IMSA SportsCar Championship LMP2 class hit with first BoP change

The performance of the latest-generation LMP2 cars has been pegged back for the first time in the IMSA SportsCar Championship ahead of next month's Laguna Seca round

IMSA SportsCar Championship LMP2 class hit with first BoP change

The Balance of Performance changes follow a run of three consecutive victories for P2 cars over the Daytona Prototype international machinery that had previously won all bar one IMSA round since the current rules were introduced at the start of 2017.

All LMP2s have been given an additional 10kg, bringing their minimum weight to 940kg, and also had their fuel capacity reduced from 75 to 72 litres for the Laguna event on September 9.

At the same time, all DPis have had their fuel capacity increased by two litres and the Mazda RT24-P given a 10kg weight break.

IMSA rules boss Geoff Carter said: "We've seen the LMP2 platform develop in terms of performance.

"Even though it's a spec platform, we've seen the car and the performance increase as the competitors have become more familiar with them."

IMSA had previously attempted to balance the DPis, which are built around LMP2 chassis, to the P2s powered by the one-make Gibson V8 engine.

Carter explained that it was "time to put a limit on the reference platform, instead of just turning up the DPis".

He revealed that IMSA's agreement with WEC promoter and Le Mans 24 Hours organiser the Automobile Club de l'Ouest to use the LMP2 regulations allowed for BoP changes to the P2s.

"We've had freedom: the only stipulation is that we don't BoP between (LMP2) cars," he said.

The changes to the P2 BoP only affects the ORECA-Gibson 07 because the PR1/Mathiasen squad is swapping from the Ligier JSP217 to the ORECA for Laguna.

The JDC/Miller team won the Watkins Glen 6 Hours in July, before CORE Autosport triumphed Mosport and then Road America in July and August respectively.

IMSA will split the DPi and LMP2 cars into separate classes in 2019, with the manufacturer-backed DPi class operating as the top-tier.

The performance of the DPis will be less restricted than at present and P2 will become a pro-am division.

Several teams have since announced moves into IMSA's DPi class, with IndyCar squad Juncos Racing and JDC-Miller Motorsports stepping up for 2019.

Why two names for the same thing could cloud sportscar racing's new golden era

OPINION: The adoption by IMSA of the GTP name for its forthcoming LMDh versus Le Mans Hypercar era in 2023 appeals to fans of nostalgia - but it undermines the commonality achieved by bringing its rulebook into line with the World Endurance Championship. GTP or Hypercar, both sides should settle on a single name
