GT40 Reimagined Build

Hello everyone,

I’m an engineer with almost 20 years of experience in automotive engineering. I’m also the co-owner of a company that designs and manufactures high-performance gearboxes for electric and hybrid vehicles, including single-speed and two-speed dual-clutch gearboxes. My passion for performance cars, combined with my engineering background, has led me to the idea of building GT40 car.

My initial idea was to buy a replica. However, after researching both original GT40s and modern replicas, I realized that their safety and build standards might not be sufficient in the event of a crash. The GT40—both in its original form and in most replicas—was never designed with modern crash protection in mind. My goal is to change that while preserving the essence of what makes this car special.

Project Overview


I am developing a GT40 replica that retains the car’s legendary looks and performance but with significant improvements in safety and engineering. This isn’t just another kit car; I aim to build a street-legal and track-only version with a strong, integrated safety structure and modern performance components.

Key Features

  • Safety-Focused Chassis – I’m designing a tubular frame with aluminum/carbon fiber monocoque elements around the driver, featuring integrated crumple zones to significantly improve crash safety compared to traditional GT40 replicas.
  • Accurate 3D Chassis Model – I’ve spent around six months, working part-time, to redraw the original GT40 chassis in 3D using existing 2D drawings and real-world measurements.
  • Modern Powertrain – The car could feature a Ford Voodoo/Aluminator V8 paired with, not defined yet, transaxle, delivering the raw, high-revving character of a naturally aspirated supercar.
  • Advanced Driving Aids – The car should integrate ABS and a traction control system, both of which will be adjustable. The level of assistance can be modulated or turned off, giving drivers full control based on their preference and driving conditions.
  • Engineering & Simulation – Using SolidWorks, I plan to run structural and crash simulations to validate the design before building the prototype.
  • Low-Volume Production – My vision is not just a one-off build but a limited-production car that balances heritage with modern engineering.

Welcome Stisljar to GT40S. It sounds like a interesting endeavor. If this project ever materializes, would this be legal in Europe and the UK ?? I see your profile says you are from Croatia. Would it be legal there ??
I will be watching this thread closely. There recently was a company in the US that planned something similar. I don’t think it has launched yet either.

Regards Brian

 
Thanks for the welcome!

Yeah, I'm from Croatia, the goal is to make the car street-legal here. It’s not the easiest process with all the regulations, but I’m thinking about that from the start, especially when it comes to safety. Regarding road legality, Individual Vehicle Approval (IVA) or Small Series Type Approval could be the way to go for me, depending on how things develop.

If you remember the name of that U.S. company doing something similar, I’d love to check them out — always interesting to see how others are approaching the same challenge.

Appreciate you following the build!
 
Maybe gen z?

Cool build, looking forward to following your design process. Not sure what your approach is but i like the idea of having the same experience as one would get from an original car. So rhd with will shifter.

Regarding engine/drivetrain; not sure on regulations in Croatia but here in Norway and Sweden amateur builds are limited to 20kw/100kg. So alot of the modern crate engines and options are ruled out from the start. But too smooth running for my taste anyways...
 
Do you have a line drawing of the side profile of the body with out any inner structure included? I'm trying to figure out the ground clearance height at the front of the wheel arch of the front clam as it relates to the bottom of the front of the rocker. I'm working on positioning the ground clearance height of my front clam before I place the hinge pivots.
