If you want to see the law of unintended consequences in action, just take a look at MotoGP testing. The nature of testing has changed as manufacturers have suffered the consequences of not fully understanding the effects of the engine development freeze during the season. Honda suffered, Suzuki suffered, and now Yamaha have suffered when they made the wrong choice of engine in preseason testing. They learned the hard way they had to get it right.
This has meant that the Valencia MotoGP test has become first and foremost about getting the engine in the right ballpark, giving the engineers enough data to work out the fine details over the winter. A tight track and cold air temperatures sees engines at their most aggressive, with plenty of horsepower on hand and very little room on track to actually use it. The addition of Jerez as an official winter test – to be held at the end of next week – makes this even more explicitly an engine test. If the factories bring an engine which is manageable at both Valencia and Jerez, they are in good shape for next season.
