The Mercedes and the mobility of tomorrow – al volante

SEVEN BILLION FOR THE GREEN – 14.5 billion Euros of investments in research, of which more than half for the “green” mobility: This is the message of Thomas Weber, board member administration of Mercedes , made during an event dedicated to the technologies of tomorrow, and in particular those involving electric mobility. On this occasion we were also shown many technologies ready to go into business, pointing to reducing emissions.

HYDROGEN? YES, BUT PLUG-IN – In the coming years will be a dozen electric models that will be put into production by Mercedes. First, the new generation of electric Smart ( in the picture below ) that, for the first time with this tension, will also offer four doors, and then take the Mercedes GLC hydrogen ( in the photo above ). Which, unlike the car fuel cells sold so far, will also have a rechargeable battery from the socket that should ensure alone fifty kilometers of autonomy (after the current is produced by reacting the hydrogen with the oxygen of the ‘ air in fuel cells: according to Mercedes so you can follow another 450 kilometers). At the Paris Motor Show in October, however, it will be unveiled a large luxury car that will debut a new platform for all-electric vehicles, characterized by two motors (one per axle, in order to have a four-wheel drive) and Li-Ion lithium located under the floor; the details have not been disclosed, but there is already talk of autonomy around 500 kilometers on one charge.

THE BACK ARE IN LINE – At the event there was also talk of the traditional combustion engines, starting with the two-liter diesel which just debuted on the E-Class is the first in a family of modular engines that will expand soon with the introduction of a four-cylinder petrol and a in-line six-cylinder ( pictured below in a partial view) which will gradually replace the current V6 (architecture that will also be abandoned for diesel). The design of the return of engines with six adjacent pistons is explained by the Mercedes technicians: although longer than a V6, this kind of engine allows to obtain more space to mount side of the complex (and cumbersome) filters which, to be efficient, must be as close as possible to the exhaust manifolds. This aspect will be increasingly important, also for petrol engines is no accident, Mercedes has announced that the next generations of engines to “green” will mount the particle filters similar to those mounted by years in diesel, to fall in future anti-pollution standards. In addition, the architecture in-line six-cylinder allows you to share more parts with four-piston engines and have assembly operations faster and more standardized.

PARTICLE FOR PETROL ENGINES – The new six-cylinder in-line petrol engine will debut in the S-Class in 2017, on the occasion of the restyling . It will not be the only new: will be paired with one of the two micro-hybrid systems presented on the same occasion. Both utilize a second battery to 48 volts (and therefore able to store and deliver more energy than traditional ones) and an electric motor that charging in slowdowns giving a hand to that heat in the accelerations. If the first system, simpler and designed for four-cylinder engines, the alternator takes place and is connected to the engine with a belt, the second is positioned between the flywheel and transmission ( in the photo above ): works on the same principle but is more efficient.

WIRELESS CHARGING FROM 2017 – With the update of next year, the S-Class will also debut the system Wireless charging for its plug-in hybrid version ( in the photo above ). In practice, it is a plate to be fixed to the floor which, when parking the car above, transmits energy in the form of electromagnetic waves: just as happens with electric toothbrushes. At present, the device has an efficiency of 90%, while with the classic cable you get to 93%. In addition, on the ground plate are present of the sensors: if a metal object or a living being touches the surface, the process stops for safety. with new batteries manufactured directly by Mercedes for the new rechargeable hybrid S, a “full” power will be enough to walk about 50 kilometers (today the house declares 30).
