Mercedes Benz S500 Plug-in-hybrid 2014
Stuttgart July 31st 2014 -"The new S 500 PLUG-IN HYBRID offers our customers the entire range of innovations that make our new S-Class so successful, and thanks to its intelligent operating strategy ensures outstanding driving pleasure and dynamism combined with the highest efficiency. Moreover, it allows completely emission-free driving for up to 33 km," says Ola Källenius, Executive Vice-President for Sales at Mercedes-Benz Cars.
"The S 500 PLUG-IN HYBRID is the first luxury saloon with the performance of a V8 and the fuel consumption of a compact model. The greatest challenge in this is to translate highest efficiency into superior performance. In this respect there is a highly interesting parallel with our successful Formula 1 racing car, which likewise has a turbocharged V6 engine and hybrid drive," says Prof. Dr. Thomas Weber, member of the Daimler AG Executive Board responsible for corporate research and Mercedes-Benz Cars Development.

The third hybrid model of the new S-Class, the S 500 PLUG-IN HYBRID, sets new benchmarks with regard to efficiency as well as drive-system and climate comfort. With 69 g CO2 per kilometre (3 litres/100 km) the S‑Class sets a new benchmark for luxury saloons that just a few years ago was thought virtually impossible. The 80-kW electric drive with externally rechargeable battery makes emission-free driving for about 30 km possible. It is combined with the new 3.0-litre V6 turbocharged engine. Wireless charging will be the next step: one of the next steps on the way to perfect electric drive and plug-in hybrid vehicles is wireless charging. Daimler and BMW have now agreed on jointly developing and implementing one common technology.
- The S 400 HYBRID was the first in the world to feature a standard-specification hybrid drive system with lithium-ion battery in 2009. With the new S-Class Mercedes-Benz expands the hybrid line-up in this model series to three models: the S 400 HYBRID, S 300 BlueTEC HYBRID and S 500 PLUG-IN HYBRID. All second-generation hybrid drive systems share the seamless integration into the powertrain. The combustion engine can be completely decoupled from the electric motor. Further features are the second-generation recuperative braking system and the anticipatory Intelligent HYBRID energy management system.
- "With the S 500 PLUG-IN HYBRID Mercedes-Benz sets another milestone on the road to emission-free mobility on the basis of our modular hybrid matrix", explains Prof Dr Thomas Weber, responsible on the Daimler Board of Management for Group Research and Head of Mercedes-Benz Cars Product Engineering. "In this way the S-Class turns into a genuine three-litre car with generous space and superlative drive-system comfort."
- While the batteries of the S 400 HYBRID and S 300 BlueTEC HYBRID as autonomous hybrids are charged during braking or coasting or by the combustion engine, the new high-voltage lithium-ion battery of the S 500 PLUG-IN HYBRID has ten times the energy content and offers the option of being recharged from an external source with a charging socket located on the right side of the rear bumper. With the help of the electric synchronous motor (80 kW/340 Nm) the S-Class can thus drive for up to around 30 kilometres on electric power alone.
Four hybrid operating modes can be selected at the push of a button:
- E-MODE: electric power only
- E-SAVE: fully charged battery is reserved to be able
to drive on electric power alone later
- CHARGE: battery is charged while driving
- Under the conditions specified by the certification rules the S-Class as a full hybrid generates 69 g CO2 per kilometre. With consumption equivalent to 3 litres per 100 kilometres the S-Class sets a new benchmark for luxury saloons that just a few years ago was thought virtually impossible. It delivers these top values without restrictions in power, passenger comfort or operating range and offers a high level of climate comfort thanks to the pre-entry climate control functions.
The most important benchmark data of the S 500 PLUG-IN HYBRID:
- Power output of 245 kW of the combustion engine plus 80-kW electric motor and torque of 480 Nm of the combustion engine plus 340 Nm
of the electric motor
- Overall consumption (NEDC) 69 g CO2/km (3.0 l/100 km)
- Operating range on electric power alone about 30 km
- Top speed 250 km/h, 0-100 km/h in 5.5 sec.
- Intelligent HYBRID: anticipatory energy management system with optimal use of recuperation during deceleration
- Individualisation possible as the result of the combination of the transmission modes with the four hybrid operating modes – HYBRID, E‑MODE, E-SAVE and CHARGE.
- Haptic accelerator pedal for superior vehicle control: A point of resistance on the accelerator pedal provides feedback about the activation of the combustion engine and helps in metering the power output.
- Fast external charging of the high-voltage traction battery
- Pre-entry climate control of the interior
- Intelligent HYBRID: anticipatory energy management system
The second-generation S-Class hybrids feature an anticipatory energy management system and thereby improve energy efficiency. The operating strategy of the hybrid drive system not only accounts for the current driving condition and driver input, but also adjusts to the likely route (inclines, downhill stretches, bends or speed limits) for the next eight kilometres. Intelligent HYBRID uses the navigation data from COMAND Online to manage the charging and discharging of the high-voltage battery. The goal is, for example, to use the energy content of the battery for propulsion ahead of a downhill stretch in order to recharge it while going downhill using recuperation.
