Spy photos show the car's number plate, which, when checked against an online vehicle database, reveals that the model being tested has a 2.0-litre diesel engine and that the car has been under development since April 2016.
The car was spotted testing near Royal Leamington Spa, not far from Jaguar’s headquarters in Coventry. The photos also reveal that Jaguar Land Rover’s chief engineer, Mike Cross, behind the wheel.
Jaguar has long been rumoured to be developing a diesel variant of the F-Type, as well as a four-cylinder petrol version running an upcoming Ingenium engine. It’s expected to produce as much as 300bhp in the F-Type.
The F-Type diesel project was reported to have been shelved, but the emergence of these new images suggests it has been picked up once again, at least for evaluation purposes.
