In a move aimed at imbuing the Taycan with the sort of rear-biased handling traits that have characterised Porsche models through the years, the two electric motors have varying outputs, with the one at the rear more powerful than the one at the front. A torque vectoring function on both axles also regulates the amount of drive sent to each individual wheel.
A rear-wheel-drive version of the Taycan, featuring a single electric motor on the rear axle, is also currently undergoing production as part of a planned 200-strong fleet of prototypes and pre-production examples. Sighted by Autocar on the production line in Zuffenhausen, it's expected to be offered from the start of sales as part of a multi-tiered line-up similar to that of other Porsche models.
The channelling of drive is handled by a two-speed gearbox - a choice that also differs from the single-speed gearboxes used by most electric cars. This has been chosen for its ability to provide a second gear for sustained high-speed performance, which Porsche considers crucial if its new electric car is to make a mark on typical Porsche customers.
Porsche plans to offer the Taycan with a number of different power outputs in a strategy not dissimilar to that of Tesla with the Model S, which comes in 75D, 100D and P100D guises. Nothing is confirmed, but officials suggest variants with up to 402bhp, 469bhp, 536bhp and, at the top of the range, 603bhp are being developed, but it remains to be seen whether they will all be offered for sale over the car’s planned seven-year lifecycle.
In range-topping four-wheel-drive 603bhp guise, the Taycan is expected to eclipse the 3.5sec 0-62mph time announced at the unveiling of the Mission E, placing it on a similar performance plane to the 911 Turbo for acceleration. Although the top speed has yet to be announced, it's claimed to be “well over 200kmh [124mph]”.
One factor Porsche is pushing heavily in the lead-up to the launch of the Taycan is its ability to provide what it describes as reproducible performance.
“Drivers won’t need to worry about throttling performance,” said Weckbach. "The Mission E will offer reproducible performance and a top speed that can be maintained for long periods.”
Electrical energy used to run the electric motors is stored in a battery that uses cells supplied by Korean company LG. The capacity of the lithium ion unit has yet to be revealed, but Porsche is sticking to earlier claims that the Taycan will have a range of up to 311 miles.
The Taycan's charging set-up
A retractable body element located behind the Taycan's front wheel arch provides access to the charging port. Porsche is also working on inductive charging, although it won’t be drawn on whether it will be available as an option from the start of sales.
Porsche has developed an 800V charging system for the Taycan to fulfil an early pledge that its first electric model would be fast not only to drive but also to recharge.
"With the 800V technology, it can be recharged in just over 15 minutes for a range of around 400km [249 miles], so it only takes about half as long compared to today's systems," said Weckbach.
As well as providing fast charging, the 800V system allows the Taycan to use a lighter and more compact wiring loom than if it had chosen a more widely used 400V system – all apparently without any crucial safety concerns. Despite this, the car is still expected to tip the scales at more than 2000kg.
