More questions than answers - see Q&A page
le Mans 24 not in IMSA teams' 2017 plans -
"At no point have we been made aware that our DPi competitors have Le Mans as a priority for 2017," Atherton
IMSA freedom on ECUs will put DPis in LMP1-P for LM24 -
"...a manufacturer using its own engine, electronics and bespoke design bodywork, being able to come to Le Mans is as if not more attractive than what was the original vision," - Atherton
LPM1-P entries would have to feature chassis manufacturer above OEM
" A Dallara-X, an ORECA-Y. A Riley/Multimatic-Z."
"'powered by Mazda' would be acceptable, but if it was 'Mazda' in a five foot tall neon lights, it wouldn't be." - Beaumesnil
ACO insist on spec Costworth ECU for LM24/WEC P2
IMSA allow OEM ECU freedom
"(ECUs) a bigger component of the discussion than any of us originally recognized." - Atherton
Riley say "...I would guess up to five" DPi teams in 2018 - Racer.com
Onroak on DPi: "Things are still unclear and timing remains a problem to solve." - Endurance-info.com
Visit Florida/SDR could still go one of 3 ways -
Onroak generic LMP2

Definitive DPi Atherton interview @ Racer.com
Update from IMSA - via
"(DPi) doesn’t just allow manufacturer involvement, it depends on it." Atherton Sportscar365.com " ...LMP1 Privateer for Le Mans.. an interesting idea"
Q&A from IMSA -
"Teams fielding DPi cars and LM P2 cars will have the ability to use some approved aerodynamic add-ons, enabling them to tune their cars to each track. This will promote diversity in car setup and stimulate competition"
"...it has been understood and acknowledged that IMSA’s business goals and objectives for its top Prototype class differ from the goals of the FIA and ACO"
"prospective DPi manufacturers have revealed a desire to use their own electronics providers rather than using the “spec” Cosworth ECU"
