Porsche launches the extensively updated Taycan.
The new model variants offer more range as well as shorter and more robust charging processes.
During an initial range test from Los Angeles to San Diego and back, pre-series models demonstrated their further improved efficiency.
The all-electric sports cars covered up to 587 kilometres on one battery charge on public roads.
The range test was carried out under everyday conditions.
Twelve international media representatives drove four Taycan sports saloons and a Taycan Cross Turismo on three days on Interstate Highway 405 and 5 between the Southern Californian metropolises of Los Angeles and San Diego.
The teams drove at the maximum speed of 75 mph permitted on interstates.
This corresponds to around 120 km/h.
All four test cars were equipped with the larger Performance Battery Plus.
The Cross Turismo 4 with 21-inch tyres had a range of up to 512 km.
The Taycan Turbo covered up to 555 km with a wheel and tyre combination of the same size.
The Taycan 4S on 20-inch tyres managed up to 552 kilometres on a single battery charge.
The Taycan with rear-wheel drive and 19-inch tyres managed an even more impressive 587 km.
The outside temperature peaked at around 26 degrees Celsius.
The highway was dry on the first two test days and very wet on the last day.
The cars were charged at the Electrify America Charger in Torrance/Los Angeles.
Here, the Taycan demonstrated over 300 kW charging power for many minutes and was able to charge from 10 to 80 per cent state of charge several times in well under 20 minutes.
The charging performance, charging time and the time it takes to start charging were also greatly improved in this test.
