Assuming you caught it, this was mentioned on the sly in an article that we published yesterday; a firmware update for the Tesla P85D performance-oriented Model S will boost max power output and top speed, likely to be released within the next few months.
Green Car Reports commented on the coming update, citing a statement from the electric carmaker itself. This update is expected to boost the Tesla P85D’s performance “above what anyone outside Tesla has experienced to date.” As it stands, top speed in the Tesla P85D is electronically-limited to 130 mph.
The statement indicates a new top speed of 155 mph, as well as a significant bump to high speed performance. Right now, the engineers at Tesla Motors are working to complete validation testing for the free upgrades.
Previously, we’d reported on a 4WD dyno run of the Tesla P85D which revealed a peak torque of 864 ft-lbs “at the wheels,” according to DragTimes. But don’t be too quick to believe it; that number seems suspiciously low for a peak torque figure, unless it was in-fact a computed “at the crank” torque figure. That’s equally suspect with no mention of estimated parasitic loss percentage or final drive ratio.
We look forward to subsequent, more credible dyno runs in the future.
