It is the year 2026, and the roads of Mexico are still littered with battered cacti, airborne Bugattis, and completionists quietly sobbing into their controllers. Why? Because even after countless updates, seasonal playlists, and over 800 vehicles now filling the Forza Horizon 5 garage, five elusive machines continue to mock collectors from deep within the Car Mastery system. No amount of Wheelspin luck or Autoshow credits will put them in your driveway. They are the hidden skill tree cars, and unlocking them is a peculiar blend of ritualistic grinding and a profound hatred for roadside fences.
To the uninitiated, Car Mastery trees look like a constellation of colorful squares promising wheelspins, XP boosts, and the occasional horn sound. But lurking in the branches of five specific donor cars are entire vehicles just begging to be freed. The beauty of this system? It costs zero extra credits. The horror? It demands Skill Points—hundreds of them—earned by chaining drifts, smashing piñatas, and generally treating the Horizon Festival like a demolition derby. A true zen exercise for the patient gamer.
Here is the sacred list of donor cars and the hidden gems they cough up once you’ve sacrificed enough skill points on their altars:
- 2012 Jeep Wrangler Rubicon → 2013 DeBerti Wrangler Unlimited
A modest 50,000 Credits at the Autoshow, this boxy off-roader is your ticket to the far angrier DeBerti creation. Alternatively, it can tumble out of any Wheelspin. Once owned, navigate its skill tree to the far-right node and spend points like you’re buying forgiveness. The DeBerti comes with enough suspension travel to make a monster truck blush.
- 1969 Dodge Charger R/T → 1969 Dodge Charger Daytona HEMI
The R/T costs 103,000 Credits, occasionally appears in Wheelspins, or can be snagged by completing the “Long Gone” Accolade. Unlocking the Daytona feels like excavating a fossil: a colossal rear wing and a nose cone that screams NASCAR nostalgia. Skill points vanish, but the roar of that HEMI is worth every sideways mile.
- 1990 Mazda Savanna RX-7 → 1992 Hoonigan Mazda RX-7 Twerkstallion
You can’t simply buy the Savanna from the Autoshow, which adds a tiny layer of spite. It must be won via Wheelspin or by completing the “Three of a Kind” Accolade. Once secured, the Twerkstallion emerges with Hoonigan livery and tire-shredding charisma. Its skill tree node sits there, smugly, awaiting your drift chains.
- 1995 Porsche 911 GT2 → 1991 Hoonigan Porsche 911 Turbo RWB
At 550,000 Credits, the GT2 is the priciest donor on the list. Wheelspins can also deliver this air-cooled legend. The RWB hidden within is a wide-bodied, wing-clad icon that looks fast even when parked. You’ll need to perform vehicular acrobatics across the map to generate enough skill points, but the result is pure Stuttgart-meets-sideshow.
- 1997 Lamborghini Diablo SV → 1999 Lamborghini Diablo GTR
The Diablo SV goes for 174,000 Credits and is fairly common in Wheelspins. Its skill tree holds the race-bred GTR, a machine that snarls like an offended panther. Unlocking it feels like a heist, except instead of a getaway driver, you’ll be the one doing donuts in a field to max out your skill chain multiplier.
Accumulating Skill Points in 2026 remains a ritual of chaos. Drift Zones are the classic gymnasium; repeat them with a well-tuned drift car and watch the points pile up like dirty laundry. Smashing through the countless destructible items scattered across the map—deck chairs, traffic cones, small trees—adds rapid multipliers. The game’s evolving EventLab creations even offer purpose-built skill parks where you can bounce off ramps and wreckage for minutes on end. Just remember: bank your chain before you hit a solid wall, because the game loves to delete a 500,000-point combo with a single, shameful crash.
One might wonder why, half a decade after launch, Playground Games never made these cars easier to obtain. The answer is likely tradition. Forza titles have long hidden treasures in plain sight, rewarding those who engage with every system. By 2026, the roster has ballooned, yet those five specific bushes still rustle with secrets. Completing the collection without them is like a pizza without cheese—technically still pizza, but why do that to yourself?
So, fire up that trusty 1990 Savanna RX-7, point it toward the nearest drift zone, and let the tire smoke billow. The Twerkstallion awaits. And remember: the real treasure wasn’t the cars we unlocked—it was the hundreds of obliterated fences we left behind.
