FH6 Car Comparison — How to Pick the Better Car Every Time
FH6 has over 800 cars. You can't drive them all, and you definitely can't afford them all without serious credit farming. The difference between buying a car that collects dust in your garage and one that becomes your go-to for an entire class often comes down to 15 seconds spent comparing stats. The problem is the in-game stat bars lie. A full speed bar doesn't tell you if that speed comes from launch acceleration or top-end pull. A handling bar doesn't tell you if the car corners on rails or tries to kill you every time you touch the throttle mid-turn. Here's how to actually compare cars in FH6 — using both the in-game tool and the fh6wiki comparison tool — so you stop buying cars you regret.
How the In-Game Comparison Works
In the Autoshow, any garage menu, or the auction house, press the Compare button (Y on Xbox, Triangle on PS5, C on keyboard default). This brings up a side-by-side view of your current car versus the highlighted car. The game shows you 1-10 stat bars for Speed, Handling, Acceleration, Launch, Braking, and Off-Road, plus the Performance Index number and class letter. You can compare stock vs stock, or your current tuned car vs the stock version of the target car. What you cannot do in-game: compare three cars at once, compare two cars you don't own, or see the underlying numeric values behind those stat bars. Forza uses a 1-10 scale that maps to specific numeric ranges — a Speed 8.2 could be 220 mph or 250 mph, and that 30 mph gap is the difference between winning a highway race and getting walked.
Which Stats Actually Matter (and Which Don't)
The six stat categories are not equally important. Speed and Handling together determine about 80% of a car's performance on pavement. Acceleration matters for tracks with lots of slow corners and short straights — the Guanajuato city circuits reward acceleration more than top speed. Launch matters for drag racing and standing-start events — on a rolling-start circuit race it's nearly irrelevant. Off-Road is the most misleading stat in the game. A car with Off-Road 10 but Handling 4 will feel terrible everywhere. Off-Road stat mostly reflects suspension travel and tire compound, but the game's physics engine cares more about weight distribution and ground clearance. I've won Cross Country events in cars with Off-Road 4 because they were light, balanced, and had the right tire compound. Never buy a car based on its Off-Road number alone. If you're building a rally car, look at the rally car guide instead — it's based on actual stage times, not stat bars.
Braking is the stealth stat that separates good cars from great ones. A car with Braking 9 can brake 30-40 meters later into a corner than a car with Braking 6 at the same speed. On a track with 12 heavy braking zones, that's 4-5 seconds per lap — more than you'll gain from 100 extra horsepower. Look at braking first when comparing cars in the same class.
PI Comparison — Higher Isn't Always Better
Two cars can both be S1 900 PI and perform completely differently. The PI formula in FH6 calculates a weighted composite of power, weight, tire grip, aero, and drivetrain — but it doesn't perfectly capture how those attributes interact. A 900 PI car that spent its PI budget on power upgrades with stock tires will get destroyed by an 875 PI car with race tires and a balanced tune on any track with corners. The PI system also overvalues horsepower relative to handling at higher classes. At A class (800 PI), power and handling are weighted pretty fairly. At S1 (900), horsepower gets overweighted by roughly 15-20%. At S2 (998), the PI system basically throws its hands up — that's why you see cars with 1,200 hp on the S2 leaderboard beating cars with 1,600 hp. The PI number tells you the car's theoretical ceiling in its class. It does not tell you whether the build actually reaches that ceiling.
When comparing, look at PI as a budget spent, not a score earned. A car at 898 PI with race tires, race suspension, and a mild power bump has spent its budget wisely. A car at 900 PI with 1,200 horsepower on street tires is a drag-only build pretending to be an all-rounder.
Comparing Stock vs Tuned
This is the comparison that catches people out. You see a car in the Autoshow with mediocre stats and skip it — but that car might be a monster once upgraded. The best A class cars list is full of cars that look average stock but hit 800 PI beautifully because they have a great chassis and engine swap options. When comparing a potential purchase against your current best-in-class, toggle the view to stock stats for both, not tuned. Stock-to-stock comparison tells you which platform has more potential. A car with Speed 6.8 stock that can take a racing V8 swap has way more ceiling than a car with Speed 7.5 stock that's near its engine's limit. The FH6 Wiki car database shows engine swap options for every car — check that before you drop 2 million credits on something you'll outgrow after 10 hours.
Comparing Cars Across Classes
Comparing a B class car against an S1 class car is usually pointless — they're designed for different kinds of racing. But there's one scenario where cross-class comparison matters: deciding whether to bump a car up a class. Some A class cars make incredible S1 builds with the right upgrades. Some S1 cars actually perform better when detuned to A class because you can add handling upgrades that exceed the class PI ceiling if you leave the engine stock. The comparison tool helps you spot these crossover candidates. Look for cars whose stock PI is within 50 points of a class boundary and whose handling stat is disproportionately high relative to their speed — those are the detune candidates that become class-killers one level down.
Best Comparison Pairs — Start Here
These are the comparisons I make every time I'm buying a new car for a class, and they've saved me millions of credits in bad purchases. Comparing a new hypercar purchase against your current best in class — measure speed/handling/braking gap, if the new car isn't at least 1.0 higher in two of those three categories, skip it. Comparing two cars you're choosing between for a specific race type — build a 5-lap test at your favorite circuit and run both with the same tune philosophy (same tire compound, same weight reduction level, comparable horsepower within 50 hp). Lap times don't lie. Comparing a car you're about to auction against the credits you'll get — check the auction house current prices on fh6wiki before you list. Some cars sell for 5x their Autoshow price because they're seasonal exclusives. Others sell for 20% of Autoshow price because everyone has three of them. Comparing a stock car against its fully upgraded version — always, always do this before starting a build. The upgrade preview screen shows you estimated stats, but the comparison tool with both versions side by side lets you see whether that engine swap is actually worth 150,000 credits in performance gain.
The fh6wiki comparison tool lets you stack up to three cars side by side with full numeric stats — not just the 1-10 bars, but actual top speed in mph, 0-60 times, lateral G ratings, and weight. If you're serious about building the best garage in the game, use both tools together: the in-game comparison for quick Autoshow checks, the wiki comparison for deep dives before a big purchase.
