The Tesla Thread

I don't think you ahve a clue about 1 peddle driving, average us mpg or how you didn't read the report, miss the bit about the improvements and continued improvements since the last report 3 years earlier.

On top of that your posts where nothing about some people might be better off not buying even yet and waiting a few years.

You were caught talking utter rubbish just admit it.

Yes they are and no they havent, if you want to selecetively rate a minority of studies be it. But the vast majority show the total opposite. Nothing but CT arguments like your last few posts have all been.

Oh and lol how clueless can you be, EVs need brake change far less often than ice vehicles.

How do you figure that out? The brakes are the same as a normal car. EVs are generally heavier, so more braking force is needed. Therefore more dust and faster wearing brakes. The only way to stop the dust is using ceramic pads.

EVs have regenerative braking, which is many times more powerful than engine braking. Shows how little some people know. Brake pads on EVs last many times longer.

I'm not talking rubbish, we've both posted links showing the environmental benefits of EVs aren't as clear cut as many make out.

Sure, things might get better, particularly if renewables are the predominant investment for filling the generation gap that will need filled by the mass up take of EVs in the next 20years.
 
They are only going to be greener if people keep them long term. Someone who keeps their classic V8 running will be doing a lot less damage than someone who buys a new EV every 3 years. But that is hard to spin politically and the car industry won't like it.

Lol more utter rubbish. You relay have no clue do you between that and the brakes. What do you hunk happens after 3 years, that they crush the car for scrap. No it goes on to the second hand market and someone else uses it.
 
Yes and then they will keep it a couple of years and sell it, probably ending in it being scrapped within 10 years. They don't go on to the used market and stay there forever.

Lol, why in 10 years, what do you think happens with your v8s. Your post is embarrassing.

The other issue is EV's being bought for inner city driving and never getting the miles on them to reach the break even point.

They should actually make that a requirement so people can make more informed decisions, though I guess the main thing is actually getting shot of diesels out of town centres altogether as the particulates in the exhausts are horrendous.

Show me a link to the study about break dust.

I'm pretty sure I know the one you're on about; done by a first year uni student, deeply flawed and widely trashed. It didn't actually test any vehicles. IIRC it was along the lines of "Lorries produce more brake dust than cars. Lorries are heavier than cars. EVs are heavier than normal cars. Therefore they must produce more brake dust".

Most breaking in an electric vehicle is done using the motors. The mechanical breaks are only used for the last 5-10MPH (it varies by vehicle). Some prototypes don't even have mechanical brakes.
 
On emissions, here's an up-to-date link:

https://www.afdc.energy.gov/vehicles/electric_emissions.php

May 2017

For comparison, the latest published UK fuel mix is:
Coal 17%
Natural Gas 32.3%
Nuclear 23.7%
Renewables 24.3%
Other 2.5%
Figures updated August 2016

Which is considerably cleaner than the US average.

Also, with EVs the consumer has a choice; an entire market of suppliers with varying fuel mixes. An EV doesn't have to be as polluting as the national average.

There's reports of those on over 100k to still be on the original pads, the pad wear is significantly less for an EV

Like I hinted at earlier... you have no idea what you are talking about? How do you think a Prius recharges on the basis if doesn't plug in? Same with EV, better infact as the massive batteries can take decent charge rates to slow the cars at an appropriate rate, it doesn't eliminate the need for friction brakes but a huge reduction.
 
I honestly think until battery technology moves on, electric vehicles are very limited. What if you have one car and need to dash off somewhere in an emergency, yet it's not charged? I can see the appeal if it's one of a number of vehicles in a household, but that seems to be a massive obstacle for me at least.

I like what Tesla are doing but I think once the Germans get things off the ground, they will be able to eclipse them based on the infrastructure they already have in place globally.

The Model 3 looks ok, but the rear of it seems very awkward, a bit like the Model X. I think they could have done a better job.

It'll be interesting to see what it will cost in the UK too.

Thanks for sharing.

So break even point is somewhere between 45-70,000km - smaller cars taking longer presumably because of increasingly frugal engines.

The drop off with a cleaner fuel mix is considerable though. Our fuel mix is improving at quite a fast rate. And consumers can choose how clean or dirty the electricity they pay for is. Ecotricity are at 288.4g CO2/kWh. Considerably lower than the study's 521g. You don't get that choice with a combustion car.

Battery Electric Vehicles aren't a magic bullet. But they are certainly better in many regards. And they're the best green car tech we have now.

To my mind, the biggest environmental advantage BEVs have is in lowering localised pollution, particularly in dense population areas. The difference on that front is huge and desirable.

A plug in hybrid can do the same with ev mode in city and engine on motorways. Most OEMs see this as the future (and so do the government if you ignore the misleading media articles )
