The New Model S with the latest upgrade.

Just when you thought Tesla’s Model S couldn’t get any faster, it just did.

In a long awaited announcement, Elon Musk revealed an upgrade to Model S P85D that would enable an acceleration time of 0 to 60 in just 2.8 seconds.

The fastest acceleration time previously belonged to the vehicle’s “insane mode” which could achieve the same speed and distance at around 3 seconds.

Now the “insane mode” has been replaced by the “ludicrous mode.”

The newest upgrade will be optional at the additional price of $10, 000. Existing P85D owners will be receiving a $5, 000 discount plus installation and labour for the coming six months.

In a press release from Tesla, the improvement that made this new feat possible was explained.

“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.”

To appease potential buyers with range anxiety, Tesla announced an upgrade that would open a new battery to the public, one that could go for 90 kWh, adding another 15 miles of range to Model S. This improves the capabilities of the previous 85 kWh power pack.

Musk said that the pack capacity would undergo an annual increase, adding “roughly 5 percent per year.” Customers are advised to wait for bigger upgrades unless their “usage is on the edge of the current edge.”

Tesla announces an even faster version in four years called the “Maximum Plaid,” the next generation Roadster.
