Among the many innovations brought to the sport during the last season was an element of ‘show and tell’. Formula 1 engineers are, by nature, extremely secretive. Many would say overly secretive.
However, there are many fans who take a keen interest in the technical aspects of the cars and follow their development avidly. The show and tell requires each team to disclose to the FIA the changes it’s made to its cars. The FIA then collates and publishes this while the team has to put its cars, and a reluctant engineer, on display to journalists before the cars run on Friday.
Really I’d say the bearings sustained more pressure but hey that’s just me maybe both.
The irony is that pistons are such an outdated concept in the cutting edge F1 series. Three cheers for creating lots of mini explosions!
