Page 1 of 1 Seasoned Italian motorsports manufacturer Dallara was selected as one of just four chassis suppliers for the revised 2017 LMP2 regulations. In addition to building cars under their own name for the FIA and ACO sanctioned series, this also opened the door for the Italian manufacturer to provide chassis for the new DPi formula introduced at the same time by IMSA. For the latter, Dallara partnered with General Motors to create a Cadillac DPi machine.
Both Dallara's own P217 and the Cadillac DPi-V.R. shared the same underpinnings. Conventional in design, these consisted of a carbon-fibre composite chassis, suspended by double wishbones on all four corners. In LMP2 specification, the Dallara featured the spec Gibson V8 engine, mated to an X-Trac six-speed sequential gearbox. The engine used in the DPi car was Cadillac's own 6.2-litre V8. Both cars also feature distinct bodywork with the LMP2 regulations being considerably stricter.
While the Cadillac has been the dominant car in the DPi class since the start of 2017, the Dallara has struggled so far in LMP2 specification against the Oreca 07. Over the 2017/2018 winter, the other three LMP2 manufacturers were allowed some lenience to develop their cars than the rules had originally stipulated. This did help improve the competitiveness and P217s are now more often found at the sharp end of the field. Page 1 of 1
