We’re mere weeks away from the unveiling of the new W213 Mercedes-Benz E-Class on January 11, and to whet our appetites still further, Stuttgart has released a new video documenting the development of the next-generation executive sedan.

The film lists the mind-numbing statistics the latest E-Class has achieved over its four-year development cycle. For instance, Mercedes has built 1,200 prototypes (covered in 3,200 square metres of camouflage, no less), collectively amassing a mileage of over 12 million kilometres across four continents – in extreme conditions of between -32 and a sweltering 60 degrees Celsius.

The vast amount of technology onboard has also been thoroughly tested. In total, 10,000 autonomous braking tests have been conducted, along with 5,000 autonomous lane changes on the new Active Lane Change Assist – and we bet our bottom dollar that the video barely scratches the surface in terms of the sheer depth of engineering put to the test.

E-Class Interior

Mercedes-Benz has already revealed the interior of the next-generation E-Class, showing the S-Class-inspired dashboard, twin 12.3-inch displays on higher-end models, new digital instrument cluster and COMAND Online display graphics, steering wheel-mounted touch pads to control the infotainment system as well as an impressive new 23-speaker Burmeister sound system.

The company has also spoken volumes about the technologies that will make its way into the E-Class, including an updated version of the Multibeam adaptive LED headlight technology that debuted on the facelifted CLS; diode count has been raised from 24 to 84. Smartphone integration has also been expanded – your phone can now serve as a key, as well as guide the car in and out of parallel and perpendicular parking spaces via the Remote Parking Pilot function.

Safety technologies like Active Brake Assist also get a bump up, capable of scanning other lanes for cars and initiating braking earlier if it senses an evasive manoeuvre is impossible. Other features include the new Evasive Steering Assist, Distance Pilot Distronic with Speed Limit Pilot and Active Lane Keeping Assist, as well as an uprated Pre-Safe system – the latter now protects your ears in a crash, and pushes you closer to the centre of the car to provide more survival space in the event of a side impact.
