2016 BMW 7-Series Tech Secrets Revealed: Video

BMW’s all-new, sixth-generation 7-Series flagship sedan is almost here, with the reveal scheduled to take place this summer before an official world debut at the 2015 Frankfurt Auto Show in September. Today, however, we have an early look at many of the technological elements that will feature in the new car, including lightweight multi-material construction, new modular engines, a new gesture control interface and even some autonomous driving features.

The most radical change being made to the 7-Series line of cars with this new model is the construction methods and materials being used. The new 7-Series has been designed around a modular platform code-named the 35up. This platform will form the basis of most of BMW’s models going forward and includes carbon fiber-reinforced plastic (CFRP) in its construction.

Using lessons learned in developing the i3 electric car, BMW engineers designed the passenger cell of the new 7-Series to incorporate CFRP in areas exposed to heavy loads. The strength of this lightweight material helps to increase torsional rigidity, meaning less traditional materials such as heavy steel needs to be used. This leads to a significant weight reduction—286 pounds in the case of the new 7-Series—which in turn leads to improved dynamics and fuel economy.

Further fuel economy gains will be brought about by new engines. The new engines are based on a six-cylinder design derived from the modular design used for BMW’s existing three- and four-cylinder engines. The engines will feature direct fuel injection as well as turbocharging, and will be paired with an eight-speed automatic transmission. We should also see this six-cylinder design used in in a plug-in hybrid version of the new 7-Series. In addition to the new six-cylinder engines, look for V-8 and even V-12 options to continue. Some markets will also receive a four-cylinder option.

When it comes to handling, the new 7-Series will benefit from some advanced chassis control systems that can be adjusted at the push of a button. These include adjustable dampers (Dynamic Damper Control), speed-sensitive steering (Active Steering) and active roll stabilization (Dynamic Drive). On top of this, the new 7-Series will come with air suspension with automatic self-leveling as standard.
