Full article at:On Friday, Tesla announced a suite of upgrades to the Model S sedan. The headline improvement was the introduction of “Ludicrous Mode,” which betters the “Insane Mode” the company created for the high-performance P85D all-wheel-drive, twin-motor version of the car last October.
Insane Mode was truly insane. Here was a four-door luxury car that could do 0-to-60 in a staggering 3.1 seconds. That’s supercar velocity.
But Ludicrous Mode cranks the Model S up to 11. Yes, it truly does. Through some complicated electrical engineering and the addition of a 90kWh battery option, the Model S P85D can, according to Tesla do 0-60 in 2.8 seconds, breaking the highly symbolic 3-second barrier and serving up straight-line performance reserved for roughly half a dozen so-called hypercars, such as the Ferrari LaFerrari and the McLaren P1 — exotic beasts that cost more than a million bucks.
The P85D — actually, it should probably be called the P90D, with the 90kWh upgrade — costs a bit more than $100,000.
Now that’s ludicrous!
Even more astonishing is how Tesla was able to achieve this level of velocity. As CEO Elon Musk related on a conference call Friday, and in a company statement, Tesla wasn’t exactly trying to create the kind of acceleration for the Model S that would rival what Musk gets from the the products of his other company, SpaceX, and its rockets.
Rather, Tesla was trying to make the powertrain (that’s the battery pack plus the electronics and motors that drive the wheels) last a million miles (itself an impressive goal). This process entailed improving a fuse that would typically melt when sucking too much power. A “smarter” fuse solved this problem — and serendipitously now enables the P85D in Ludicrous Mode to continue, effectively, accelerating in Insane Mode past the previous Insane Mode limits.
It’s double Insane Mode!
