Luuudicrous Mode
While working on our goal of making the power train last a million miles, we came up with the idea for an advanced smart fuse for the battery. Instead of a standard fuse that just melts past a certain amperage, which means you aren't exactly sure when it will or won't melt or if it will arc when it does, we developed a fuse with its own electronics and a tiny lithium-ion battery. It constantly monitors current at the millisecond level and is pyro-actuated to cut power with extreme precision and certainty.
That was combined with upgrading the main pack contractor to use inconel (a high temperature space-grade superalloy) instead of steel, so that it remains springy under the heat of heavy current.
The net result is that we can safely increase max amp throughout from 1300 to 1500 Amps. If you don't know much about Amps, trust me this is a silly big number of Amps to be going through something the size of your little fingernail.
What this results in is a 10% improvement in the 0 to 60 mph time to 2.8 secs and a quarter mile time of 10.9 secs. Time to 155 mph is improved even more, resulting in a 20% reduction.
This option will cost $10k to new buyers.

To put this into perspective, here are the 0-60 times of some very fast cars:
2.8 Tesla model S P90D
2.8 Lamborghini Murciélago
2.95 Chevrolet Corvette Z06
3.0 Ferrari 458 Italia
3.0 Porsche 911 GT3
3.3 Porsche Panamera Turbo
3.3 Lamborghini Murciélago
3.4 Lamborghini Gallardo
3.4 Porsche 911 Turbo
Here are some quarter mile times for comparison:
Bugatti Veyron Super Sport 9.9 sec @ 145.8 mph
Lamborghini Aventador 10.4 sec @ 136 mph
Lamborghini Huracán 10.4 sec @ 135 mph (217 km/h) Porsche 911 Turbo S 10.7 sec @ 128.9 mph (207.4 km/h)
Dodge Challenger SRT Hellcat 10.8 sec @ 126 mph
Tesla model S P90D 10.9 sec
Ferrari 458 Italia 10.9 sec @ 131.7 mph
Lamborghini Murciélago 10.9 sec @ 129.4 mph
Chevrolet Corvette Z06 10.95 sec @ 127 mph (204 km/h)

Nice, maybe all the Indians and Asians buying might drive more than 35 mph in the 55 mph zone.

Doesn't mean shit if it can only go 100 miles on a 60 minute recharge ::)

Tesla just announced that it will offer an upgrade to a 90kWh battery on its Model S sedan for $3,000 extra. This represents a 5-kilowatt upgrade against the existing 85kWh model. This turns the car into a "90D" model instead of the existing 85D, offering 300 miles of highway range at 65 miles per hour. Furthermore, Tesla superchargers provide 170 miles of range in 30 minutes and 300 miles in 75 minutes.

Insane launch mode! ;D
It takes about 5 minutes to fill my car with gas and it goes a LEGIT 350 miles on a tank. Get the stupid Tesla to those stats and give me more than 15 recharge stations nationwide and we might be talking. Until then, no.

How many 1/4 mile speed runs before the battery is dead? 3?

The Tesla model S can get 170 1/4 mile speed runs at $.06 per run. I would expect the 85D to get 101 1/4 mile speed runs based on the additional motor and ratio of power between the models.

Their new Roadster will be on the market 4 years from now, probably 0 to 60 close to 2 seconds. Much lower weight and drag than Model S

No Aston Martin's on that list? Surprising. I test drove a Vanquish a few years back, that thing was ridiculous off the line.

How much is the alloy and tech for it though? seems like it's an innovation based on the alloy being able to withstand such a current, while making micro-second corrections.
-
I'm sure they have their reasons but automotive applications don't strike me as the place to use space-age super alloys of unobtainium. Strikes me as a classic case of price gouging for people who want to say they bought the latest/greatest.
The Falcon may correct me here but if for some unknown reason it wasn't possible to just fuse the main supply with a traditional inexpensive fuse of a suitable size and you absolutely had to use something small then couldn't you get the same result with a regular, small fuse on a shunt that governed a relay for the main? The diagnostics don't seem like anything a current meter and a computer couldn't record. And who wants a fuse that requires its own battery to work? If the little battery faults then I guess the car stops dead or it electrocutes everyone. Seems weird.
And shouldn't they have named it The Edison if it uses DC?

To put this into perspective, a typical refrigerator uses 20 amps of electricity.

