PLANO, TX, July 1, 2025 – Siemens Digital Industries Software has announced that Briggs Automotive Company (BAC) will move to the Siemens Xcelerator portfolio and use it to develop the next generation of Mono, its single-seater road legal race car.
The BAC Mono, designed for both road and track, is a single-seat vehicle with a weight of 570 kg. It uses 2.5-liter engine that produces 311 hp and 313 Nm of torque. This results in a power-to-weight ratio of 546 hp-per-ton.
BAC’s lightweight structure, combining graphene-infused carbon panels and balanced weight distribution, enables the Mono to accelerate from 0 to 60 mph in 2.7 seconds. To improve performance in future models and for the development of its next generation Mono, BAC has selected NX X from Siemens’ Designcenter suite of product engineering software.
“Anything that helps us be ahead of the game and be ahead of anybody else. The reason we chose Siemens’ Designcenter software to develop the next generation of Mono is because it’s the best – and it gives us the tools we need to take our vision to the next level,” said Ian Briggs, design director and co-founder. “Our vision was to create a car that simply didn’t exist. The fundamental principle of a sports car is choosing excitement over utility, and we took that to the nth degree. Mono is that philosophy made real – a vehicle without compromise, built to prove that being ahead of the game means refusing to compromise on the driving experience.”
Solving the challenge of homologation
One of the key drivers for the move to Designcenter is to solve the challenge serving a global customer base and certifying that a vehicle complies with the regulatory and safety standards of a country.
As Briggs explains, “A key challenge for us is homologating the car for the global market. Understanding the specific positional requirements for everything from headlights to driver sight lines is a complex minefield. The great advantage of Designcenter is that it allows us to build that entire regulatory framework directly into our 3D CAD model, giving us new levels of confidence and a greater speed of development.”
Customer experience with Immersive Design
The BAC team is also exploring ways to enhance the customer buying and customization experience with Siemens’ engineering technology – enabling customers to use immersive XR technology to experience their bespoke vehicles – based on 3D CAD data, presented in high-fidelity realism.
Eliott Marshall, production manager, BAC explains, “The thing that makes BAC truly unique is the bespoke elements. Siemens’ Immersive Engineering technology allows us to present to the customer exactly what they’re ordering. Being able to sit in their seat fitting jig and see all of the personal customizations they want around them, interact with them as if they’re already implemented, is going to get the fire burning within them.”
