The G30 BMW 5 Series as well as the G11 BMW 7 Series have been undergoing winter testing ahead of their respective unveilings sometime in the next two years, and our European spies have managed to capture video footage of the two Munich bruisers in the snow.

We’ll start with the 5 Series, which is expected to go on sale in the summer of next year, with the GT preceding it in the spring. Heavily clad in disguise, very little of the G30 can be so far, but it will almost certainly feature an evolution of BMW’s current design language, including headlights that flow into the large kidney grilles, as well as a new shape for the door mirrors.

The G11 7er, set to be unveiled at the Frankfurt Motor Show in September, is clearly closer to production, with less camouflage and more production-ready head- and tail lights and exhaust outlets. No surprises regarding the design here, as images of an undisguised car were leaked on New Year’s Day, so we already know more or less what it looks like.

Both cars (as well as the next 3 and 6 Series) will be based on BMW’s new modular rear-wheel drive “35up” platform, now known as CLAR (shorthand for Cluster Architecture). The system utilises fewer but more versatile subassemblies for greater flexibility – for example, smaller-engined 5 Series models will use 3 Series suspension, while six- and eight-cylinder variants get a 7 Series setup.

The new architecture will combine the use of steel with lightweight materials such as carbon fibre, aluminium and magnesium, shaving as much as 80 kg off the 5er’s weight (and up to 170 kg off the 7er). The next M5 will take it to the absolute extreme, shedding a massive 180 kg.

Slotted into the engine bay are BMW’s new B family of modular turbocharged engines – the 1.5 litre three-cylinder B38 (petrol) and B37 (diesel), the 2.0 litre four-cylinder B48 (petrol) and B47 (diesel) and an upcoming 3.0 litre six-cylinder B58 (petrol) and B57 (diesel). The B47 has already made its way into the current F10 520d, making 190 hp and 400 Nm.

There should also be a new plug-in hybrid eDrive model that uses the recently unveiled X5 xDrive40e‘s 313 hp/450 Nm drivetrain (will it be called a 540e, then?), while a new M550d is set to utilise no less than four turbos to develop as much as 400 hp. V8 engines are expected to be dropped from the cooking 5 Series, with only the M5 receiving a revised version of the current 4.4 litre unit, developing upwards of 600 hp.
