The restyled first-generation Jaguar XJ refined a saloon that already set the standard for quiet, composed luxury motoring, pairing a low-slung four-door body with the smooth straight-six power Jaguar built its reputation on.
A representative Jaguar XJ engine here is the 3.4-litre petrol straight-six, offered as the 3.4 MT with a manual gearbox or the 3.4 AT with an automatic. Both send power rearward, so the drivetrain favours smooth, unhurried cruising; the automatic suits town traffic, while the manual gives keener drivers more control.
