To be unveiled later this year, the new sedan will likely feature W12, V8 and plug-in hybrid powertrain options.
The first teasers for the new Bentley Flying Spur "four-door Grand Tourer" were issued overnight.
The brief video trailer reveals the new car's retractable flying B ornament, as well as the bonnet's chrome spine, and the upper section of the grille.
Bentley has also sketched out the car's side profile. The outline and spy photos indicate the new sedan will have softer detailing than today's car.
As with the two-door cars, the Flying Spur will likely debut with the company's 467kW/900Nm 6.0-litre twin-turbo W12 engine.
In the Continental, the W12 is paired with an eight-speed dual-clutch transmission and all-wheel drive as standard.
Further into the Flying Spur's life cycle, we expect to see the Continental's 405kW/770Nm 4.0-litre twin-turbo V8 added to the range.
