You're probably right, Battar, but I like to have a more optimistic view and hope that by making these type of cars before there is demand for them, somehow the demand eventually will be created. I hope these cars will be so good that those people who still have 200k+ gas guzzling cars will eventually give them up and go EV or hybrid.
You have a good point j-allen. The main problem with gas engines is that they drain a lot of fuel in the city limits when the traffic is at its peak. Electric cars can help in this regard with their limited performance capabilities since nobody will be needing a superfast electric car when they're stuck in traffic and moving at a snail's pace.
Charles, a series-wound DC brush type motor would be a very good motor for a dragster because the torque is greatest at zero speed. The challenge there is that the current draw is greatest also. The other challenge is the range of speeds available with a given motor design. The big problem is that as the speed increases the back EMF also rises, which reduces the current, and thus the power. So to keep accellerating the supply voltage needs to keep increasing. Thus the need for gear shifting, unless the car finishes the quatrter mile befor the motor torque starts to fall off.
The motor type is described as "AC Synchronous", which is a type of motor that has a definite best operation spread of speeds. The DC series type of motor is quite different in it's speed-torque curve. So for most efficient operation different gear ratios will be quite beneficial. Study the curves and you will understand why that is.
Not sure I understand the need for a gearbox in an electric car, unless you need to "feel" like a combustion engine car... Or is it because they are using very small motors that could not sustain both high accelerations and top speeds ?
Some cars are more reliable than others, but even the vehicles at the bottom of this year’s Consumer Reports reliability survey are vastly better than those of 20 years ago in the key areas of powertrain and hardware, experts said this week.
As it does every year, Consumers Union recently surveyed its members on the reliability of their vehicles. This year, it collected data on approximately 1.1 million cars and trucks, categorizing the members’ likes and dislikes, not only of their vehicles, but of the vehicle sub-systems, as well.
A few weeks ago, Ford Motor Co. quietly announced that it was rolling out a new wrinkle to the powerful safety feature called stability control, adding even more lifesaving potential to a technology that has already been very successful.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
