With the Porsche Taycan, launched in 2019, the manufacturer unveiled its first 100% electric saloon. The challenge was twofold: meeting demand for zero-emission vehicles while staying true to a performance-driven DNA. Electric motors deliver their maximum torque instantaneously, which places enormous strain on conventional transmissions. The answer lies in an exceptional component: the Porsche Taycan gearbox, a highly precise two-speed automatic gearbox. EDEN BOITES takes you through this technology.
An ultra-high-performance electric saloon
The first Taycan models produced between 402 and 761 horsepower. In 2023, the Turbo GT variant, fitted with a 760 kW motor, reaches 1,034 horsepower and a maximum torque of 1,340 Nm. This colossal torque, available from the moment you pull away, made pairing the car with a conventional transmission a significant challenge. Porsche therefore engineered a bespoke solution.
How the two-speed gearbox works
To handle the torque, the Taycan uses two motors — one at the front, one at the rear. The two-speed automatic gearbox is paired with the rear motor, while the front motor is coupled to a single-speed transmission. First gear harnesses the instantaneous torque and absorbs the stresses of hard acceleration; second gear, with its longer ratio, is used at higher speeds. Smooth gear changes are achieved via a multi-disc clutch that distributes torque across several discs to limit wear. This clutch is integrated with a planetary reduction gear that adapts the rotational speed, while a dog clutch mechanically locks the engaged gear. This gearbox is fitted across the entire Taycan range.
Key maintenance tips
As a cutting-edge piece of technology, the Taycan's gearbox demands careful attention:
- periodically check the transmission fluid level, keeping within the recommended limits — a fluid change is not normally required;
- carry out regular software and hardware updates;
- inspect the multi-disc clutch and the cooling system, including its fluid;
- coordinate maintenance of the motors and gearbox, as these components are closely interlinked.
Diagnosing and repairing the gearbox
Natural wear, inadequate lubrication, impact damage or an installation error are among the most common causes of malfunction. Certain signs, such as unusual noises, can point the diagnosis in the right direction, but repair always requires removal of the gearbox. This involves disconnecting the electrical connections and cooling lines, removing adjacent components, and then carefully extracting the gearbox. A thorough inspection of the seals and internal components follows, along with replacement of the faulty part and reassembly. It is a complex operation, best left to a professional.
Replace rather than repair
When repair proves too extensive or the gearbox shows advanced wear, replacing it with a reconditioned gearbox is a sound alternative.

Frequently asked questions
How many speeds does the Taycan gearbox have?
The Taycan uses a two-speed automatic gearbox on the rear motor, while the front motor is connected to a single-speed transmission.
Does the Taycan gearbox need a fluid change?
A fluid change is not normally required. However, the fluid level should be checked regularly and the manufacturer's recommendations followed.
Why only two speeds?
First gear harnesses the instantaneous torque at pull-away, while second gear prioritises efficiency at high speed: two speeds are sufficient to cover the entire operating range.
Repair or replace in the event of serious damage?
In the case of advanced wear, a reconditioned gearbox on an exchange basis often offers better reliability than a costly repair.
