Porsche has extended its largest SUV line with a purely battery-electric Cayenne, and the mid-range S in Coupé form is the version electrive put through its paces. The test examined how reliably the model's data-sheet figures — a 113 kWh gross battery, a rear-axle motor with oil-direct cooling and optional active suspension — translate into real driving and charging. The Cayenne Electric premiered in November 2025, series production began in Bratislava in early February 2026, and Porsche added the S in Coupé form in March 2026.
The S within the range
The S sits between the base model and the Turbo, delivering 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 with Launch Control) for the Turbo. With Launch Control, Porsche quotes 0 to 100 km/h in 3.8 seconds and a 250 km/h top speed for the S; the base takes 4.8 seconds and reaches 230 km/h, the Turbo 2.5 seconds and 260 km/h.
Drivetrain and chassis
The Cayenne uses the same Premium Platform Electric as the Macan, but Porsche redeveloped two central components. The battery is more deeply integrated into the vehicle structure, and the S has an oil-direct-cooled rear-axle motor. Both axles use 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 using a water-cooled drive. Porsche obtains the Turbo's extra output through a longer version of the same motor, not a different one.
In the oil-cooled motor, an electrically non-conductive oil draws heat directly from the copper windings, whereas conventional water-jacket cooling must first reach the outer jacket. Porsche states motor efficiency is up to 98 per cent and cites this more efficient cooling as one reason the S achieves a slightly higher range than the base model despite its greater power.
On the road, the test found the S accelerates smoothly and forcefully without Launch Control, with instantly available torque and consistent propulsion under repeated full-throttle bursts. Controlling the mass is a separate matter: the standard S Coupé weighs 2,560 kilograms. Adaptive air suspension with electronic damper control is standard, and the test car added Porsche Active Ride for €8,324, whose active dampers connect to a motor-pump unit on each axle and generate targeted forces without mechanical stabilisers. In Comfort mode the system can overcompensate for roll and pitch, so the body leans slightly into curves, while Sport and Sport Plus keep it flat without becoming harsh.
Regenerative braking is integrated into the brake pedal, with the friction brake supplementing it, and the transition is almost imperceptible. The ceramic brake system cost €10,100, and rear-axle steering, at just under €1,700, cuts the turning circle from 12.7 to 11.6 metres.
Battery and charging
The battery has a gross energy content of 113 kWh, around 108 kWh of it usable. Porsche uses six modules with 192 pouch cells, changing the cell format from the Macan's prismatic cells. A nickel-rich NMCA cathode (around 86 per cent nickel) and an anode with six per cent silicon raise energy density by about seven per cent versus the previous NMC-811 chemistry. The pack holds eight kilowatt-hours more than the Taycan's and is around 103 litres more compact.
Two cooling plates per module heat or cool the cells from above and below, and Porsche says the pressure fans require around 15 per cent less energy than conventional suction fans. Pre-conditioning is triggered automatically via the Charging Planner when a charging stop is set as a navigation destination, with no manual option, so a driver heading spontaneously to a fast charger cannot specifically pre-heat the battery.
At an EnBW HyperCharger, the test began charging at nine per cent state of charge (SoC). At 12 per cent, 333 kW was available; from 13 per cent, around 360 kW; power peaked at 386 kW at 44 per cent. The data-sheet figure of 390 kW was just missed, which the test attributes to the charger rather than the car: Porsche provides 390 kW only from over 520 amps, while the HyperCharger delivers a maximum of 500. For 400 kW, Porsche specifies over 850 volts, a battery temperature of 40 to 42 degrees and an SoC of 45 to 48 per cent. After the first power drop, charging continued at around 290 kW, held around 270 kW between roughly 60 and 71 per cent, and still delivered 183 kW at 80 per cent. From 10 to 80 per cent took around 16 minutes, matching the configuration figure.
Quiet Charging
One downside appeared in the first fast-charging session: the cooling fans are noticeably loud during fast charging and briefly afterwards. The test therefore recorded a second session using Quiet Charging, which can only be activated manually via the display after charging has started. It reduces fan speed, lowering cooling and causing the battery to heat faster; the vehicle then adjusts charging power once it reaches its limit temperature, as Porsche explained. The car was noticeably quieter, but the same 10 to 80 per cent charge still took 16 minutes, with a peak almost identical at 385 kW. In Quiet mode the high plateau ended at 42 per cent, showing 325 kW at 44 per cent against 386 kW in Normal mode. The test stresses that a single run each cannot be generalised: Quiet Charging is intended primarily to reduce noise, and a noticeable performance reduction occurs only at high starting battery and ambient temperatures — Porsche cites a session at 35 degrees starting battery temperature and 45 degrees ambient where charging time can be extended by around one minute.
Range, consumption and interior
For the specific configuration, Porsche states a combined WLTP range of 616 kilometres, with the S Coupé range extending up to 669 kilometres and the S SUV up to 653 kilometres. On mixed routes, consumption varied between around 20 and 27 kWh/100 km depending on speed, settling around 24 kWh/100 km in everyday mixed driving. With around 108 kWh usable, that equates theoretically to about 450 kilometres on a full charge, or around 315 kilometres using the 80 to 10 per cent window.
Inside, infotainment runs through the curved Flow Display; the test car added a passenger display, a head-up display with augmented reality and a control strip for volume and climate. The test found some functions buried in submenus and the navigation map occasionally moving abruptly, but praised the €934 surface heating. The Coupé's flatter roofline slightly reduces practicality: the luggage compartment holds 534 to 1,347 litres plus 90 litres in the frunk, and rear headroom is slightly tighter. All three electric variants tow up to 3 tonnes braked as standard, rising to 3.5 tonnes with the €2,492 Off-Road Package, while a 22 kW AC charger at €1,666 cuts 0 to 100 per cent charging from 11 to 5.8 hours and Porsche Wireless Charging at 11 kW has been orderable since the September 2026 model year change for €5,117.
Pricing and positioning
The S Coupé starts at €130,300, but the test car carried €69,440 of options, bringing its price to €199,740; Active Ride, the ceramic brakes and the lightweight sport package alone accounted for €34,589. The test notes that a test vehicle climbing this far above the base price is less an exception than a rule at Porsche, and argues the driving experience with active suspension and rear-axle steering cannot be directly transferred to a standard base S, whereas the large battery and high DC charging power are part of the basic offering.
In competition, the S faces the BMW iX5, the Mercedes EQS SUV and the Audi SQ8 e-tron. The test concludes that the developed PPE is most convincing at the fast charger, turning data-sheet values into reliable real-world performance, and that Quiet Charging remains a comfort rather than a performance feature under the conditions encountered, with weight, operation and price the noticeable counterarguments.
