Porsche has extended its largest SUV family with a purely battery-electric variant, and the S Coupé tested here sits in the middle of that line-up. After the world premiere in November 2025, series production of the Cayenne Electric began in Bratislava at the start of February 2026. The S Coupé joined the base and Turbo models in March 2026, and it is this mid-range drivetrain that formed the subject of a detailed driving report.
Positioning within the electric Cayenne range
With up to 400 kW in normal driving and 490 kW with Launch Control, the S sits between the base model at 300 kW (325 kW with Launch Control) and the Turbo at 630 kW (850 kW with Launch Control). Porsche quotes 3.8 seconds from 0 to 100 km/h for the S and a 250 km/h top speed, against 4.8 seconds and 230 km/h for the base car and 2.5 seconds and 260 km/h for the Turbo. Even the entry version would be ample for everyday driving, the report notes.
A PPE that has been reworked for the larger model
The Cayenne uses the same Premium Platform Electric (PPE) as the Macan, but Porsche redeveloped two central components beyond the Macan's capability. The battery is more deeply integrated into the vehicle structure, and the S variant carries an oil-direct-cooled rear-axle motor, while the optional Porsche Active Ride adaptive suspension is used here in an SUV for the first time.
Both axles use permanently excited synchronous machines. The front motor is essentially derived from the Macan, whereas the rear unit is a specially developed, oil-direct-cooled machine reserved for the S and Turbo; the base model uses a water-cooled drive at the rear. Porsche obtains the Turbo's extra output not from a different motor but from a longer version of the same design, so the S receives the shorter unit and the Turbo the longer one.
In the oil cooling, an electrically non-conductive oil draws heat directly from the copper windings, whereas conventional water-jacket cooling must first move heat to an outer jacket. Porsche states the motor efficiency reaches up to 98 per cent and cites this more efficient cooling as one reason why the S achieves a slightly higher range than the base model despite its greater power.
Driving a 2,560-kilogram coupé
On the road, the S accelerates smoothly and forcefully without Launch Control, and the instantly available torque makes overtaking effortless. Even with repeated full-throttle bursts, propulsion remained consistent, with no early power cut-off observed during the test.
The data sheet lists a kerb weight of 2,560 kilograms for the standard S Coupé, so the suspension must manage that mass in corners, under braking and on poor surfaces. Adaptive air suspension with electronic damper control is standard. The test car also had Porsche Active Ride, a €8,324 option whose active dampers connect to a motor-pump unit on each axle and generate targeted forces at each wheel without mechanical stabilisers.
Behaviour depends heavily on the selected mode. In Comfort the Cayenne absorbs rough unevenness and, when cornering, leans slightly into the curve rather than outward — an unusual sensation that relieves occupants. Sport and Sport Plus keep the body flat without becoming uncomfortably hard. With precise steering and rear-axle steering, the S feels more agile than its size and weight suggest, although the mass cannot be fully masked; pushed too far, it understeers out of a curve, and the 22-inch wheels pass short, sharp edges into the cabin. Normal mode offers a good compromise.
Deceleration blends regenerative braking into the brake pedal, with the friction brake supplementing it as needed and an almost imperceptible transition. The ceramic brake system on the test car, with black callipers, adds €10,100 but is not required for everyday energy recovery. Rear-axle steering, at just under €1,700, is described as highly recommended: it shrinks the turning circle from 12.7 to 11.6 metres, a real everyday advantage for a car almost five metres long.
Battery, cooling and preconditioning
The drivetrain draws on a battery with 113 kWh gross and around 108 kWh usable energy. Porsche uses six modules with a total of 192 pouch cells, a cell format change from the Macan's prismatic cells. The chemistry is also new: a nickel-rich NMCA cathode with around 86 per cent nickel and an anode containing six per cent silicon raise energy density by roughly seven per cent versus the previous NMC-811 chemistry. The pack therefore holds eight kilowatt-hours more than the Taycan's and is around 103 litres more compact.
The silicon in the anode also improves fast-charging capability, but full charging power is available only within the correct battery temperature window, and pre-conditioning is needed to reach it quickly. Two cooling plates per module heat or cool the cells from above and below; Porsche says the pressure fans used for this require about 15 per cent less energy than conventional suction fans. Pre-conditioning is triggered automatically through the Charging Planner once a charging stop is set as a navigation destination, with no manual option otherwise — so a spontaneous arrival at a fast charger cannot specifically pre-heat the battery.
