Omitting more less-known competitors, the company Mercedes-Benz releases its first hybrid model, but for the fact that the flagship - S 400 BlueHYBRID. Novelty has not yet appeared on the roads, but it happens only in the summer of 2009, has already become the most cost-class sedans in the world. The average fuel consumption of the car is 7.9 liters per 100 km, while emissions of CO2 - just 190 g / km.
Under the hood of Mercedes-Benz S 400 BlueHYBRID a gasoline engine working volume 3.5 liter, 279 hp power, and electric power of 20 hp, with starting torque 160 Nm. Thus, the total power is 299 hp, the aggregate nominal torque is 385 Nm. In addition, S 400 BlueHYBRID is the first production model equipped with a particularly powerful lithium-ion battery, which was specially designed for use in automobiles.
New Mercedes-Benz S 400 BlueHYBRID is created on the base model S 350 and is equipped with a deep drive and upgraded transmission. These include advanced V6 petrol engine with a working volume of 3.5 liters, an additional electric motor with excitation from permanent magnets, seven Automatic 7G-TRONIC, optimized for work with a hybrid module, the necessary power and control electronic devices, transformers, and high-voltage lithium-ion battery.
The compact hybrid module is Mercedes-Benz S 400 BlueHYBRID is an electric disc format, serving as starter and generator. Such a system has a dual effect: on the one hand, it helps reduce fuel consumption, and with another - significantly enhances driving pleasure. The main credit for this - the so-called additional effect by which the electric motor has an internal combustion engine strong support in the phase of the crackdown, which is a great fuel, creating an additional 160 Nm of torque. From the successful interaction of the two power units to win remains the driver - thanks to the impressive features of the torque and excellent acceleration.
In addition, the hybrid module is Mercedes-Benz S 400 BlueHYBRID has a convenient feature «start-stop», which turns off the engine when the vehicle stops, for example, before the traffic lights. When you need to renew the motion, the electric motor almost imperceptibly, and very comfortable once again starts the main power unit. And it also contributes to fuel savings and environmental protection: because the engine starts almost immediately with the first ignition, the emissions at the time of launch minimized.
When slowing Mercedes-Benz S 400 BlueHYBRID the electric motor works as a generator, and thanks to the so-called recovery of braking energy, allows the return of spent energy. In doing so, the electric motor, responsive to interacting with the engine brake and classic wheel brake mechanisms, increasing their efficiency by providing invisible, seamless transition of one phase to another. Accruing energy is stored in a powerful but compact lithium-ion battery, which is located in the engine compartment and used as needed. Managing such a complex system being highly electronic control unit, which is also installed near the engine.
