Needs? No. Wants? Maybe. We will see what the market is for the Porsche. I expect it to sell well to folks that can afford it. Porsche has no problem selling their current crop of vehicles.
True enough. The world actually needs a modern version of the āpeopleās carā. Tata created one for the Indian market, and now theyāve been expanding (albeit in short steps) into more lucrative markets through acquisitions. Iād like to see them focus on a basic, no-frills, compact economy car that people of limited means could actually buy for basic transportation. The problems is meeting modern regulations. I find myself wondering of perhaps there should be a category for cars for local use. Perhaps they could have different colored license plates and be prohibited from highways. Vehicles like this Daihatsu could serve a valuable function.
Actually, Iāve heard those no-frills econobox cars are no longer selling that well in India
Apparently, many people are now earning a better wage, and accordingly want nicer cars
I had a Daihatsu as a rental car once. It was a rattletrap. The cost was low, and I might rent another one if Iām in an area where I canāt drive fast. Iām not at all interested in buying one if Toyota decides to export them to the USA. Daihatsu is a good example of you get what you pay for.
If the flywheel bearings are big enough to withstand the reaction forces of a flywheel changing its spin orientation and the frame they they are mounted on is also, reorienting the spin axis will have the gyroscopic reactions of the two flywheels canceling each other.
The reaction torque of a flywheel being turned 180 degrees in a unit of time is EXACTLY THE SAME as the reaction torque of that same flywheel having its direction reversed by being braked to a stop and then accelerated back to full speed in the opposite direction in that same unit of time.
Or another possibility is just using a single flywheel oriented so that the torque reaction to changing orientation acts to counter the normal sway caused by going around a corner.
I have great respect for Porsche vehicles, but in the U.S. the Macan compact crossover outsells the companyās only sedan by almost ten to one now. The larger Cayenne also outsells all of the Porsche cars combined. Porscheās sedan sales are under 300 units per month in the U.S. and still declining. Cadillacās big sedans are also in steep decline. The premium automakers should know better than to keep pushing expensive, high-performance four-door cars. The market has turned its attention to crossovers, and compact and mid-size are what sell best.
I test drive a 2016 Cadillac CT6 about 2 months ago itās a very nice sedan, and attractively priced. Itās on my short list when I decide to buy a new car.
Yup!
Business Week had an article on that very subject several months ago, and now from within India come rumors that Tata will shut-down the production of the very slow-selling Nano model:
I guess that it would be fair to say that not enough guys in India found those Tatas to beā¦bodacious!
I seem to recall reading somewhere that the Nano was simply too small for the average Indian family. I have no idea if thatās accurate or not.
That actually makes some sense, butāon the other handāIndian families consisting of two adults and 2 or 3 children can frequently be seen riding on a motorbike. However, that does present one more possible reason for its poor sales figures.
The ātraditionalā favorite car in India, the Hindustan Ambassador, is actually a '50s-vintage Morris Oxford sedan that isnāt very roomy, but I suppose that it is roomier than a Tata Nano.
Oh, yeah, I LIKE that car!
ā¦yeah, but you wouldnāt like its driving dynamics.
In addition to atrocious handling and very poor acceleration, it has brakes that onlyā¦hint atā¦a reduction in speed.
LOL, Iām sure youāre right. Getting parts might be a problem too.
Re: the flywheels, it might help to remember that the energy contained in the flywheel(s) isnāt free. Some other power source has to get and keep them spinning. Then, when the car is parked, the energy contained in the flywheels is all lost as it spins down, converted to heat energy.
Well yea. The energy to charge an electric car isnāt free either. I donāt think flywheels will ever be an alternative to battery storage because of their limited energy storage capacity and like you mention, they eventually lose energy through friction. That can be minimized with low friction bearings and having the flywheel itself spin in a vacuum.
However, they may be perfectly suitable as a kinetic energy recovery braking system in urban vehicles. Let the carās kinetic energy become flywheel energy as the drive motors brake the vehicle and then return that energy to the car during the next acceleration.
It should dramatically improve the gas mileage of city buses and garbage trucks while minimizing brake wear at the same time. Iāve ridden city buses and it seems they are always either accelerating or braking, with some of the drivers accelerating until itās time to brake.
Ā© The driving operation of the vehicle is fed back to the driver by sounds. This helps realize a sense of oneness between the vehicle and the driver and thus enhances the āfun-to-driveā aspect.
VW did this years ago with out the silly artificially generated sounds with their Fahrvergnügen campaign.
Well, since flooring a Tesla is said to accelerate you into the future, maybe is should make TARDIS sound effects.
