Following the C 350 e* (saloon, estate and long-wheelbase version for the Chinese market), GLE 500 e 4MATIC*, GLC 350 e 4MATIC*, GLC 350 e 4MATIC Coupé * and E 350 e*, the new S 560 e* (*combined fuel consumption: 3.3 - 2.1 l/100 km, combined CO2 emissions: 78 - 48 g/km, weighted power consumption: 16.7 – 11.0 kWh/100 km) succeeds the S 500 e to become the eighth plug-in model to be launched by Mercedes-Benz. In efforts to underline the important role of hybrids in the process of electrifying the vehicles, the Mercedes-Benz plug-in models will, in future, feature the EQ Power technology badge. In addition, the Citaro hybrid sees Mercedes-Benz opening a new chapter in drive systems for city buses.
Plug-in hybrids represent a key technology on the road to a locally emission-free future of vehicles. This is because they offer customers the best of both worlds; in the city they can drive in fully electric mode, while on long journeys they benefit from the combustion engine's range. Hybridisation also makes the internal combustion engine more efficient and ensures a more dynamic performance.
Because the strengths of plug-in hybrids come to the fore in larger vehicles and on mixed route profiles, Mercedes-Benz is opting for this powertrain concept from the C-Class upwards. The strategic hybrid initiative is decisively facilitated by Mercedes-Benz's intelligent, modular hybrid concept: with its scalable structure it can be transferred to a large number of model series and body styles as well as left and right-hand-drive variants.
The new GLC F-CELL presented at the IAA as a preproduction model is also a plug-in hybrid, in which innovative fuel cell and battery technologies have been combined for the first time. With 4.4 kg of hydrogen on board, this GLC produces sufficient energy for a range of up to 437 km as part of NEDC (measured in the presence of TÜV). F-CELL drivers will also benefit from a range of up to 49 km as part of NEDC thanks to the large lithium-ion battery. For further details about the GLC F-CELL please refer to the separate section in this press kit.
The latest generation of plug-in hybrid: the S 560 e
The S 560 e boasts a fully electric range of around 50 kilometres. A crucial factor here is that, although the battery size remains unchanged, the new lithium-ion battery has an increased rated capacity of 13.5 kWh. Developed together with Bosch as part of the EM-motive joint venture, the electric motor was specially designed for the 9G-TRONIC plug-in hybrid transmission. The new, significantly enhanced power electronics have allowed further increases in output and torque. The hybrid drive system in the S 560 e combines the 270 kW (367 hp) of the V6 petrol engine with an electric output of 90 kW. In conjunction with the Mercedes-Benz Wallbox, the on-board 7.2-kW charger charges the battery quickly.
The S 560 e provides comprehensive support to promote anticipatory and economical driving: the driver is prompted when it is appropriate to release the accelerator, e.g. because the S-Class is approaching a speed limit, and assisted by innovative functions such as coasting and recuperation. For this purpose, navigation data, traffic sign recognition and information from the intelligent safety assistants (radar and stereo camera) are linked and processed.
Featuring Formula 1 technology: Mercedes-AMG Project ONE
The Mercedes-AMG Project ONE has had its world première at the International Motor Show (IAA) in Frankfurt: this two-seater supersports show car transfers the very latest and most efficient Formula 1 hybrid technology almost one-to-one from the racetrack to the road for the first time, thus delivering the highlight of AMG's 50th anniversary celebrations. It is anticipated that this high-performance hybrid will produce over 1000 hp and reach top speeds beyond 350 km/h.
The overall responsibility for the implementation of Project ONE lies with Mercedes-AMG. The complex development work was carried out in close cooperation with the Formula 1 experts at Mercedes AMG High Performance Powertrains in Brixworth and the Mercedes-AMG Petronas Motorsport team in Brackley. Together with the four-door Mercedes-AMG GT Concept, the Mercedes-AMG Project ONE provides another insight into the future of the performance-hybrid drive strategy at the sports car brand within Mercedes-Benz.
Enthusiastic: customers testing hybrid vehicles in day-to-day operation
In 2015, with a detailed customer survey, the Customer Research Center at Mercedes-Benz established what expectations drivers of luxury cars have of hybrid vehicles, and how they assess them in day-to-day operation. 25 customers covering an average annual mileage of 30,000 kilometres were given the opportunity to drive a Mercedes-Benz S 500 e in day-to-day use for two weeks. Just under half of these customers had already experienced hybrid models during a test drive or short-term rental, but none of the test subjects, with an average age of 53 years, had any prolonged, day-to-day driving experience with these vehicle types.
Three interviews were conducted with each of the participants in the study - before vehicle handover, after one week of use and when returning the test car. This enabled staff at the Customer Research Center to evaluate acceptance of plug-in hybrids over a period of time and depending on use.
These are the major results of the study:
- The level of satisfaction with fully electric driving is high (in every type and mode of operation) and even tends to increase as a result of day-to-day use.
- The acceptance of controls and displays specific to plug-in models is very high.
- The haptic accelerator pedal is highly appreciated in day-to-day driving.
- The electric operating range is an important purchase criterion, but after their day-to-day driving experience the participants in the study wished for less range than before.
- There is time available for charging in customers' daily routine: after a journey, the car is usually parked in a garage, multi-level car park or public car park for two to four hours.
- Mercedes me connect is very well received, and the enthusiasm only increases with actual use. The most used functions are the charge indicator, preconditioning and charge status.
Hybrid technology for urban buses: the Citaro hybrid
The Citaro hybrid sees Mercedes-Benz opening a new chapter in drive systems for city buses. In a global first, hybrid technology is not used here in stand-alone models, but is available as an optional extra for a surprisingly wide range of city buses with diesel and gas engines. Numerous models are thus able to benefit from the advantages: in conjunction with the likewise new electrohydraulic steering system, the Citaro hybrid reduces the fuel consumption of the Citaro, already renowned for its efficiency, by as much as a further 8.5 percent, depending on type of usage and specification.
Thanks to the intelligent combination of existing components from within Daimler Group, the Citaro hybrid offers numerous benefits: it is extremely efficient, light in weight, cost-efficiently priced and unproblematic for both drivers and workshops. The technology in the new Citaro hybrid is not a transitional solution that will ultimately be replaced by a fully electric drive system, but one that allows Mercedes-Benz to hone the combustion engine in a unique way to maximise efficiency. The city bus is the first commercial vehicle to feature a separate 48 V on-board electrical system.
