On the eve of the fifth event of the season in Valencia, WTCC promoter Marcello Lotti answered a few questions.
The previous event in Pau was troubled by never-ending technical checks on the engine speed and supercharged air pressure limits. This had never been done before, why did the Stewards decide to ask for these checks in Pau?
“The situation after Marrakech left the FIA no other choice but to adopt the most rigorous approach in enforcing the existing regulations. However, after the event in Pau it became clear that it was not in the interest of the competitors to put the rule maker and referee of WTCC, the FIA, in such a position. Instead, all agreed to ask the FIA to clarify the rules.”
Before Valencia the FIA Technical Department and the FIA Touring Car Bureau issued documents clarifying the engine speed limit and increasing the limit of the supercharged air pressure for the diesel engines to 2.7 bar relative. Another change of regulations then?
“Not at all. As it was clearly indicated these were clarifications of the existing regulations. Before the beginning of the season the FIA fixed the limit of the supercharged air pressure to 2.5 bar relative, a value that was to be adjusted taking into account the outside air pressure and temperature. This resulted in 2.5 bar in Puebla and 2.9 in Marrakech. Now, using the experience from the first four events of the season, the FIA was able to fix a new limit which is due to stay – without fluctuations – until the end of the season. We are confident that this, together with the compensation weight system, will actually balance performance on the track and ensure the close racing we all want to see.”
