With its electric vehicle MUTE, the Technische Universitaet Muenchen (TUM) presents the first publicly visible result of its research program TUM.Energy. MUTE will showcase the TUM's answer to future challenges in personal mobility at the International Motor Show (IAA) in Frankfurt. MUTE is a purely electric, energy-efficient vehicle that meets all requirements of a full-fledged car. With MUTE, the 20 involved departments present a strategy for manufacturing a mass-production vehicle at an overall cost on par with that of comparable combustion engine vehicles.

With MUTE, researchers from the TU Muenchen have created an agile, sporty two-seater for regional road traffic. It has space sufficient for two persons plus luggage. The L7E certified electric motor, which is electronically limited to 15 kW, accelerates the light vehicle to 120 km/h. The lithium-ion battery is designed to guarantee a range of at least 100 kilometers. When needed, a zinc-air battery serves as a range extender – a "reserve" battery, as it were. Its sporty suspension and the active torque vectoring differential drive ensure good cornering stability and excellent driving performance.
The MUTE design conveys a snazzy, self-confident appearance. The built-in features fulfill all essential requirements of a modern road vehicle. A safety package, including an electronic stability program (ESP) system, a robust passenger compartment and crash elements made of carbon fiber reinforced plastic, imparts a high level of safety to the vehicle. Regarding ergonomics and comfort, here too, the MUTE concept leapfrogs other developments to date in the L7E class.
Decisive for the great efficiency of the MUTE is its low weight. A stable vehicle frame made of aluminum and a chassis made of carbon fiber reinforced plastic reduces the curb weight, including batteries, to a mere 500 kilograms. "Low weight is essential for an electric vehicle," says the TUM vehicle engineer Prof. Markus Lienkamp. "Greater weight requires more battery performance for the same range, which results in higher costs. Greater weight also results in reduced dynamics for a given power output. But we want a car that is affordable and fun to drive."
A further contribution to efficiency comes from the torque vectoring differential: A small electrical motor in the differential that functions both as a motor and as a generator serves to ideally distribute the forces between the two back tires. Especially when braking in curves, twice as much energy can be recovered as without the torque vectoring technology. At the same time, the advantageous distribution of drive and braking forces makes the car much more agile and also safer.
MUTE has been newly developed from scratch. Every part has been optimized for three main factors: efficiency, low overall cost and safety. Extensive preliminary studies were carried out to ascertain what mobility of the future will look like, what customer requirements will be decisive in purchasing decisions and how these might be fulfilled in a cost-effective and weight-saving manner. This led, among other things, to all tertiary user interface elements (e.g., for navigation and infotainment) being collected into a central touchpad. In addition, the touchpad computer can be used as a mobile interface for server-based, value-added services. This will allow the owner to check the current charging status using a smartphone. While underway, the most energy-efficient route (not only the shortest or fastest) can be determined based on the current traffic situation.
Over 200 staff members of 20 departments of TU Muenchen's Science Center for Electromobility joined forces to develop the MUTE concept. The research network belongs to the cross-faculty research initiative TUM.Energy, which bundles the extensive, long-term research activities of more than 100 departments in eight faculties on the topic of energy to a competence center with international prominence. The Science Center for Electromobility provides testing infrastructure, central test beds and the possibility for building shared prototypes. At the same time it is a docking station for national and international cooperation with research departments in industry and academia. The MUTE prototype was built with funding from the university budget and the Bavarian Research Foundation (BFS); project partners were C-CON, Gerg RPT and IAV. R&R KFZ did the vehicle construction. The TUM holds the intellectual property rights for overall concept. Over 30 partners from industry support the project as a whole.
MUTE represents the official start of the MUNICH SCHOOL OF ENGINEERING, which places its research focus on the key future topic of "Energy – Green Technologies," and educates particularly well-qualified engineering students with an emphasis on research and interdisciplinary.Contact : Prof. Markus Lienkamp

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
