To begin building a car to IMSA’s new DPi regulations for the Weather Tech
SportsCar Championship’s Prototype
Class, Cadillac had to select from one
of four approved chassis. Given GM’s
familiarity with Dallara through its
Verizon IndyCar Series program, perhaps
it’s no surprise that the Italian company
with an Indianapolis base was selected.
Next came engine choice, for which
Cadillac had two viable options: use the
twin-turbo V6 from the ATS-V.R that races
in Pirelli World Challenge, or work with the
architecture of the 6.2-liter V8 found in
the CTS-V and Escalade models.
“We looked at all our options and in
the recent history of IMSA, the V8 has
performed quite well in the Prototype
Class,” says Mark Kent. “So this is an
opportunity to showcase a different
engine from the Cadillac range, which all
our analysis indicates will be successful.”
In DPi form, without the benefit of the
CTS-V’s supercharger and with IMSA-
mandated air restrictors making it suck
harder for breath, the engine is set to
produce approximately 600hp at a
maximum allowable 7,600rpm.
For the coupe’s bodywork, Cadillac
tabbed Dillon Blanski from Cadillac’s
Design Group to sculpt the new DPi-V.R.
