Murray T25: that revolutionary 'door' explained

Steve Cropley
Now that the wraps have come Gordon Murray’s revolutionary T25 city car (we scooped it undergoing road trials today) I thought the great man might not mind if I cold-called at his Guildford design HQ, south-west of London, seeking a few more details.

Reception for the car’s shape and concept has been both strong and positive, many people using the word “funky” for the cute and revolutionary styling. However, what nobody understood - because our hastily-snatched picture failed to explain it - was exactly how the T25’s one-piece door worked. If I asked nicely, would Gordon show me?

See Autocar's exclusive Gordon Murray T25 pictures, including the radical 'door' in operation

The answer was yes. I was smuggled into the workshops (where several other fascinating projects were shrouded by hack-proof dust-covers) and shown, in the flesh, the same T25 prototype our cameraman had seen.

First impressions: it’s tiny, but its stance, height and the clever resolution of its distinctive styling give it an impressive presence. That’s good. The last thing you want is for your tiny car to seem toy-like, and the T25 doesn’t.

The door is a typical example of Murray being brilliantly simple, other examples of which are visible all over the car. A large, rigid assembly comprising the windscreen, the side windows and side panels and much of the roof, all swings forward with BMW-like precision to present a low-sided cockpit into which all three occupants can step into with ease and convenience.

The cabin cover - it’s not enough to call it a door - is gas strut powered. You open it by pressing a button on your keyfob remote as you approach the car. When the car is tightly parked against others, access is far more dignified than for any conventional car. Closing the cockpit cover is easy: it’s part-supported by gas struts, but gravity helps you pull it down until it’s nearly closed, when a soft-closing mechanism takes over and pulls it securely against rubber seals.

Sitting for the first time in the T25’s central driving seat, two things struck me. First was the unique appeal of a symmetrical vehicle, which only the motorcyclist - or the driver of a McLaren F1 or single-seat racing car - has been able to know until now.

Second was a feeling of value: it was hard to believe that the target price of this car is below £7000. The unique cockpit (into which Murray admits he has tried to introduce echoes of the McLaren F1!), plus equipment like the paddle-shifts, the push-button transmission controls, the unique instrumentation and the soft-closing electric door, combine to give the car a special distinction.

As I said when trying the bodyless ‘mule’ last year, this is a car people will want for many more reasons than its main event, the economy of build and operation.

We are looking at a motoring phenomenon that could eventually have the impact of Issigonis’s original Mini, 51 years ago.

I think this car looks great and if the price is right why wouldn't you want one for commuting within an urban area ? I do think that Murray maybe needs to try and get this to market earlier than indicated in your other article, in two years time there maybe many other small electric or petrol powered midgets, just look at your Changhai Motor Show report and pictures for evidence of that.

Could this car be sold in kit form to be built at home?

P1MUY April 26, 2010 5:08 PM

And when it's lashing down in the middle of winter....?????

TJ Hunter April 26, 2010 5:14 PM

It looks cool, and should be a great (and timely) addition to the worlds roads.

I presume the interior has been designed to allow for being opened in inclement weather; out of curiosity, how long does the opening process take Steve?

It's interesting that there are motors to open & 'soft-close' it too. Initially I would have said this addition wasn't very weight saving, but the removal of doors etc no doubt allows some leeway :)

Its performance in a crash would also be of huge interest. You have deformation on the central opening pivot to consider, egress in the event of being overturned (AMG SLS has exploding gullwing hinges for example).....

.... so lots of questions, and no doubt really elegant solutions in place. I'm really looking forward to how this story & car evolves.

Steve.

Great read,thank you,two years is far too long

to have to wait.

Any chance of a quick road test,any time soon?

every thing you say is right April 26, 2010 7:44 PM

Seven grand is a lot. I hope it's the right side of five. Really looking forward to hearing more about this. It's clear that there will be some convincing to be done concerning the less conventional features but I think this could be a winner.

I agree with Steve...

It does sound very promising, genuine fresh thinking in the city car segment. It could be Murray's biggest hit yet.

Leslie Brook April 26, 2010 9:58 PM

We had cars with doors like that when I was little. They were called bubble cars...

chandrew April 26, 2010 10:30 PM

I'm with P1MUY on this.  I just don't see how you could strap in small children and get in yourself in a downpour without finding yourself sitting in a puddle.

noluddite April 26, 2010 10:32 PM

That's a lot of surfaces to seal. Looks expensive. And the benefits are?

Old Toad April 27, 2010 7:31 AM

I reserve full judgement till I see exactly how the door cantilevers ? open.

