What is the fastest GT3 car in ACC?

One of Assetto Corsa Competizione’s greatest strengths is its roster of hyper-realistic cars. With as-real-as-it-gets physics, laser-scanned tracks, and general attention to detail, ACC provides one of the best sim racing experiences available. With so many different cars to choose from, those looking for a competitive edge may want to know which GT3 car on the roster is the quickest.

Before taking a look at the data, it is essential to note that GT3 cars have a pretty healthy Balance of Performance (BoP). If you are unfamiliar with BoP, here is a quick refresher: Balance of Performance is the mechanism by which a wide variety of competing vehicles can compete on a level playing field in any given race.

In short, BoP aims to make every car on the grid competitive. After all, motorsport (whether virtual or not) is meant to highlight the drivers’ ability.

While BoP is excellent, it is not always perfect. In a class like GT3, some cars are going to be inherently faster than others. This performance disparity is due to different car characteristics that may make specific car/track pairs ideal.

Additionally, a lot goes into driving a car fast. The correct setup will go a long way towards reducing lap times. However, the fastest setup may not be the easiest to drive. A more aggressively setup car will often be faster, but getting the most out of that aggressive setup requires a much higher degree of skill and precision from the driver.

With all that background out of the way, Coach Dave Academy is here to help! The team here has worked hard in collecting data while developing setups for different cars. Let’s quickly discuss that data.

Our Data

When Coach Dave Academy develops setups for a new car, we collect all the lap time data. All this data is entered into a spreadsheet, and we are then able to view car performance on a macro scale. By comparing the lap times of different cars across multiple tracks, we can identify the top performers.

For each track, each car with a top-three lap time is awarded points. The most points are awarded for the fastest lap time, less for second fastest, and least for third. In the case of two cars with the same lap time, both cars are awarded the same amount of points. These points are then aggregated for all fifteen tracks, allowing us to rate each car objectively. 

This data will help us answer your burning question, “What is the fastest GT3 car in ACC?”

Porsche 911 II GT3 R


  • Braking
  • Traction
  • Low speed cornering


  • High speed stability
  • Tricky in the wet
  • Late-race understeer

Let’s cut to the chase, the notoriously difficult-to-drive Porsche 911 II GT3 R is the fastest GT3 car in ACC.

Of the fifteen tracks in ACC, the Porsche, using a Coach Dave Academy setup, records the fastest lap time at seven of those tracks.

In addition to having the fastest time at seven tracks, the Porsche also records the second-fastest time at four tracks and the third-fastest time at one. That means that the Porsche is fast enough for a podium at 80% of tracks.

If you are looking for the ultimate edge, it’s time to tame the beast that is the Porsche 911 II GT3 R.

Mercedes AMG GT3


  • Acceleration
  • Very stable in high speed
  • Curb riding


  • Fuel consumption
  • Traction
  • Understeer in low speed corners

Looking for a more stable platform than the Porsche, but one that still can compete at the front of the pack? The Mercedes AMG GT3 is the second fastest GT3 car in ACC.

Using the same data-driven process as we did with the Porsche, the AMG, running the Coach Dave Academy setup, records the fastest lap at five tracks.

In addition to the five fastest track time, the AMG holds the second-fastest lap at two tracks, and the third-fastest at three. If you drive the AMG to its limit, you are looking at a podium at 67% of tracks.

Lamborghini Huracan GT3 EVO


  • Traction
  • Responsive front-end
  • Braking


  • Top speed
  • Twitchy in medium to high speed corners
  • Tire wear (track dependant)

If the Mercedes is not your style, the Lamborghini Huracan is an adequate alternative. 

Despite being quite a ‘peaky’ car, the Lamborghini only holds the fastest lap for one track, but it consistently lays down the second and third-fastest laps. With six second-fastest laps and an additional five third-fastest laps, the Lamborghini is an incredibly consistent performer.

You may not see a lot of race wins driving the Lamborghini on its edge, but it is still a car that is capable of delivering podiums at the same rate as the Porsche.