Recuperative braking system: the electric motor as alternator
The largest potential for lowering the energy consumption of hybrid drive systems lies in maximising energy recovery during coasting and braking.
Upon depressing the brake pedal the deceleration is initially effected by the electric motor and not by the disc brakes. The new S-Class is the first to use a recuperative braking system (RBS) of the second generation. It ensures an unnoticeable overlapping of the conventional mechanical brakes and the electric braking performance of the electric motor in alternator mode.
The driver's desired braking power is recorded by a pedal-travel sensor.
The deceleration is dependent on the driving condition and is split into a recuperative brake-force portion and a portion to be supplied by the wheel brakes. The brake pressure on the rear axle is controlled by the RBS dependent on the current recuperation potential of the powertrain.
In addition, the combustion engine is switched off any time the vehicle is coasting and its drag torque when rolling is used by the electric motor as recuperation torque. However, without depressing the brake pedal no additional deceleration torque is provided for charging the battery and the vehicle can "sail". The combustion engine is to be used for charging the battery as little as possible and only at suitable and most efficient operating points.
Hybrid pioneer in the luxury segment
The world's first standard-specification hybrid drive with lithium-ion battery debuted at Mercedes-Benz as early as 2009: the S 400 HYBRID was the most fuel-efficient petrol-powered luxury saloon for a long time. And the most successful hybrid in its segment: some 20,000 buyers worldwide opted for
the S 400 HYBRID.
With the new S-Class Mercedes-Benz now continues its comprehensive hybrid offensive. In the S 400 HYBRID and S 300 BlueTEC HYBRID there are already two hybrids of the new S-Class to choose from:
- The new S 400 HYBRID burns just 6.3 litres of fuel per 100 kilometres in the NEDC cycle (combined). This represents a reduction by 20 per cent over the predecessor. CO2 emissions of 147 grams per kilometre also represent a new record in this vehicle segment. These exemplary figures go hand in hand with outstanding performance potential: the petrol engine develops 225 kW (306 hp), while the electric motor adds another 20 kW (27 hp). The torque of the combustion engine is 370 Nm plus 250 Nm from the electric motor.
- In the S 300 BlueTEC HYBRID Mercedes-Benz has combined the 2.2‑litre four-cylinder diesel engine developing 150 kW (204 hp) with the powerful hybrid module developing 20 kW (27 hp). The peak
torque of 500 Nm produced by the combustion engine is overlaid
by the 250 Nm of peak torque produced by the electric motor.
The S 300 BlueTEC HYBRID makes do with 4.4 litres per 100 km in the combined cycle (CO2: 115 g/km) and complies with the criteria for energy efficiency class A+. Consequently Mercedes-Benz has, over the course of ten years, nearly cut fuel consumption in the 150-kW performance class by half.

Wireless charging of electric drive and plug-in hybrid vehicles : PLUG IN HYBRID - unplugged
 |
One of the next steps on the way to perfect electric drive and plug-in hybrid vehicles is wireless charging. Daimler and BMW have now agreed on jointly developing and implementing one common technology.
Wireless charging of the battery will make the handling of electric drive and plug-in hybrid vehicles even easier. Mercedes-Benz will commence fleet testing of this “unplugged” technology with the S 500 Plug in HYBRID soon, in order to develop a real S-Class solution in recharging the high voltage battery in terms of comfort and ease of operating in the near future.
The system consists of two components: a secondary coil integrated into the under tray of the car and a primary coil integrated into a floor plate that can be placed on a garage floor for instance. Electrical energy is transmitted contact-free without the need for a cable, at a power rate of 3.6 kW and with a degree of efficiency of 90%. Daimler and BMW have agreed on jointly developing and implementing one common technology for wireless recharging high-voltage batteries of electric drive and plug-in hybrid vehicles.
In September 2014, the Mercedes-Benz S 500 PLUG IN HYBRID will be launched. It offers 325 kW of power and 650 Nm of torque, sprints in only 5.2 seconds from zero to 100 kph, and can go 33 km on electric power alone. It has certified fuel consumption of 2.8 litres for 100 kilometres, equalling 65g CO2/km. And it achieves excellent efficiency in real word driving as well. Key elements for this stunning performance are a bi-turbo V6 and a highly sophisticated hybrid powertrain.
The S 500 PLUG IN HYBRID is the first luxury sedan with a certified consumption below three litres per 100 km and another milestone on the way to emission-free mobility. After S 400 HYBRID and S 300 BlueTEC HYBRID, it is the third hybrid model in the S-Class range. It combines a highly advanced hybrid powertrain with the unique innovations and comfort features of the S-Class.
