Our spy photographers were hanging around Jaguar’s test center near the Nurburgring when in the midst of all the XFR models driving around, they came across the vehicle seen in these spy shots. This may look like a standard XFR, but upon closer inspection, we think this is actually a test mule for the XFR-S model previously confirmed by Jaguar’s Global Brand Director, Adrian Hallmark.
This test mule may be missing some special body parts to distinguish it as the XFR-S, but its track looks a bit wider and it is already sporting the wheels found on the XKR-S . Our proof, however, is in the pudding and that’s the sound escaping from the exhaust. The test mule is currently being tested with the XKR-S Convertible prototype and the sounds the car is emitting are nowhere near the standard XFR’s at the same test center. The throttle response on this test mule is also very quick when the driver floors it, which can only be explained by the presence of the future XFR-S model’s 550 HP engine borrowed from the XKR-S.
