Porsche's electric Cayenne range now spans three drivetrain tiers, with the S Coupé tested here in the middle. The mid-range variant delivers up to 400 kW in normal driving and 490 kW with Launch Control, against 300 kW (325 kW with Launch Control) for the base model and 630 kW (850 kW with Launch Control) for the Turbo. Porsche quotes 3.8 seconds from 0 to 100 km/h with Launch Control and a 250 km/h top speed for the S, compared with 4.8 seconds and 230 km/h for the base car and 2.5 seconds and 260 km/h for the Turbo.
The Cayenne joined Porsche's largest SUV line as a purely battery-electric model. After a world premiere in November 2025, series production began in Bratislava at the start of February 2026, and the S in Coupé form followed in March 2026.
A reworked PPE, not just a stretched Macan
The Cayenne uses the Premium Platform Electric (PPE) shared 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 variant uses an oil-direct-cooled rear-axle motor.
Both axles carry permanently excited synchronous machines. The front motor is essentially derived from the Macan, while the rear axle uses a specially developed, oil-direct-cooled unit reserved for the S and Turbo; the base model relies on a water-cooled drive. Porsche obtains the Turbo's extra output through a longer version of the same design — the S takes the shorter one.
In the oil-cooled design, 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 motor efficiency reaches up to 98 per cent and cites the more efficient cooling as one reason the S achieves a slightly higher range than the base model despite its greater power.
Charging is where the platform's progress shows
The battery has a gross energy content of 113 kWh, of which around 108 kWh is usable. Porsche uses six modules with 192 pouch cells, a change from the Macan's prismatic cells. The chemistry is also new: 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 over NMC-811, the company says, giving eight kilowatt-hours more storage than the Taycan while being around 103 litres more compact. Two cooling plates per module heat or cool the cells from above and below.
Full charging power is available only inside the correct battery temperature window, and pre-conditioning can bring the pack there. It is triggered automatically via the Charging Planner once a charging stop is set as a navigation destination; Porsche offers no manual option, so a spontaneous stop without route guidance cannot specifically pre-heat the battery.
In the test the charging curve peaked early. From nine per cent state of charge at an EnBW HyperCharger, the car drew 333 kW at 12 per cent and around 360 kW from 13 per cent, rising to a maximum of 386 kW at 44 per cent. The full 390 kW on the data sheet was narrowly missed, which the report attributes to the charger rather than the car: Porsche supplies 390 kW only above 520 amps, while the HyperCharger delivers a maximum of 500.
What matters for a short break is the run to 80 per cent. After the first power drop, the Cayenne continued at around 290 kW, held roughly 270 kW between about 60 and 71 per cent, and was still at 183 kW at 80 per cent. The 10 to 80 per cent charge took around 16 minutes, matching Porsche's specification.
Quiet Charging: a comfort feature, not a performance one
The cooling fans were noticeably loud during fast charging and briefly afterwards. Porsche's Quiet Charging mode, which can only be activated manually via the display after charging has started, reduces fan speed, lowering cooling performance so the battery heats faster; the vehicle then has to reduce charging power only once the pack reaches its limit temperature.
In a second comparison session at the same charger, the car was noticeably quieter and still took 16 minutes from 10 to 80 per cent, with a peak of 385 kW. The high plateau in Quiet mode ended earlier, at 42 per cent, so at 44 per cent the car drew 325 kW in Quiet mode against 386 kW in Normal mode. The report cautions that a single run each cannot be generalised and that Quiet Charging is primarily meant to cut noise; Porsche says a noticeable performance reduction occurs only at high starting battery and ambient temperatures.
For longer parking, an optional 22 kW AC charger costing €1,666 cuts the specified 0 to 100 per cent time from 11 to 5.8 hours; 11 kW is standard. Since the September 2026 model-year change, Porsche Wireless Charging at 11 kW and around 90 per cent efficiency can be ordered regularly, at €5,117.
Chassis, driving and efficiency
The S Coupé carries a kerb weight of 2,560 kilograms. Standard equipment is an adaptive air suspension with electronic damper control; the test car added Porsche Active Ride at €8,324. Its active dampers connect to a motor-pump unit on each axle and generate targeted forces at each wheel without mechanical stabilisers, stabilising the body under dynamic driving; in Comfort mode the system can overcompensate for roll and pitch to reduce the forces on occupants.
Behaviour depends heavily on the mode. In Comfort, the Cayenne smooths rough unevenness and leans slightly into a curve rather than outward. Sport and Sport Plus keep the body flat without becoming uncomfortably hard, and with precise steering and rear-axle steering the S feels more agile than its size and weight suggest. The weight cannot be completely masked, however: pushed too far, the S understeers out of a curve, and the 22-inch wheels transmit short, sharp edges unfiltered.
Regenerative braking is integrated into the brake pedal, with the friction brake supplementing as needed and an almost imperceptible transition. The ceramic brake system on the test car, with black callipers, costs €10,100 but is not a prerequisite for everyday energy recovery. Rear-axle steering, at just under €1,700, shrinks the turning circle from 12.7 to 11.6 metres.
Porsche quotes a combined WLTP range of 616 kilometres for the tested configuration, while the S Coupé line reaches up to 669 kilometres and the Turbo 637 kilometres. On mixed city, country and motorway routes, consumption varied between around 20 and 27 kWh/100 km, settling around 24 kWh/100 km in everyday mixed driving. With around 108 kWh usable, that theoretically equates to about 450 kilometres on a full charge, or roughly 315 kilometres using the 80 to 10 per cent window.
The Coupé's flatter roofline slightly reduces practicality against the SUV: the luggage compartment holds 534 to 1,347 litres plus 90 litres in the frunk, and rear headroom is tighter but still sufficient. All three electric Cayenne variants can tow up to 3 tonnes when braked, rising to up to 3.5 tonnes with the optional Off-Road Package at €2,492.
The options list and the value question
The S Coupé starts at €130,300, but the test car's €69,440 of options brought its price to €199,740; Active Ride, the ceramic brake system and the lightweight sport package alone totalled €34,589. The review's assessment is that 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 technical offering.
In competition, the S faces the BMW iX5, the Mercedes EQS SUV and the Audi SQ8 e-tron, with the more closely related Audi Q6 e-tron and Porsche's own Macan Electric a class below. The conclusion is that the S need not shy away from comparison with the Turbo, and that the almost €200,000 test car mainly shows how far one position in the range can diverge through options — aimed at a wealthy, brand-loyal clientele that configures its cars lavishly.
