Hoping to persuade police forces across the UK that the XJ-S could be a high-speed response vehicle, a single demonstrator was developed. It’s fresh out of restoration and we’ve driven it.
Although Jaguar had stopped offering the XJ-S with a manual gearbox in 1978, two were produced in the early Eighties which also had the Lucas P-Digital injection. We’ve tracked down what’s thought to be the sole survivor.
Despite coming from two different manufacturers, by sharing much below the surface, the DB7 and Jaguar XJS are closely related. We compare a straight six-engined example of each to discover which of these surprising siblings we prefer.
