UNUSUAL CARS MODEL GUIDE
The Jaguar S-Type R was the 400PS supercharged flagship of the retro-styled S-Type range. Produced from 2002, it combined the 4.2-litre AJ-V8, a six-speed automatic and restrained body changes with serious high-speed performance.
Quick answer: the S-Type R uses a 4.2-litre supercharged V8 producing 400PS. Its strongest qualities are effortless pace, comfort and discreet styling; its main buying risks are corrosion, cooling and timing-system neglect, gearbox problems, suspension wear and complex electronics.
From S-Type to S-Type R
The S-Type arrived in 1998, using styling cues from Jaguar’s 1960s saloons on a modern rear-wheel-drive platform developed during Ford ownership. Early cars used V6 and 4.0-litre V8 engines. A heavily revised range followed for 2002, bringing improved cabin quality, lighter suspension components and the new R flagship.
Supercharged 4.2-litre AJ-V8
An Eaton supercharger helped the 4,196cc V8 produce 400PS. Drive went through a ZF six-speed automatic to the rear wheels. Larger brakes, firmer Computer Active Technology Suspension and subtle aerodynamic details distinguished the R without turning it into an overtly styled performance saloon.
S-Type R specification
| Version | Powertrain | Buyer’s note |
|---|---|---|
| S-Type R | 4.2 supercharged V8, 400PS | Check supercharger drive, cooling and timing history |
| Early S-Type V8 | 4.0 naturally aspirated V8 | Useful comparison; different gearbox and lower output |
| Later 4.2 V8 | 4.2 naturally aspirated V8 | Shares later improvements without the R supercharger |
How the R differs from an ordinary S-Type
Beyond its engine, the R received a mesh grille, model-specific bumpers and wheels, uprated brakes and adaptive damping. Identity should be checked through the VIN and factory data because ordinary cars can acquire R-style exterior parts.

Jaguar S-Type R buying guide
Engine, cooling and supercharger
Listen for timing noise and supercharger or auxiliary-drive bearing sounds. Check water pump, thermostat, radiator, hoses and expansion tank, and reject cars showing overheating evidence. Oil leaks and poor crankcase ventilation deserve investigation.
Automatic transmission and differential
The ZF six-speed should engage quickly and change smoothly under light and full throttle. Despite historic sealed-for-life claims, fluid-service evidence is desirable. Check the propshaft, mountings, differential and rear-wheel bearings for vibration or noise.
Body, suspension and electronics
Inspect sills, arches, floor edges, subframes and suspension mounts. Worn bushes, ball joints and dampers are common age-related costs. Test the electronic parking brake, climate control, instruments, navigation, seats, parking sensors and every warning message.
Why the S-Type R is becoming collectible
The R combines traditional Jaguar ambience with a modern supercharged powertrain and remains less conspicuous than many contemporary performance saloons. Good original examples are increasingly difficult to find because low values once encouraged deferred maintenance and modification.
