Porsche's battery-electric Cayenne now spans three drivetrain tiers, and the S Coupé tested here sits between the base model and the Turbo. Porsche quotes up to 400 kW in normal driving and 490 kW with Launch Control for the S, enough for a claimed 0 to 100 km/h in 3.8 seconds and a 250 km/h top speed; the base model is said to take 4.8 seconds and reach 230 km/h, the Turbo 2.5 seconds and 260 km/h. The Cayenne Electric premiered in November 2025, series production began in Bratislava in early February 2026, and the S Coupé joined the range in March 2026.
The Cayenne shares the Premium Platform Electric (PPE) with the Macan, but Porsche redeveloped two central components beyond the Macan's capabilities: the battery is more deeply integrated into the vehicle structure, and the S uses an oil-direct-cooled rear axle motor. The optional Porsche Active Ride adaptive suspension appears here for the first time in an SUV. Both axles use permanently excited synchronous machines, with the front motor essentially derived from the Macan, while the rear axle carries an oil-direct-cooled unit reserved for the S and Turbo, the base model using water cooling. Porsche produces the Turbo's extra output not with a different motor but with a longer version of the same design, the S taking the shorter one. In that unit an electrically non-conductive oil draws heat directly from the copper windings, whereas conventional water-jacket cooling must first move heat to the outer jacket; Porsche states motor efficiency of up to 98 per cent and cites this cooling as one reason the S achieves a slightly higher range than the base model despite its greater power.
The battery has a gross capacity of 113 kWh, of which roughly 108 kWh is usable, in six modules with 192 pouch cells — a change of cell format from the Macan's prismatic cells. A nickel-rich NMCA cathode of about 86 per cent nickel and an anode with six per cent silicon raise energy density by roughly seven per cent versus the previous NMC-811 chemistry. The pack holds eight kilowatt-hours more than the Taycan's yet is around 103 litres more compact, and the silicon also aids fast charging. Two cooling plates per module heat or cool the cells from above and below, and Porsche says the pressure fans use about 15 per cent less energy than conventional suction fans. Pre-conditioning runs automatically through the Charging Planner once a charging stop is set as a navigation destination, with no manual option, so a driver arriving spontaneously cannot specifically pre-heat the battery; the driver display shows whether the battery is in its temperature window.
Porsche designs the charging curve to peak early, with more than 300 kW available from roughly five per cent state of charge (SoC) and a theoretical maximum around 55 per cent. In a recording at an EnBW HyperCharger starting at nine per cent SoC, 333 kW was available at 12 per cent and around 360 kW from 13 per cent, climbing to a maximum of 386 kW at 44 per cent. The 390 kW on the data sheet was narrowly missed, which the report attributes to the charger rather than the car: Porsche provides 390 kW only above 520 amps, while the HyperCharger supplies a maximum of 500. For 400 kW, Porsche specifies more than 850 volts, a battery temperature of 40 to 42 degrees Celsius and an SoC of 45 to 48 per cent.
After the first drop in power the Cayenne continued at around 290 kW, held roughly 270 kW between about 60 and 71 per cent, and still drew 183 kW at 80 per cent. From 10 to 80 per cent the stop took about 16 minutes, matching the configuration figure. One caveat surfaced: the cooling fans were noticeably loud during fast charging and for a short time afterwards. Porsche's Quiet Charging mode, which can only be activated manually via the display after charging starts, lowers fan speed, reduces cooling and lets the battery heat up faster; only when it reaches its limit temperature earlier must the vehicle adjust power. In a second session at the same charger the car was noticeably quieter and the 10 to 80 per cent stop still took just 16 minutes, with a near-identical peak of 385 kW, though in Quiet mode the high plateau ended at 42 per cent, giving 325 kW at 44 per cent against 386 kW in Normal mode. The report cautions against generalising from one measurement each; Porsche says that under moderate conditions only the volume falls, and that a noticeable performance reduction occurs only at high starting battery and ambient temperatures, for example extending a 10 to 80 per cent stop by about one minute.
On the road the S accelerates smoothly and forcefully without Launch Control, with instantly available torque and consistent propulsion under repeated full-throttle bursts; the reviewer experienced no early power cut-off. 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 at €8,324, whose dampers connect to a motor-pump unit on each axle and generate targeted forces at each wheel without mechanical stabilisers. Comfort mode irons out rough unevenness and, when cornering, leans slightly into the curve rather than outward; Sport and Sport Plus keep the body flat without becoming uncomfortably hard. Rear-axle steering, at just under €1,700, shrinks the turning circle from 12.7 to 11.6 metres. The weight cannot be fully masked, though: pushed too far the S understeers out of a curve, and the 22-inch wheels transmit sharp edges into the cabin. Regenerative braking is integrated into the brake pedal with the friction brake supplementing it almost imperceptibly; the ceramic system on the test car costs €10,100.
For the tested configuration, Porsche quotes a combined WLTP range of 616 kilometres. The S Coupé line reaches up to 669 kilometres — the highest among Coupé variants, ahead of the base Coupé at up to 661 kilometres and the Turbo at up to 637 — while the S with SUV bodywork reaches up to 653 kilometres. Consumption on mixed city, country-road and motorway routes ranged from about 20 to 27 kWh/100 km, settling around 24 kWh/100 km in everyday mixed driving. With roughly 108 kWh usable, that implies about 450 kilometres on a full charge, or around 315 kilometres using the 80 to 10 per cent window. On-board figures are not directly comparable with WLTP consumption, which also includes charging losses.
Inside, the curved Flow Display handles infotainment; the test car added a passenger display and an augmented-reality head-up display, while a control strip gives direct access to volume and climate. Some functions are buried in submenus and the navigation map occasionally moves abruptly. Optional surface heating at €934 warms the armrests and door panels. The Coupé's flatter roofline slightly reduces practicality versus the SUV: the luggage compartment holds 534 to 1,347 litres plus a 90-litre front boot, and all three variants tow up to 3 tonnes braked, rising to 3.5 tonnes with the €2,492 Off-Road Package. A 22 kW AC charger at €1,666 cuts a 0 to 100 per cent charge from 11 to 5.8 hours, and since the September 2026 model-year change an 11 kW inductive Porsche Wireless Charging system has been orderable at €5,117.
The S Coupé starts at €130,300, but €69,440 of options took the test car to €199,740, with Active Ride, the ceramic brakes and the lightweight sport package accounting for €34,589. Porsche's options list is generally extensive and costly, and the report argues that features such as Active Ride are the substantive exceptions. A key point for buyers is that the active suspension and rear-axle steering experience cannot be transferred to a standard base S, whereas the large battery and high DC charging power are part of the basic technical package. 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 ranked a class below.
Overall, the reworked PPE is most convincing at the fast charger, where data-sheet values become reliable real-world performance, and Quiet Charging remains a comfort rather than a performance feature under the conditions described. On the road the S combines sovereign propulsion with a surprisingly versatile chassis, while weight, operation and price remain counterarguments. As the mid-range drivetrain variant it need not shy away from comparison with the Turbo, and the near-€200,000 test car shows how far a single model position can diverge from a modestly equipped car through options. Porsche is selling to a wealthy, brand-loyal clientele that configures its cars deliberately, and the electric Cayenne is tailored to that audience.
