With the Model S P100D becoming even quicker, there’s no need for the P90D anymore, right?

Elon Musk announced that the already blistering fast P100D variant of the Model S will feature a “Ludicrous Easter egg” that will unlock the vehicles’ full performance, making the P90D obsolete.

According to Electrek, Tesla will phase out the P90D and make the “ludicrous” upgrade only available with P-branded cars..

But that’s not the only significant change dedicated to the full-size, all-electric sedan, as Tesla has quietly added an all-glass roof option for the Model S, available for $1,500 – while the panoramic sunroof option, which lets you install a roof rack or satellite radio, is still priced at $2,000.

The add-on removes the crossbar over the vehicle’s B-pillars, offering an airy, and unobstructed experience. Regarding a possible greenhouse effect, Tesla claims their tinted glass blocks 98 percent of UV rays and 81 percent of heat, making it a viable proposition even in a warm climate. Moreover, the car maker will most likely offer a sunshade option, at some point.

It looks like Tesla’s recently-created, in-house glass tech group is hard at work. Like its big brother, the upcoming Tesla Model 3 is expected to feature a similar option.
