Tesla has introduced several performance upgrades to the Model S and Model X, which come courtesy of new software and hardware rollouts. According to Electrek, only new vehicles being built today will receive the enhancements, and not previously-built vehicles.

For the Model S, the base version Model S 75 and the dual-motor Model S 75D will now accelerate from zero to 96 km/h (60 mph) much quicker than before. The former now does so in just 4.3 seconds (down from 5.5 seconds), while the Model S 75D accomplishes the feat in 4.2 seconds (down from 5.2 seconds).

The Model S 100D also sees a slight improvement in the sprint, setting a new time of 4.1 seconds, which is 0.1 seconds quicker than before.

Moving on, the dual-motor-only Model X also sees a significant improvement in terms of performance. The Model X 75D completes the zero to 96 km/h dash in 4.9 seconds (down from 6.0 seconds), and the Model X 100D will do the same in just 4.7 seconds (down from 5.2 seconds).

The all-electric SUV also gets a new seven-seat configuration, where the second- and third-row seats can be folded flat. The new seat configuration will be a US$3,000 option, and joins the still-available.
