It appears that Porsche might be preparing something special for Taycan reservation holders. While it has previously been hinted that the German carmaker will be revealing three versions of the vehicle — the base Taycan, the Taycan 4S, and the Taycan Turbo — recent reviews from select auto publications are suggesting that Porsche is set to include a fourth variant on its upcoming unveiling: the Taycan Turbo S.

The Porsche Taycan is based on the Mission E sedan concept, which was unveiled in 2015 to critical acclaim. The Mission E featured over 600 hp from its twin electric motors, allowing it to achieve a 0-60 mph time of less than 3.5 seconds. The Mission E sedan’s specs appear to be the closest to the Porsche Taycan Turbo, which is speculated to have a starting price of $130,000 before options.

In a recent review of the Taycan, motoring publication Autocar noted that both the Turbo and the Turbo S variant will have standard power outputs that are substantially over 600 bhp, and both will have an “overboost” function for 2.5 seconds at a time. The two top-tier Taycan variants’ overboost will have some differences, as the Turbo S’ overboost will raise the vehicle’s output to well over 700 bhp, with over 750 lb-ft of torque.

The result of this is a 0-60 mph time that is well below the 3-second mark. This makes the Taycan Turbo S acceleration very close to the roller-coaster-like launch of a Tesla Model S Performance, which has a 0-60 mph time of 2.4 seconds. Considering that the Taycan has been extensively tested in the Nurburgring, the Turbo S version of the vehicle will likely be a formidable car on the track.

Apart from the vehicle’s performance, the motoring publication also revealed some standard equipment that will be equipped on the Taycan Turbo S. The magazine notes that the Turbo S will be equipped with ceramic brakes, a stiffer set-up, standard four-wheel steering, 21″ wheels and high-performance tires.

The Porsche Taycan is set to be unveiled next week on September 4, 2019 at 9 a.m. EST. The vehicle will be launched at three locations: one in Canada, one in Germany, and another in China. Pricing for the base Taycan, which will reportedly be equipped with a single motor and an 80 kWh battery pack, is expected to be in the low ~$90,000 range. The mid-range Taycan 4S, speculated to be priced at the high ~$90,000 range, is estimated to be fitted with two electric motors and a 96 kWh battery pack.

The two top variants of the Taycan are expected to command a notably higher price, with the Turbo version starting at $130,000 before options. Pricing for the Turbo S is yet to be announced, though considering that the Porsche Panamera Turbo S E-Hybrid Sport Turismo commands a ~$190,000 price, it wouldn’t be surprising if the Taycan’s fastest iteration ends up being priced closer to the next-gen Tesla Roadster than the Model S.
