The all-new BMW 5-Series has been spotted testing again. New platform and lightweight materials are confirmed for 2017 executive sedan together with design cues lifted from the upcoming 7-Series.
BMW’s all-new 5-Series is one of its most technically advanced cars yet and a crucial model for the firm. Its sophisticated platform, known under the internal codename OKL or Oberklasse – the German therm for ‘luxury class’, has been conceived to underpin all high-end BMW models that use a longitudinally mounted engine, including future 7 and 6-Series models.
The structure of the new BMW 5-Series uses a combination of aluminium, hot-formed high-strength steel and composite carbonfibre parts to reduce weight and deliver exceptional rigidity levels. CFRP technology will be used not only for structural purposes but also for key body parts such as roof, hood, boot lid and doors. This solution will help bringing down the model’s weight, in comparison to the ongoing generation.
The new BMW 5-Series is planned to feature a family of six, eight and twelve-cylinder engines with a plug-in hybrid variant also available right from the outset. The hybrid will mix a gasoline engine with an electric unit, being positioned as a direct rival for the upcoming Mercedes E-Class Plug-In Hybrid. The in-line units are central to the new modular engine family, with both petrol and diesel units set to share common capacities.
BMW is planning to provide the new 5-Series with a new ZF-engineered nine-speed automatic transmission and a draft of innovative systems such as traffic warning, self-parking or autonomous driving capability.
