Tesla Ludicrous Speed Option

[Palumboism]

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!  

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?

[Palumboism]

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.

A bit more than 15 and the number of free superchargers is increasing every month:

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

Don't get me wrong, I love it. Pair an electric car with good range and 200 more nuclear power plants nationwide and I am in, baby. I will charge that fucker at home at night.

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

   It's a fucking fuse.

[The Grim Lifter]

  It's a fucking fuse.

[Necrosis]

  It's a fucking fuse.

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.

[Tapeworm]

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.

[denarii]

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

[Tapeworm]

How'd the fuses hold up?

[Palumboism]

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!

I stand corrected, that's pretty cool.