What else can we use the data for?

Maybe you aren’t the type to commit to one car, but instead, want the fastest car per track. While we can’t just give you our secret sauce, we sure can analyze the data and break down the fastest GT3 cars by track type.

So, let’s do just that. We will use the same data and scoring system we used to determine the overall fastest GT3 cars; however, we will map the results groups containing slow, medium, and fast tracks.

Let’s dive right into it.

Slow Speed Tracks

The six tracks we have grouped into the “slow” category are:

  • Misano
  • Hungaroring
  • Zandvoort
  • Zolder
  • Laguna Seca

For the above tracks, the three fastest cars based on lap time are the Porsche, Mercedes, and Ferrari.

The Porsche absolutely crushes the competition on slow tracks with a 100% podium potential. With one fastest and four second-fastest laps, the Porsche performed fantastically.

If the Porsche is the fastest on slow tracks, the Mercedes is nipping at its heels. The Mercedes has the same podium potential as the Porsche but scores fewer points due to a more distributed placements for fastest lap. With two fastest laps, no second-fastest laps, and three third-fastest laps, it’s a more-than-capable choice.

Rounding out the top three is the ever-fun Ferrari. We love this car, and it is a very competitive option on the slower tracks. With two fastest laps and one second-fastest, the Ferrari has the potential for a podium at 60% of the tracks in this category.

Medium Speed Tracks

The category for medium-speed tracks consists of:

  • Spa
  • Silverstone
  • Barcelona
  • Suzuka
  • Kyalami

As you will start to notice, the Porsche and Mercedes are mainstays on this list. For medium-speed tracks, they see a new addition splitting their placement.

Again, the Porsche leads the pack. Holding the fastest lap time at three tracks, but no second or third-fastest laps still puts it at the top of the list. In this instance, fastest is good enough, but the podium potential suffers, at only 60%.

Splitting the familiar 1-2 combo of Porsche and Mercedes is the Audi. The Audi sports a 100% podium potential across these five tracks. Two fastest laps, one second-fastest lap, and three third-fastest laps, is plenty consistent and good for second.

In an ever-reliable third place is the Mercedes. Much like the Porsche, the Mercedes only has a 60% podium potential. One fastest lap, one second-fastest, and one third-fastest is the consistent competitiveness we have grown to expect from the Mercedes.

High Speed Tracks

The category for high tracks consists of:

The fastest GT3 car on the “fast” tracks all come in with a 67% podium potential. In a bit of a unique twist, there is a tie for the third-fastest car in this category, so you get a bonus car!

For the first time on the list, Mercedes finds itself stepping ahead of the class-leading Porsche. With two fastest lap times, the Mercedes finds itself leading the list on pure pace alone.

In turn, the Porsche pulls a page from the Mercedes book and distributes its points between one fastest lap time and one second-fastest lap time.

Tied for third, we have the Audi and the Lamborghini. Each car has two second-fastest lap times. The only difference between the two is whether you want to be faster at Bathurst or 

Monza, as the cars are otherwise tied at Paul Ricard.

The Verdict

Interestingly, the Porsche and Mercedes stand a fair bit above the rest on pure fastest laps, and then the Lamborghini sneaks in on sheer consistency. 

If we look at the Ferrari 488 GT3, it is right there with the Lamborghini. The Ferrari has four fastest lap times, zero second-fastest, and four third-fastest. The lack of second-fastest lap times causes the Ferrari to lose out to the Lamborghini based on consistency. 

Much like the Ferrari, the Audi R8 LMS GT3 Evo is highly competitive but just doesn’t match the consistency of the Lamborghini. The Audi recorded two fastest laps, three second-fastest, and three third-fastest.

If you have been keeping up with the numbers, you may have noticed that the top three cars have a podium potential above 67%, and then there is a sudden drop off to 50% or below.

To be as competitive as possible, get comfortable with any of the three cars mentioned above. Be sure to run them with the Coach Dave Academy setup, and podiums are in your future.