I drove 265miles yesterday on half a tank of fuel. I was not doing 65mph in a smallish sedan either.

How'd the fuses hold up?

The ludicrous speed upgrade isn't solely through software, they also upgraded the hardware. Basically, the biggest thing preventing a Tesla from going faster is how much energy you can draw from the batteries at once. They upgraded some components to support high current draw and so they can send more juice to the motors.
When you're sending 1500 amps through the system things get VERY HOT. To ensure the car doesn't become catch on fire, you need smart fuses that are 100% reliable and will cut the power when things get to hot. You also need to upgrade some materials to handle the added heat. Trust me, $10K is a bargain to figure all this out safely. This option is in no way essential and is only necessary if you want to drag race.

Great thing of 2015 is that if you have enough money you can get rid of the government, electricity companies (almost) and corrupt maffia like oil majors:
install solar panels on every suitable roof
Put some Tesla home batteries in your garage
Heat and cool your house with electricity
And buy an electric car!
One big middle finger to all those mostly lying a**holes and much better for the environment / your future as well, win win! :)

"The superfast charging time was achieved using technology StoreDot has been developing. This includes biological semiconductors made from naturally occurring organic compounds known as peptides – short chains of amino acids - which are the building blocks of proteins. Similar to those used by body builders to grow bigger faster."

I don't especially care about electric cars but charging a home battery bank fast would be sweet. Traditional charging makes a generator a waste of fuel, but if they get either the batteries or the charger such that it can be done quick... sayonara power company & associated subsidized yet expensive infrastructure, adios array 'o panels.

Now you're starting to understand. Tesla's all about using technology to stick your middle finger at the establishment. The ludicrous speed option is completely unnecessary, but if you can win a drag race against another car, which is supposed to be fast, then why not. 8)

Just two years ago their top model had 416 hp, and now 762 hp....that's a fast increase. Unfortunately the range only increases by 5% per year, but still, it's progress and they're slowly solving the range anxiety issue

China is one of the most corrupt countries in the world. China civil servant = corruption. They're finally started to clean house, hopen they hang the top corrupt people.
All high end products manufacturers have this Chinese economy slowdown and the anti corruption measures problem.
But....considering that China is also one of the most polluted countries in the world, Tesla maybe has one advantage the others don't have: Model S and Model X are emission free

I don't think the chinamen worry much about pollution.

Speaking of electric cars check out this supercar, 'Concept One' by Rimac, small Croatian company.
This car has it all: look, insane power and amazing engineering.

I see what you're saying. The average modern refrigerator uses 725 Watts of power, on 120 volts that would be only 6 amps.
At 762 hp the Tesla P90D uses 567,690 Watts of power, or the equivalent of 783 refrigerators.
The calculation is:
378 Volts * 1500 Amps = 567,690 Watts = 762 hp

Tesla Model 3 May Make Appearance Next Year
By Aaron Cole on July 26, 2015
Despite the absence of a mule, prototype or anything that would resemble reality, Tesla’s Model 3 — or III, however you spell it — will make its debut at the Geneva auto show next year, AutoExpress is reporting.
The BMW 3 Series fighter would be the third model from Tesla, and perhaps the first built in a European factory. Representatives from Tesla said they would consider building the Model 3 on the European continent once the automaker started mass producing its three models.
In an interview with AutoExpress, Tesla CEO Elon Musk said the Model 3 would be around 20 percent smaller than the Model S and would have a range over 200 miles.
Musk said the car would sell for around $35,000 and performance — from the car company that just announced “ludicrous speed” in the Model S — would be on par with the M3 or M4.
The Geneva auto show begins March 1, 2016.

Recharge time and range are the 2 biggest problems now with all electric cars.
I suspect placing capacitors in the charging circuit would be a huge help and is already done with definbrilators ( sp?) for heart attacks.

Tesla Motors
Superchargers consist of multiple Model S chargers working in parallel to deliver up to 120 kW of direct current (DC) power directly to the battery.
Driving (discharging) and charging use the same systems to move energy out of and into the battery. Supercharging utilizes the car's discharge capacity to flow a similar amount of power back into the battery pack through dedicated high voltage cables. The car’s onboard computer constantly monitors the battery during both driving and charging to ensure that Model S performs at its peak.
Model S is currently the only EV capable of charging at up to 120 kW, which equates to 170 miles of range in about 30 minutes.
