Porsche's largest SUV range now includes a purely battery-electric variant, the Cayenne Electric, built on the Premium Platform Electric (PPE) that also underpins the Macan. Following its world premiere in November 2025, series production began in Bratislava at the start of February 2026, and in March the company added an S variant in Coupé form — the version examined in this test.
Powertrain and the reworked PPE
With up to 400 kW in normal driving and 490 kW with Launch Control, the S sits between the 300 kW base model (325 kW with Launch Control) and the 630 kW Turbo (850 kW with Launch Control). Porsche quotes 3.8 seconds from 0 to 100 km/h and a 250 km/h top speed for the S, against 4.8 seconds and 230 km/h for the base model and 2.5 seconds and 260 km/h for the Turbo.
Although the Cayenne shares the PPE foundation with the Macan, Porsche redeveloped two central components for its larger SUV. 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, with the front motor essentially derived from the Macan. The rear unit is a specially developed, oil-direct-cooled machine exclusive to the S and Turbo; the base model relies on water cooling. Porsche obtains the Turbo's additional output not through a different motor but through a longer version of the same design — the S gets the shorter one.
An electrically non-conductive oil draws heat directly from the copper windings, whereas conventional water-jacket cooling must first carry 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 the S achieves a slightly higher range than the base model despite its greater power.
Chassis and control
The drivetrain has to move a substantial mass: the standard S Coupé has a kerb weight of 2,560 kilograms. Adaptive air suspension with electronic damper control is standard, while the test car added Porsche Active Ride for 8,324 euros. Its active dampers are linked to a motor-pump unit on each axle and generate targeted forces at each wheel without mechanical stabilisers. In Comfort mode the system can overcompensate for roll and pitch to reduce the forces acting on occupants, while Sport and Sport Plus keep the body flat without becoming harsh. Rear-axle steering, a 1,700-euro option, cuts the turning circle from 12.7 to 11.6 metres. Regenerative braking is integrated into the brake pedal, with friction braking supplementing it as needed; the ceramic system fitted to the test car costs 10,100 euros.
Battery and charging behaviour
The battery has a gross energy content of 113 kWh, of which around 108 kWh is usable, arranged in six modules with 192 pouch cells. The cell format changes from the Macan's prismatic cells, and the chemistry is new: a nickel-rich NMCA cathode with around 86 per cent nickel and an anode with six per cent silicon raise energy density by about seven per cent compared with NMC-811. Porsche says the pack holds eight kilowatt-hours more than the Taycan's yet is around 103 litres more compact. Two cooling plates per module heat or cool the cells from above and below, and Porsche notes that the pressure fans used require roughly 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; there is no manual option to start it. In the test at an EnBW HyperCharger, charging began at 9 per cent state of charge, delivering 333 kW at 12 per cent and around 360 kW from 13 per cent, and reaching a maximum of 386 kW at 44 per cent. The full 390 kW from the data sheet was narrowly missed because of 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 and a state of charge of 45 to 48 per cent. From 10 to 80 per cent the Cayenne took around 16 minutes by the tester's timer, matching the configuration figure.
Quiet Charging and its limits
During the first fast-charging session the cooling fans were noticeably loud, and for a short time afterwards. Porsche offers a Quiet Charging mode, activated manually via the display after charging has started, which reduces fan speed only. This lowers cooling performance and lets the battery heat faster; the vehicle then has to adjust charging power earlier. In a second session the car was noticeably quieter, but 10 to 80 per cent still took 16 minutes and the peak was almost identical at 385 kW. The curves were not identical, however: in Quiet mode 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 stresses that the mode is intended primarily to reduce noise, and that under moderate conditions only the volume decreases. The outside temperature during the test was around 20 degrees; a noticeable reduction in performance occurs only at high starting battery and ambient temperatures. As an example, the manufacturer cites a 10 to 80 per cent session starting at a battery temperature of 35 degrees and an ambient temperature of 45 degrees, where charging time can be extended by around one minute. A general statement is impossible because of the many parameters involved.
For longer parking periods, the optional 22 kW AC charger costs 1,666 euros and reduces the specified 0 to 100 per cent charging time from 11 to 5.8 hours; 11 kW is standard. Since the model-year change in September 2026, inductive charging has also been available to order: Porsche Wireless Charging offers 11 kW at around 90 per cent efficiency for 5,117 euros.
Consumption and range
Porsche states a combined WLTP range of 616 kilometres for the tested configuration, though the S Coupé model range extends up to 669 kilometres and the S with SUV bodywork reaches up to 653 kilometres. Among the Coupé variants, the S Coupé's 669 kilometres is the highest value; the base model manages up to 661 kilometres and the Turbo 637 kilometres. On mixed routes, consumption varied between around 20 and 27 kWh/100 km depending on speed, settling near 24 kWh/100 km in everyday mixed driving. With around 108 kWh usable, 24 kWh/100 km equates to about 450 kilometres on a full charge, or around 315 kilometres when using the 80 to 10 per cent window.
Interior, practicality and price
The cockpit is operated through a curved Flow Display, supplemented in the test car by a passenger display and a head-up display with augmented reality, plus a separate control strip for volume and climate. Optional surface heating at 934 euros warms the armrests and door panels. The Coupé's flatter roofline slightly reduces practicality compared with the SUV: luggage capacity is 534 to 1,347 litres plus 90 litres in the frunk, and rear headroom is a little tighter. All three electric Cayenne variants can tow up to 3 tonnes when braked, rising to 3.5 tonnes with the 2,492-euro Off-Road Package.
The S Coupé starts at 130,300 euros, but the test car's 69,440 euros of options brought the total to 199,740 euros; Active Ride, the ceramic brake system with black callipers and the lightweight sport package alone accounted for 34,589 euros. Porsche's pattern is a relatively modest entry price combined with a long, high-priced options list. This matters for evaluation: the driving experience with active suspension and rear-axle steering cannot be transferred directly to a standard S, whereas the large battery and high DC charging power are part of the basic technical offering.
Assessment
The reworked PPE is most convincing at the fast charger, where the Cayenne S Coupé Electric turns data-sheet values into reliable real-world performance: 386 kW at peak and around 16 minutes from 10 to 80 per cent. Quiet Charging remains a comfort feature rather than a performance one, at least under the conditions encountered, since the car charged significantly more quietly without extending the charging time. On the road, the S combines sovereign propulsion with a surprisingly versatile suspension, while weight, operation and price remain noticeable counterarguments. 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 ranked one class below.
