The standard Model X certainly doesn't lack for performance, with the dash to 60 miles per hour possible in just 3.8 seconds and a top speed of 155 mph. For those willing to tack on $10,000 to the starting price, the Ludicrous Speed upgrade knocks the sprint to 60 down to a claimed 3.2 seconds and a quarter-mile run of 11.7 seconds. If accurate, that's even quicker than Consumer Reports managed in a Model S P85D.
The Model X's standard equipment includes blind-spot monitoring, access to Tesla's ever-growing Supercharger network, and sensors for the falcon doors for opening them in a garage. The Signature Series tacks on a ton of extras, like the Autopilot semi-autonomous driving tech, an air suspension with GPS memory, upgraded sound system, and ventilated and heated seats.
Beyond the Ludicrous Speed upgrade, there are two other options available on the Signature Series. A Tow Package for $750 adds a two-inch hitch receiver, seven-pin connection, and Tow Mode software. According to Inside EVs, this allows the Model X to haul up to 5,000 pounds. Also, the Subzero Weather Package for $1,000 includes a heated steering wheel, three-zone heaters for the second and third row seats, heated washer nozzles, and wiper defrosters.
The Model X is built on the same production line as the Model S. Tesla expects that getting things going on the CUV could slow down overall production in the latter part of this year. The first deliveries are expected in late September, according to Automotive News.
