Electric Vehicles (EV) Thread

[lindosfan1]

The idea that governments can say no more petrol/diesel cars after a certain date is ludicrous. Look around any town and there are many streets where people live they park in the street, sometimes a fair way from their house. I live in a over 55 retirement complex we have parking spaces outside who is going to pay for fitting charging points, how will the electricity be metered.
How will people afford these electric cars, the second hand market will not exist due to battery age and use. Buy a new car every ten years because the battery has lost its power. The cost of new batteries as seen in the previous post of a man blowing up his car is horrendous.
The politicians to day live in a dream world, also why are they not pushing for hydrogen cars makes more sense no waste and no batteries to dispose off when they are old.
The idea of banning fossil fuels is commendable, but have a sensible plan that will work. Batteries will increase in quality, however there is no plan for charging everywhere (public charging points will not work) and disposal of batteries as not been resolved.

The latest on electriic cars. From the daily fail
A finnish man blew up his 2012 tesla after being told he had to pay £17,000 for new batteries.

According to the various articles on this, it was a modified second hand car. He'd only driven it 900 miles before it started to have problems. Also, even if you had to replace an entire battery for a Tesla 3 that was out of warranty (you normally only replace the defective cells) it should cost around £9-12,000, including parts and labour.

We don't know what modifications were done but the car also had other problems (water leaks and different error codes) so maybe the guy just bought a lemon.

I'm wondering if there's more to this than meets the eye - I mean, I'm certainly no Elon Musk fan but I'm not sure I would have bothered to helicopter in an effigy of him to blow up with the car (which they did) just to make the point.

What are some opinions about Hydrogen powered vehicles?

The efficiency of hydrogen is very poor compared with battery electric vehicles.
If you use electricity to make hydrogen and then use it to power a electric vehicle through a fuel cell, it's something like a third of the power recovery of using a battery. If you burn it in a internal combustion engine it's even less efficient than that.
Battery electric vehicles are very efficient, something like 70% of energy makes it from generation source to the wheels of the car. Fossil fuel powered cars are a disaster, you're lucky if 10% of the energy in the ground gets to the wheels, so about 90% of the oil extracted has been wasted!

I may wait for the cigarette pack size portable fusion reactor that slips into a slot in the engine compartment.

OK, I'll keep walking and pedaling.

Although the argument for hydrogen fuel cells is not fully proven, the obstacles (cost and environmental impact) are reducing all the time. This article gives a fairly good insight as to where we are today and what might happen in the future.

I don't want anything that I have to water, feed or mow.

Just looked at the Lotus Evija. 100% made in Britain. 2,000 HP. Top speed of 200+ mph. 0 - 62 in 3 seconds 9 secs will get you to 186 mph. 215 mile range. Charging takes 18 mins (if you can find a 'fast charge' station)

Has to be the number 1 electric car. (look how far we've come since Sinclair launched his C5).

Saving all my coins with a target of £2 million plus. I wonder how long that will take!!!

Unfortunately, Lotus hasn't been British for quite some time.......

[HHTel]

Come on Pharvey. MADE in Britain!

To be more specific:

The Lotus Evija electric hypercar is a step closer to reality. Lotus has set up a manufacturing facility for the car at its home base in Hethel, United Kingdom. The facility is currently building prototype cars, but series production and the first customer deliveries will begin this summer, Lotus said.

Where can you drive 200+ MPH?

[HHTel]

Well the Autobahn immediately springs to mind. I've done 160 mph but that was in a BMW and that was flat out. The Isle of Man has no speed limit but whether there's a road good enough for that speed I wouldn't know.

There are others I'm sure.

Oh, I'm just being pedantic - and pi$$ed off with British companies being sold off.... Especially to the likes of China and Russia.

Well the Autobahn immediately springs to mind. I've done 160 mph but that was in a BMW and that was flat out.

The first time I drove on the Autobahn, I hit around 140 mph and was almost sucked up a passing Porsche doing Warp 7 or so.......

The Autobahn is nothing like it used to be and now has many speed restrictions on certain stretches or those imposed during certain times of day. The power of the major car companies however will ensure limitless speeds on certain stretches will stay for some time yet.

The fastest I've driven my car (not current model, but an AMG Merc) is not quite 160 mph, but pushing it - this was at a "Track Day" at Castle Combe Race Course in the UK. One of the safest places to drive fast - you must be qualified, you must through a further safety course as does your car and all other drivers. A little safer than unregulated on the roads.....

That said, 200 mph is quite a step up!!

[Dannie Boy]

I guess that in pushing the boundaries, more humble cars that the majority of us can afford will benefit by improved efficiency (greater range with adequate performance) and prices will eventually come down. Then, all will need is for the Government to provide sufficient incentives to get a workable infrastructure!!
