By the time the all-electric Macan hits the market in 2023, it will have driven some three million test kilometers around the world in varying conditions.
The all-electric Macan is scheduled for market launch in 2023.
After the completion of the first tests on the proving ground of the Porsche Development Center in Weissach, Macan’s all-electric prototypes are now heading outside the premises of Porsche for the first time. The market launch of the all-electric Macan – the first Porsche to be built on the Premium Electric Platform (PPE) – is scheduled for 2023. The new combustion-engine Macan models will be offered alongside the all-electric Macan in the future. By the time the all-electric Macan hits the market in 2023, it will have driven some three million test kilometers around the world in varying conditions. Prototypes are able to incorporate the experience gained from countless previous test miles – conducted in virtual space.

Digital development and testing not only saves time and costs, but also conserves resources, which improves sustainability. Instead of real vehicles, engineers use digital prototypes – computational models that replicate a vehicle’s properties, systems, and power units with great precision. There are 20 digital prototypes for simulation purposes in a number of development categories, such as aerodynamics, power management, operations and acoustics.
Aerodynamics specialists are among the first engineers to work with a digital prototype. The low aerodynamic drag is fundamental for the all-electric Macan in order to ensure a long range. Even minor improvements in throughput can make a huge difference. Engineers are currently using simulations to refine details such as cooling air ducts. The calculations not only take into account the different arrangements of the components, they also reflect the actual temperature differences.
The electric drive system – from battery to engine – requires a completely separate cooling and temperature control concept, very different from that of a conventionally powered vehicle. While a 90-120 degree temperature window is the target for combustion engines, the electric motor, powertrain electronics, and high-voltage battery require a range of 20-70 degrees, depending on the component. Critical scenarios do not occur on the road, but during high power fast charging at high outside temperatures. However, Porsche developers are able to accurately calculate and digitally optimize position, flow and temperature.

Virtual prototypes can be combined with real world scenarios at an early stage. The best example here is the development of a completely new display and control concept for the next generation of Macans. By using a so-called seat box to recreate the driver’s environment, the display and concept of operation can come to life in an early stage of development in conjunction with the digital prototype.
The first physical prototypes of the all-electric Macan were built on the basis of data obtained from the simulations – in some cases in an elaborate manner by hand or using special tools. These are then regularly adapted according to the virtual refinement process.
