Supercar Blown away

[JuST Peter]

Here we go, next they'll have electric cars that take you where you want without you having to drive them.


 

This  will blow your mind!!!!

 

 
 

 

It's  on — a drag race of epic proportions. It's the world's fastest four-door  sedan, the Tesla Model S P85D,

against  Australia's fastest four-door sedans, the Supercheap Auto Racing Holden  Commodore V8 Supercar

and  the Walkinshaw Performance W507 HSV GTS.

The Tesla Model S P85D  rockets from 0-100km/h in just 3.3-seconds, while the V8 Supercar does it in  3.4-seconds,

but  weighs just 1400kg with the driver.

Strap  on as we see who wins — USA v Australia.

Without watching the clip (I've seen others) I'd hazard a guess and say this Tesla has the twin motor or AWD version.

wow does it come with a long extension lead though... 

[JuST Peter]

Alan, it has a 375 kilowatt motor in the back and a 193 kw motor in the front and yes, it AWD as well so you guessed well.
As for range, they say it's good for 400k's before needing a recharge

Seeing a field of these cars on a racetrack would be as boring as watching grass grow.... the silence would be deafening, as the sound of the V8s is what draws 90% of the crowd.... the other 10% are there for the smell of burnt fuel 

Awesome piece of machinery! 

Totally useless in an all-electric 500 enduro event tho.... no one would be prepared to wait a few hours while the cars were all in the pits recharging

What I've always wondered about these (and I'll admit, I'm no engineer!) is why can't they recharge themselves as they go along? Isn't that what an alternator/stator does in a regular car anyway? Maybe their power need is just too great?

I was at the PMA show last Friday and someone was spruking an electric car (...at a photographic trade show...???), made me wonder just how much juice it uses to recharge, could imagine my energy bill skyrocketing beyond that of the lazy old diesel bill!

Good question.

The reason they can't recharge is because of the Conservation of Energy Law. It takes energy to turn an alternator. The electric cars do generate electricity when they are braking or when decelerating. They do this by turning the *motors into generators as they brake and use the momentum of the vehicle as an energy source. *That is what regenerative braking means in the brochures.

So when your diesel is running most of the energy from the engine is pushing your vehicle along the road and a little energy is being used to recharge you battery. The battery only need s little because the energy required to run lights and start the engine is small compared to the energy to push a vehicle along.

I have thought it might be possible to put Recharging loops under the highway and inductive pickups in the vehicle and pump charge as the vehicles pass over the loops.

I don't understand why hybrids don't use small diesel engines. Torque and constant speed are required to generate electricity. Diesels are great at doing that. Trains are diesel/electric for a reason.

With Tesla the recharge stations are free......takes about 30 minutes.

They do this by turning the mirrors into generators

I want some of those mirrors..

I think you mean motors..  Its called regenerative braking by the way..

Attacked by the auto-terrorist again. That and pain meds.
Yes. I meant motors. And I also meant to say that's what they mean by regenerative braking on the brochures.

GM-H brought out the Volt  back in 2012 which used a combination of electric power and a 1.4 petrol motor which would kick in as a generator after the on-board electric power was exhausted and start recharging the batteries, so in essence it was doing the same thing as the diesel/electric trains.
Trouble was, at $48000 - $57000 it was a little too much for the local market and over the last three years didnt even make 300 sales, so GM-H has scrapped plans of bringing any more into the country

Thanks Brock.

And season 2 starts in a couple of days.
