One of the biggest what-ifs in motorsport is the Jaguar XJ13. The car was built for Jaguar's return to Le Mans, but only two prototypes were built and the project was canceled. 50 years later, Design Q and XJ13 replica company Building the Legend have launched the LM69, a ground-up recreation that is built to the FIA rule set that the XJ13 would have competed under. The car is street-legal, with an improved body design, suspension, and a bespoke 5.0-liter V12 based on the XJ13's unit — possibly the last new V12 design we'll ever see in the EV era. Only 25 will be built, the amount required to homologate the car for competition under 1969 rules.
