Porsche has received the biggest weight break for this weekend’s Imola round of the World Endurance Championship under the Hypercar Balance of Performance.
The German manufacturer’s 963 LMDh will race at the Imola 6 Hours on 20 April 11kg lighter than at the Qatar season-opener in February.
But its weight for the 2025 WEC’s second round of 1053kg is 20kg higher than at the corresponding fixture last year.
Maximum power for the 963 is down 5kW (6.7bhp) on Qatar under the BoP, which is designed to equate performance each manufacturer’s car in Hypercar.
The adjustment follows a disappointing performance at the start of the defence of its WEC drivers’ title crown, the two factory Porsche Penske Motorsport entries ending up 10th and 11th in Qatar.
Last year, the pair of works PPM entries took second and third at the Italian race, which finished in wet conditions.
Alpine’s A424 LMDh and the Peugeot 9X8 2024 have also had weight breaks for Imola of 2kg and 1kg respectively: the Peugeot Le Mans Hypercar is now down on the Hypercar minimum of 1030kg and at the maximum power of 520kW (697bhp).
Cadillac had received the biggest increase in weight in the new BoP table released at the start of this week.
The American manufacturer’s V-Series.R LMDh has been set a minimum weight of 1041kg, up from the 1030kg minimum at Qatar, but has gained 7kW (9.4bhp).
Ferrari has gained 8kg from the 10-hour race in Qatar, in which its three 499P LMHs blocked out the podium positions.
It will also race 4kg heavier than in 2024 when it was on course for victory at its home race before a tactical mistake on the arrival of the rain, but has gained 7kW from Qatar.
Toyota’s GR010 HYBRID LMH remains on a minimum weight of 1065kg but has lost 3kW (4bhp) in power since the 2025 WEC curtain-raiser.
BMW has been given a weight increase of 5kg, while getting an increase of 8kW (10.7bhp) in maximum power.
That explains why the German manufacturer’s M Hybrid V8 LMDh has received the biggest swing under the ‘power gain’ element of the BoP, which adjusts max power above 250km/h (155mph). It has gone from gaining 0.6% in power to losing 1.6%.
The minimum weight for Aston Martin’s new non-hybrid Valkyrie LMH rises 9kg for Imola.
Practice for the Imola 6 Hours begins on Friday 18 April.
