As sports car racing has grown in popularity over the last few years, most sim racing titles have worked hard to incorporate as many prototype and GT race cars into their vehicle rosters as they can get their hands on.
With a wide range of driving experiences, looks, and engine sounds that work to create close and thrilling racing, sim racers the world over have fallen in love with contemporary sports car competition.
The current top class of prototype racing is run to LMDh/GTP regulations, and half a dozen of these models have been added to AMS2 over the last year or so. Coach Dave Academy decided to craft a guide looking at the current list and what you can expect when jumping behind the wheel.
If you’re new to AMS2 and need some assistance getting everything set up, then why not check out Coach Dave Academy’s in-depth beginner guide for the title.
LMDh/GTP Has Paved the Way For A New Golden Era Of Endurance Racing
With the World Endurance Championship and the IMSA SportsCar Series struggling to attract entries to its top-flight prototype contingent, LMP1 and DPi, respectively, it was time for a change. While both came up with new rulesets, LMH and LMDh, the decision was made to balance performance between the two to ensure manufacturers could enter the same car in both series.
This approach proved to be genius, with 13 official vehicle manufacturers having signed up to take part thus far, alongside a few smaller brands in the WEC like Glickenhaus and Isotta Fraschini. With each car governed by Balance of Performance, fans have flocked to enjoy the resulting close racing, allowing sports car racing to enjoy a huge burst in popularity.
Sim racers have been hungry to get their hands on these vehicles, which feature wildly different powertrains and external designs. These differences give each car a distinct personality, much is the case in the slower GT3 class. While LMDh cars are built on LMP2 chassis and feature a spec hybrid system alongside whichever engine and body the constructor wants, LMH cars are built using bespoke chassis and hybrid systems.
LMDh/GTP Cars in AMS2
There are currently six LMDh/GTP models available in AMS2, meaning only one IMSA GTP racer, the Acura ARX-06, is missing as of August 2025.
All six cars came to the title as DLC, with the half-dozen machines shared between four different content packs. While most are built to LMDh regulations, the newest addition to the platform, the Aston Martin Valkyrie, is built to LMH regulations, though it doesn’t feature any kind of hybrid powertrain that its rivals do.
Most are designated GTP vehicles due to being involved in IMSA, though the Alpine is labelled as an LMDh due to only taking part in the WEC.
To purchase any of the AMS2 DLCs, look here.
Endurance Pack Part 1
AMS2’s maiden endurance-focused car pack brought the first three GTP racers into the title when it arrived in January 2024, alongside some GT3 challengers.
- BMW M Hybrid V8 GTP
- Cadillac V-Series.R GTP
- Porsche 963 GTP
Endurance Pack Part 2
The fourth LMDh launched into AMS2 came as part of the second of three Endurance Packs currently released for the sim. It made its debut in March 2025, and also featured a pair of LMP2 machines and a trio of GT3 racers.
- Alpine A424 LMDh
Endurance Pack Part 3
Aston Martin’s Valkyrie is the latest addition to AMS2’s prototype ranks, the car coming as part of the third Endurance Pack in July 2025. It made its debut alongside the British brands GT contenders, past and present.
- Aston Martin Valkyrie GTP
Lamborghini Dream Pack Part 1
The set-to-be-retired SC63 GTP came to AMS2 as part of the Lamborghini-geared content update in November 2024, alongside several of the Italian marque’s GT racing challengers.

Alpine A424
| Car | Ruleset | Engine |
| Alpine A424 | LMDh | 3.4 Litre Turbo V6 |
Alpine, a subsidiary of Renault, used to be heavily involved in racing during the mid-20th century. These days, the performance brand is involved primarily in Formula 1 and the WEC, with the latter involving its A424 prototype. The vehicle is built upon an Oreca LMP2 chassis, and uses a Mechachrome-designed turbocharged V6 engine.
The A424 tends to understeer once pushed, though this can be dialled out with a bit of tuning. For the most part, the car is very effective through the fast corners, and when tuned right, is also agile through slower bends. It’s not particularly amazing other kerbs, but it won’t kill you if you attack them either.
