Three wheeler Cabin Scooter Design

You could update it with a Suzuki Burgman scooter engine and with a slightly revised design, it could still have appeal...

Agree the Suzuki Burgman is a good update, some have been fitted with much larger engine.

Still no comment as to size... But 192 inches is 16 foot, wheelbase 120 inches is 10 foot... or ideas as to why so big.



It is only when seen with a person stand by one that you see how big they are. Any update would need to be smaller to be drive on UK roads.

There are a couple of items on You tube about these. Below are links to two of them..

A few second of first uncovers a problem, the engine is loud! Could you put up with that for any length of time, needs sound blocking between cabin and engine. The second show the size very well.

The Acabion GTBO a claim top speed of 300mph! Along with a million pound price tag. Surprised this not had post this before. Do any of you believe that top speed or the sub 3 second to 100mph?

I want one on Top Gear! Could we do a kit car like this?

Is it really just a very silly car/motorbike?

Good post, Short, informative and answered the questions. And 100$ correct.

The above is the Phantom R from Unknown Choppers. I agree it is not a cabin scooter, but is cool looking.I wonder what it's like to drive/ride.

That is even more questionable than the previous one .Show vehicle only I would think ?

Yes! It still looks cool!

I did say not a scooter design. To me it looks like a render, a very good one, but a render.

more like hoRENDERous in my op

Good post and I trust you are well. I am still immersed with too many vehicles and insufficient time and energy to finish most of them. However I am determined to get another three wheeler Berkeley on the road and negotiating currently. Just bought an MGF which will be OTR by late April and with a heavily reworked high output K series fully rebuilt engine in the rear it should keep my summer motoring in the breeze going I hope!

These tilting three wheeler's raise a lot of questions IMO and offer few answers. I am convinced that a layout of a three wheeler like the Berkeley fitted out with modern mechanics (NOT the A series!! fat too heavy) such as a high output motorcycle engine would still more than hold its own against any other modern three wheeler. But no doubt some will say that I an biased towards Berkeleys. I am I love them!

Anyway I do appreciate the post and look forward to the replies.

I think this one is great but it is interesting to note that the front wheels do not steer, when they park near the end of the clip it appears that the back wheel skid steers.
Maybe it has rear wheel steering!

The trouble with rear wheel steering is tight manoeuvres such as parallel parking You have to get your head round it. It can also be very tricky at speed. Trust me I've done quite a bit of rear wheel steering though it can also be highly manoeuvrable too Look at fork lifts.

Interesting to see what might come of the Toyota but it's currently just a concept and CGI

Several sources subsequent to the Geneva launch are quoting that the project has 'moved beyond the prototype stage into field trials'.

Toyota's own press release has this to say about the suspension/steering:

Toyota said:

Key to the higher levels of stability, safety, comfort and enjoyment associated with the TOYOTA i-ROAD driving experience is Toyota's new, entirely intuitive 'Active Lean' technology.

The system features a lean actuator motor and gearing mounted above the front suspension member, linked via a yoke to the right and left front wheels. An ECU calculates the required lean based on steering angle, gyro-sensor and vehicle speed information. And the system automatically moves the wheels up and down in opposite directions, applying lean angle to counteract the centrifugal force of cornering.

Offering a minimum turning circle of just 3.0 metres, the system also operates when the Toyota PMV is being driven straight ahead on a stepped surface, the lean actuator automatically compensating for changes in the road surface to keep the body level.

No mention of rear wheel steer, but if there are two (hub?) motors, one on each front wheel, there's no need for a chain/shaft drive/swing arm at the rear to prevent steering, and you can do pretty much what you want with an active steering/suspension if you get the sensors and programming right.

Question is, do we trust a company to get such a system right when the same company very publicly failed to get a drive-by-wire throttle pedal and ABS braking software to work right? I wonder if they've given the test drivers 'rising sun' hachimakis?

Nice to see you back Steffan and hope things are well with you.

Tilting cabin threewheelers will become an interesting vehicle in future Urban environments...maybe, but just for fun and inexpensive motoring, nothing beats your Berkeley T60.

Maybe in todays roads, a modern 3cylinder car engine, something like a Toyota Yaris or Daewoo Matiz engine, might make for a perfect donor update for such a classic.

Just an idea...

I had a C1 - same engine and an absolute cracker. Can be turbo'd now as well!! http://www.c1gti.co.uk/

I do appreciate your felicitations, fuoriserie! My recovery has been very good and I am pretty well back to full health. Certainly going to get a few projects finished this year!

I personally very much doubt that these tilting three wheeler's raise anything other than a great many questions. I have examined a number of the concept vehicles and design exercises in this form over the years and I have never seen any such vehicle that I would feel safe in on busy roads. Possibly as a city vehicle, but I remain distinctly unconvinced that there is a mainstream future for them.

To my mind the two wheels at the front as demonstrated by Morgan, BSA, Berkeley (hurrah!!), and the more modern types like the Lomax, the Blackjack, the Pembleton the AJS, MEVTR1, Grinnall Scorpion, Triking, Buckland, Japster and Aero Merlin and so on underline the inherent safety in that design. I would (and still do) happily drift around corners on three wheels on an appropriate circuit in any of these types of car. The inherent stability appeals to my sense of self preservation. The tilting designs cause me serious concern on the road,

But you are the car designer. I am merely a retired accountant who has avidly experimented, built, collected driven and enjoyed every aspect of kit cars for some 50 years this year. I really want to see the Kit Car business as it was in its heyday when Dutton, Caterham, Chesil Robin Hood, Locost, Moss, Burlington, NG, and all the other old kit cars were really producing a fair number of kit cars. Anything we can do in the economically challenged UK to achieve that will get my vote! What are you planning Fuoriserie we need to know!

Well, I've been working on a few lowcost designs for quite awhile and a few will be coming to fruition soon, but can't say more at the moment.... you have a PM.

I would agree Qdos, rear steer can be sensitive. Toyota seem to have solved the issue however
