The BoP test took place at Adria and Grugliasco
The test to establish the Balance of Performance for the upcoming season of all the TCR series worldwide took place last week in Italy, first at the Adria International Raceway and then in the Pininfarina wind tunnel at Grugliasco.
Nine brands of car manufacturers were represented; each one had appointed its own test driver to set up the cars before the official TCR testers Nicola Larini and Andrea Belicchi took over to go through the BoP programme.
The list of test drivers included: Mario Ferraris in the Alfa Romeo Giulietta, Swiss lady Rahel Frey in both the Audi RS3 LMS DSG and SEQ cars, Roberto Colciago in the Honda Civic, Mike Halder and Janis Baumanis in the KIA C’eed, Pierre-Yves Corthals in the Opel Astra, Aurélien Comte in the Peugeot 308, Miguel Molina in the SEAT León DSG, Jordi Gené in the SEAT León SEQ, Luigi Ferrara in the Subaru WRX STi and Dieter Depping in both the Volkswagen Golf GTi DSG and SEQ cars.
The FRD Motorsport-built Ford Focus that was also due to join the test did not show up as it still stuck in Amsterdam because of a problem with custom clearance.
In a sunny Adria Larini and Belicchi worked hard while testing the twelve cars.
The first day was dedicated to the performance test that consisted of a five-lap timed stint on the track, with all the cars running on the minimum weight of 1285 kilos, except for the 1.6-litre Peugeot 308 that benefited from a 100-kg reduction.
On the second day the TCR technical department focused on the coast down tests for evaluating the cars’ aerodynamics and fluency; in this case the cars accelerated and were left rolling in neutral, back and forth on the pit straight.
During both days the cars were placed in turns on the rollers of the dynamometer bench to measure dissipation of power, shaft-power, shaft-torque and boost pressure.
At the end of the second day the racing cars where trucked to Grugliasco, where drag and lift coefficients were measured in the Pininfarina wind tunnel on Friday.
The BoP results will be unveiled by the middle of March and they will dictate the BoP for all the TCR series worldwide.
