Tesla has introduced a handful of updates across its Model S and Model X ranges this week, namely improving the acceleration of its non-performance variants.

Headlining the changes is the significant improvement in terms of straight-line performance for the Model S 75 and 75D, which both can now accelerate from 0-100 km/h a full second quicker than before – 4.6 seconds and 4.4 seconds, down from 5.8 seconds and 5.4 seconds respectively.


The same goes for the larger Model X 75D available only in dual-motor ‘D’ guise – which can now sprint from 0-100 km/h in a claimed 5.2 seconds – down from 6.2 seconds.

The performance improvements have been achieved through a combination of software and hardware updates, meaning the changes apply to new vehicles from the factory rather than current examples already on the road.


Additionally, the Model S 100D and Model X 100D cut the benchmark 0-100 km/h sprint time to 4.3 seconds and 4.9 seconds respectively, down from 4.4 and 5.0 seconds.

Meanwhile, the Model X also sees the introduction of a new seven-seat option that allows the second and third rows to fold completely flat, however the Australian seating specification remains unchanged.
