In the new videos the 5 Series's LED lighting has been blurred out. However, an earlier video, shown below, BMW did offer a glimpse of the car's tail-light design.
The lights have a similar design to those of the latest 3 Series, although they’re housed within a body that looks slightly more muscular than that of its smaller sibling.
Earlier spy shots of the 2017 5 Series have shown what the model will look like in saloon and estate guises. The exterior of both bodystyles, while undoubtedly evolutionary, give the 5 Series a more aggressive demeanour.
We know from our recent drive in a 2017 5 Series prototype in 530d xDrive form (pictured below) that the model is slightly larger than the outgoing car. The increases in length, width and height are small and aimed at increasing rear seat accommodation.
The new car will share its body structure with the 7 Series. The structure is known internally as CLAR - 'cluster architecture' - and uses more aluminium for its floorpan and bulkheads than the skeleton of the outgoing F10 5 Series. There’s also more use of aluminium for castings, helping to trim weight by as much as 100kg, despite the growth in size.
Powering the new model will be a familiar choice of turbocharged four and six-cylinder engines, with a new plug-in petrol-electric powertrain joining the ranks.
Lower-powered cars will use BMW’s latest B47 diesel and B48 petrol four-cylinder units - all in 2.0-litre form, like today’s F10 model.
BMW’s new B57 diesel and B58 petrol six-cylinder engines will offer more power. These units use a standardised 500cc individual cylinder capacity for an overall volume of 3.0 litres. One of the diesels will gain an additional electrically-driven turbo to improve low-down grunt, upping peak output towards 390bhp.
The most potent non-M model will have a newly upgraded 444bhp 4.4-litre V8 petrol engine, first seen in the 750i.
The new 5 Series will also inherit hybrid technology from the 330e, 740e and X5 xDrive40e. The hybrid system is made up of a 2.0-litre four-cylinder petrol engine with an electric motor mounted in the gearbox and a lithium ion battery located in the boot floor. The system can run in full-electric model for more than 20 miles.
The M5 model will use an updated version of the current car’s 4.4-litre V8 with a likely power output of more than 560bhp.
The new 5 Series will go on sale next year. Its rivals will continue to be the Mercedes-Benz E-Class, Audi A6 and Jaguar XF.
