Extensive details pertaining to the upcoming all-electric Porsche Taycan have emerged.

The information comes from British publication CAR magazine, whose European editor Georg Kacher hitched a ride in a prototype Taycan up the hill at the recent Goodwood Festival of Speed.

According to the publication, three model grades will be offered at launch: the base Taycan, Taycan Carrera 4S and Taycan Turbo. This appears to confirm a rumour from January, when the naming structure was announced by American journalist Alex Roy in a tweet.

The entry-level model – simply known as ‘Taycan’ – is set to store its power in an 80kWh lithium-ion battery, with the rear wheels driven by electric motors available in 240kW or 280kW guises. Previous rumours have suggested the sedan will be priced between the Cayenne and Panamera, meaning a $110,000-$210,000 sticker price Down Under.

The mid-spec Taycan, reportedly known as the ‘Carrera 4S’, is rumoured to up the battery size to 96kWh, with an unknown range increase to boot. CAR claims it will be all-wheel-drive, with the electric motor system available in 320kW or 360kW setups.

Tipped to sit atop the range is the flagship ‘Turbo’, powered by a 96kWh battery and a multi-motor all-wheel-drive system producing over 440kW of power and 880Nm of torque, with 1000Nm on tap during 10-second periods of ‘overboost’.

The British publication claims the vehicle will utilise a two-speed transmission.

CAR estimates the top-spec car can do 0-100km/h in 3.2 seconds, 0-200km/h in less than 10 seconds, and can achieve a 260km/h top speed it claims can be sustained for considerable periods of time “without battery heatstroke”.

Other Turbo features and specifications reported by the publication include a 515km range (though on which cycle is not stated), a 2095kg kerb weight, air suspension, configurable regenerative braking, standard tungsten-carbide brakes borrowed from the Cayenne, as well as the ability to do ten 0-100km/h sprints (or four 0-200km/h runs) without losing any performance.

In terms of charging, CAR states that from launch the pure-electric Porsche will only be able to charge at 250kW, with the 350kW rate previously promised by the German brand – confirmed to be capable of adding 100km of range in four minutes – not scheduled to be available until 2021.

The magazine also claims two additional variants are in the works, but have not been signed off for production: a full-fat 540kW all-wheel-drive Turbo S, and a lighter, rear-drive GTS. It is unclear when these would be revealed, though it would likely be sometime in 2020 or 2021.

Official details will be confirmed later this year, when the covers are taken off the Porsche Taycan at the Frankfurt motor show in September. Stay tuned to CarAdvice for all the latest.
