Engineers have driven the new Porsche Taycan in more than 30 countries as it nears completion of its testing regime before entering series production.
Test models of the first pure electric sports car from the German marque have been driven at temperatures from -35C to +50C, at altitudes from 85 metres below sea level to 3000m above, and in air humidity conditions from 20 to 100 per cent.
It's had to prove its driving dynamics on snow and ice a few kilometres from the Arctic Circle in Scandinavia and in hot-climate endurance runs in Dubai.
When Porsche's 1000-strong development team of test drivers, technicians and engineers finish work, the battery technology will have completed more than 100,000 charging cycles using various technologies across the globe.
"After carrying out computer simulations and comprehensive bench tests early on, we have now reached the final phase of this demanding testing programme," said Stefan Weckbach, vice-president of the model line.
"Before the Taycan is launched on the market at the end of the year, we will have covered approximately six million kilometres across the globe. We are already very happy with the current status of the vehicles. The Taycan is going to be a true Porsche," he said.
The Taycan will accelerate from 0-100km/h in significantly less than 3.5 seconds and have a driving range of more than 500km (according to the NEDC test cycle).
Porsche says its electric cars undergo the same rigorous testing programme as sport cars with combustion engines, to verify their performance and unrestricted suitability for everyday use in all climate conditions.
Particularly demanding features, such as charging the battery or temperature control of the drive train and the interior under extreme conditions, are additional aspects in the battery-powered models.
Real world testing is additional to the findings from the initial testing stage using digital prototypes.
Computers were used to design the body, drive, chassis and electronics of the new model and to simulate their functions.
In total, the virtual prototypes have completed more than 10 million digital kilometres.
The Taycan will be introduced in September and launched on to the Europe market at the end of this year.
Across the globe, more than 20,000 serious prospective buyers have put their names down on an option programme list and paid a deposit.
