The Pixel Concept Car

08/10/2011 12:07 PM

i have just bought a Tata Nano car... something i always wanted to do, as a salute to the engineers who created something nice that people other than India.com can be proud of.

The other day, i got this (from a mailer from Globalspec !) wonderful tidbit....awesome for me. Maybe old hat for most of you...(Pixel is based on the Nano platform)

http://www.youtube.com/watch?v=Pk_S7t31VDY

The rear-wheel drive Tata Pixel concept mini-car uses a prototype toroidal traction drive infinitely variable transmission. Bottom line: one rear wheel can be driven opposite the other rear wheel. With the front wheels at an extreme angle, watch the 3 m long car turn with a 2.5 m radius for parking in tight city spaces.

Views please? (The TATA group is perhaps the most respected in India, and perhaps deserves that position in the world too. Their integrity is almost unbelievable in today's situation. They will welcome critical opinions with humility and do their best to address them)

i have never been involved with any Tata company as an employee or a beneficiary. i am one of their admirers, thats all

Very neat!

My one concern would be, with the zero turn, if a person was to over steer at full speed, it would probably turn into a little rolling ball. Is there something built in to prevent that from happening?

i could go for double wheeled axles or 6 wheels ,or how about smart wheels that pop out of the sides a little while making a turn.

While its still in the planning stage why not design it for ATV ON Road clearance.ds

The pixel is a very impressive car. It's crash worthiness and airbag layout is very fine indeed. I don't like having to stare at an iPad-like device to control all of my cars other functions, though. Big, easy to see and handle controls don't require having to take my eyes off of the road. I can find them in the dark.

I would assume that like the four-wheel steering vehicles already in the states and elsewhere that the extreme steering angles would be modulated by the speed of the vehicle.

Thank you for your kind words friends. This car is unlikely to be ok'd by the US users i am afraid. It is too small !

It is more likely to be acceptable to the Europeans.

Nevertheless, a neat concept....

I have been waiting for a car that falls into my low price range. Tata seems to make cars that do it well. Small size is quite a strict requirement for a car that I would consider purchasing, and that makes me unusual for someone in the US. So, I'd really like to have them here in large numbers!

If this becomes marketed in the U.S. (or legally importable), I would be interested. Very cute, and I don't need to drive far or fast on this island. Either engine or electric would work for me.

The Pixel, among other concepts from Tata, is why Tata is very soon going to be leading the automotive industry world-wide, while the old dinosaurs of the US and Europe continue to seek handouts from their governments, until they roll over and die.

Remember when the original VW bug invaded the US? Pretty small for its day, and no US company would believe that such a small car would ever find a market...

The US government's blocking of the Tata has nothing whatsoever to do with safety. It is an attempt to protect a dying US industry from "unfair" competition...

While i am patriotically proud of the House of Tatas (The >100 year-old Indian Institute of Science is a temple of learning, thanks to the vision of JN Tata), it is very heartening to hear such good words from experts like you and others. Thank you.

yes KVS. II-Sc is the jewel institute.

To innumerate Tata's vision, we need to make a big list...

IISc, TIFR, TISS, many dams around Mumbai....

Regarding car, I opine little different. True the car is very nice, very low cost.

But low cost itself is a problem. Now a days motor cycle is costing Rs 50000 and this car is costing around Rs 130000/- Motor cycle occupies very small area. Car occupies much more. So surely it is going to create great traffic jam problems in cities like Bangalore, Pune. Already the traffic problems are severe in Bangalore and Pune, they are going to worsen.

About the Nano, some clarifications:

1. i paid Rs 221,000 for the CX model with AC. Even the base model is ~ 180000.

2. i wish i could use a scooter, but at my age, and the two-wheel traffic being what it is, i have to have a car.

3. The statistics at least in Bangalore show two or three younsters dying in tragic two-wheeler accidents daily. Would not happen if they were in a car.

Moreover, its inner space, amazingly, is bigger than a Santro or WagonR. This was my prime concern, since my wife cannot bend her knee, so can't get into a low car (i tried out all the Hondas, Toyotas, Suzukis and the Fords... all very good, but impossible for my wife to get into except the Hyundais and the WagonR)

Anyhow, my post was about the technology of the Pixel, with its maneuverability in small city spaces made possible by the reverse drive of the rear wheel....

Forklifts do this, too; the rear steering wheels can turn through 180° or slightly more, with the front drive wheels turning in opposite directions. That's one thing that caught my attention to the Pixel.

Of course, never occurred to me. i am sure many earthmoving and specialised machines have this kind of drive. Hadn't seen one in car though....are there any on the road somewhere?

Ford and Chevy used this on trucks a few years back. I think it's still available as an option.

But...it was not used as effectively. The wheelbase on those vehicles is much larger in both aspects.

KVS

Your personal needs can be perfectly understandable.

The accidents are because of some different reasons. Why it is mainly of youngsters? The careless driving and breaking the basic rules of traffic are the real reasons.

True with cars the accident deaths will reduce (partially because if many more cars on road, the speed of traffic itself will be drastically lower down). But still the problems due to many more cars on road will make traffic very slow.

I agree your post was for technology. In that sense, I accept my posts are Offtopic.

Please keep us updated about your experiences with the Nano (maybe in another thread).

Well, if our country is in such a dire situation you don't need our pitiful dollars then, do you? Yeah, didn't think so. If you want to be stuck up about it, then keep your cool little car...we'll but similar ones from Germany and Japan in a few years anyway. I am sure they will want to sell to us.

Don't be hatin'

Cuba Pete-

As an aside, I was born, raised and educated in the US, and started life as an avid patriot, giving seven years of my life to military service in support of the American Dream (following in the foot steps of my ancestors- our family has served in every US war from the Spanish American to Vietnam), even volunteering to serve in a most unpopular war.

I realized what a "dire situation" the country was in back in the early 1990's, and did something about it...

The Nano and Pixel are amazing achievements, but Tata is also famous for destroying prime agricultural land without even compensating the farmers. I would thus assume that they cut every other corner possible, rather like Wal-Mart.

I think information available with you is not correct. TATAs paid for the land acquired by them.But it was political issue and they were targeted, they had invested around Rs.1400,00,000/ in the plant which they were forced to shift to other location in Gujarat western India.
