We saw the CX-F concept recently at the Detroit Motor Show, and here's the real thing: caught out testing in northern Sweden alongside its predecessor, the S-Type. The C-XF is clearly lower-riding, as well as being a couple of inches longer and wider; it's to be marketed as more of a sports-focused rival to the 5-Series than as a luxury model. As rumoured, the production car isn't going to have quite such a radical curve to its roofline as the concept and it will have to have conventional manually operated door handles and rear-view mirrors in place of the concept's sensors and rear-view cameras. However, the styling looks otherwise little changed from that of the show car, bar slightly thicker headlights and smaller wheels (the concept sat on 21-inchers). The production car, besides having more rear headroom than the concept, will also have thicker-bolstered seats and a more conventional dashboard - without the sensor-driven controls - though some of the LED ambient lighting features could stay. The blue-glowing fibre-optic door trim detailing is unlikely to make production, however. Engines will include the familiar 420bhp 4.2 V8, but a new version of the 2.7 V6 diesel will also be offered.
