The all-electric Macan is ready for the road: after initial testing on the proving grounds of the Porsche Development Centre in Weissach, the well-camouflaged next-generation prototypes of the compact SUV are now heading outside Porsche premises for the first time.<\/p>\n\n\n\n\n\n\n\n

\u201cTesting in a real-life environment is now getting underway \u2013 one of the most important milestones in the development process,\u201d says Michael Steiner, Member of the Executive Board, Research and Development, at Porsche AG. By the time the all-electric Macan is launched onto the market in 2023, it will have covered some three million test kilometres worldwide in varying conditions. The prototypes are able to incorporate the experience gained from countless previous test kilometres \u2013 driven in a virtual space.<\/p>\n\n\n\n

The aerodynamics specialists are among the first engineers to work with a digital prototype. \u201cWe started with a flow-around model when the project first started about four years ago,\u201d reports Dr Thomas Wiegand, Director of aerodynamics development. Low aerodynamic drag is fundamental to the all-electric Macan with a view to ensuring a long range. Even minor flow enhancements can make a huge difference. The engineers are currently using simulations to fine-tune details such as the cooling air ducts. The calculations not only take into account different arrangements of the components, they also reflect real-life temperature differences.<\/p>\n\n\n\n

Virtual testing with the new display and operating system<\/strong><\/a><\/h4>\n\n\n\n

New methods now allow very precise simulation of both aerodynamics and thermodynamics. \u201cThe digital world is indispensable to the development of the all-electric Macan,\u201d says aerodynamics expert Wiegand. The electric drive system \u2013 from the battery through to the motor \u2013 requires a completely separate cooling and temperature control concept, one that is very different from that of a conventionally powered vehicle. While a temperature window of 90 to 120 degrees is the target for combustion engines, the electric motor, powertrain electronics and high-voltage battery require a range of between 20 and 70 degrees, depending on the component. The critical scenarios don\u2019t occur on the road but during fast high power charging at high outside temperatures. However, the Porsche developers are able to precisely calculate and digitally optimise position, flow and temperature.<\/p>\n\n\n\n

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 operating concept for the next generation of Macan. Using what is known as a seat box to recreate the driver\u2019s environment, the display and operating concept can be brought to life in an early development phase in conjunction with the digital prototype. \u201cSimulation allows us to assess displays, operating procedures and the changing influences during a journey from the driver\u2019s point of view,\u201d explains Fabian Klausmann of the Driver Experience development department. Here, the ‘test drivers’ are not just the specialists themselves but also non-experts. This allows all interaction between driver and vehicle to be studied down to the last detail, enabling selective optimisation even before the first physical cockpit has been built.<\/p>\n\n\n\n

Development goal: to be the sportiest model in the segment<\/strong><\/h4>\n\n\n\n

The first physical prototypes of the all-electric Macan were built based on the data obtained from the simulations \u2013 in some cases elaborately by hand or using special tools. These are then regularly adapted based on the virtual refinement process.<\/p>\n\n\n\n

 By the same token, the findings from road testing are fed directly into digital development. \u201cEndurance testing on closed-off testing facilities and public roads in real-life conditions is still indispensable to ensure that the vehicle structure, operational stability and reliability of hardware, software and all functions meet our high quality standards,\u201d says Member of the Executive Board Michael Steiner. <\/p>\n\n\n\n

The demanding test programme for the all-electric Macan, carried out under the extremes of climatic and topographical conditions, includes disciplines such as the charging and conditioning of the high-voltage battery, which has to meet very rigorous standards. \u201cLike the Taycan, the all-electric Macan, with its 800-volt architecture, will offer typical Porsche E-Performance,\u201d promises Steiner, citing development goals such as long-distance range, high-performance fast charging and reproducible best-in-class performance figures: \u201cThe all-electric Macan will be the sportiest model in its segment.\u201d<\/p>\n\n\n\n

Another new Macan with a combustion engine<\/strong><\/h4>\n\n\n\n

The market launch of the all-electric Macan \u2013 the first Porsche to be built on the Premium Platform Electric (PPE) \u2013 is planned for 2023. Porsche is positioning itself flexibly for the transition to pure electromobility. \u201cIn Europe, demand for electric vehicles continues to rise, but the pace of change varies considerably across the world. That\u2019s why we\u2019re going to launch another conventionally powered successor to the current Macan in the course of 2021,\u201d says Michael Steiner. The new combustion-engined Macan models will be offered alongside the all-electric Macan in the future. Until then, however, it still has millions of test kilometres to cover \u2013 both in real life and virtually.<\/p>\n\n\n\n
