The video covers many of the fascinating details that went into recreating the XKSS. Among them are Jaguar's acquisition of an original D-Type engine block to make new castings, and even replicating the type of type of steering wheel used back in the day. Most of the vehicle is made to be identical to the originals, with only a few changes made for usability. This includes better quality materials for the brake lines, and ethanol-resistant materials for the fuel tank.
Because this particular XKSS was on its way to the LA Auto Show (where we saw it debut at the Petersen Museum), Leno didn't get a chance to take it for a spin. However, snippets of his drive in McQueen's car were added, since it's the same car for all intents and purposes. What Leno emphasizes is how modern the car feels, also noting that it feels lighter than many other classic Jaguars. To see all the details and impressions, check out the video above.
