The electric Macan is an important car for Porsche. Why? Because it’s the best-selling Porsche model, so it’s very important for the company to get the right EV version. That process is well underway, and while the new car won’t hit showrooms as soon as the company had hoped due to software issues, it should go on sale in 2024.
This week, Antoon Janssen, Porsche powertrain manager for the Macan line, said Coach that the Macan EV, based on the new Premium Platform Electric chassis, will be the sportiest car in its class. It will use a pair of permanently excited electric motors – one per axle – similar to those used in the Porsche Taycan, but heavily reworked to increase power density and efficiency.
The new motors feature a “double-V” magnet arrangement and switch from a silicon semiconductor to a silicon carbide, which reduces switching losses in the motors’ pulse inverters. The result is a combined output of 450 kW (603 hp) and 1000 Nm (738 lb ft) of torque delivered to all four wheels. Rear-wheel drive is also possible on the PPE platform, Janssen said, although this is initially only used to decouple the front engine when cruising to reduce rolling resistance (and save energy).
Dynamics was also a point of attention for the Macan EV. Model chassis manager Dominik Hartmann has confirmed that it will have a “performance rear axle”, with the engine mounted as far back as possible. This gives a weight distribution of 48% front and 52% rear to maximize traction.
The Macan EV will be the first model to receive Porsche-designed twin-valve dampers, which are said to improve ride comfort, as they allow independent adjustment via the Porsche Active Suspension Management (PASM) system. This will also allow the suspension to be lowered at certain speeds to improve the car’s aerodynamic profile and reduce energy consumption.
To improve handling, the maximum steering angle of the front wheels has been increased by 15% compared to the current Macan and rear wheel steering up to 5 degrees is available at speeds below 80 km/h. The more expensive versions of the Macan EV will also get a rear-axle-mounted electronic locking differential, designed to improve torque-vectoring capabilities.
Every Porsche Macan EV will come with a 100kWh battery, which Porsche says is the optimal size to minimize journey times. Using software built into the battery pack, the battery can be split into two 400-volt halves to reduce charging times.
Janssen has also confirmed that the PPE platform can be extended to accommodate more than 12 prismatic battery modules from the Macan. This suggests that the Porsche Cayenne EV, which would also use the PPE platform, could have a larger battery to compete with the Mercedes EQS SUV.
Porsche expects 80% of its sales to be electric vehicles by 2030, led by the Macan, and each will be true to the Porsche tradition of spirited performance with exceptional comfort. The company has come a long way from the original Mission E prototype that became the Taycan.
