United Racing Design Launches New GTP Pack for Assetto Corsa

United Racing Design has released its new GTP lineup for Assetto Corsa, bringing three modern hybrid prototypes together around its latest generation of physics and electronics simulation. The lineup consists of the Akuma AXR-006, Bayro M Hybrid V8, and the returning Dallas VSR Hybrid.

Translated into their real-world inspirations, that gives Assetto Corsa players versions of the Acura ARX-06, BMW M Hybrid V8, and Cadillac V-Series.R. For anyone building a modern IMSA grid in the original Assetto Corsa, this fills in a pretty important part of the current prototype field.

The Acura and BMW Are the New Additions

The two completely new cars are the Akuma AXR-006 and Bayro M Hybrid V8. Both are priced from €6 individually and have been developed around URD’s newly re-engineered hybrid system.

URD says more than 7,000 lines of configuration and code went into recreating the systems operating underneath these cars. That includes the hybrid MGU, regenerative braking, brake bias compensation, torque sensing, TC1 and TC2, and several other electronic systems that the original Assetto Corsa was never designed to simulate in this level of detail.

There is plenty happening mechanically too. URD lists multi-point tire contact, an advanced tire heating model, detailed aero maps, electric power steering assistance, chassis flex, and five-way adjustable dampers among the features built into the new cars.

The Cadillac Was Already Available

The Dallas VSR Hybrid, URD’s take on the Cadillac V-Series.R, is not actually a new release. That car has been available separately for some time and was already URD’s main entry into the current GTP and LMDh generation.

It was also one of several high-quality Cadillac options available for Assetto Corsa, with Race Sim Studio and Virtual Racing Cars developing their own interpretations of the same car. The arrival of the Acura and BMW therefore matters more than simply adding another prototype.

Instead of having a single URD GTP car sitting by itself, players can now build a much more complete grid using cars created around the same development philosophy.

URD Is Going Deep With the Hybrid Systems

The electronics are probably the most interesting part of these releases. Modern GTP cars depend heavily on hybrid deployment, regenerative braking, traction control, brake blending, and other systems that can be difficult to represent accurately inside a simulator released back in 2014.

Custom Shaders Patch has allowed developers to push well beyond Assetto Corsa’s original physics framework. URD is taking advantage of that heavily here, with the Acura and BMW requiring CSP 0.2.11 or newer.

The cars also support Extended Controls through the CSP App Shelf, allowing many of those additional functions to be mapped properly to a steering wheel. Telemetrick support is included as well for anyone wanting more detailed telemetry recording and analysis.

URD Still Has an Important Place in Assetto Corsa Modding

United Racing Design has been around the Assetto Corsa modding scene for years and remains one of the more established premium developers. Its back catalog includes modern GT3 machinery, GTE cars, prototypes, Super GT-style cars, touring cars, and plenty of older endurance content.

That also puts URD alongside developers such as Race Sim Studio and Virtual Racing Cars at the higher end of the paid Assetto Corsa modding market. All three have increasingly used CSP to build systems that go far beyond what the original simulator supported.

Modern endurance racing has become particularly competitive between these developers. RSS and VRC already offer several current-generation Hypercar and GTP-inspired cars, so URD expanding beyond its Cadillac gives players another serious option for recreating current IMSA racing.

Pricing and Requirements

The new Akuma AXR-006 and Bayro M Hybrid V8 start at €6 each through United Racing Design. The existing Dallas VSR Hybrid remains available separately from €5.

The Acura and BMW require CSP 0.2.11 or newer, and URD recommends a manual installation into the Assetto Corsa directory. Each car also includes documentation explaining the additional systems and controls.

Final Thoughts

The new GTP lineup is a pretty significant expansion for United Racing Design. The Dallas VSR was already a solid option for anyone wanting a Cadillac in Assetto Corsa, but adding Acura and BMW-inspired cars makes the lineup considerably more useful for complete IMSA grids.

The amount of work going into the hybrid and electronics simulation is probably the more interesting part long term. Assetto Corsa is well over a decade old at this point, yet developers such as URD continue finding ways to simulate modern race cars with a level of complexity that would have been impossible when the game originally launched.

For modern prototype fans, there are now three more closely related cars to build a grid around, and considerably more competition at the top end of the Assetto Corsa modding scene.
