It’s a fine engine with a split-personality soundtrack. It’s smooth and punchy at low speed with a gentle woole, but as the revs rise the engine note gains urgency and builds into a distant mechanical thunder as it hurls the XJ-S forward. What’s extraordinary about it is how quiet the XJ-S remains when you’re pressing on. Throw in some bends and the XJ-S grips well, the smaller Moto-Lita steering wheel on this car adding a bit of feel to steering that was criticised in period for being too light. But the Jaguar is happier sweeping through fast, open bends than being forced into tight turns.
