Porsche's battery-electric Cayenne line-up has grown in stages: after a world premiere in November 2025 and the start of series production in Bratislava in early February 2026, an S variant in Coupé form joined the range in March. Testing the mid-range model showed how far Porsche has developed the Premium Platform Electric (PPE) that also underpins the Macan.
The S sits between the base model and the Turbo. Porsche quotes up to 400 kW in normal driving and 490 kW with Launch Control, against 300 kW (325 kW with Launch Control) for the base and 630 kW (850 kW) for the Turbo. The S Coupé is claimed to reach 100 km/h from rest in 3.8 seconds and 250 km/h, while the base model takes 4.8 seconds and the Turbo 2.5 seconds.
A familiar platform, reworked in two key areas
The Cayenne shares the PPE with the Macan, but Porsche says it completely redeveloped two central components. The battery is more deeply integrated into the vehicle structure, and the S uses an oil-direct-cooled rear axle motor. Both axles employ permanently excited synchronous machines; the front motor is essentially derived from the Macan, while the rear unit is exclusive to the S and Turbo, with the base model relying on a water-cooled drive. The Turbo's extra output comes not from a different motor but from a longer version of the same design.
The cooling approach is central. Rather than a conventional water jacket that must first absorb heat at an outer surface, an electrically non-conductive oil draws heat directly from the copper windings. Porsche says this helps sustain performance under high load, gives the motor efficiency of up to 98 per cent, and explains why the S achieves a slightly higher range than the base model despite its greater power.
Charging: fast when conditions align
The drivetrain draws on a battery with 113 kWh gross and around 108 kWh usable energy, arranged in six modules with 192 pouch cells. The cell format differs from the Macan's prismatic cells, and the chemistry is new: a nickel-rich NMCA cathode with about 86 per cent nickel and an anode containing six per cent silicon raise energy density by roughly seven per cent over the earlier NMC-811 chemistry. Porsche says the pack holds eight kilowatt-hours more than the Taycan's and is about 103 litres more compact.
Silicon in the anode is also intended to improve fast charging, but full power is only available inside a defined temperature window, shown on the driver information display. Two cooling plates per module heat or cool the cells from above and below, and Porsche says the pressure fans need about 15 per cent less energy than conventional suction fans. Pre-conditioning is triggered automatically through the Charging Planner when a charging stop is set as a navigation destination, with no manual option — so a driver arriving spontaneously at a fast charger cannot specifically pre-heat the battery.
The charging curve peaks early, with more than 300 kW available from around five per cent state of charge (SoC) and the theoretical maximum at roughly 55 per cent. In the test, a session at an EnBW HyperCharger began at nine per cent SoC: 333 kW was available at 12 per cent and around 360 kW from 13 per cent, rising to a maximum of 386 kW at 44 per cent. The data sheet's 390 kW was just missed, which the author attributes to the charger rather than the car, since Porsche releases 390 kW only above 520 amps while the charger delivers a maximum of 500. Charging from 10 to 80 per cent took around 16 minutes, matching the configuration, with the car holding about 290 kW after the first drop in power.
Quiet Charging: comfort with boundaries
One drawback appeared during the first fast-charging session: the cooling fans are noticeably loud while charging and for a short time afterwards. Porsche offers a Quiet Charging mode that can only be activated manually on the display after charging has started. It reduces fan speed, which lowers cooling performance and lets the battery heat up faster; only when the limit temperature is reached earlier does the vehicle adjust charging power.
In the author's comparison the car was noticeably quieter, and the 10 to 80 per cent charge still took about 16 minutes with a peak of 385 kW. In Quiet mode the high plateau ended earlier, at 42 per cent. The author cautions that a single run each cannot be generalised, and Porsche says that under moderate conditions only the volume decreases; a noticeable performance reduction would occur mainly at high starting battery and ambient temperatures, which the manufacturer illustrates with a 10 to 80 per cent charge from a 35-degree battery temperature and a 45-degree ambient temperature where charging time could be extended by around one minute.
Chassis: masking weight, within limits
Acceleration is only part of the story, because the standard S Coupé has a kerb weight of 2,560 kilograms. Adaptive air suspension with electronic damper control is standard, and the test car added Porsche Active Ride for €8,324. Its active dampers are connected to a motor-pump unit on each axle and generate targeted forces at each wheel without mechanical stabilisers; in Comfort mode, Porsche says the system can even overcompensate for roll and pitch to reduce the forces on occupants.
In practice, the author found that the Cayenne irons out rough unevenness and leans slightly into a curve rather than outward, an unusual sensation that relieves occupants. Sport and Sport Plus keep the body flat without becoming uncomfortably hard, and rear-axle steering helps the S feel agile for its size. The weight cannot be fully masked, however: pushed hard, the car understeers out of a curve, and the 22-inch wheels transmit short, sharp edges into the cabin. The optional rear-axle steering, at just under €1,700, shrinks the turning circle from 12.7 to 11.6 metres. Regenerative braking is integrated into the brake pedal, with the friction brake supplementing it almost imperceptibly; the ceramic brakes on the test car cost €10,100.
Efficiency, equipment and price
Porsche states a combined WLTP range of 616 kilometres for the tested configuration, while the S Coupé range extends up to 669 kilometres and the S with SUV bodywork reaches up to 653 kilometres. Among Coupé variants that is the highest value, with the base model at up to 661 kilometres and the Turbo at 637 kilometres. On mixed routes, consumption varied between about 20 and 27 kWh/100 km; in everyday mixed driving the display settled around 24 kWh/100 km, which with around 108 kWh usable would equate to roughly 450 kilometres on a full charge, or around 315 kilometres using the 80 to 10 per cent window. The author notes these on-board figures are not directly comparable to WLTP values, which include charging losses.
The optional 22 kW AC charger at €1,666 cuts the specified 0 to 100 per cent time from 11 to 5.8 hours, with 11 kW standard; since the September 2026 model year change, 11 kW inductive charging at around 90 per cent efficiency is also available at €5,117. Inside, a curved Flow Display handles infotainment alongside an optional passenger display and an augmented-reality head-up display. Optional surface heating at €934 warms armrests and door panels. The Coupé's flatter roofline slightly reduces practicality: luggage capacity is 534 to 1,347 litres plus 90 litres in the front compartment, and all three electric variants can tow up to 3 tonnes when braked, rising to 3.5 tonnes with the €2,492 Off-Road Package.
The S Coupé starts at €130,300, and the test vehicle's €69,440 of options bring the price to €199,740; Active Ride, the ceramic brakes and the lightweight sport package alone account for €34,589. The author argues that a test car climbing so far above its base price is closer to the norm at Porsche. Crucially, the driving experience with active suspension and rear-axle steering cannot be transferred to a standard S, but the large battery and high DC charging power are already part of the basic technical offering. In competition, the S faces the BMW iX5, the Mercedes EQS SUV and the Audi SQ8 e-tron, with the Audi Q6 e-tron and Porsche's own Macan Electric a class below.
