iRacing has been working hard over the months and years to bolster its GTP prototype class within the service, with no less than five cars currently making up the class. The category includes all four LMDh specification machines that run in the real-life IMSA Sports Car Championship, as well as the Ferrari 499P LMH that runs in the World Endurance Championship.
As of iRacing’s 2026 Season 4 update, there will now be a sixth contender for you to take on and pilot yourself. The machine in question is the Aston Martin Valkyrie AMR-LMH, the final car that currently competes in IMSA, which means the full grid of GTPs will now be usable within iRacing.
This guide will run you through the ins and outs of the British bruiser, where you’ll be able to test out its racing mettle within the sim, with some tips, tricks and setups thrown in.
New Aston Martin Valkyrie AMR-LMH in iRacing
The Valkyrie AMR-LMH’s history stretches back to 2019, which was when the car was set to compete as part of the all-new Hypercar category that would become the pinnacle class within the WEC. Based on the road-going track car of the same name, the Valkyrie AMR-LMH project would ultimately be shelved as the manufacturer focused on entering Formula 1 instead.
Heart of Racing Steps In
After a four-year slumber, the Valkyrie LMH program was resurrected. The change of heart came primarily thanks to a racing operation called Heart of Racing. Wanting to compete in both the WEC and the North American IMSA Series with the car, HOR struck a deal with Aston to complete development of the machine before racing it. The finished car would ultimately make its WEC debut at the start of the 2025 season in February of that year, at the Qatar 1000km.
Its IMSA bow would come just a couple of weeks later, at the Sebring 12 Hours. HOR struggled to match the established Hypercar/GTP contenders early on, though continual learning saw the car get quicker as the year went on. Ultimately, a best WEC result of fifth would be achieved in the 6 Hours of Fuji, while its first podium finish would come in the season-ending IMSA Petit Le Mans at Road Atlanta. Having looked to be the quickest car out there for most of the race, the sole Valkyrie in the field would ultimately come home second.
The Valkyrie has proven to be more competitive across the board so far in 2026, at the time of writing, with its best result being fourth at Spa in WEC, and fifth at Road America during its IMSA campaign.
Aston Martin Valkyrie LMH Price
As far as the iRacing version goes, it’ll cost the usual $11.95 as a one-time purchase, just like the other GTP offerings do. It’s safe to say that’s a fair amount cheaper than the real version would demand from your bank account.

No Hybrid System For The Valkyrie
As hinted at by its name, the Valkyrie AMR-LMH is built to the WEC-focused LMH regulations, rather than the more universally adopted LMDh ruleset. This means that rather than using an LMP2 chassis from one of the four registered constructors, the Valkyrie instead uses a bespoke chassis borrowed from the track racer.
It is unique from the other LMH cars that currently race, though, as the Valkyrie doesn’t feature any form of hybrid system, as Aston wanted to save weight and reduce the complexity of the design.
Instead, the Valkyrie weighs in with a glorious naturally aspirated 6.5-litre V12 engine, which is mounted behind the driver in the middle of the car. Like its rivals, the engine sends around 670 horsepower to the rear wheels via a seven-speed semi-automatic transmission.
Thanks to the virtual energy balancing measures established by the WEC and IMSA, the lack of a hybrid doesn’t have an effect on the total distance the car can run versus its theoretically more efficient competitors.
Being a hypercar, it essentially handles like a GTE racer with extra power and downforce. This means it can feel quite cumbersome in slower and tighter sections of track, though its bespoke chassis and lack of rear-mounted hybrid system make it a little more stable at high speed when compared to its LMDh rivals.
Where To Race The New Aston Martin Valkyrie AMR-LMH
Being a part of the GTP class, the Valkyrie AMR-LMH is eligible to race in any series that allows the particular category to participate. As a result, drivers wanting to run it will need a Sports Car B licence at the minimum, which will allow them to campaign in the likes of the Prototype Challenge, which is a fixed-setup series that runs races over 20 minutes every day of the week, and every two hours.
You can also enter endurance-style races at B level, with these races being a part of the IMSA Endurance Series and Global Endurance Tour. While the former runs on weekends over a length of 160 minutes, the latter is run over the weekend over a much longer duration of 1440 minutes, replicating a real-life 24-hour encounter.
And then we get to the big leagues of A-Class sports car competition. Here, you can take on the IMSA iRacing Open Series, which allows you to take on 45-minute contests seven days a week, again with each session starting at two-hour intervals. There is no limit on the setup changes you can make here, allowing you to flex your engineering muscles. Alongside this, there is the IMSA iRacing Series Fixed, which allows you to run 35-minute races with a fixed setup.
Final Thoughts
The addition of the Aston Martin Valkyrie AMR-LMH adds further variety to the already-varied GTP class within iRacing, and we reckon the machine will be a hugely popular addition. Not only does it look wildly different from the other GTP weapons on offer, but its soulful V12 powerplant ensures it also stands out from the rest.

Given the lack of extra weight at the rear of the car, as well as the differing characteristics of its engine, it also provides a unique driving experience versus the other GTPs available. Plus, for those authenticity enthusiasts out there, you can now race against the complete grid of GTPs that race alongside each other in the real-life IMSA Series.
Whatever you think of the newest GTP beast to call iRacing home, the Cadillac V-Series.R certainly has its work cut out for it to remain the king when it comes to engine noise.
