Sebring 12 Hours: IMSA BoP an embarrassing waste of time - di Resta

United Autosports driver Paul di Resta has described the IMSA SportsCar Championship's Prototype class Balance of Performance system as an "embarrassing waste of time"

Sebring 12 Hours: IMSA BoP an embarrassing waste of time - di Resta

Di Resta and team-mates Phil Hanson and Alex Brundle - standing in for an unwell Bruno Senna - finished fifth in Saturday's Sebring 12 Hours, and second among the LMP2 contingent in their Ligier JSP217.

IMSA operates a BoP system to allow LMP2s to race against Daytona Prototype international cars - which are based on LMP2 models - in the same class, based around the theoretical performance of the fastest LMP2 car.

But in both the Daytona 24 Hours season opener and at Sebring, the DPi cars have held a decisive advantage in qualifying and race trim.

DPi entries swept the top 10 in qualifying for Sebring, and locked out the podium in the race with the #22 ESM Nissan Onroak winning from two Cadillac DPi-V.Rs, the #10 car Wayne Taylor Racing and the #31 of Action Express Racing.

Ex-Formula 1 driver di Resta, making only his second sportscar racing start at Sebring, said IMSA must urgently address the disparity between the DPis and LMP2s.

"Overall a satisfying result - fifth, and on the lead lap, is a decent result taking into account that currently it is totally impossible to race against the DPi cars," he said.

"The Balance of Performance is an embarrassing waste of time - IMSA must get it sorted if they want teams from Europe to head here."

United owner and McLaren F1 CEO Zak Brown echoed di Resta's comments, saying LMP2 cars "cannot currently compete" against their DPi rivals.

"I'm extremely proud of our team's performance but it's abundantly clear that the LMP2 class cars are in another category [compared to DPi]," said Brown.

"LMP2 cars cannot currently compete on development and subsequent pace.

"We are racing with the hope the DPi cars are unreliable. We didn't have the speed to race them here."

United is only entering the four North American Endurance Cup rounds on the 2018 IMSA schedule, and will make its next appearance at Watkins Glen at the start of the July.

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
