The Indianapolis road course is two tracks in one. A very long straight, and a flat, tight infield.
The Ferrari 296 GT3 is the reference car. The Ford Mustang GT3 and the Lamborghini Huracan GT3 EVO2 are tied 4 kg behind. The Audi R8 LMS GT3 Evo II is 7 kg off.
It is a close table. The first seven cars are inside 13 kg.
The lap itself, corner by corner, is in my Indianapolis road course track guide. If setups are new to you, read the ACC setup guide first. The car choice matters less than getting the pressures right.

The numbers come from Full Grip Motorsport's BoP for Indianapolis road course, read on 5 October 2026. It is a league balance built from hotlap pace, not the official one in the game.
It works with ballast. The quickest car at each track is the reference at 0 kg. Every other car runs lighter to keep up. The more weight a car has taken off, the further it is from the pace there. I only show their top five. The full table is on their site.
Two cars tied for second, 4 kg off. Indianapolis has a favourite but no runaway.
1. Ferrari 296 GT3
Most of the lap time at Indianapolis is in the infield. It is a run of slow and medium corners with no banking and no elevation, so the car has only its own grip to work with.
The 296 rotates well at low speed and it is gentle on its rear tyres on the way out. That covers the infield.
It is not the fastest car on the main straight. It does not need to be. The infield is longer than it looks.
2. Ford Mustang GT3
The straight car. The run past the pits is one of the longest full throttle stretches in the game and the Mustang makes the most of it.
Then it is stable into turn 1, which is the biggest stop of the lap. For racing here it is the one I would pick.
3. Lamborghini Huracan GT3 EVO2
Level with the Mustang and the opposite kind of car. It makes its time in the infield with quick changes of direction and gives some back on the straight.
Other cars that work at Indianapolis
- Audi R8 LMS GT3 Evo II (-7 kg). Seven kilos off. Like the Huracan, it is at home in the infield.
- Mercedes-AMG GT3 Evo (-10 kg). Good traction out of the slow corners and happy over the infield kerbs. Ten kilos off.
- Aston Martin V8 Vantage GT3 (-11 kg). Stable into turn 1 and the chicane at the end of the back straight. Easy to drive and in the base game.
What Indianapolis rewards
A compromise. You cannot have everything here.
The road course runs the main straight of the oval in the opposite direction, then turns right into the infield. Turn 1 is a hard stop from top speed, and on lap one it is a crowded one.
The infield is flat. Slow corners, short bursts, a back straight with a chicane at the end, then more slow corners before you come back onto the oval.
So you choose. Low wing for the straight, and the car slides in the infield. High wing for the infield, and you get passed on the straight.
A car that makes mechanical grip, that turns without needing the wing, lets you run less of it. That is the key to this track.
The surface changes too. The infield and the oval sections do not have the same grip. Feel for it in practice.
What the pro drivers say
Coach Dave Academy asked its pro drivers to rank the GT3 cars in April 2026. They do not name a specialist for Indianapolis, but they put the Ford Mustang GT3 first everywhere, with the Mercedes-AMG GT3 Evo and the McLaren 720S GT3 Evo behind it.
Full Grip has the Mustang second here, at -4 kg. So the two do not fully agree. One is pro drivers judging a car over a race distance on the official balance. The other is hotlap pace turned into ballast for a league. Different questions, different answers.
The best car for beginners at Indianapolis
The Ford Mustang GT3. It is 4 kg off the reference, free and stable under braking. Turn 1 is where beginners lose it here, and the Mustang is calm there.
If you own the 2023 pack, the Ferrari 296 is just as friendly and a touch quicker.
Sprint races and endurance races
The slipstream is strong on a straight this long. The car behind arrives at turn 1 with a big speed advantage, so leading onto the straight is not always what you want on the last lap.
In a sprint race I would take the Mustang. It passes on the straight and defends there too.
In a long race the rear tyres wear in the infield and the brakes work hard at turn 1. The Ferrari is the safer choice for a stint.
Mind the wall on the exit of the last corner. It is a real wall.
Pick the car you know
Indianapolis is a setup track as much as a car track. The right wing level is worth more than the 4 kg between the top three. If you are still choosing, I go through the whole class in the fastest GT3 cars in ACC and through the way I would decide in how to choose a car in ACC.

FAQ
What is the fastest car at Indianapolis in ACC?
In Full Grip Motorsport's track by track BoP, read on 5 October 2026, it is the Ferrari 296 GT3, with the Ford Mustang GT3 next at -4 kg. That is league data built from hotlap pace, not an official ranking.
Is the Ford Mustang GT3 the best car at Indianapolis?
Not in Full Grip's data. It sits second here at -4 kg. Coach Dave's pro drivers still rate it the fastest GT3 car across the game, so it is never a bad choice. It is just not the standout at Indianapolis.
What is the best car for beginners at Indianapolis?
The Ford Mustang GT3. It is free, stable under braking and only 4 kg off the reference. If you own the 2023 GT World Challenge Pack, the Ferrari 296 GT3 is just as friendly.
How much wing should I run at Indianapolis in ACC?
Less than the infield makes you want. Start in the middle of the range, then take wing off one step at a time until the car becomes hard to drive in the infield. Go back one step from there.
Does ACC have the Indianapolis oval?
No. ACC has the road course, which uses the main straight of the oval in the opposite direction and then runs through the infield.
Do I need DLC to race at Indianapolis?
Yes. It comes in the American Track Pack, together with two other American circuits.
Does the balance of performance change from track to track?
Yes. ACC uses a different balance for each circuit, which is why the fastest car is not the same everywhere. Leagues such as Full Grip Motorsport and Low Fuel Motorsport can run their own custom BoP on top of that.
