Tesla reduces the price of the Ludicrous upgrade from $7,500 to $5,000

Tesla sent out an email this weekend to Model S owners on the waiting list for a retrofit of their Performance Dual Motor Model S to enable the ‘Ludicrous’ mode. In the email, Tesla explained that due to parts and process improvements, the company is now able to offer the upgrade at a reduced price of $5,000 instead of the previously announced $7,500.

The Ludicrous upgrade consists of two improvements to the electronics of the Model S’ battery pack. The first improvement is the replacement of a standard fuse to an “advanced smart fuse” which enables the monitoring of current to the millisecond, and makes it possible to cut the power with “extreme precision”.For the second improvement, Tesla replaced the main pack contactor to use Inconel instead of steel. Inconel is a space-grade superalloy well suited for extreme high temperature environments. This superalloy is primarily use in the aerospace industry, and one of its more famous use is in the novel manufacturing process of SpaceX’s SuperDraco engine.

The two improvements combined allow Tesla to increase the max power output of the Model S’ battery pack from 1300 to 1500 Amps.

This upgrade should allow a Model S P85D to accelerate from 0 to 60 mph in less than 2.9 seconds.

Here’s the email in full:

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 emailingOnlineOrders@teslamotors.com[1] . 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.
