The Mercedes Benz S500 plug-in hybrid is the third hybrid model in the S class presented by Mercedes. The car will be launched in the market by 2014. New technology of climate control, efficiency and drive system has been seamlessly integrated in this new model. The result is that it is capable of delivering a level of performance that was thought to be impossible a few years ago.

Before this, Mercedes had already presented the S400 and the S300 BlueTEC hybrid models to the world. The former was the first car in the world which came with a standard specification hybrid drive system in 2009. The latest presentation in the series raises the standard even further. The S400 and the S300 BlueTEC had electric motors powered by batteries which can be charged during coasting or braking or by the combustion engine.

On the other hand, the S500 comes with a new high voltage lithium ion battery which can deliver ten times the power of the older models. A charging socket is located on the right side of the rear bumper. So, you can get the batteries charged from an external source as well. This powerful battery has a power output of 80 kW and delivers a maximum torque of 340 Nm. The result of these innovations is that the car can drive up to 30 kms on electric power alone. In addition to the above power delivered by the battery, the combustion engine delivers a maximum power of 245 kW and a peak torque of 480 Nm. The combined power allows the car to accelerate from 0 to 100 kmph within a mere 5.5 seconds and it has a top speed on 250 kmph. It only consumes 3 liters of fuel to cover 100 kms.

To increase the convenience, you can choose one out of four hybrid operating modes at the push of a button. These are Hybrid, E mode (electric power only), E save (battery fully charged so that you can switch to electric power later) and charge (charging battery while driving). This customization is aided by the haptic accelerator paddle. Here, a point of resistance is provided in the accelerator paddle to let you know about the activation of the combustion engine.

The anticipatory energy management system is another outstanding innovation incorporated in this model. It uses a recuperative braking system of the second generation. When you depress the brake paddle, it is the electric motor and not the disc brakes that bring about the initial deceleration. The pedal travel sensor records the brake pressure of the driver. The RBS also controls the brake pressure on the rear axle. In addition, when the vehicle is coasting, the combustion engine is switched off. the drag torque created when the vehicle is rolling is used by electric motor as recuperation torque. If you do not depress the brake pedal, there will be no additional deceleration torque provided by the vehicle to charge the battery so that the vehicle can sail. The S500 intends that the combustion engine should be used to charge the electric motor as little as possible and only when it is operating at the highest level of efficiency.

With its latest presentation, Mercedes has increased its own standards in fuel efficiency and reduction in carbon footprint. Before this, there was the S400 that used only 6.3 liters of fuel to cover 100 kms. The petrol engine of this model delivered a maximum power of 225 kW with the electric motor adding another 20 kW. In comparison, the S300 BlueTEC used a diesel engine which delivered a power of 150 kW coupled with an electric motor delivering 20 kW. It used 4.4 liters to cover 100 kms.
