On an average city car, the tank holds around 40 liters, as much weight as you drag with you. This mass disappears on an electric car where it is replaced by a much heavier battery pack. With a flaw in the key: this weight does not reduce as you roll, unlike the gasoline consumed ...

According to British startup Page-Roberts , it's easy to improve on this without reducing the number of battery cells but changing the battery layout. Like an aquarium jar, we would be arranged around a central “mast” instead of the palm tree of your goldfish.

Less high, more aerodynamic. Usually located under the car, on the floor, the battery pack should, according to these engineers, be positioned in the center of the vehicle, upright, as shown in these transparent representations. This would significantly improve the aerodynamics of the car by gaining a third of range on average.

According to their simulations, an electric 4-seater city car with a maximum range of 300 km could almost reach 600 km.

The battery race is over. Their explanation lies in the fact that the current classic design called "skateboard" (an electrified board on which we add the passenger compartment) tends to enhance the cars and brakes them. The British say they can “  dramatically increase the efficiency of electric vehicles with advanced engineering solutions that deliver design elegance.  ”An idea that would stop the race for super-batteries, greedy in manufacture, but will force all manufacturers to rethink their models and interior design (who wants to travel back to back?). However, nothing prevents designing the next generation of cars on this basis, and in particular autonomous vehicles ...
