The Porsche Taycan is an all-electric car made by German automobile manufacturer Porsche. It was first unveiled as a concept car named Mission E at the 2015 Frankfurt Motor Show, then in production form at the 2019 Frankfurt Motor Show. As Porsche’s first series production electric car, it will be sold in several variants at different performance levels, and may spawn further derivatives in future models. Around 4,480 Taycans were delivered in the first half of 2020, its debut sale year.

Design

The car’s interior features Porsche’s first fully digital instrumentation, with up to four digital displays, including a curved, free-standing 16.8-inch configurable driver’s display. A 10.9-inch screen to the right of the instrument cluster is the car’s infotainment center. An optional screen to the right of the infotainment screen allows the front passenger to customise the infotainment system. On the centre console, an 8.4-inch portrait-oriented, trackpad-controlled screen shows the powertrain’s status and advises the driver on using the car’s power efficiently. In contrast with the all-digital layout, the dashboard features the classic Porsche clock at its top.

The exterior styling, by former Porsche Exterior Designer Mitja Borkert, is strongly influenced by the Mission E concept car, retaining most of its design elements except the “suicide doors” and B pillars. Design features include a retractable rear spoiler, retractable door handles, and an advanced regenerative braking system. Taking full advantage of its drivetrain layout, the Taycan combines the fundamental short-nosed front proportions of traditional Porsches with the stretched proportions of modern front-engine models towards the rear, providing clear design links to existing models. The front features four-point LED daytime running headlamps. At the rear, the car has a short notchback-style boot lid, housing a full-width light band serving as taillights and turn signals and providing access to one of two luggage compartments. The other compartment is under the bonnet, with a claimed capacity of nearly 100 litres. The Taycan Turbo and Turbo S models include carbon-fibre trim and 20-inch wheels.

Specifications

The Taycan’s body is mainly steel and aluminium joined by different bonding techniques. The body’s B pillars, side roof frame and seat cross member are made from hot-formed steel, while the bulkhead cross member is made from boron steel to improve safety. The shock absorber mounts, axle mounts and rear side members are forged aluminum; and all body panels, except the front and rear bumpers, are also made from aluminum to reduce weight. 37% of the car is aluminium.

The Taycan uses a new battery-electric all-wheel-drive drivetrain with a permanent-magnet synchronous motor on each axle. At the front, power is sent to the wheels through a single-speed gearbox (8.05:1 gear ratio); and at the rear, through a two-speed transmission and a limited slip differential. The gearbox has a short planetary first gear (15.5:1) providing maximum acceleration, and a long-ratio second gear (8.05:1) delivering top speed and efficiency. Power comes from a 93 kWh 630 kg (1,389 lb) lithium-ion battery pack that doubles as a structural chassis component and keeps the center of gravity low. To increase rear-seat legroom, recesses called “foot garages” have been incorporated in the battery pack. The 723-volt pack (835 volt full, 610 volt empty) has 33 modules with 12 LG Chem pouch cells each, for 396 cells in total.

The car’s range depends on how it is driven and what driving mode is selected. There are five driving modes: Sport, Sport Plus, Normal, Range, and Individual. The Range mode maximizes range with lowest power consumption; and Individual lets the driver customise various settings. Regenerative braking provides up to 265 kW, yielding a deceleration of 0.39 G.

Porsche has developed an 800-volt charging system specifically for the Taycan. According to manufacturer estimates, the battery pack can be charged from 5% to 80% in 22.5 minutes in ideal situations, using a DC fast charger with 270 kW of power. Charge times depend on weather conditions and infrastructure. When purchasing a Taycan, owners receive three years free access to the speed-charging infrastructure of IONITY, Porsche’s joint venture partner.

To reduce charge times at both hot and cold temperatures, the battery can be thermally preconditioned using a charging planner. Owners set a departure time in the planner, and the car automatically warms or cools the battery for optimal charging times. A charging dock and mobile charger, supplied with the car for home charging, utilize a 9.6-kW connector that charges the car in 11 hours. An energy manager, which can also be installed in a home’s circuit panel, can manage the house’s power flow; provide cost-optimising charging using solar power; and provide blackout protection by reducing the charge to the car if household appliances such as fridges or dryers turn on and exceed the panel’s power threshold.

The Taycan Turbo has a drag coefficient of Cd=0.22, which the manufacturer claims is the lowest of any current Porsche model. The Turbo S model has a slightly higher drag coefficient of Cd=0.25. The frontal area is 2.33 m², with a resulting drag area of 0.513 m² and 0.583 m² for the Turbo and Turbo S, respectively.
