If Tesla P85D owners aren't satisfied with their cars insanely accelarating from zero to 100 km/h in just 3.2 seconds using the "Insane Mode" on, then they might feel more accomplished using the upgraded "Ludicrous Mode" – it will make their cars go ludicrously fast! The upgraded Tesla S P85D will do be able to reach the 100 km/h mark in astounding 2.8 seconds, which is, according to Musk, that same acceleration that pins you to the seat at a 1.1 Gs. He claims it's even faster than falling.

For the exisitng Tesla P85D owners, this time it will take more than just an over-the-air software upgrade. In the next six months they'll be able to make the upgrade for 'just' 5,000 USD (labor costs excluded), when they take their vehicles to a Tesla service center, but after that, the system will only be available as a factory option on new P90Ds.

According to Musk, this is what the upgrade is all about: "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."

According to Tesla company, owners of the newer, stronger models will be able to enjoy the new, non-Performance-package-equipped 90D—an 85D for a 3,000 USD 90-kWh battery upgrade, which will extend the car's range by 6 per cent. Existing P85D owners could also opt for an upgrade, but at Tesla they feel it's not the most sensible thing to do.

Musk also announced a new rear-drive Model S 70, which is an all-wheel-drive Model S with a 70-kWh battery pack and a range of 420 kilometers. The 235kW motor makes it jump from zero to 100 km/h in 5.8 seconds, with maximum speed remaining at 225 km/h.

Furthermore, Musk also revealed some other information regarding the upcoming models. The first Model X is to ship in two months, while the more affordable Model 3 is to roll out in just over two years.
