The first luxury electric sports car from Exagon Motors will be entering into production from the beginning of 2014. These innovative vehicles boast two liquid-cooled electric motors from Siemens that include assemblies from HUBER+SUHNER.

Each year, between 150 and 300 Furtive-eGT sports cars from Exagon Motors will hit the roads. These exclusive vehicles feature two 201 HP electric motors from Siemens. Capable of accelerating from 0 to 100 km/h in just 3.5 seconds, they can achieve a top speed of 250 km/h.


Siemens is using connectivity solutions from HUBER+SUHNER to connect each 148 kW electric motor. For this project, the cable manufacturer is supplying power cables and motor signal cables. The latter comprise multi-core, shielded RADOX signal cables together with various connectors. These assemblies connect the electric motors with a range of control units for monitoring the motor operating temperatures and other functions.


RADOX battery cables are also used to connect the two Siemens motors with the inverters. These inverters convert the energy generated by the 53 kWh lithium-ion batteries into 3-phase alternating current, which is then conveyed to the motor via three shielded RADOX battery cables.


RADOX cables from HUBER+SUHNER are particularly well suited to the demanding conditions in the motor compartment. Thanks to their electron-beam crosslinked insulation material, they are capable of withstanding temperatures ranging from -70 °C to +150 °C (3000 h). They are also highly resistant to thermal pressure, abrasion and fluids including fuel, oil, battery acid, salt water and detergents. All of which makes RADOX cables ideal for providing long-lasting, secure connections in the motor compartment.


HUBER+SUHNER delivers more than just high-quality cable assemblies. Its team of application engineers based in Weikersheim, Germany, is also on hand to lend its industry expertise to customer projects. In this project for instance, HUBER+SUHNER will be required to propose solutions for as yet unclarified aspects, such as the best way to seal the low voltage cable harness.


HUBER+SUHNER has been providing innovative and safe connectivity solutions ever since electric and hybrid vehicles first entered into production. “We offer longstanding experience of the automotive industry together with industry certification. This is coupled with our extensive knowledge of cable production and high-quality products,” explains Rudi Löw, salesperson at HUBER+SUHNER. These are all factors that have managed to impress Siemens.
