I have an idea for a new kind of hybrid car that uses the same parts but eliminates low gears (first and second shifts) in any transmissions found in today’s hybrid cars. I noticed that hybrid cars still use first and second gears, something which no longer makes any sense to me because there is already an electric motor/generator commonly found in hybrid cars today. In the video, I explain how my changes to the hybrid car’s transmission would work and how this would impact the environment. Sign language is featured by the narrator in this video with subtitles throughout.

The guy needs to do some homework on hybrids.
I drive a Prius and studied up on it before I bought it.
The gas engine does not run until the car reaches
about 20mph unless you are going up a hill or want
to accelerate quickly. The car runs on gas or battery
or a combination of the two depending on load.
The Prius has only what might be considered 3rd gear.
The engine is set up to run at higher speeds and
in combination with the electric motor provides a very
economical vehicle. I can easily get between 48 and 52mpg.

Ira, I just did my homework on Prius at Wikipedia a few mins ago.. well, my concept is not exaclty similar . Ira, Prius runs entirely on MG2 (motor generator #2) from stop to top speed while mine switch between electric motor and gas engine propulsion at around 20 mph. Priuses has no gear ratios whatsoever but uses CVT transmissions which technically has first and second gear equivalents . I am glad that you forced me to do my homework, though. I cannot say that my idea is better or worse than Prius’s. I just feel that Priuses carry too much baggage, in my opinion.. My only question is whether my idea will deliver better fuel mileage or not. I dont know really.

Ira, even if my concept cannot beat Prius, I am sure that my concept can be applied to those far less efficient models that people still craves but also wish to see much improved fuel mileage without too great a sacrifice in performance. . I believe that my concept can help boost fuel efficiency much better than anything on the table so far. Prius is a great efficient car but not everybody will want it, right? this is where I try to fill in.. to help contribute to improved fleet efficiency overall. I wouldnt be surprised to find that my concept can really boost bigger models like pickups or vans or SUVs fuel efficiency a great deal with a motor generator that function primarily as first and second gear . Electric motors deliver linear torque best at low speeds without any slip at all. You can compare it to an heavy duty electric drill or grinder that keep going without being stalled at all. At higher speeds, i doubt that electric motors can be efficient due to disadvantages of electromagnetism at higher rpms, I suspect. Again , I havent done my homework on electromagnetism!

Sorry but the heavier a vehicle is, the more it needs gears for starting up a hill, the controlling spec on most vehicles.
Most hybrid E motors are not big enough for starting without gears to help. The Prius has an infinite number of gears, not just 1.
I do drive, design and build EV’s every day and while almost no EV’s has more than i reduction gear, they also have far more power than hybrid E motors do which can always call upon the gas motor and gearing to help.

Also, I feel that the future of EVs will rest entirely on quadcycles or tricycles utilizing bicycle frame designs.. Attempts to mimic the traditional automotive manufacturing technologies will probably attains the lightweightness necessary to make successful EVs.. Moreover, the streets has to be revamped and lanes repainted to keep traditional automoitve dinosaurs apart from the rickshaw like EVs. You can point me to Tesla Motors , but I am not impressed with the skyhigh prices . I am looking for sub-$10K EVs that rolls on puncture proof bicycle tires, pretty much as is… If more people start to buy tricycles or quadcycles in droves, then the manufacturing costs will be scaled down thus allowing more amenties to be added all along . I dont think it is really necessary to go faster than 40 mph but the battery range is more imperative than the maximum speed . I would be more than happy to travel around America at 40 mph… if this will mean I cannot use the Eisenhower style highways at all. , as I would gladly take the back roads ..Motels or even campsites will spring up along the back roads like the old times!! Lets slow down.. for now.. Who knows… we will figure out how to pack more amphours in batteries in the future. An EV with 40 mile range at most is a dead on arrival !! I want hundreds of miles per charge if it means lower speed and lighter rickshaw like cars..
