Dallara’s Evo kit for its P217 LMP2 car involves “very small parts” updates, according to chief designer Luca Pignacca.

The Italian constructor, along with Onroak Automotive and Multimatic-Riley, has been permitted one-time performance evolutions to its LMP2 car for next year, in an effort from the FIA and ACO to bring all three cars up to the Oreca 07’s performance level.

While the Riley Mk. 30 has been allowed chassis and aero updates, both the Dallara and Ligier JS P217 can only make aero updates to both their base cars and Le Mans-specific aero kits.

Pignacca explained the biggest change for the Dallara comes with a new front splitter, and other minor changes.

“On the base car, it’s very small modifications to the front-end of the car,” he told Sportscar365. “Being the base car, it will [also] be common to the Le Mans kit.

“The Le Mans kit will be the same as last year, the one we didn’t race, but with very small new features. Just very small parts.”

All three Dallaras entered in this year’s 24 Hours of Le Mans reverted to the car’s regular-season aero package for the race after sustaining unfavorable results in testing and practice.

“The Le Mans kit was wrong, simple as this,” Pignacca admitted. “We completely missed it. Teams realized it was wrong, very quickly.

“[The Evo kit] will have to be slightly more efficient. But we have to follow the prescriptions of the FIA and ACO. They’ve given us precise targets to reach.”

Aero Changes Applied to Cadillac DPi

Dallara’s Evo kit updates will also be utilized on the Cadillac DPi-V.R, per IMSA rules.

It’s understood any common parts between DPi and LMP2 models must be updated in the case of LMP2 Evos.

“For example, if you do something at the front splitter, this is a common part to the Cadillac,” Pignacca said.

Both LMP2 and DPi variations were tested at Windshear in North Carolina earlier this month, with Dallara waiting on feedback from the FIA and ACO, as of last weekend’s FIA World Endurance Championship season finale in Bahrain.

Newly crowned IMSA WeatherTech SportsCar Champions Wayne Taylor Racing recently conducted straight-line testing with its Cadillac DPi at Kennedy Space Center, understood to validate the updated package.
