature, allowing the compression ratio to rise to 18:1 when the engine is in motion and up to operating temperatures, although it is worth noting that this has not been confirmed."Formula 1 is about pushing the boundaries.
• It's about how you interpret regulations.
• Always has been, always will be," Horner said as he danced around the question."Teams that are the most conservative are the teams that are never at the front of the grid.
• You've got to be pushing the envelope.
• And of course, it's all about how you interpret regulations, and engineers, some of the brightest engineers on the planet, will be looking at those regulations and thinking, 'OK, how can I maximise performance?'"AdvertisementAdvertisementAdvertisementMercedes team chief Toto Wolff responded to complaints from other power unit manufacturers at the official launch of the W17.
