I like to tow. I also like to know that if the tank is full, that's how far I will get (not shrink with age).

2 minutes at the pump and I'm bored.

I would expect the car to last up to 10 years if buying second hand, but the battery? This is my number one concern. Never have I worried about range or the cost of replacing the fuel tank in my current car.

I wonder if the paint under the bonnet would be better since they don't have a hot petrol engine in there to keep things nice a dry after a good rain storm? I would expect more rust more quickly without a decent heat source under the bonnet.

If the government pay to have rental properties kitted out with charging stations or sockets with enough grunt each time you moved since we're a renting nation in the future... this would also be a factor.

I work mainly at night, so winter night driving would be a big electrical drain I'd imagine if I were to go EV now.

The cost would need to be below $14,000 for a second hand car, that can fill a full tank at 5 years old, and still have 7-12 years up its sleeve when looked after.

I have owned a good number of V8's over the years and it had nothing to do with impressing the opposite gender. The V8 is a very good power plant and not just for the sound or power, it is a very balanced engine, efficient a pleasure to drive. They accelerate smoothly, cruise smoothly and have power that means you climb well, engine brake well and can pass with a great reduced exposure to danger time.

Sounds just like an E car, except for the noise.

V8s are not noisy, they can be made noisy but the V8s I have owned were not.

Love the sound of a V8/V12 engine. Listened to a late model RS6 drive past me and the soundtrack it created was incredible! Don't get me wrong, I love the idea of having an EV but they certainly don't invoke the kind of passion you get from hearing/driving a high performance ICE vehicle (at least for me anyway)

I think lithium batteries in cars (and maybe battery EVs in general) will turn out to be interim technology. I'm backing ubiquitous element like hydrogen and carbon

I'll happily bet against you!

Carbon - burning carbon means pumping out CO2 which is a greenhouse gas that is causing a lot of trouble for the planet we live on.

Hydrogen - dead end waste of time, maybe there will be a few cars running on hydrogen for a short time but that stuff is dead in the water for several reasons.

My money is on battery electric vehicles - currently with lithium based batteries but if better battery chemistries are developed then it could change. BEVs may have a small market share today but in ten years time it will be a very different story.

I agree that lithium batteries will be interim. It's not a case of if, but *when* new battery chemistries are developed. Or some other electricity storage device like supercapacitors. Graphene, for example, looks promising on both fronts. But the general principle of storing energy in a vehicle as electricity rather than chemicals will be long-term.

Hydrogen has been tried in California and has turned out to be a less than interim technology.

Compared to an EV......It's "noisy". At this point, definition is required. :-)

I was talking to guy from Hyundai who was saying they also have a hydrogen fuel cell vehicle coming......but the fueling station costs $2 million....whereas a 50kw EV fast charger can be installed for less than $100,000 (including both electrical prep work and the charging unit itself which is about $45,000).

With fuel cell vehicles, you can't charge them at home. They MUST go to a fueling station......so you'll need lots of them and they are expensive.

On cost and convenience, EVs win.....never mind the risks around hydrogen as a fuel.

Absolutely.

As you know I am a big fan of EVs and as soon as there are models that meet my needs I am in. I also look forward to quiet cities with the gentle hum of EVs

I am not sure why Elon & Co haven't made engine sound an option. There are performance cars around now that add engine sound to the stereo of the car because they are so well insulated that you wouldn't get the "vroooom" experience without it.

Apart from sound, there are virtually no ICE cars around that can compete with the torque of an EV. Even fairly inexpensive EVs can get from 0-50 KM/H quicker than most performance cars.

Its a really nice feeling to have lots of power available instantly at any RPM, I find more pleasure in driving a Tesla than any performance car I have ever driven.

Do EVs have RPM? what is rotating and what is the max RPM?

Sure, the Tesla S85 has this spec in its manual:

Motor
Type AC induction motor, liquid-cooled, with
variable frequency drive
Rating 375 Volts
Maximum Speed 16000 rpm

That has later been increased to 18000 rpm through a firmware update.. :)

It has no gears.

Wonder why they use an AC motor... would have thought DC would be more efficient from a battery power source.

I guess nasty fizzing would ensue if the liquid cooling leaked into the motor....!

Vairies by model.

BMW i3 Max is 11,400RPM, Nissan Leaf max is 10,390RPM. Tesla is quite a bit more.

Single gear ratio, and no clutch, so when you hit max RPM, that is also max speed. This is set well above NZ speed limits.

hyundai are a bit slow.

honda have been trialling hydrogen fuel cell cars for almost 20 years, as have the big euro companies.
