The next-generation Bentley Flying Spur has again been spotted by our spies prior to its reveal. While the prototype seen here sports much the same camouflage as before, we can get some idea of the design of the new luxury sedan, now that its coupé sibling – the latest Continental GT – has been out for some time.

And as the two-door model has become more svelte and less brutish, so has the Flying Spur, something that is readily apparent in spite of the amount of camouflage added on top. The longer dash-to-axle ratio – which on the Conti GT was accomplished by moving the engine behind the front axle – really helps in giving the car lankier, more relaxed proportions, emphasised by the sleeker roofline.

Aside from that, it’s still hard to judge the styling of the new car, aside from the continued presence of a large rectangular front grille, the “power line” along the side, prominent rear haunches and twin oval exhausts. The head- and tail lights have been covered from view (expect the latter to go to a single oval shape like the Conti GT), but the wide front air intake with moustache-like inserts appears to have been retained.

Underneath, the Flying Spur will move to Volkswagen’s modular MSB platform for rear-biased front-engined cars, which is also shared with the Porsche Panamera. Engines will likely include a 4.0 litre twin-turbo V8 from the Panamera Turbo, along with Bentley’s renown 6.0 litre twin-turbo W12, which in the Conti GT has been outfitted with direct injection and now produces 626 hp and a heady 900 Nm of torque.

A plug-in hybrid version is also expected – it has already been seen undergoing testing since last year. The hardware will likely be shared with the Panamera Turbo S E-Hybrid, which pairs the 550 hp 4.0 litre V8 with a 136 hp electric motor to produce a whopping total system output of 680 hp and 850 Nm. All models should get an eight-speed dual-clutch transmission from the Conti GT.
