As part of the project, the developers at Siemens Corporate Technology are focusing on two areas: creating a modular powertrain and giving the vehicle a smart charging ability. This research is necessary because electric vehicles need to meet a wide range of requirements before they can be used on a wide scale. Upper-range vehicles, in particular, need to offer high ride comfort, great handling, and, if possible, high speed. In addition, it must be possible to easily integrate the vehicles into future smart grids.
One of the drive concepts is similar to a traditional combustion engine vehicle in that it features a centrally mounted motor. Although this is currently the most common type of electric vehicle, it is also the one with the least flexibility. All of the project’s other concepts have a double motor. In one of them, the two motors are linked and have a manual transmission with two automatically shifting gears. The result is fast acceleration and high top speeds, both of which are important requirements for a sports car. In the second double motor concept, the two motors operate separately. This variant enables torque vectoring, in which controlled individual drive torques are distributed to the rear wheels. The system opens up completely new possibilities with regard to vehicle handling.
The developers plan to use flexible high-performance electronics to hook the vehicle up effectively to a smart grid. These electronic systems will be used for driving the vehicle as well as for charging purposes. It will be possible to charge the vehicle at an output of up to 22 kilowatts and the car will also be able to feed electricity back into the grid. A total of 10 test vehicles will be built. They will be used in tests in Berlin and the greater Munich area in order to gain insights into how the entire vehicle can be further optimized.

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
