LMU Mercedes-AMG GT3 Evo Guide & Setups

Mercedes-Benz has a rich heritage in motor racing, the brand having dominated grand prix competition in multiple spells across the last century, though it’s never had a huge pedigree in sports car racing. It chose to leave the discipline behind following the disastrous 1955 Le Mans 24 Hours, and did so again after its LMP racer decided to turn itself into a plane at the 1999 Le Mans event.  

For 2025, the five-pointed star made a welcome return to Le Mans and the World Endurance Championship with its AMG-GT3 Evo challenger. As Le Mans Ultimate has now reached long-awaited 1.0 status, the Merc makes its debut in the title. This guide will run you through everything you need to know about the car. 

The AMG GT3 Evo Is One Of The Most Trusted GT3 Machines On The Planet

Since the AMG GT3 Evo was introduced for the 2020 motorsport season, it has taken over from its predecessor as one of the most popular GT3 vehicles in the world. It competes in pretty much every international and domestic GT championship, and has proven an effective tool in the hands of professional and amateur drivers alike, thanks to its approachable handling balance. Various titles in series like GT Challenge Europe, DTM, and IMSA illustrate this. 

The AMG-GT3 joined the prestigious WEC grid for the first time in 2025 under the stewardship of established Italian team Iron Lynx, which had run Lamborghini’s Hypercar and LMGT3 programs in 2024. The AMG GT3 Evo was altered to run in LMGT3 spec, with the changes essentially reducing power and downforce when compared to its normal GT3 form. 

The car has shown flashes of speed so far in 2025, but has yet to score the results it achieves in other series. Its best result so far is eighth at the 24 Hours of Le Mans, but the vehicle is becoming more and more competitive as Iron Lynx gets its head around its new toy.  

Car Specifications & Key Features

The AMG GT3 Evo is one of several LMGT3 vehicles to have its engine mounted at the front of the car, which helps to afford it natural stability. The powerplant in question is a naturally aspirated V8, which produces up to 671 hp depending on the Balance Of Performance measures levelled against it. It’s connected to the rear wheels via a six-speed sequential transmission. 

The AMG GT3 Evo is built to extreme accuracy by Le Mans Ultimate’s developers, with the car emitting a similarly throaty V8 engine note as in real life and boasting an exquisitely modelled cockpit. It also features all the changes that set it apart from its standard GT3 sibling, as LMGT3 cars work to a different set of values than normal GT3 machines. 

For starters, the AMG GT3 Evo LMGT3 produces less power than the standard car due to the BOP parameters the ACO uses when compared to the SRO, which runs the vast majority of GT3 series around the world. The ACO also requires each car to utilize a tweaked aero package, which reduces peak downforce when compared to normal GT3 challengers, and reduces cornering speeds.

• The biggest difference is that the AMG LMGT3’s fuel usage is governed by its Virtual Energy value, which is monitored via a torque sensor mounted to the driveshaft
• Virtual Energy ensures that each LMGT3 racer will use a similar amount of fuel during a stint, meaning no car will have any kind of advantage or disadvantage when it comes to fuel efficiency
• This acts as a BOP measure, and prevents certain cars from being able to extend their fuel stints longer than their competitors, which would allow them to take less fuel and save time at each stop, or potentially even reduce the number of stops they have to make during a race  

Handling & Performance on Track

When jumping behind the wheel of the Mercedes AMG LMGT3, you’ll find that it tends to offer approachable and stable handling from the outset, mainly due to that big V8 out front pushing the front axle on. When overdriving, it is possible to get the rear end to snap out, as it’s set up to help rotate the front as much as possible to reduce understeer, while also not affecting stability under the limit. 

The AMG LMGT3 has a superb aero package that produces an impressive amount of downforce when compared to its rivals, which means you can carry impressive amounts of speed through medium and high-speed turns. Making sure you get the car setup correctly on corner entry is imperative in this case, as you want to ensure you don’t compromise its aero platform by changing the car’s attack angle too aggressively mid-corner so that you can make the most of the vehicle’s downforce. 

Traction is strong due to the balanced power delivery of the naturally aspirated engine, as well as the vehicle’s well-optimized traction control system. 

• The AMG LMGT3 is stable under heavy braking, but ensure to trailbrake to make sure you reduce the likelihood of understeer on corner entry
• High downforce level not only boosts high-speed stability, but also helps to look after tires across longer stints
• As with all LMGT3 cars, the AMG-GT3 Evo has less downforce and power than cars running to normal GT3 regulations

Best Tracks for the Mercedes-AMG GT3 Evo in Le Mans Ultimate

The AMG GT3 Evo’s effective aero package means it’s a tough challenger at tracks with more high-speed cornering sections in LMU, such as Spa Francorchamps and Lusail. It is also stable across kerbs, which further enhances its abilities at these sorts of venues.      

• The AMG GT3 Evo performs well at high-speed circuits like Spa, as well as the upcoming Silverstone and Barcelona layouts
• Tracks with slower and twistier sections will prove trickier due to the AMG having to wrestle its heavy V8 around when changing directions, making venues like Monza potentially weaker for it
• Its inherent stability ensures it’s an approachable choice in wet conditions, especially for less experienced racers

How It Compares to Other Cars in the Class

The AMG GT3 Evo drives pretty similarly to other front-engined LMGT3 vehicles in LMU, though its larger engine can cause it to understeer more readily at slow speeds than challengers with more compact units, which helps provide a more even weight distribution. Its high-speed downforce levels make it difficult to beat in fast bends, though, even when compared to more naturally balanced mid-engined contenders like the Ferrari 296 GT3 and the Lamborghini Huracan GT3 Evo 2. 

• Stability and consistency make it similar to other front-engined cars already featured in LMU, though its peak downforce levels make it particularly strong in mid and high-speed bends compared to its close rivals
• It lacks the slow-speed agility of mid-engined options, though it will pay you back in terms of overall stability 

Drivers who like to carry big corner speed, rather than park on the apex and drive out straight, will get on well with the AMG GT3 Evo, as its sophisticated aero setup means this is the best way to extract laptime from it. This makes it a great choice for less experienced drivers who want the corner speed benefits of a mid-engined car, but the stability of a front-engined one. Just remember that you’ll tend to pay the price in slower turns.

Final Verdict: Is the Mercedes-AMG GT3 Evo the Right Choice for You?

Drivers who enjoy piloting a car that remains stable and nicely in line through all stages of the corner will relish steering the AMG GT3 Evo, the car being an excellent prospect for drivers who are less experienced or who don’t enjoy the car moving around beneath them. 

Its smooth V8 means it won’t land any nasty surprises on your lap when accelerating from corners, while its mid and high-speed cornering prowess mean that those who like to make laptime by carrying as much corner speed as possible will get on well with it. 

Drivers after a car that naturally moves around beneath them and rotates more through slower bends will be better suited to cars like the Ferrari 296, Lamborghini Huracan Evo 2, or the McLaren 720s GT3 Evo.

Wrapping Up

The AMG GT3 Evo provides LMU drivers with an approachable and effective weapon on a variety of circuits, especially for those who like a more planted feel beneath them. This also makes it an excellent option for those looking to tackle longer races, especially when you need to think about racing in different weather conditions and preserving tyres.
