Feigned Accuracy



On the previous page, the density of gasoline was indicated with 0.7 kg/dm3 and a little more. This was not a slip of the tongue, but should point out that it is difficult to describe precisely the density of fuel even two places behind the comma. There are different qualities, which the refinery can not completely compensate.

Our theme is accuracy. For example, the current e-Golf, which has just been introduced, now can use 35.8 kWh of energy. Or has this to be deducted by 20 percent, which would correspond to 28.64 kWh? Probably, because the VW group, which is currently battered by the diesel exhaust gas scandal, is struggling here not to promise too much:

"In its new e-Golf, Volkswagen is using a new lithium-ion battery whose energy capacity has been increased from 24.2 kWh to 35.8 kWh. In terms of an annual average that is relevant to customers, the e-Golf will now cover up to 200 kilometres or more in everyday driving on one battery charge – depending on driving style, the use of air conditioning and other parameters2. Its driving range in the New European Driving Cycle (NEDC) is 300 kilometres. This enlarges the car's radius of activity compared to its predecessor – by 50 per cent, depending on driving style and usage."

And at a range of 200 km, the car should consume 14.32 kWh per 100 km, which is significantly more than the 12 kWh we have assumed, while looking for the lowest possible consumption. However, it should be interesting how the VW engineers have managed the 9.55 kWh per 100 km in the NEDC test. By the way, for the new Ampera-e with 60 kWh (48 kWh), Opel gives 520 km (NEDC) and 380 km behind closed doors.

As a continuation, you should now look below at Bjørn Nyland's trip with the old e-Golf through Norway at winter time with a final score of incredible 23 kWh per 100 km.

Please, never fall for this 'up to', because it promises almost everything and holds nothing. The advertisements are full of such and similar non-sayings. This is why it was perhaps not quite fair to pick up the electric cars. In any case, the next page will go on with hopefully practical facts. 02/17
