There’s a simple engine line-up in the XJ, since there’s just one choice. The 3.0-litre V6 diesel has 296bhp and a whopping 516lb ft of torque. Throughout the XJ’s life, it’s been our pick of the range, so the fact that it is now the only option is no bad thing.
This unit offers decent performance and a lot of overtaking power, thanks to the masses of low-down torque. Acceleration is brisk rather than scintillating, though; the engine offers all the pace you’d need in everyday commuting and easily manages motorway schleps, but there is no longer a performance-focused halo model offering the kind of blistering speed that top-spec rival cars offer.
Those rivals have a lot more options when it comes to engines, including hybrid technology and petrol models. And while the XJ keeps up to speed with equivalent-powered diesel options, it’s a shame that there isn’t more of a choice.
An automatic gearbox is standard and smooth in most situations. It can be hesitant when pulling away from low speeds, however.
