Porsche finetunes E-Performance for future series models
Developed together by Porsche and Audi
With PPE, Porsche and Audi have together developed an architecture for all-electric cars with which the benefits of a purely electric platform can be enjoyed in many ways – in terms of package and spaciousness, for example. At the same time, the architecture offers so much room for manoeuvre in the wheelbase, track width and ground clearance that it can be used to realise a variety of models – including in different segments, which simultaneously allows the flexibility for Porsche models to retain their strong, independent character.
The first Porsche based on the PPE will be the all-electric Macan. With its 800-volt architecture, the powerful electric motor of the latest generation, and state-of-the-art battery and charge management, this model offers the E-Performance that is characteristic of Porsche. The successor to the successful compact SUV will be the sportiest model in its segment. Along with reproducible best-in-class performance values, the development targets include long-range capability and high-performance fast charging.
Battery: From five to 80 per cent charged in less than 25 minutes
All electric Macan models have a lithium-ion battery in the underbody with a total capacity of about 100 kWh. This sizing is based on the Porsche philosophy. When looking at how to balance range, performance and sustainability, the company focuses on travel time. High-performance battery and charging technology is key here.
The battery in the future all-electric compact SUV from Porsche consists of 12 modules with prismatic cells. The mixing ratio of nickel, cobalt and manganese is 8:1:1, and the battery achieves a higher energy density. Thanks to 800-volt technology, the first PPE model series from Porsche will be charged with an even higher charging capacity than the 270 kW of the Taycan. At a suitably powerful fast-charging station the battery charge level can be increased from five to 80 per cent in less than 25 minutes.
Porsche Traction Management (PTM) uses the advantages of the all-electric powertrain
Porsche Traction Management (PTM) makes use of the conceptual advantages of the all-electric powertrain. Like the Taycan, the electric Macan will have an all-wheel concept with one electric motor per axle. The two electric motors enable fast, precise all-wheel control and a fully variable and – depending on the driving programme selected and the respective driving situation – demand-based torque distribution between the front and rear axles. This is beneficial to the steerability and the directional control of the front axle on the one hand, and on the other to the traction as the basis for the characteristic Porsche handling with high agility. Even away from paved roads, the Macan benefits from the optimised all-wheel distribution of the electronically controlled all-wheel drive.
