De Tomaso P900 CSR2 — Best Tune, Shift Pattern & Stage 6 Guide

The CSR2 De Tomaso P900 sits sixth in the Tier 5 standings with a fully maxed best time of 6.581 seconds. It's one of the more technically interesting cars in the top ten — not because of what it has, but because of what it doesn't. No turbochargers. No hybrid system. Just a 7.0-litre naturally aspirated V12 screaming to 10,200 rpm and 900 horsepower. In a tier full of electrified machinery and racing prototypes, the csr2 de tomaso p900 makes its case on pure combustion engineering and a launch pattern that most drivers get wrong the first time: you skip second gear entirely.

About the De Tomaso P900

De Tomaso Automobili built the P900 with Italian engineering firm ItalTecnica, and what makes it unusual in 2026 is what they chose not to do. No turbocharger. No hybrid. No electrification. Just a 7.0-litre naturally aspirated V12 with a 10,200 rpm redline, a gear-driven valve timing cascade borrowed from Formula 1 practice, and an eight-stage dry sump to keep oil in place during sustained track use. The whole engine comes in under 200 kilograms. For context, that's lighter than the battery packs on several of the electric hypercars it's competing against in CSR2.

Only 18 P900s will be built at around $3 million each. Rear-wheel drive, track-only, synthetic carbon-neutral fuel. De Tomaso runs a dedicated racing programme called the Vittoria for owners and provides Nürburgring storage — because these cars aren't being driven to the shops. In CSR2 it's a Prestige Cup and Hypercar Crucible prize car, and getting one fully built takes a meaningful key and fusion investment on top of earning it.

Stage 5 Baseline

With all Stage 5 upgrades installed and all fusion slots filled but no Stage 6 parts, the P900 runs 8.084 seconds. That's a solid Stage 5 result and a decent platform to work from while you build up the bronze key stack for Stage 6 parts. Make sure every fusion slot is filled before you start Stage 6 investment — the NOS tune values below assume complete fusions. If yours aren't all in yet, the BHP figure will read lower in-game. Use 4.0 SEC as your reference until fusions are complete.

CSR2 De Tomaso P900 Best Tune

These are the numbers for the fully built car — all Stage 6 parts in, all fusion slots filled. The csr2 p900 tune at this configuration runs 6.581 seconds.

Full GRIP (100) is the correct setting on the P900. The rear-wheel drive V12 layout wants as much mechanical traction off the line as possible — nudging toward ACC doesn't help the launch on this car. On NOS: 188 BHP is right when fusions are complete. If they're not all in yet the in-game BHP will read lower — ignore it and tune to 4.0 SEC instead. The shift pattern doesn't change between the two states.

De Tomaso P900 Shift Pattern

The start is a Perfect Start — release the brake in the middle of the 2 as the countdown ticks down. That's where the P900 diverges from most T5 cars.

You skip second gear entirely. The moment the race starts, you go straight to third and hit NOS there — not in second, in third. From that point every remaining gear is a late shift: hold close to maximum RPM before moving up. Late into fourth, late into fifth, late into sixth. The P900 rewards that patience on the late shifts — rushing them gives up the time that the clean third-gear NOS launch earned. Once you've run the skip-to-third a few times it becomes one of the more consistent patterns in the T5 field, unusual enough that it sticks in memory.

Fusions

You need all fusion slots filled to get the tune working and to hit 6.581. If you're not there yet, your in-game NOS reading will be somewhere between the BHP and SEC values — just use 4.0 SEC until you're done. The P900 is an Italian manufacturer car, so De Tomaso-specific bronze key crates target the right parts better than general ones when they're available through Prestige Cup event windows.

Getting the P900 in CSR2

The De Tomaso P900 Concept is a prize car available through the Prestige Cup cycle and was featured in the Hypercar Crucible event. If you missed the window, it cycles back through Prestige Cup — timing varies. Building to 6.581 seconds means Stage 6 investment on top of the acquisition, and the key and fusion grind are part of that build cost. If you want to skip the grind and get the P900 built correctly from the start, that's what CSR2 mods are for.
