The GT4 cars in Assetto Corsa Competizione bring a new driving mechanic to the much-loved racing sim. They offer a fun racing experience with lighter and less powerful cars.

But when it comes to picking the best GT4 car for you, it can be tricky. Some cars are much better suited to certain driving styles meaning some players will have much more success than others in a certain car.

But to make the decision of which is the best GT4 car in ACC a bit simpler. I’ve highlighted some key pros and cons about every car, as well as ranking each car from best to worse. As mentioned above, this is my personal opinion, although many of the ACC community share similar thoughts. But you may find some cars better than others. Jump on track with each car to find which GT4 car suits your driving style best!

What Makes The Perfect GT4 Car

Defining the perfect GT4 car can be tricky. Most of the new DLC GT4 cars in ACC have some positives and some negatives. Meaning every car comes with some form of compromise.

GT4 cars in general have much less downforce than their GT3 siblings, which makes for much closer racing overall. To really stand out from the crowd, you need a car which offers either a little bit of everything like the Porsche 718 Cayman. Or a car which really excels in one area with only small compromises elsewhere.

What is the fastest GT4 car in Assetto Corsa Competizione?

Below is every GT4 car in Assetto Corsa Competizione ranked from best to worst from my hours and hours of racing with each car, based on the outright speed around the Nurburgring.

Just a note, my ranking below isn’t based solely on lap time. Some cars perform better on some tracks than others, so I have taken into account other factors such as overall handling, stability, speed and consistency as well as pure lap time.

Fastest straight line speed

Without a shadow of a doubt, if you’re looking for power in the GT4 class, you should look towards the German beast that is the BMW M4 GT4. This is followed closely by the Mercedes-AMG GT4.

The raw performance on offer from the BMW M4 GT4 means this car is extremely competitive on high-speed tracks such as Monza and Paul Ricard.

Its power combined with a good tow down a straight, allows the M4 GT4 to swallow up cars in front with ease. And it’s also a fantastic car to defend with, as it’s much harder for cars to pass on a long straight.

The BMW M4 GT4 isn’t the most agile car, however, meaning it does suffer around tighter circuits. But given a little work on the setup, the BMW M4 GT4 can challenge at most tracks.

Best mid-corner speed

If you’re on a track such as the Hungaroring or Suzuka, and you’re looking for a car which is class-leading in mid-corner speed. Then look no further than the KTM X-Bow GT4.

The KTM X-Bow GT4 is a very unique car. It’s incredibly small, narrow and light, making it a fantastically agile car. In the right hands, the KTM can set stunning sector times through twisty parts of any track and is almost unrivalled in terms of mid-corner grip.

This is especially prevalent in wetter or low-grip conditions. In the rain, the KTM comes alive. Because it has a lot of downforce, even when using a preset setup, it is easily the fastest car in the rain on most tracks.

Its main downfall is certainly its straight line speed. On tracks like Monza and Paul Ricard, the KTM can quickly find itself towards the back of the pack, as faster cars are much stronger on high speed tracks.

Best braking performance

Finding the car with the best braking performance is a trickier category than others that I’ve included. There is a clear winner in terms of out-and-out braking performance but it comes with a huge caveat.

The Porsche 718 Cayman GT4 is a great all round car. But most importantly it’s amazing under braking. When braking in a straight line, not many cars can compete with the Porsche’s stopping power.

However, here comes the caveat. If you try to apply the same braking technique while turning and braking simultaneously, the Porsche has a horrible tendency of lift off oversteer. This is not dissimilar to its bigger brother, the Porsche GT3, however, the effect isn’t quite as strong in the Cayman.

You do have to be very careful when lifting off on a fast corner entry in the 718 Cayman. But once you have setup the car to minimise this effect, the pure braking performance is amazing.

Most stable GT4 car

If you are looking for the absolute most amount of stability you can get from a GT4 car, then you should be looking at the mighty Mercedes-AMG GT4.

The Mercedes-AMG is a car which performs incredibly well in both GT3 and GT4 classes and is somewhat of a fan favourite. It is highly regarded as one of the most stable cars on the GT4 grid, allowing drivers to have full confidence while racing hard.

It’s a car which is also surprisingly nimble, handling quick direction changes well. This combined with its huge amount of torque and power, makes it a great all-round racer. It can handle track elevation change, bumps and kerbs extremely well giving you complete trust that the car will go where you point it.

The only downsides to note are that it’s a little understeer happy. This means you will have to work a little harder to get it turned into slower corners. And it also likes to drink fuel thanks in part to its weight and powerful engine.

The Verdict on the best GT4 car in ACC

On pure lap time alone, the Porsche 718 Cayman GT4 stands above the others as the class leader around Nurburgring. And this trend does continue across other tracks. The Porsche 718 is consistently in the top 3 performers around most tracks.

Is this enough to hold the crown of the best GT4 car in Assetto Corsa Competizione? Well, I’d say it was. The Porsche 718 Cayman certainly isn’t the easiest car to drive. But, with the correct setup, it is consistently one of the fastest.

The Porsche is followed closely by the Audi R8 and the McLaren 570S, which are both also excellent cars. For me, the Audi R8 has a glaring weakness in its braking ability, putting it out of contention for the best GT4 car. But the McLaren is worthy of being in the conversation.

Ultimately, as you can see from my lap times, the car doesn’t make a massive amount of difference. As the majority of lap time comes from the driver. You want to test each car and find one which you feel comfortable driving and one which allows you to push for your fastest personal best lap times.

However, if you are chasing those final tenths of a second, give the Porsche 718 Cayman GT4 a good go.
