Tesla opens Ludicrous battery pack retrofit pre-orders to P85D owners

On Friday, Tesla opened pre-orders for the ‘Ludicrous’ battery pack retrofit upgrade to Model S P85D owners. Tesla announced the ‘Ludicrous’ mode over 2 months ago as a $10,000 option on Tesla’s top performance model, which had become the P90D at that point since the company announced a battery pack capacity increase to 90 kWh alongside the Ludicrous option. The new package enables faster acceleration: 0 to 60 mph in 2.8 seconds.
