#Forza motorsport 4 unicorn cars install#
However, this allows players to then install huge engines, or cut weight from the rest of the car. Due to how Motorsport 3 calculates a car's Performance Index (in other words, how "fast" a car is going around a track), All-wheel-drive drivetrains cause your performance index to actually go down, since it adds about a hundred pounds to the car.Usually this is the stomping ground of Peugeot and Renault hatchbacks, but things get interesting if you're bastard enough to bring a Bugatti, or even more, a Peugeot 908 LM! Even better, at driver level 20 the game gives you a Veyron for free. An example, the French Elite Invitational in Motorsport 3. Things can get deliciously broken when you take a car that technically qualifies for a given race but which no human judge would allow entry.In a sense, modification, as in Forza Motorsport 3 and previous games, the AI never has upgraded cars.The Honda CRX in the first game falls into this due to improperly set drag values.The Aston Martin DBR9, Alfa Romeo 33 Stradale, Shelby Cobra Daytona, Ford GT (new and old), McLaren F1, Ferrari 250 GTO and Porsche 906 have consistenly been strong cars on almost every game they appeared.Another example are all kinds of upgrades (such as AWD swaps, installing centrifugal chargers or increasing the tire width) that substract PI instead of increasing it.
#Forza motorsport 4 unicorn cars serial numbers#
An example is Chevrolet's LS3 engine (Which has been given Serial Numbers Filed Off treatment and appears as simply the "6.2L V8") in Horizon 3 and 4, which is considered a PI-efficient engine. The PI system is not a perfect one: for instance, two cars with very similar power (and torque)-to-weight ratios could have different PIs just because the engines are different.The strongest examples are easily Audis, Mitsubishis, Subarus, Fords and especially Lamborghinis, which usually have some of the best cars in the game. In Forza Motorsport 2, only manufacturers with AWD cars could allow AWD swaps, and even then they are only included in specific engine swaps, but future games would open the swap to almost every other car (with hybrids and electrics being some of the exceptions). Vehicles with AWD often delve into this, due to the lateral grip bonus and an amazing launch.
