GTE Regulations Update: Auto BoP For The ‘Ring & No Mexico-Specific Cooling Changes

Aston Martin get a boost in Pro, but are pulled back in Am

The first fruits of the new for 2017 automated Balance of Performance system have produced the values that will be applied for the 6 Hours of the Nurburgring next weekend in the LM GTE Pro category.

The algorithmically sourced calculations are based on the first two races of the 2017 season and don’t take into account performances at the 24 Hours of Le Mans which is subject to a specific BoP and specific bodywork.

Aston Martin finished 6th and 7th in class at Silverstone and 7th and 8th at Spa, and now receives a 20kg weight break taking the Vantage V8s to 1188 kg, and a power increase thanks to a 0.1 mm larger air restrictor.

The minimum weight of the two Ford GTs has gone up by 20kg, from 1253kg to 1273kg, while the Ferrari 488 GTEs and the Porsche 911 RSRs will race with the same BoP as at Spa and Silverstone.  Turbo boost levels for both Ford and Ferrari are unchanged from the second round of the championship in Belgium.

The LMGTE Am class, which does not utilise the automatic BoP system, sees only one change with the 2016 specification Aston Martin Vantage getting a 0.2 mm smaller air restrictor.

The new system has been introduced this year by the FIA and ACO – with the full support of all the GT manufacturers – using evaluation criteria defined and agreed by all parties before the start of the season.

No additional cooling for Mexico

For the inaugural visit of the FIA WEC to Mexico City last season, supplementary technical regulations were issued aimed at improving the cooling of the engines, brakes, transmissions and electrical /electronic devices in GTE Pro.

A recent update to the technical regulations makes it clear that these are no longer in force and the cars will race in their standard specification in Mexico this season.
