The latest developments on the Ligero prototype build have been work around the cockpit area. Will and the team at Joe Bradley Fibreglass have created a mould for the windscreen surround of the donor Boxster for use in the Ligero. The rationale behind this is to be able to use a Boxster windscreen rather than custom glass, with the added benefit of the Boxster windscreen having the rearview mirror attached, thus solving that problem as well. The mould and initial part came out fantastically.
Next step was to start positioning the windscreen surround to get the angles right for the driving position as well as the roofline. The wooden frame in the following photos can be seen to allow adjustment of the windscreen positioning. Once the right angle and height were achieved, the angles and dimensions for the supporting metalwork could be determined – which will be the next phase of the build and will then in turn dictate the roof structure.
In keeping with the theme of using as many donor parts from the Boxster as possible, the dash from the Porsche has also been transplanted. The goal here is to create a space frame for the Ligero with the exact mounting points found on the front firewall of the Boxster to allow the dash assembly to be relatively simply plugged in to it.
Other ongoing work has been the transplant of the Boxster steering rack. The length of the rack is significantly shorter in our application, however we’re hoping that a simple cutting and shortening of the column splines should work.
An updated video walk around of the prototype can be found at Delta’s Youtube channel.
I’m also excited to report that I’ve secured a power plant for the prototype. The initial plan was to use the Boxster drive chain for this prototype and then evolve the car to have more horsepower for the next build. Owing to the fact that we had initially built the engine bay to house an AMG 5.5L V8, it turned out to be too narrow to fit the Boxster flat 6. Rather than butcher the engine bay I decided to jump straight to the V8 evolution of the car for this initial build. The engine I’ve purchased is an LS3 from a worked HSV which is rated to around 550hp and well over 700nm torque! The plan is to mate it to a Boxster S transaxle through a custom adapter plate and clutch. I think that 550hp will well and truly get the car going as well as it looks like it should.
Thanks for following. Cheers, dan

The team have been working hard on transplanting the dash from the Boxster into the Ligero prototype. Those of you who have been following the build for a while will know that we were initially planning to use a Mercedes AMG mid clip grafted onto the space frame as a solution for the dash and windscreen. As much as that would have simplified the build, we couldn’t get a driving position that we were happy with due to lack of cabin space, and furthermore it wasn’t going to be reproducible for potential future cars. In the following photos it can be seen that clamps are holding the dash in place whilst it is adjusted to get the position just right for the driver, as well as for the windscreen angle, which will subsequently drive the roof build.
Once the dash and windscreen position has been determined it will be possible to finalise the plug for the front clip and then start the mould creation for the first front panels. The other thing that we need to consider is the style of headlights for the car. I’ve got a few ideas.
Work on the outrageous rear wing is also coming along, here’s the latest mock up. An off the shelf black aluminium wing can be seen positioned on the rear deck of the car, this is being used for styling cues and as a guide for mounting mechanisms for our wing. Of note, the black wing is about 160cm wide, giving some perspective as to just how wide the Ligero prototype is! The other two rectangular foam structures on the rear deck are the plugs for the rear snorkel air outlets.
Thanks for looking, dan.
