Does KIA limit the total torque with this new model to prevent abnormal rumble noise while driving and at the end the drive unit must be replaced? Earlier model total torque is 291lb-ft. New model total torque is 188lb-ft.

Your guess is as good as anybody's....

It uses a smaller efficient motor from Vitesco with 6000 to 14600 rpm, so the torque is 255Nm at 5600rpm. The current model is 395Nm at 3600rpm.

Interesting info. Might we know where you got it from?

Pretty much all specified EV motor torque figures are virtually irrelevant. The reduction gearbox multiplies the available torque at the road wheels. Different reduction ratios on different cars have different torque multiplications.

It is the torque available at the wheels that really matters. A car with a lower torque motor can very easily have greater torque at the wheels (if the reduction gear ratio is sufficiently greater). Unfortunately I don’t think torque at the road wheels is often specified or compared. Peter

Researched for the blog.

It is software controlled with torque mapping and generally customisable using power settings. So eco modes generally would use lower torque increments compared to a sport mode. By merely connecting an obd dongle it is possible to get an idea how the settings differ. Some makes like Tesla even allows you to upgrade to an higher torque mapping (Acceleration Boost).
