Mercedes : 194 miles(312km) - 75% of it's claimed range
........Audi : 206 miles(331km) - 81% of it's claimed range
.....Nissan : 208 miles(334km) - 87% of it's claimed range
.....Jaguar : 223 miles(358km) - 76% of it's claimed range
..........Kia : 255 miles(410km) - 90% of it's claimed range
.......Tesla : 270 miles(435km) - 78% of it's claimed range

*Modern diesel cars will do about 75% of their claimed range.
 
Over 300km is more than acceptable for normal driving EVs have come far I’m impressed. The Tesla is just king there’s no two ways about it.
 
I think the real king is the Kia. Tesla went furthest, but it also had the highest claimed range. Niro just destroyed it in the ratio between the claimed range vs real world test figures. It's also cheaper and probably has better build quality than the Model 3 too. And we are talking about a low temperature test here too. Something one would think Tesla would have mastered by now considering they have been in the electric car business for many years.
 
No conclusion about range should be made from this video. And not this is the idea of it. The video wants to show how far the driver can reach on a long journey. But the range is measured in variable conditions. In the video they only drive with the same constant speed which is a profile of a test that eliminates all the advantages of the different motor concepts. Normally the cars accelerate, deccelerate, coast, and drive with constant speed. The first three are missing in this test and it's exactly where the Tesla shines and the rest, especially Kia, fail. Here there are three basic concepts of motors - permanent magnet synchronous (the rotor is made of permanent magnet), induction motor and only Tesla with reluctance motor at the back (at the front I think it has an induction motor, but it is seldom used).
When the car is accelerating the two most important factors(for the range) are the efficiency of the type of motor in full load mode and the weight of the car(the lower, the better).
The efficiency in this regeme goes like:
Induction motor<PMSM<<<<<<Reluctance motor. So Tesla slams here all the others.
Deccelerating is important for the regenerative braking. Here the factors improving the range are mainly power of the elmotor (the bigger the power, the more electricity it generates when braking) and to a lesser extend the weights (the bigger the weight, the more kinematic energy can be converted in electricity). So the bigger the power, the better. (Kia and Nissan suffer here)
Coasting: When an EV is moving, the rotor of the magnet is rotating (except if there is some decoupling system that nobody wants to have in an EV due to added weight, complexity and lowered durability). And here the PMSM suffers, because the rotor is made of permanent magnet and when the car is moving it always creates a rotating magnetic field or with other words the car can not coast and a lot of energy is wasted(the Tesla RM has permanet magnets in the stator, so it does not have this disadvantage). Here the ranking goes like this:
PMSM<<<<<<RM<<IM.
In all this three regimes the Kia will be the worst, and Tesla by far, far, far the best, but of course here in this video they are not considered.
 
The niro is one hell of a car, just helped my uncle buy one last week. Damn thing is cheap as hell and has every damn function on the market, it had a few things my panamera lacks even!

if you just want something to get from a to b in it’s hard to beat.

How is the charging station availability in South Africa? Are there any available in the major cities, or do owners have to charge at home on a normal AC/DC current? I guess Eskom load shedding problems makes owning an electric car a difficult choice in SA.

Normally at home there is no DC current from the grid. DC current is hard to transfer in longer distances (to transfer current a higher voltage is needed and in order to increase it(and later decrease it) is used transformers, which work exclusively with AC. Dc comes eighter from a DC generator, with comutator and brushes, from a battery or from rectified AC.

Very poor, there are a few charging station, not feasible to run a EV as your only car. I’d say we are at least 10 years away from a proper charging infrastructure not to mention the ‘load shedding’ the country is currently faced with. Think even BMW mentioned that the Middle East, Africa and Russia are still some way off from using BEVs as their primary vehicles. BEVs are just not in the conversation

Just as I was typing this we were hit with stage 2 load shedding that 4 and half hours without electricity.
 
Is the EQC really just an electric version of the GLC or was it designed from the ground up to be an EV?
