The Cadillac DPi-V.R is powered by a race-prepared, 6.2-liter V8 engine
which shares inherent architecture with
the engines of the Cadillac CTS-V and
Escalade production vehicles.
While the CTS-V’s LT4 V8 is
supercharged, the DPi-V.R is naturally
aspirated, pushing out approximately
600hp with the series-mandated air
restrictors in place – that’s around 40hp
less than the CTS-V produces.
Packaging the engine within the tight
confines of the Dallara chassis required a
wholesale rethink from Cadillac and its
technical partner, ECR Engines, especially
for the front accessory drive and the oil
pump systems. The all-new front cover
provides engine mounting provisions, as
well as fluid-handling capabilities.
Also now mounted on the front face of
the engine is the oil tank, which fits into a
small recess in the chassis bulkhead
behind the driver.
The overall result is a more compact
package that offers benefits such as
reduced line length, as well as eliminating
the need to make oil line connections
during an engine installation.
Drive to the rear wheels is via a paddle-shift, 6-speed sequential Xtrac gearbox.
Finally, the exhaust system was
redesigned in order to exit from the top of
the bodywork, versus the side of the car.
