A car is a piece of equipment you can not live without. It is essential to travel the many daily journeys. The car comes in many models to better meet the needs and requirements of each. If the models are distinguished by their paces, there is also a difference in weight.
The average weight of a car is around 1,500 kilos (1.5 tons). The heaviest car ever known is the Mercedes Benz W150 770 that was produced between the years 1938 and 1943 and weighs 3,400 kilograms. On the lighter side or a car, the Piaggio MP3 LT 250ie and the Piaggio MP3 LT 300ie (2010) compete for first place with a weight of 224 kilos .
Namely: a car that is too heavy can lose agility, stability and performance. In addition, braking distances become longer and fuel consumption is higher. Different cars have different weighs. Nevertheless, the some cars have heavy weigh and equipments of a heavier car is generally richer and the finish is more accomplished.
Our cars had grown enormously for 20 years. A trend that fortunately is reversing today!
By car, weight is the enemy! The weight has all the disadvantages: handling less stable, and less agile, elongated braking distances, reduced performance, increased consumption. And, ultimately, need to resort to larger and more greedy engines to counter the overweight. And yet, for more than 20 years, the manufacturers have weighed heavily on their cars. Just for “good” reasons: richer equipment; a nicer finish, more soundproofing. And, especially, increased safety, in case of shock: all that is reinforcements, to get a more resistant cabin, structures instead deformable for the shock absorption areas, it’s more weight.

Compare a Peugeot 205 from 1983: 740 kg. The 207 born 23 years later: 1,150 to 1,280 kg! All these extra pounds increase fuel consumption. But the trend today is reversed. It was BMW that started in the late 90s, thanks to aluminum suspensions, and magnesium in the structure of some engines (6 cylinders). Mazda for 5 years with the small Mazda 2, has lightened its construction. Peugeot with the new 208: depending on the versions, from 110 to 170 kg of earned!
Builders are back to the wall, with future pollution standards: you must lose weight, by all means! For example, you will see the generalization of three-cylinder engines instead of four on small cars: a weight gain of at least 20 kg!
Aluminum is spreading more and more. As for the ultra-light materials carbon fiber, Kevlar, they are excellent in weight. But ultra-expensive.
The “Autolab” electric car service in USA is struggling to become profitable
It is rumored that the 15,000 subscribers claimed are in fact only 5,200 to actually have a subscription to the year.
While the exploitation of these self-service electric cars could reach its economic balance only from 80,000 subscribers. The question: Will this service be profitable as planned in 2019?
The electronic PV will expand
It appeared late last year. It will become widespread in all cities from this summer.
The agent sets the PVs on a touch-sensitive computer tablet. Once back at the police station, he transfers the data from the PVs prepared on a computer.
You, motorists, you find more, under the wiper, only a butterfly warning you that a PV has been drawn up.