Aston Martin Valkyrie Hypercar
| Car | Ruleset | Engine |
| Aston Martin Valkyrie Hypercar | GTP | 6.5 Litre Naturally Aspirated V12 |
Having competed at the front of GT racing continuously since 2006, Aston Martin elected to rejoin top-flight prototype racing with a racing version of its Valkyrie track car for the 2025 season. Competing in both the WEC and IMSA, the vehicle has won over fans thanks to its screaming naturally aspirated V12 engine and striking looks.
Due to a lack of a hybrid system, it isn’t as efficient as its rivals. You’ll have to focus on saving more energy over a stint to match the other cars as a result, though its impressive straight-line speed will help keep you ahead. The Valkyrie is pretty front-heavy, ensuring it tends to understeer through the bends, so carrying too much entry speed will be detrimental to your laptimes.
It can also be a little snappy over kerbs, making finding a middle ground tough at times, but very satisfying when you do so.
BMW M Hybrid V8
| Car | Ruleset | Engine |
| BMW M Hybrid V8 | GTP | 4.0 Litre Turbo V8 |
Having won the 1999 24 Hours of Le Mans with its V12 LMR prototype, BMW knows how to build a top-flight sports car. It elected to join the LMDh fray with its M Hybrid V8, which uses a Dallara LMP2 chassis as its basis. The iconic BMW kidney grilles ensure the vehicle is unmistakable as one of the German brand’s steeds when out on track, while its typically efficient turbocharged V8 promises power and durability.
The M Hybrid V8 offers a safe handling balance, with the nose tending to push on through the corners unless you purposefully kick the back end out with some aggressive steering input. The BMW is well-suited to beginners due to this, as it is pretty easy to set strong times soon after jumping behind the wheel.
Cadillac V-Series.R
| Car | Ruleset | Engine |
| Cadillac V-Series.R | GTP | 5.5 Litre Naturally Aspirated V8 |
The Cadillac V-Series.R is another of the fan favourite LMDh’s, even if it doesn’t stand out particularly from a styling standpoint. Its NA 5.5-litre V8 certainly does though, with its muscular note reverberating around any grandstand within earshot.
On track, that V8 doesn’t just sound great, but it also offers up a crisp throttle response that ensures you get decent grip on acceleration. The V-Series.R has a neutral handling balance, though it can snap on occasion if you’re not careful, which ensures it can be a little more challenging to get the most from if you’re less experienced with this type of machinery.
Lamborghini SC63
| Car | Ruleset | Engine |
| Lamborghini SC63 | GTP | 3.8 Litre Twin-Turbo V8 |
The Lamborghini SC63 is the only LMDh car built upon Ligier’s LMP2 chassis, and you can feel a difference when compared to its rivals out on circuit. The 3.8-liter twin-turbo V8 is docile enough when you get on power, but the car feels heavier through corners.
The nose tends to push on as a result, which means you’ll have to work harder to get it through with some pace. It’s not particularly scary to drive, but that understeer makes the Lambo trickier to extract a strong laptime out of. Rear traction is OK, so with a bit of tuning, the car has some potential.
Porsche 963
| Car | Ruleset | Engine |
| Porsche 963 | GTP | 4.6 litre Turbo V8 |
The Porsche 963, built upon an LMP2 chassis provided by Multimatic, is one of the most successful LMDh cars built to date. The car claimed both the WEC and IMSA drivers’ titles in 2024, as well as the manufacturers’ crown in the latter. With a turbocharged 4.6-liter V8 on hand, which has its origins from the German marque’s ultra-successful RS Spyder LMP2 racer from the 2000s as well as its hybrid 918 road car, you can feel the vehicle’s pedigree as soon as you jump behind the wheel.
The 963 is easy to drive quickly from the outset, with the car offering a balance that angles more towards understeer. It’s not too egregious though, with its exceptional rear-end stability and traction allowing you to drive through corners beautifully. This makes it easy to carry momentum and speed, which helps with laptimes. As a result, the 963 is the best option for beginners looking to get up to speed with GTP machinery as quickly as possible.
Final Thoughts
The GTPs are certainly trickier than the GT3 class racers to get up to speed with, given their high-speed but heavy nature. They’re ultra rewarding once you figure them out, so it’s best to get on track for yourself to find your favourite.
