The X306 generation marked Jaguar's first factory-supercharged sedan, the XJR. Launched in 1994 for the 1995 model year, it combined the X300's retro-inspired styling with serious performance from a 4.0L inline-6. The Eaton M90 supercharger boosted the AJ16 engine to 321 horsepower, giving the elegant sedan a 0-60 mph time under 6 seconds.
Collectors appreciate the X306 XJR as a significant model in Jaguar's history. It was the last XJ to feature the legendary inline-6 engine and the first to receive forced induction, a combination that wasn't repeated. Build quality improved significantly under Ford's ownership, making these cars more reliable than their predecessors while retaining the classic wood and leather interior.
The market for these supercharged Jaguars is currently very accessible, with average prices hovering below $10,000. While many have been driven and modified, low-mileage, original examples are becoming harder to find and command a premium. They represent a strong value for a hand-finished performance sedan with classic looks and modern usability.
Buying Tips
- Check for rust thoroughly, especially around the sills, wheel arches, and the front and rear windscreen surrounds.
- Listen for a rattling sound from the engine on cold starts, which can indicate failing upper timing chain tensioners.
- Test all interior electronics, including the climate control, power seats, and instrument cluster for any warning lights or dead pixels.
- Inspect the adaptive suspension (CATS) dampers for leaks and check for worn front upper wishbone bushings, a common wear item.
- Listen for noise from the supercharger snout, as worn bearings or a failing coupler will require a rebuild.
Prices for the X306 XJR range from around $500 for projects to over $18,000 for concours-quality examples.
