Called the T.33 Spider, this is the fourth model released by Gordon Murray Automotive (GMA) based in Surrey.

It is the brand spearheaded by – and named after – the automotive genius behind Brabham and McLaren F1 cars of the past as well as the legendary McLaren F1 road car.

It will cost from around £1.9million before taxes, has a pair of hidden storage compartments and should be able to top 200mph flat out – and only 100 will be made.

As with its other road-going cars, production will be strictly limited to 100 examples and it will be built by hand.

This is to ‘ensure exclusivity and offer a highly personalised customer experience’.

It is being made at GMA’s new global headquarters and technology campus in Highams Park in Windlesham, Surrey.

While the price tag hasn’t been officially confirmed, it is expected to ring in at around £500,000 more than the £1.37million coupe model (before local taxes) it is based on – which is already sold out.

That means the total cost for a British customer – inclusive of VAT – will be around £2.25million.

GMA has revealed that around half of this latest topless car already have deposits, meaning potential suitors might want to dust off their chequebooks sharpish if they want to secure one.

That might sounds like a substantial premium for a pair of removable carbon-fibre ‘Targa’ roof panels, but the Spider has been fully reworked.

The design from the A-pillar (the windscreen pillars) backwards is completely new.

It will use a mid-mounted 3.9-litre, naturally-aspirated Cosworth-developed V12 engine with a maximum power output of 609bhp and 451Nm of torque linked to a six-speed manual gearbox.

It makes three quarters of its full power at low revs of just 2,500rpm, which should make it a usable – if not very expensive – supercar.

The car as a whole weighs just 1,108kg, which is a mere 18kg more than the hardtop model and around the same as Toyota Aygo city car.

The engine itself tips the scale at just 178kg. That makes this the lightest production V12 powerplant slotted into a road car.

Like the price, GMA has not disclosed the performance figures, but a top speed in excess of 200mph is very likely.

Unveiling the new motor on Tuesday evening, Professor Gordon Murray CBE said: ‘When drawing a car I imagine what it’s going to feel like to sit in, and how it will feel to drive.

‘So from the first sketch I knew that, with its open cockpit and the incredible Cosworth GMA.2 V12 engine right behind you, the T.33 Spider would deliver a truly involving driving experience that’s quite unlike anything else.

‘And while it’s still a mid-engine supercar I wouldn’t accept any compromise on usability: this is why the T.33 Spider is unique in the supercar sector in delivering both onboard roof storage and a 295 litre luggage capacity.’

And it’s the luggage compartments are definitely a worthy talking point of this car.

That’s because there are two hidden in the rear haunches of the T.33 Spider.

Push a button and – when the dihedral doors are open – a pair of 90-litre compartments pop open.

‘The mechanisms through which these doors and stowage compartments open are works of engineering art and design ingenuity – their seamless operation being vital to ensure that T.33 Spider is a truly usable supercar,’ the Surrey brand says.

It also has a small amount of luggage space (180 litres) under the bonnet to provide baggage space on par with a Vauxhall Corsa. The front boot will fit the pair of removable roof panels if you want to go with the top down mid journey – but there is no roof for anything else if you make that decision.

Inside, Murray wants this to be a supercar that sticks to business. That’s why it has a simple – not distractingly busy – cabin with a central rev-counter in the instrument cluster.

There are two separate displays – one to control the infotainment with Apple CarPlay and Android Auto capability, and one for the climate controls.

Racing-style seats and skinny – uncluttered – steering wheel are made from carbon fibre but wrapped in leather for better comfort, as well as a few dashings of Alcantara for that sports car feel.

Production will likely begin from the middle of 2025 and start once the 100-model coupe run has been completed.
