Recognisable heritage. A new identity.
The starting point for the GT-100 is one of the great British sports-car shapes of the 1950s.
The Healey 100 has an extraordinary simplicity: a long bonnet, low scuttle, wheels pushed towards the corners and that wonderfully simple falling rear body line. We don’t want to redesign those proportions simply for the sake of being different.
But neither is the GT-100 intended to be a faithful reproduction of a car designed more than seventy years ago.
The challenge is to preserve the signals that make the shape instantly familiar while allowing the GT-100 to develop an identity of its own.
Giving the GT-100 its own face
The front of the car gives us perhaps the greatest opportunity to do that.
The original 100/4 has an extremely distinctive grille and two large headlights. Rather than simply reproducing them, we’re exploring a new treatment influenced by another strand of British sporting-car history — particularly the twin-headlamp Jaguars of the 1960s and 70s.
Four round lamps immediately change the expression of the car without requiring us to disturb the basic Healey proportions.
The grille then becomes perhaps the single strongest opportunity to establish a recognisable Teifi design signature.
Our current studies explore several different shapes. Some retain the broad, low proportions of the original 100/4 opening; others introduce a taller oval or a more Jaguar-influenced form.
The internal treatment can change too. Vertical chrome bars give the road car a distinctly period character, while a simple mesh grille gives exactly the same basic shape a much harder, more purposeful appearance.
The aim isn’t to reproduce either a Healey or a Jaguar grille.
It is to arrive at something that eventually becomes recognisable simply as Teifi.
Same shape. Different purpose.
One of the central ideas behind the GT-100 is that the same basic car should be capable of becoming a beautifully finished road car or a genuinely competitive motorsport car.
The exterior should reflect that.
A road-focused GT-100 could retain chrome vertical grille bars, small quarter bumpers, relatively restrained cooling apertures and the wonderfully clean surfaces that make the original shape so successful.
At the other end of the range, the higher-performance car can be much more assertive.
The chrome grille gives way to mesh. A front splitter manages airflow beneath the car. Brake and engine cooling ducts become visible. Additional bonnet and wing vents extract hot air, while the flat floor terminates in a functional rear diffuser.
A hardtop can further change the character of the car, both visually and aerodynamically.
These aren’t styling accessories added simply to make the competition car look faster. Wherever possible, the visual differences should exist because the engineering requires them.
That suggests a useful Teifi design rule:
If there’s a hole in the body, there should be a reason for it.
Aerodynamics without losing the shape
We aren’t trying to make a 1950s sports-car shape behave like a modern prototype.
Nor do we need to.
There are significant aerodynamic improvements available without destroying the character of the original design.
Much of the work can happen where it is barely visible. The GT-100 chassis gives us the opportunity to create a substantially cleaner underside, with the exhaust systems contained within the sill structures rather than hanging beneath the floor.
At the front, a subtle splitter can control the air entering beneath the car. Cooling air can be deliberately routed through the radiator, brakes and engine compartment and, just as importantly, given somewhere sensible to escape.
At the rear, careful management of the underbody flow and a functional diffuser offer further opportunities to improve stability at speed.
The objective isn’t maximum downforce.
It’s a car that remains visually faithful to its lightweight 1950s origins while benefiting from seventy years of accumulated understanding about how air moves around a car.
Weather protection from the beginning
A GT-100 should be a car that gets used.
That means proper weather protection cannot be something we attempt to add after the body has been designed.
The windscreen, doors, seals, hood and hardtop need to be considered together from the beginning.
The original Healey gives us two interesting starting points. The soft top creates a relatively simple roof profile, while the traditional hardtop gives the car an entirely different character.
For the GT-100 we’re exploring both, including the possibility of a more aerodynamically developed hardtop.
That doesn’t necessarily mean reproducing the original roof shape. A more vertical rear screen, extended rear quarters and a deliberately defined trailing edge could potentially provide cleaner airflow separation while creating another distinctive piece of Teifi design language.
Most importantly, both the soft top and hardtop should be things an owner actually wants to use rather than equipment tolerated only because it happens to be raining.
Evolution, not imitation
The intention isn’t to disguise where the GT-100 came from.
It should still make you think Healey the instant you see its silhouette.
Look closer, however, and the details begin telling another story.
The four-headlamp face carries a hint of classic Jaguar. The grille establishes a new identity. The cooling apertures have genuine functions. The splitter, flat floor and diffuser reflect modern aerodynamic thinking. The hardtop is designed as part of the car rather than added afterwards.
Underneath all of that remains the simple shape that inspired the project in the first place.
The GT-100 isn’t intended to recreate a car from 1953.
It’s an exploration of what that idea might have become if development had never stopped.
Recognisable heritage. Modern engineering. A Teifi identity of its own.
Evolution, not imitation.
