electric motors produces peak or majority of it's torque from the start and is able to maintain it through it's rev range...  this means you get to move off from standstill say a traffic light or pulling out of a corner fairly easy with the electric motor assistance... it provides torque to launch the car forwards where the petrol engine is lacking during move off...

i don't think our insights or hybrids are capable of that sort of power outputs whether they can hold it through the entire rev range or not...

electric motors don't have flat torque, if it peaks from the start then it doesnt peak at end right? so how can it be flat?

did you study engineering before? hmm.gif

OK, they have flat('ish) torque... with load, electric motors will generate an almost fixed amount of torque depending on the current being fed into it ... so, it depends if the manufacturer will vary the current being fed into the motor to control the power output...

flatish torque.. lol.. ? DC electric motors have decreasing torque curve, and certainly not flat.. as i ask before you got study engineering wan or not? hmm.gif

and as for current jap hybrids, they even have very unique characteristics..
IMA: ultra-thin, permanent magnet, three-phase synchronous electric motor/generator

haha, oh my u never seen before hybrid cars above 2L in malaysia? and because of that you call me idiot? simply call people idiot?

precisely because of the tax it's expensive, but yeah... there are some running around malaysia.. u want to see photo or not?

ok you make your point for existence of hybrid with above 2.0l in msia... you have my apologize for missing the word CC in your statement..

but what is the selling price before tax of 30% + 75%? (there is always sales tax of 10%)
*
ok peace.. icon_rolleyes.gif

some industry comments and prices if those taxes were removed.. in this link.

just test drive preve n booked one today. in my opinion, if the car is well taken care of, then is no problem. the only thing i feel not good is the initial torque is very slow one unlike the honda i drive. overall its a decent car. too bad cannot change the interrior to leather seat or what ever

good luck in your jewelry sales.. after that can deposit to buy car liao.. thumbup.gif

you see the torque decreasing due to the increasing output speed (this is exactly what your article says)... same applies to an internal combustion motor... as you increase output speed, the torque will also decrease assuming a simillar amount input is fed to the motor through out the range...

"The graph above shows a torque/speed curve of a typical D.C. motor. Note that torque is inversely proportioal to the speed of the output shaft. In other words, there is a tradeoff between how much torque a motor delivers, and how fast the output shaft spins. Motor characteristics are frequently given as two points on this graph:"

my point previously was that and i admitted for using the wrong word that electrical motors have a more linear torque curve compared to a petrol motor... and as long as a load exists, and constant power is sent to the motor, it should provide same torque rating throughout... it is back to how they vary the current fed to the electric motor to adjust the torque output....

this has nothing to do with engineering studies.. it is general knowledge as this are things you come in contact with in daily life...

nope. you can see the stall torque is higher at lower rpm and decreasing with high rpm.. so it's not constant torque throughout the rpm range. constant torque means flat line, as you can see the line is decreasing downwards..
