Nissan Onroak DPi (DPi)
The Nissan Onroak DPi is a purpose-built American IMSA Daytona Prototype international entry that pairs Nissan branding with an Onroak-designed chassis and a naturally aspirated V8 powertrain. Built for endurance racing, it was designed to battle at the sharp end of the prototype field with aggressive aerodynamics, big downforce, and long-run stability.

In the Simulator Feel
The Nissan Onroak DPi feels like a classic endurance prototype: fast, planted, and demanding without being wildly unforgiving. It has the kind of aero grip and chassis stability that lets you attack high-speed corners with confidence, but it still needs respect under braking and on throttle transitions. Compared with lighter open-wheel cars, it rewards a smoother, more deliberate rhythm — the sort that pays off over a long stint.
Engine & Sound: The naturally aspirated V8 is the star of the show, delivering a deep, muscular bark on the way up the rev range and a hard-edged mechanical howl near redline. Throttle response is immediate, and the power delivery feels linear and usable, making it easy to meter out traction on corner exit while still giving you that prototype punch down the straights.
Handling Characteristics:
Cornering: Strong front-end bite with stable mid-corner balance. It rotates well when set up properly, but excessive aggression can trigger understeer or snap oversteer depending on speed and aero load.
Traction: Good rear grip for a prototype, though wheelspin can appear if you’re too eager with the throttle out of slower bends.
Braking: Excellent stopping power with solid modulation, but trail braking needs finesse to keep the rear settled.
Top Speed: Competitive on long straights, especially with draft, though actual pace depends heavily on BoP and track layout.
Driving Style Tip: Drive it like an endurance weapon, not a qualifying car. Smooth inputs, clean curb usage, and disciplined braking make the DPi come alive. It shines on flowing, high-speed circuits and in multi-class traffic where its stability and visibility help over long runs.
Livery & Aesthetics: The Nissan Onroak DPi has the unmistakable look of a modern prototype: low, wide, and brutal, with dramatic aero surfaces and a race-ready presence. The Nissan branding gives it a factory-backed identity, while the Onroak chassis lines make it look every bit the serious IMSA contender.
Whether you’re hunting lap time or grinding through an endurance stint, the Nissan Onroak DPi delivers the full prototype experience — muscular V8 sound, high-speed confidence, and real race car character.