However my initial thoughts are as some above what happens when its pouring with rain or in a blizzard. Will it be like the site dumpers I drove 30 years ago where you covered the seat with a Morrisons shopping bag to whip away just before you sit down to prevent getting a wet arse ?

Form over function maybe ?

beckstar April 27, 2010 9:47 AM

Great idea! However I agree with chandrew on this, have they dropped a huge clanger with the door design?

NobbyUK April 27, 2010 9:54 AM

A simple bathroom roller blind which deploys when the 'door' opens would protect occupants from the elements for long enough to hop in and out (have that one on me, Gordon) but that's just a small detail - I'm fascinated to see how the rest of the car works, especially at that image price; it's one thing to build a money-no-object, gold-leaf-engine-bayed masterpiece that the McLaren F1 was, quite another to turn out a higher volume 3-seater for under £10k.

RobotBoogie April 27, 2010 12:07 PM

Yep, I think the door will be a deal breaker for a lot of people. Just can't see how it is supposed to be practical in our climate.

RacingPuma April 27, 2010 1:30 PM

I do like the solution to the access problem - getting into the central position of a 3 seater isn't as easy as many people think.

Of course, it has been done before in a 2 seater - the Bond Bug.

One question remains, Steve.  Given the exclusive access you & Autocar have had to the Murray T25 project, how do you explain what you wrote last September -

"To get around the potential access problem, the T25 has two doors: a hatch at the rear and a side-hinged door at the front of the car that allows entry to the passenger compartment in the style of the Isetta bubble car. "

www.autocar.co.uk/.../242828

This was obviously unworkable as the front crash structure would impede access.  Could it be that you were doing Prof Murray a favour by throwing readers off the scent of more reasoned speculation such as this from 13 months ago

" Re: Gordon Murray T25

Don't laugh, but having studied all the teaser pictures and the full patent document, I have a sneaking suspicion that the entire windscreen, door and front half of the roof lift forward  in one piece, a bit like a Bond Bug."

Just horendous

bangertastic April 27, 2010 4:05 PM

Let's not be too harsh on the T25.

If you smear vaseline over your eyes and stand a long way away it looks a little bit like the McLaren F1.

beckstar April 27, 2010 4:23 PM

The issue over the door and the weather will not be a small issue with the buying public!

fuzzybear April 27, 2010 8:36 PM

Im still not convinced by elements of this, but I like to see a UK company, employing UK talent, thinking out solutions in a lateral way. If the Chinese can start an automotive industry from scratch, why can't we do that again. Since banks get bailed out like overindulged children, maybe a a subsidiary of McLaren, with all its expertise could be sponsered or conjoin with a Bank.

Am a Murray fan (despite his dislike of 2CVs) but also have concerns about the access arrangements. Rain and snow are unpleasant, but an inconvenience: what about blustery gale force winds - surely this solution generates a large, and potentially dangerous, wind load; and saying it's a city car isn't enough, I know of many 'rural' Smarts.

The other situation is in a emergency / RTC: even if we assume it doesn't deform in the crash itself, with the small window opening area there will be situations where access to occupants will be more difficult than a conventional solution.

On a more superficial note, you mention the opening and closing is electrically assisted - but don't indicate how quick it is and my guess it that it will take longer than a conventional door. I'm sure it'll be a novelty at first but it could get old, very quickly. Overall, this is clearly better thought out than the Peugeot 1007, but there are definite parallels with both that and the original A-Class - which were a little too clever for their own good and suffered commercially as a consequence.

sierra April 28, 2010 8:24 AM

I think Murray's shirt gives a clue to it's natural habitat - i.e., not countries where it rains.

Still look where the maker of Isetta bubble cars is today.

Peter Cavellini April 28, 2010 2:27 PM

I'm sorry, respected as Gordon Murray is i don't think people are going to want to be seen driving something that looks like this, it's anonimous, where's the Murray flair?, i can just imagine rows upons rows of these little boxes in cities, have we really given up on style?.

Pix26 April 29, 2010 1:49 PM

Rather than worry about how the door/roof will perform in an accident (there's legislation to cover that type of thing), how do you get out when its been rolled onto its side at a roundabout?  Waiting to be rolled upright could be even more embarrassing than actually being seen driving it!

Casanova April 29, 2010 1:55 PM

Anonymous? It's hardly like every other car on the road, is it?!

Peter Cavellini April 29, 2010 2:24 PM

How about Orwellian then, where everybody drives the same type of car in the same spec?.As for accidents and getting out the ONE door, maybe it's like the SLS and have explosive bolts too "blow the bl--dy door off!!!"
