Substantially different, in fact: the electric Macan will be based on an evolved version of the platform used for the new Taycan.
It will be based on the Volkswagen Group’s new Premium Platform Electric (PPE) architecture, developed from the Taycan’s J1 platform to allow the physical flexibility required when low-slung GTs and high-riding SUVs share the same hardware.
Additionally, Porsche deputy chairman Lutz Meschke told Automotive Daily that the platform, currently reserved for Audi and Porsche models only, saves 30% of costs from developing its own architecture. It will be used by Audi for a Q5-sized sibling model to the Macan EV, called the Q6 E-tron.
Despite the models’ differing roles, Baumann said: “There are no real differences in the challenges of developing the Taycan and Macan. The current Macan is not so aerodynamic and we’re working hard on this. It’s the Taycan team working on it. With the Taycan, we haven’t given anything up to get the aerodynamic performance and I’m confident it will be the same for the Macan. The 600kg battery isn’t beneficial to dynamics, but the low centre of gravity is an advantage.”
Being a purpose-built all-electric model, there’s no need to package a conventional powertrain up front, allowing for a lower nose, Baumann added.
“The design of the electric Macan is the next step, but it will be immediately recognisable,” he said, despite it having “no common body structure” with today’s Macan.
Although the existing Macan received a facelift in 2018, four years after it was launched, the model is now likely to live for longer than originally planned as Porsche hedges its propulsion bets. Another facelift, predominantly focused on updating technology and the model line-up, will be revealed in the coming weeks.
Meschke suggested the overlap for internally combusted and full-electric Macans will be “a couple of years”. The take-up of electric cars is growing but at different rates in different countries, not least because the infrastructure is only patchily appearing and isn’t always reliable.
“It’s difficult to say when the transformation will end. It’s different by region,” said Baumann. However, Meschke predicts that “30-40%” of Porsches sold will be all-electric in five years’ time.
Baumann added that the new Macan will “maintain the DNA of the previous model. It’s our biggest seller. We’ll keep the spirit. It’s the sportiest model in the segment.”
Despite the performance potential of the PPE architecture, which delivers sub-3.0sec 0-100km/h with the Taycan, the Macan EV will not be a coupé-SUV. Baumann said: “We need to keep the everyday usability. It’s usually the main vehicle in the household.”
The electric version will provide four-wheel drive, using a motor to drive each axle. The most powerful version will potentially be able to offer around 520kW and 1020Nm, though Porsche will want to keep some performance distance between it and the Taycan. The electric Macan will be offered with a variety of power outputs beneath this level, but the two most powerful versions will be badged Turbo and Turbo S, as with the Taycan.
Besides offering excellent on-road handling, the high degree of precision provided by electronic control of the motors and the wheels should enable the Macan EV to be very effective off road.
Meschke, meanwhile, predicts that Porsche may make the current lithium ion batteries 20-25% more efficient but “the next big step is solidstate” batteries, which for the same output as today’s could be half the weight. However, these are “five to seven years from industrialisation”.
