Development of the all-electric Porsche Mission E appears to be going at a steady pace ahead of its 2019 debut. Automobile Magazine managed to snag a drive in the original concept car from 2015, and while there’s not much that can be gleaned of the production model from a show car, the publication did rattle off a few technical details that it got from sources familiar with the car.

According to the drive report, the company is considering three variants for the Mission E, tentatively rated at 300 kW (402 hp), 400 kW (536 hp) and 500 kW (670 hp). These cars will carry names that mirror other model lineups in the Porsche range, which would likely mean standard, S and GTS badges.

Power will come from two motors on four-wheel drive versions (a base rear-drive variant could be offered later), a 160 kW (215 hp), 300 Nm front motor with 441 Nm of torque on overboost, and a more powerful rear motor. Two outputs are available for the latter – 240 kW (322 hp) and 340 Nm and 320 kW (429 hp) and 550 Nm – and there’s also a two-speed transmission and an optional electronic limited-slip differential.

Stats revealed during the unveiling of the Mission E Concept at the 2015 Frankfurt Motor Show included a zero-to-100 km/h sprint time of under 3.5 seconds and to 200 km/h in less than 12 seconds. There’s also a range of over 500 km, along with a proprietary Turbo Charging system that will provide more than 400 km of range in around 15 minutes.
