Musk to build worlds fastest production car and it's electric.

[doppler (Rick)]

I saw this promo clip and thought yea sure.

But after a bit of googling I found this clip. Interesting stuff.

This will kill a generation of 18 year-olds when these eventually fall into their hands either when they borrow dads keys, or 10+ years secondhand.

Musk is irresponsible IMHO. It would be better if the performance was toned down in return for better range.

Surely, due to the laws of physics, if you don't put your foot down the range IS better

[raymo]

The claimed range is already brilliant, so not much incentive there, and
the car is not cheap, so relatively few kids are likely to get their hands
on one, and lastly the kids of rich parents can already get their hands
on insanely fast cars.[0-100 in around 2.3 secs or so.
I have wondered for years why manufacturers have produced ever faster
cars, when in most countries they can't be used to within cooee of their
maximum performance, although there is of course no limit put on
acceleration.

I’d put a bet on the fact that when autonomous, or, semi autonomous driving is a fully mature and legal technology there will be a condition attached. The vehicles will only be able to travel at the mandated speed limit relevant to its location. It is also my understanding that there are already some vehicles out there that can be speed limited if little Jimmy on his P plates borrows the car. Can’t remember if that tech is an add on or embedded.

I think it is great folk are devoting time and effort into getting the most out of electric powered cars.
Eventually their efforts should mean the cars get better and this will see electric cars more acceptable.

[Shiraz (Ray)]

Agree with Alex - I think that it's clever marketing.

The "Top Gear" crowd in the world of motoring has been hammering electric cars for years and Musk is just trying to show even the most committed petrol heads that the future is not petrol - by invading their last bastion, extreme performance.

[xelasnave]

All an electric car needs is a "broooom" recording to satisfy whatever it is that it will satisfy.

All we need now is a Hollywood action movie showing the hero silently burning rubber and driving the girl quietly away into the sunset.
We need to make quiet the new cool.

Hi Raymo,

A U.S. colleague owns a Tesla Model S P85D (circa late 2015) which will
do 0 to 100kmph in around 2.9 seconds.

You can find no shortage of acceleration reaction videos, such as this one, on YouTube :-
https://youtu.be/vFwxlCp_wpU

A Ferrari 458 will out do a Tesla P85D over a quarter mile.
But the enormous torque provided by the electric motor of the
Tesla P85D's provides initial acceleration in a different league :-

In May this year, a Chinese NIO EP9 all-electric supercar broke the Nurburgring lap record :-

IEEE have a story today on the Tesla truck and the Roadster sports car,
which is the supercar cited in Rick's original post.

That story is here :-
https://spectrum.ieee.org/cars-that-...new-sports-car

TV news last night showed the glitzy launch of both vehicles
by Elon Musk and highlighted the "production hell", as Musk put it,
of the delays in delivering the more modestly-priced Model 3 car.

The news clip featured Musk camping out on the roof of the Gigafactory - the
largest manufacturing building in the world - spanning an area equivalent to
107 American football fields.

Dec 2016 IEEE story on the Gigafactory, which produces the batteries, here :-

That's a big part of the whole power effect, the exhaust noise or "note" as we used to call it in the 70's. People used to spend a lot of money on their exhausts to get the best sound. You can't beat the sound of a pre-catalytic convertor, v8 twin system exhaust, purring along the highway.

I guess they will also have to change the definition of a car.


car
kär/
noun
noun: car; plural noun: cars
a road vehicle, typically with four wheels, powered by an internal combustion engine and able to carry a small number of people.

Ten thousand newton-metres of torque.

TEN ..... THOUSAND ... newton-metres.

Hi Julian,

That will be at the wheels though, after gearing.

By comparison, the Model S P85D delivers about 931 Nm from the power unit.

I Googleed and from what I could see, the Model S P85D has a gear
ratio of 9.73 to 1.

So 931Nm * 9.73 would be 9058Nm at the wheels on the earlier
Model S P85D. So the new Roaster would be about 10% more.

You definitely want the tyre grip to match.

I recollect watching a video of Kimi Räikkönen when they were testing the current
F1 power units a couple of years back at Barcelona.

Rounding a corner in the Ferrari, he must have planted the foot a little too much or too early
and with the additional torque provided by the Energy Recovery Unit it spun up the tyres
and the car went sideways into the barrier. So even for an experienced rally car driver, it requires
a fine touch to drive a car with that much torque. For the rest of us, computerized traction
control on a production car like the Tesla would come to the rescue.

[Shiraz (Ray)]

here is a bit of the anti-electric propaganda that the new car is trying to overcome.

I notice the top gear link is from 2011, so not really fair????
To me its linked to modern advertising more than anything else.
Think sport ie football in Vic
In the old days, teams racked up wins and became good and people went to watch. Momentum grew "based on actual performance", and the media then proclaimed them good.
These days, paid media/propaganda proclaims something is good "and you should go and watch" just in case it is.
When electric cars go from propaganda to normal day to day reliability ( at an affordable cost ), it will all change.

The top gear mob hopefully belong to a dying past.

All these folk who like fast road cars are pathetic.
Put them on a race track and I bet they could not go half as fast as they think they can...let's face it if they had any talent you would think they may have got a race drive but of course they won't because they are too immature and undisciplined to cut it with real drivers.
I was going to say they act like children but that would be wrong as most children have much more sense than that hopeless trio can assemble between all of them.
However they appeal to the masses which says a great deal about those who follow their sad antics.

Now give the electric car a broooom broooom switch and perhaps you could win them over.

Little men seeking to be noticed by making believe they have some sort of driving ability...look at me look at me complex.

There are those who embrace change who lead the human race to better things and those like the immature trio who...well what can you say for them that by their actions they don't say for themselves.

Sadsucks they be.

[xelasnave]

I would like to see all cars with a system that enables their speed to be regulated by WiFi to hold speed within 10% of the legal limit of the road they are driving upon.
High performance road cars need to be outlawed...we can't have guns but speeding drivers kill many more humans...its is weird how the populace tolerates reducing guns in the community but let folk behind the wheel of cars most should not be allowed to drive.

Alex

[doppler (Rick)]

To pass a drivers licence test you only need to be able to drive to the road rules. It is illegal to learn how to actually handle a car in all driving situations, that's hooning. So most people come unstuck when they hit a greasy corner or a bit of gravel or another driver does something stupid and they don't have the skills to avoid an accident.

[AndrewJ]

Gday Alex

to be regulated by WiFi to hold speed within 10% of the legal limit of the road they are driving upon.

A noble option, but will never happen as that would require "the system" to maintain the required data behind it in realtime, and then what is the "legal limit" as that changes based on the phases of the moon, roadworks in process or if an emergency vehicle has its lights on in a specified location ?????????
Todays models ( driven by beancounters ) are maintenance by failure, ie you dont spend money until something fails ( and hope it isnt too expensive when it does) ie You dont actively "try" to prevent failure.
Until that mentality changes, systems like you propose will never be feasible.
A good example in melb is the constant calls to radio stations re the chaos on our FEEways, where "automated" signs can post 60 kph on the left side of the road but 80kph on the right
meantime a plod has pulled someone over and has their lights on which means you really need to slow to 40 ??????
Computers are only as bright as the monkeys we pay to program them.