Charging performance in practice
Porsche shapes the charging curve to peak early: more than 300 kW is available from roughly five per cent state of charge (SoC), with the theoretical maximum around 55 per cent. In the recorded session 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, rising to a maximum of 386 kW at 44 per cent. The data sheet figure of 390 kW was not quite reached, which the report attributes to the charger rather than the car: Porsche provides 390 kW only above 520 amps, while the HyperCharger delivers a maximum of 500. For 400 kW, Porsche specifies an even narrower window — above 850 volts, a battery temperature of 40 to 42 degrees and an SoC of 45 to 48 per cent.
What matters most for a short stop is the remaining time to 80 per cent. After the first power drop, the Cayenne continues at around 290 kW; between roughly 60 and 71 per cent it holds about 270 kW, and at 80 per cent it is still at 183 kW. From 10 to 80 per cent took around 16 minutes by the author's timer, matching the configuration figure.
A downside appeared during the first fast-charging session: the cooling fans are noticeably loud during charging and briefly afterwards. A second session used Porsche's Quiet Charging mode, which can only be activated manually via the display after charging has started and reduces fan speed only, lowering cooling performance so the battery heats faster and must reduce charging power earlier. In the comparison, the car was noticeably quieter but the same 10 to 80 per cent charge still took 16 minutes, with a peak of 385 kW; the high plateau ended at 42 per cent, so at 44 per cent Quiet mode delivered 325 kW against 386 kW in Normal mode. Porsche says performance only drops under high starting battery and ambient temperatures — for example, from 10 to 80 per cent with a 35-degree battery and 45-degree ambient, charging can be extended by about one minute — and that a general statement is impossible given the many parameters.
For longer parking, an optional 22 kW AC charger at €1,666 cuts the specified 0 to 100 per cent time from 11 to 5.8 hours; 11 kW is standard. Since the model-year change in September 2026, inductive charging has also been orderable, with Porsche Wireless Charging rated at 11 kW and about 90 per cent efficiency for a €5,117 outlay.
Range, efficiency and everyday usability
For the specific configuration, Porsche quotes a combined WLTP range of 616 kilometres, while the S Coupé model range reaches up to 669 kilometres and the S with SUV bodywork up to 653 kilometres. Among Coupé variants, that is the highest value: the base model reaches up to 661 kilometres, the Turbo 637 kilometres.
On mixed city, country-road and motorway routes, consumption varied between around 20 and 27 kWh/100 km depending on speed. Gentle driving approached 20 kWh, mixed everyday driving settled near 24 kWh/100 km, and higher motorway speeds came in just under 27 kWh/100 km. With about 108 kWh usable, 24 kWh/100 km corresponds theoretically to roughly 450 kilometres on a full charge, or around 315 kilometres using the 80 to 10 per cent window. These onboard figures are not directly comparable with WLTP consumption, which also includes charging losses.
Inside, the infotainment runs through the curved Flow Display, and the test car added a passenger display and an augmented-reality head-up display. A separate control strip gives direct access to volume and climate. Not everything convinced: some functions are buried in submenus and the navigation map occasionally moves abruptly. The optional surface heating at €934, which warms armrests and door panels, was well received. The Coupé's flatter roofline slightly reduces practicality versus the SUV, with 534 to 1,347 litres of luggage space plus 90 litres in the frunk; only the Turbo has less, at 500 litres. Rear headroom is tighter but still sufficient. All three electric Cayenne variants tow up to 3 tonnes braked as standard, rising to 3.5 tonnes with the €2,492 Off-Road Package.
Price, options and the wider competitive picture
The S Coupé starts at €130,300. In the tested configuration, €69,440 of options brought the price to €199,740. Active Ride, the ceramic brake system with black callipers and the lightweight sport package alone accounted for €34,589. The report argues that a test car climbing this far above the base price is less an exception than a rule at Porsche, where a relatively modest entry price meets a long, costly options list.
That matters for evaluation: the driving experience with active suspension and rear-axle steering cannot be transferred directly to a standard base S, whereas the large battery and high DC charging power are part of the basic technical offering. In competition, the S faces the BMW iX5, the Mercedes EQS SUV and the Audi SQ8 e-tron, while the more closely related Audi Q6 e-tron and Porsche's own Macan Electric rank one class below. The report concludes that the further-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 feature rather than a performance one under the conditions tested. Sovereign propulsion and a surprisingly versatile chassis are offset by weight, operation and price.
