Tesla is well-known for pushing the envelope. Earlier this year, the carmaker unleashed the Model S P85D, which came with an option literally called Insane Mode. But that wasn’t enough. Tesla CEO Elon Musk wants to go faster.

During a conference call on Friday, Musk announced a series of battery upgrades, including a new Model S, the P90D, which goes so fast that it comes with a Ludicrous Mode. So fast that it pins riders back at 1.1G, which is faster than the feeling of free-falling. Faster than any commuter car has any right to go. But I digress.

Equipped with 762 horsepower, the Model S P90D is quick enough to rock a quarter mile in 10.9 seconds. Even Dominic Toretto, who lives his life a quarter mile at a time, would approve.

Musk explained how Tesla achieved the breakthrough during the call, saying the company devised a “smart fuse” for the new 90kWh battery pack.

“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,” Musk said. “It constantly monitors current at the millisecond level and is pyro-actuated to cut power with extreme precision and certainty.”

What that means for drivers is a 10-percent improvement in 0 to 60 mph over the previous model (0-60 in 2.8 seconds), and a faster time to 155 mph, which is an absolutely ridiculous speed. Or, as it’s being called, Ludicrous.

The new mode actually works in conjunction with Insane Mode, Musk explained. Once you hit about 30 mph through Insane, Ludicrous Mode will kick in, allowing drivers to drive at supercar speeds. The Model X—no surprise—will feature Ludicrous Mode as well, though its o to 60 mph is clocked at 3.3 seconds, which is still incredibly quick for an SUV.

The Ludicrous Mode will also come with a price to match: it’s a $10,000 option for the car, which means you have to really love going fast to upgrade. Owners of the Model S P85D can upgrade their vehicles battery for $5,000 before installation fees..
