The XE 300 Sport was a special-edition variant of the X760-generation XE, produced from around 2018 to 2019. It uses the AJ126 — a 3.0-litre supercharged V6 petrol engine, shared with other performance-oriented Jaguar models of the era. The 300 Sport sat above the standard V6 S in the XE range, offering a more focused specification with distinct styling and chassis upgrades. The AJ126 is a direct-injection, supercharged unit that delivers strong, linear power — characteristic of Jaguar's supercharged V6 family. The XE 300 Sport is no longer in production, but we continue to rebuild and replace engines for every one still on the road.
