Stuttgart/Lahr. Brand-typical performance that can be reproduced as often as you like: the electric drivetrain of the
A pre-production version of the over 440kW (600PS) all-wheel drive vehicle accelerated from 0 to 200km/h 26 times in a row during an initial test. The venue for this sprint challenge was Lahr airfield in southern Baden. The test drives were documented on the YouTube channel, “Fully Charged”, and resulted in an average acceleration time of just under ten seconds. The difference between the fastest and slowest trial was just 0.8 seconds.
The test runs took place in both directions on the airfield's taxiway. The entire approximately 2.3-kilometre track was used. The outside temperature was 28 degrees Celsius.
A whole raft of technical innovations allow the
• The two powerful electric motors on the front and rear axles are so-called permanent-magnet synchronous motors (PSMs). These have a rotor with high-quality permanent magnets that generate a natural magnetic field. The rotor moves synchronously with the stator's rotating magnetic field, hence the name PSM. The pulse inverter (PI) specifies the frequency of the rotating field in the stator, thus determining the rotor speed. Thanks to their design and operation, as well as their excellent thermal behaviour, permanent-magnet synchronous motors are capable of delivering and repeatedly reproducing the high performance typical of

• Thermal management, combined with the drivetrain concept (PSM and 800-volt technology), ensures high reproducibility. Needs-based cooling achieves sports car-typical performance - multiple times over, if required.
Opened in 1913 as a Zeppelin airfield, Lahr was used as a military air base after the Second World War, first by French troops and then by Canadian NATO troops from 1967. Since the latter withdrew in 1994, ADAC Südbaden has held motorsport events on the site. From 1996 to 1998, Formula 1 and Touring Car races were held on the so-called Regio-Ring, some attracting over 30,000 spectators. Located just off the A5 motorway (Karlsruhe/Basel), the airfield is now used for corporate and freight flights, as well as for test and measurement drives by the automotive industry.
