A client design commission for interior and exterior updates to a 1972 Porsche 911 Targa that was designed and developed in 3D and put through a full CFD study.
We started by adding the wider arches from the later model and smoothed and slightly deepened the front spoiler, adding chrome slats to the lower inlets to match the upper vents. Modern headlamp units were also specified and the later bumpers were chromed to keep the original classic look but with body coloured inserts added.
Our client wanted a restyled roll hoop and liked the 918 style at the rear and a faux intake was requested. After different configurations we actually developed a working air intake for the engine that feeds through the roll hoop and down the inside of the rear window in to the engine bay.
The restyling of the roof panel also allowed us the gain some additional headroom and a nice curvature to the roof, as the original is a little flat in side profile.
With the design and development carried out in 3D, it gives us the ability to try different configurations and material finishes such as this copper coloured trim version to replace the chrome on the car. Although quite striking, it was decided to keep to the classic chrome finish for the final car.
The interior was given a full restyle with different material options tested. The original dashboard layout was retained but new door cards and steering wheel was added along with updated and restyled instruments.
New seats were styled and trimmed in a leather combination that the client preferred with exposed white stitching to match the contrasting side bolsters. Note, the new air intakes built in to the roof panel feeding the engine via the pipework inside the rear screen.
The complete car was put through a new CFD (Computational Fluid Dynamics) study, that we can now offer as a service, where primarily the efficiency of the new roof air intake was checked. This data also gave us some interesting information and potential areas on the bodywork that could be altered to improve aerodynamic performance without impacting the classic Porsche shape with modern aero devices.
