Action Express Racing and Wayne Taylor Racing each will field Cadillac DPi-V.R machines next season. Action Express, which has won the last three WeatherTech Championship Prototype titles, will have a pair of Cadillacs, while the Wayne Taylor Racing team continues its longstanding relationship with General Motors through a one-car effort.
The Cadillac DPi-V.R will be powered by a naturally aspirated, 6.2-liter Cadillac V8 engine, which shares inherent architecture with engines that power the third-generation Cadillac CTS-V and fifth-generation Cadillac Escalade production vehicles. The chassis for the Cadillac DPi-V.R was designed in cooperation with Dallara, with styling cues inspired by Cadillac’s current line of V-Performance high-performance production models, specifically the Cadillac CTS-V.
The DPi-V.R will make its public on-track debut during a two-day IMSA-sanctioned test at Daytona International Speedway on Dec. 13-14.
Cadillac joins Mazda and Nissan as confirmed DPi manufacturers for IMSA’s top Prototype class, which also will include international LMP2 prototype chassis from Riley/Multimatic, Ligier, ORECA and Dallara, powered by single-specification Gibson V8 engines.
