I disagree. It seems to me that a tricycle is a special case of three-wheeler. It would be absurd to have an article on tricycles discussing Bubble cars and Reliant Robins. — Theo (Talk) 19:35, 24 August 2005 (UTC)
Merge, this time, with Three_wheeled_cars. The contents are quite complementary. I'll let anyone tell which title is better.
I should say that some content from the tricycle article should partially be merged too. What do you think ?
The domain could also be clearly organized with articles like -

How about this:
Reasonable idea?
Respectfully, SamBlob 22:15, 9 March 2007 (UTC)
A Three Wheel Car and a Reverse Trike as I like to call them are completely different monsters. I think more should be elaborated on the physics and handling characteristics of each that way readers have a better picture then "It’s just a backwards three wheeler"

A merge was apparently originally proposed here in 2006. I recently re-tagged tilting three-wheeler and three-wheeled car to be merged here. Andy Dingley ( talk · contribs) de-tagged the former and then undid a subsequent redirect, leaving a note here on the old merge discussion which I've now moved below:
* Oppose This is no better an idea for a merge today than it was back in 2005 Andy Dingley ( talk) 16:00, 27 January 2012 (UTC)
The thing is, I've already done the work. Tilting three-wheeler is now redundant to the material contained at three-wheeler#Tilting option. Unless there is some disagreement to how that work has been done (personally I think I've done an adequate job of the merge), the redirect should be put back in place. If, at some later point, the tilting aspect requires an article to be spun back out again then so be it, but for the time being there is too little referenced material to truly warrant a separate article for this aspect of the subject.

So you mention all the configurations, cars with only three wheels, motorbikes with a extra wheel at the back, a bunch of comments that actual seem only to be relevant for recumbent (un-powered ) bicycles. What about a motorbike with a sidecar ? That used to be a very common form of three-wheeled motorised vehicle. Eregli bob ( talk) 00:12, 26 February 2012 (UTC)
Isetta looks like a three wheeler, but has four wheels (two aft wheels in a closed position). Plxdesi
I see this stated all the time, but where is there a reference in any literature that shows this to be true? In fact it is blatantly false if the vehicle is properly designed. There is only one research paper that addresses lateral stability for three wheel vehicles and it is based, not on supposition, but on actual testing. It was published in 1981. In it the researchers did an exhaustive literature search of over a million documents trying to find any references to stability issues and testing that would confirm this statement. They found none. The research report can be found under the following title: Evaluation of Electric and Hybrid 3-Wheeled Vehicles for Handling and Stability DOT HS-806092; September 1981, authors Paul G, Van Valkenburgh, Klein, R., Szostak, H.; Contract No. DOT HS-9-02309. Volume 1 is the Executive Summary and Volume 2 is the Research Report. It is not available online. It has to be purchased in a print format. The research report is more than 130 pages. Quoting from the Executive Summary Conclusions, "There are small differences between 3- and 4-wheelers. The original question leading to this research was: “Is there any performance difference between 3-wheel and 4-wheel cars?” Within the limits of the capabilities of the vehicles tested, few differences were found that could not be explained by factors other than the number of wheels. For example, if we look at the vehicle factors that affect handling, stability, and braking, we can see that there are only a few that are functions of the difference between three and four wheels. This research shows that traditional state-of-the-art vehicle dynamics knowledge applies to 3-wheelers also. The handling characteristics are still primarily a function of suspension geometry, weight distribution, steering and suspension compliance, tire properties, etc. The only obvious exception is that anti-roll bars are of lesser significance because the front/rear roll rate distribution is not a variable." "Single rear wheel configurations understeer...Single front wheel configurations oversteer. ..Oversteer is difficult to control. ..Overturn is easily avoided. While for a given track width and center of gravity location a 3-wheeler will overturn more easily than a 4-wheeler, these variables are easily modified so that a 3-wheeler is superior. In fact, one 3-wheeler tested had a better overturn safety margin than most 4-wheelers,...Based on the research done to date we believe that it is possible to build a 3-wheeled car with essentially the same handling and overturn characteristics as any given 4-wheeled car." Johpav ( talk) 07:29, 16 April 2013 (UTC)
"Diagram showing an initial velocity vector for three vehicles and the corresponding angular displacement from the initial wheel positions required to change the direction of the initial velocity vector by the same value when turning using various three-wheeled car steering mechanism configurations"
This is a joke, right? This is meant to be funny? God, I hope so. — Preceding unsigned comment added by Paul Murray ( talk • contribs) 11:01, 23 May 2014 (UTC)
"Which way you must turn the wheel in order to steer in the direction you want the car to go" is my educated guess. The diagram might be useful if anybody could understand what the text means! Walshie79 ( talk) 02:22, 11 September 2020 (UTC)
I suggest to merge Tilting three-wheeler into this article. I removed the previous merge tag a few months ago simply because the discussion was old, I hadn't looked very thoroughly into the article then.
There are at least one reliable source listed at the bottom of the article i think, does anyone have that on hand? The link only points to a summary [1].
If not, and if no other sources can be found, I would guess that it's kindof difficult to fix the huge problems the Tilting three-wheeler article has. I can't see any other way of fixing it other than just removing everything, leaving us with very little, and that can be in this article.
