We nearly missed this too.
The Tesla Model 3 launch is a big deal, but that hasn't stopped Elon Musk from making sure the Model S and Model X also receive some loving. First reported by Electrek, Tesla has updated both its Model S and Model X with new performance updates that essentially make the non-performance versions of both even faster. Tesla confirmed to Electrek this information, stating that the vehicle updates were both of the hardware and software variety, and it's the base versions that'll benefit most.
The Model S 75 and 75D each have improved 0-60 mph times, 4.3 seconds (down from 5.5) and 4.2 seconds (down from 5.2), respectively. The Model S 100D now does that same sprint in 4.1 seconds, previously 4.2. As for the Model X, the 75D and 100D do the 0-60 sprint in 4.9 (down from 6) and 4.7 seconds (down from 5.2), respectively. As for what's new in hardware, the Model X offers a seven-seat configuration for $3,000, allowing for the second- and third-row seats to fold completely flat for maximum cargo space. There are several reasons why Tesla is the fourth most valuable car company in the world right now, and one of them is that it consistently updates existing product.
