The McLaren Senna and the Aston Martin Valkyrie are British hypercars performing exceptionally well not just on the road, but also on the track. With its track-only equivalents roaring in the Forza Motorsport game, it's time to exploit them further.
How do these two hypercar-turned-track weapons differentiate themselves? Let's begin with the McLaren Senna GTR, the track-only version of the King of McLaren Ultimate Series.
Revealed as a concept in 2018 and spawned into a limited-production model moments later, the Senna GTR transforms the already track-proven hypercar with even more potential.
The 4.0L V8 twin-turbo engine from its road-going equivalent remains the same, meaning it still produces 814hp of power, but it's mated to a racing transmission McLaren says it's faster in a straight line compared to the normal Senna.
In addition to its race-tuned aerodynamics that generate 1000kg of downforce, the Senna GT-R comes with a revised double wishbone suspension and slick Pirelli tires for improved grip.
The track-only Senna GT-R is limited to 75 units sold.
Now, let's get to know the Aston Martin Valkyrie AMR Pro, the closest thing you can get from a Formula 1 car.
Based on the Valkyrie hypercar, the AMR Pro is a track-only version that delivers the same performance and dynamics just like a Formula 1 car.
In addition to its more aggressive aerodynamic upgrades that add more dimension compared to the normal Valkyrie, making it capable of achieving lateral acceleration of more than 3G, the AMR Pro ditches the Valkyrie's hybrid system, trading power for weight loss. The 6.5L Cosworth V12 NA engine remains, producing over 1000PS of power.
During testing, the Valkyrie AMR Pro lapped the Le Mans circuit in 3 minutes 20 seconds, delivering the same performance as an LMP1-class race car.
Only 40 were made and sold. Customers who bought the Valkyrie AMR Pro have gained access to a bespoke track day experience at select FIA-approved circuits worldwide as well as other privileges.
To bring out the anger of the beast from these two track versions of British hypercars, I'm heading to Silverstone and find out which of them is the superior king. Let's roll the tapes.
And now, the results...
Senna GTR - 2m11.792s
Valkyrie AMR Pro - 1m52.599s
Thanks to its F1 know-how carried over from its road-legal equivalent as well as other track-based improvements, the Valkyrie AMR Pro massively sliced the Senna GTR into bits around Silverstone.
Regardless of today's result, I'm extremely satisfied that the Senna GTR and the Valkyrie AMR Pro are truly at home in the new Forza Motorsport game because this game served as a chance to demonstrate their de-restricted track capabilities against the world's most demanding race tracks.
Come try Britain's most extreme track weapons in Forza Motorsport if you're brave enough. You're welcome to do so.
