Lamborghini appears to have taken the biggest hit of the LMGT3 manufacturers in the Balance of Performance released for next week’s 24 Hours of Le Mans.
The Italian manufacturer’s Huracan GT3 EVO2 is the only car to have both lost power compared to the previous round of the FIA World Endurance Championship at Spa, while it has also had the largest weight increase of the nine models in the class.
It now weighs in at 1355 kg, the joint-heaviest in the field along with the Lexus RC F GT3, an increase of 25 kg from Spa.
At the same time, its power figure is now given as ‘P15’, indicating 15 percent below the theoretical maximum, compared with 14 percent previously.
On the other hand, the Huracan’s Power Gain, the amount by which a car’s power is increased or decreased above a threshold of 200 km/h (124.3 mph), has been changed to minus one percent, up from minus three.
The rule makers consider the BoP for Le Mans to be separate from the rest of the WEC season due to the nature of the Circuit de la Sarthe, hence why the official bulletin does not display plus or minus figures for power and weight.
All nine LMGT3 cars will run heavier at Le Mans than they did in Belgium, although the increases range from a single kilogram for the Porsche 911 GT3 R to the 25 kg by which the Lamborghini has been upped.
Aston Martin’s Vantage GT3 Evo has been handed the next-largest increase of 22 kg, putting the car at 1349 kg, although the British manufacturer has had its power upped by two percent compared to Spa.
The power increase however is accompanied by the elimination of the Aston’s previous four percent Power Gain.
The only other cars with increases of more than 10 kg from the previous WEC race are the Chevrolet Corvette Z06 GT3.R (+11 kg/1347 kg) and the Lexus (+10 kg/1355 kg).
Besides the Porsche, which now runs at 1327 kg, the smallest increases have gone to the Ferrari 296 GT3 (+2 kg/1345 kg) and the BMW M4 GT3 (+3 kg/1331 kg).
The Ford Mustang GT3 has seen its weight go up by 9 kg to 1327 kg, but this has been accompanied by a two percent power increase.
With one percent power increases are the Corvette, Ferrari, Lexus and Porsche, while the BMW and McLaren 720S GT3, which has had its minimum weight upped by 6 kg (now 1339 kg), are the only cars to have no changes to their base power levels.
The only car with a positive Power Gain for Le Mans is the BMW, which gains one percent above 200 km/h, with all bar two cars having a less favorable figure than before.
The exceptions are the Lamborghini and the Lexus, the latter remaining at zero to put it level with the McLaren and Porsche as well as the Aston Martin.
Corvette and Ferrari see the largest drops of minus two percent, with the Ford joining Lamborghini on minus one percent.
The system of success ballast that is used in LMGT3 for regular WEC races is not in place for Le Mans.
