A milestone on the road to further efficiency increases is needs-based hybridisation. To this end, Daimler has developed a modular hybrid construction kit for cars and commercial vehicles.
All variants of the hybrid powertrain can be realised on this basis: from so-called mild hybrids to all-electric driving. Of particular importance to us is the plug-in hybrid, whose batteries can be recharged on a power outlet. Daimler is the world market leader for hybrid powertrains in the commercial vehicle sector. With the Global Hybrid Centre, FUSO makes substantial contributions at Daimler Trucks to the development of hybrid technology in the transport business.
Daimler has the most extensive and best-selling hybrid product range in the premium segment across all vehicle series. The focus is currently on plug-in hybrids for cars as well: By 2017, we will have ten such models on the market in all. The concept of the plug-in hybrid offers the best compromise between electric and conventional mobility today. The major advantage of plug-in hybrid vehicles is combining the benefits of the internal combustion engine with those of the electric motor. It helps to lower the overall fuel consumption and to enhance the performance because the electric motor substitutes or assists the internal combustion engine in situations where the internal combustion engine exhibits rather unfavourable characteristics. Furthermore, their batteries are large enough to easily meet the requirements of city motoring in all-electric mode and thus driving locally emission-free while the internal combustion engine is used for longer trips, thereby offering perfect long-distance capabilities.
With a view to the next decade, it will therefore be the blockbuster technology from our perspective.
The SuperTruck, the hybrid truck from Freightliner, is a fuel consumption champion: During road tests, the truck consumed on average about 19 litres per 100 kilometres with a total weight of 29.5 tonnes and a speed of about 100 km/h (unlike in Germany, there is no 80-km/h speed limit for trucks in the USA). Normal fuel consumption in this weight class today is about 39 litres.
With the Citaro G BlueTec Hybrid, Mercedes-Benz furthermore demonstrates how bus public transit can be made environmentally friendly and thereby sustainable. The Citaro G BlueTec Hybrid can travel up to ten kilometres on all-electric power. The bus is driven by four electric wheel hub motors whose electricity comes from one of the world's largest lithium-ion batteries in mobile use. The electricity is generated during braking and by a generator, if needed.
