Yes, I do know they do an electric Golf, I also know that when I went in the dealership to ask about it no one there knew much about it and the only statement I got was that there was about an 18 month wait
Ordered Jan 2018, Delivered May 2018. it really wasn't that long a wait, but it's a popular car (36kWh pack) at a fair price.
I'll certainly consider an E-Golf when I eventually need a new car if the price gets better and hopefully they have a little more power. I do like my Golf's but it would be tough to give up the power and sound I currently have. Maybe I'll see your car at a swap one of these days.
I've read a review on the e-Golf from someone who has driven it for about 20000km (in Dutch https://www.autoweek.nl/reviews/artikel/volkswagen-e-golf-2018-4/ ). In the winter the range drops to around 120km with the heating on and driving on the highway at 120 to 130km/h. In the summer the range increases to 270km when driving mostly 60 to 80km/h. Making longer trips requires planning to make it to charging points. Also the range indicator is way off. The author of the review wanted to go to Italy but decided to borrow someone else's car due to lack of charging stations. The author also had problems with occupied and out-of-service charging stations which nearly made him miss a boat (across the sea to the UK) and caused him to drive around with only 3% charge left when he got off the boat again.
I like the way you selectively grabbed information to claim the 120km range. The author states that @ 130kmh into a headwind the range drops to 120km; and of course it does. The air resistance at 160kmph (130 + 30) air speed is 4x what it is at 80, and about double what it is at 115. I think you'd find your petrol/diesel consumption would go up similar amounts at high speeds into a significant headwind too.
On a petrol/diesel car the range doesn't get halved by driving against the wind AND having the heater or airconditioning on. I'm just stating that the e-Golf has a very small battery pack so having some range anxiety is a good mindset especially if you want to make long trips with it in the winter.
The mileage does drop, in exactly the same way, in an ICE car at high speed, just like it does with an EV. And, a headwind adds even more effective speed you're pushing against.
It's pretty easy to understand why.... The laws of Newtonian Physics apply themselves agnostically, not caring if the vehicle is ICE or EV. Friction is Friction, and it requires energy to overcome, and not surprisingly the amount required to overcome increases by exactly the same amount EV or ICE.
As for the use of Air Con and/or heating in an EV, they consume just over 1kW (fixed) when turned up to max (I think I've seen 1.3) my real world results, which is well under 10% of normal driving consumption (around 15-16kW ) being used to heat/cool a car. Yes, it will affect your range by perhaps 10%; similar to what it can in an ICE car.
An eGolf does have only a moderately sized battery (35kWh), vs some of the (Tesla 75-100kWh) competition. It is however, perfect for the vast majority of vehicle trips by the vast majority of the population as other people in here keep showing using hard facts.
Owning an automobile which fulfils the vast majority of my needs is much cheaper than trying to purchase and own something that fulfils every possible need every time. By your logic, everyone would own oversized minivans that seat 12 and carry 2 tonnes, because occasionally they may need to haul move house, or carry 12 people.
