The Jaguar XJ carries a heavy burden as the sole British vehicle in a German-dominated market, but it does so admirably.

A 470-hp turbocharged V-8 is also offered, but a 3.0-liter turbocharged V-6 with 340 horsepower is standard.

The XJ has quick steering that may be a touch too sharp for consumers of large luxury sedans, giving it a distinctly aggressive driving style.

With high-quality materials and opulent style, the interior is properly posh for the XJ's position at the top of the Jaguar series.

There are both normal and long-wheelbase variants available, with the latter providing a significantly comfier rear seat.

With its roaring power and five-star interior fittings, the Jaguar XJ is still the outlandish favorite among big luxury sedans.

If such behavior doesn't seem out of step with this car's refined exterior, the turbocharged V-6 and V-8 motors give the XJ tire-squealing speed.

The new XJR575 model, which is launched to the line at the top and acts as the most potent XJ, is reviewed separately.

The 3.0 liter, 340-horsepower supercharged V-6 is the XJ's base engine; a 5.0 liter, 470-horsepower V-8 is also an option.

But don't disregard the V-6. This engine is incredibly powerful when a burst of acceleration is required, but it lacks the sheer grunt and sonic drama of the V-8.

The 8.0-inch infotainment interface from the outgoing Jaguar XJ's successor has been replaced with a 10.2-inch screen inside the 2018 model.

The XJ's agility is one story twist. Its general agility makes it feel, when pushed strongly, like a vastly smaller sports sedan.
