Tesla Reduces Price Of Model S P85D Ludicrous Upgrade


Tesla Model S P90D

Tesla Model S P90D will be quicker than P85D

Tesla Model S P85D owner Buttermd at Tesla Motors forum presented an e-mail from Tesla on retrofitting the P85D with Ludicrous Mode.

There is good and bad news. The good news is that the price of the Ludicrous Mode retrofit droped from $7,500 to $5,000!

The bad news is that Ludicrous Mode applied to P85D will not give you the same acceleration gain as in the P90D (which cost $10,000).

P85D with Ludicrous will do 0-60 mph 0.2 seconds quicker than the standard P85D (about 2.9, down from 3.1 seconds) – see details. The P90D is listed at 2.8 seconds.

Also, the quarter mile time will be better by only 0.2 seconds (about 11.4 according to Buttermd), while the P90D is listed at 10.9 seconds.

Here’s the email:

“P85D with ludicrous will only do 2.9 0-60 and 11.4 1/4 mile according to latest email

Thank you for your interest in the Tesla Model S Ludicrous retrofit.

As a result of continued improvement on the parts and processes needed to raise the max current from 1300 Amps (Insane) to 1500 Amps (Ludicrous), we are pleased to announce a reduction in the price of the Ludicrous retrofit from $7,500 to $5,000.

The upgrade represents an estimated 10% increase in power over the already insane P85D and provides a 0.2 second improvement over both the 0-60 mph and the quarter mile time versus the performance of your current Model S. Please note the retrofit does not offer the exact performance spec as a new P90D.

The Ludicrous retrofit is available to all P85D customers with original vehicle orders placed before 11am PST Friday 7/17/15. These cars will receive updated badging to P85D with an ‘underline’ to denote the Ludicrous upgrade.

The retrofit will be initially available at the Fremont Service Center with additional Service Center hubs rolling out in early 2016. If your local Service Center is not one of the prioritized hubs, you may alter your preferred location once the list of Retrofit Service Centers has been announced by emailing OnlineOrders@teslamotors.com. The retrofit must be done on site at a Tesla Service Center and cannot be performed by the Ranger Service.

To confirm your retrofit, click the link below to place your order. The pre-order deposit is non-refundable and will be applied to the final cost at the Service Center. When placing your deposit, please remember to enter your VIN and select a Service Center location from the drop-down menu on the Cart page. Please note, the retrofit must be done on site at a Tesla Service Center and cannot be performed by the Ranger Service.

If you have already placed your deposit, then no further action is required at this time.”

So now “just” 5k to drop your 0-60 time 0.2 seconds (along with being able to go, “Hey, look at this! My car has a Ludicrous mode! Woooo!”). Though $5k is probably a drop in the bucket for someone that could afford a P85D.

Well, Ludicrous “Lite”. 10% more horsepower? FYI with traction being the same, a .20 second reduction in the quarter mile should take less than +40 hp in this car. Furthermore, no independent tester has even confirmed a P90D breaking into the 10’s yet in the quarter mile. Seems like some optimistic factory claims?

Tesla has just rolled back its claims of P85D hp by ~200 hp.
“Stop the Press! Tesla announces REAL HP numbers for P85D and P90L”

Hi cousin. Yup, the HP figures now sound realistic 😛

Motor Trend has confirmed the P90D Ludicrous times of 10.9 seconds, in the quarter, and get this, 2.6!!! to 60 mph.


There has been lots of news flow, for PD owners over the weekend. The short of it is an anticipated “Launch control” update, to further scorch the competition. It is reasonable to expect they are being conservative in their “.2” claims, in these emails, since that would leave P85DL .5 seconds off the new P90DL “Best”.

Are the Tesla and Motor Trend times measured using a one-foot roll out or from a standstill?

With a dinosaur foot!

This probability won’t mater to me in that after test driving the Leaf it handed Vdot’s stoplight fetish very well.
