Jaguar is preparing a heavily revised F-Type for release next year, and our spy photographers have images of both the coupe and the convertible running tests around the Nurburgring Nordschleife. The underlying architecture remains as before, however its external bodywork will receive a rather thorough revamp.

The sharp end brings a new headlamp design that supersedes the current, upright orientation, and will become more in line with the slimmer horizontal look shared across the Jaguar range, such as that seen on the facelifted XE and the second-generation XF.

The central grille remains largely as before, though concealment around the side intakes indicate likely changes to the area. Its bonnet continues to feature longitudinal crease lines, though it remains to be seen if these will be identical to those on the pre-update car.

Front-end treatment applied to the coupe appears identical on the convertible, with the coupe’s glasshouse and roofline appearing to be carried over from the present car, along with the upswept kink towards the C-pillar. The convertible appears to sport a rear spoiler that is wider and stretches the full width of its bootlid, while the item on the coupe is longer but narrower, also apparently made to fit the width of its rear hatch.

The rear end has also received updates to the tail lights, now featuring a broader curved arc more akin to the design on the XE sedan’s tail lights, while the rear bumper appears to have gained additional aero elements in the centre diffuser area; the quad exhaust pipes seen on both examples here likely denote the higher-end V8 variants.

The bent-eight powerplant for this forthcoming F-Type update has been rumoured to come from BMW, our sources say, likely replacing the current supercharged 5.0 litre V8 for emissions compliance – if that does get pressed into service. though Autocar expects the long-serving, large displacemet engine to carry on in the F-Type alongside the turbocharged four-pot and the recently introduced Ingenium straight-six unit, which employs turbocharging and electric supercharging.
