Introduction
Porsche has expanded its largest SUV range with a fully electric model, the Cayenne Electric. After its world premiere in November 2025, series production began in Bratislava in early February 2026. The lineup initially included base and Turbo versions; in March this year Porsche added an S variant in Coupé form. This test focuses on that mid-range S Coupé, assessing how far Porsche has developed the Premium Platform Electric (PPE) for this application and why charging noise deserves attention.
Powertrain and platform
The S Coupé delivers up to 400 kW in normal driving and 490 kW with Launch Control. It sits between the base model (300 kW, or 325 kW with Launch Control) and the Turbo (630 kW, or 850 kW with Launch Control). With Launch Control, the S is quoted to accelerate from 0 to 100 km/h in 3.8 seconds and reach 250 km/h. The base model takes 4.8 seconds and tops out at 230 km/h, while the Turbo takes 2.5 seconds and reaches 260 km/h. Even the base version would be more than adequate for everyday driving and brisk motorway journeys.
The Cayenne uses the same PPE as the Macan, but Porsche completely redeveloped two central components for the larger SUV. The battery is more deeply integrated into the vehicle structure, and the S variant features an oil-direct-cooled rear axle motor. The optional Porsche Active Ride adaptive suspension is used here for the first time in an SUV. Both axles employ permanently excited synchronous machines. The front motor is essentially derived from the Macan, while the rear axle has a specially developed oil-direct-cooled unit exclusive to S and Turbo models. The base model uses a water-cooled drive. The Turbo's extra power comes from a longer version of the same motor design, while the S uses the shorter one. An electrically non-conductive oil draws heat directly from the copper windings, unlike conventional water-jacket cooling. Porsche states motor efficiency is up to 98 per cent, and the more efficient cooling is cited as one reason the S achieves slightly higher range than the base model despite its greater power.
Chassis and driving dynamics
On the road, the S accelerates smoothly and forcefully without needing Launch Control. Instantly available torque makes overtaking effortless, and repeated full-throttle bursts do not cause an early power cut-off. However, the standard S Coupé has a kerb weight of 2,560 kilograms. As standard, an adaptive air suspension with electronic damper control manages this mass. The test vehicle also had Porsche Active Ride, costing an additional €8,324. Its active dampers connect to a motor-pump unit on each axle and generate targeted forces at each wheel without mechanical stabilisers. In Comfort mode, the system can even overcompensate for roll and pitch movements to reduce the forces acting on occupants; the Cayenne irons out rough unevenness and, when cornering, does not lean outward but slightly into the curve. Sport or Sport Plus keeps the body remarkably flat without the tuning becoming uncomfortably hard. Combined with precise steering and rear-axle steering, the S feels more agile than expected for its size and weight. Normal mode offers a good compromise. Still, the weight cannot be completely masked; if pushed too far, the S understeers out of the curve, and the 22-inch wheels transmit short, sharp edges unfiltered into the cabin.
Porsche integrates regenerative braking into the brake pedal, with the friction brake supplementing it as needed; the transition is almost imperceptible. The ceramic brake system fitted to the test vehicle costs €10,100, but this extra is not a prerequisite for everyday energy recovery. Rear-axle steering, on the other hand, is highly recommended and costs just under €1,700. It shrinks the turning circle from 12.7 to 11.6 metres—a real everyday advantage for a car almost five metres long.
Battery and charging
The drivetrain is powered by a battery with a gross energy content of 113 kWh, of which around 108 kWh is usable. Porsche uses six modules with a total of 192 pouch cells, changing the cell format compared with 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 increase energy density by about seven per cent compared to the previous NMC-811 chemistry. As a result, the storage system 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.
Full charging power is only available when the battery is within the correct temperature window, and pre-conditioning can bring it there quickly. Pre-conditioning is triggered automatically via the Charging Planner as soon as a charging stop is set as a navigation destination; Porsche does not otherwise provide a manual option. Anyone who drives to a fast charger spontaneously and without route guidance cannot specifically pre-heat the battery.
Once in the window, the Cayenne maintains its high pace over much of the charging process. The charging curve is designed to peak early: over 300 kW is available from around five per cent state of charge (SoC). In the test at an EnBW HyperCharger, the recording started at 9 per cent SoC and reached a maximum of 386 kW at 44 per cent. The full 390 kW from the data sheet was just short, and this was due to the charger, not the car: Porsche only provides 390 kW from over 520 amps, but the HyperCharger delivers a maximum of 500. From 10 to 80 per cent took around 16 minutes—exactly as specified in the configuration. This is a figure that stands out in this class.
One downside became apparent during the first fast-charging session: the cooling fans are noticeably loud during fast charging and for a short time afterwards. A second charging session was therefore recorded with Quiet Charging at the same charger on another day. This special mode can only be activated manually via the display after charging has started. It exclusively reduces fan speed, which lowers cooling performance and causes the battery to heat up faster; only when it reaches its limit temperature earlier does the vehicle adjust charging power, as Porsche explained. In the comparison, the car was noticeably quieter, but the same charge from 10 to 80 per cent still took just 16 minutes. The peak was almost identical at 385 kW. However, this cannot be generalised from a single measurement: there was only one run each. Quiet Charging is primarily intended to reduce noise. Porsche said that under moderate conditions, only the volume actually decreases. A noticeable reduction in performance only occurs at high starting battery and ambient temperatures.
Efficiency and range
For the specific configuration, Porsche states a combined WLTP range of 616 kilometres, although the S Coupé model range extends up to 669 kilometres, while the S with SUV bodywork achieves up to 653 kilometres. Among the Coupé variants, this is the highest value: the base model achieves up to 661 kilometres, while the Turbo manages 637 kilometres. On mixed routes of city, country roads and motorways, consumption varied between around 20 and 27 kWh/100 km depending on speed. In everyday mixed driving, the display settled around 24 kWh/100 km, and at higher motorway speeds it was just under 27 kWh/100 km. With around 108 kWh of usable battery capacity, 24 kWh/100 km theoretically equates to about 450 kilometres on a full charge. If the window between 80 and 10 per cent is used on a journey, around 315 kilometres can be covered under the same assumptions.
Interior, practicality and pricing
The cockpit offers comfortable seating and adequate space up front. Infotainment is operated via the curved Flow Display. The test vehicle also included a passenger display and a head-up display with augmented reality. A separate control strip provides direct access to volume and climate settings. While the hardware is well thought out, not everything about the operation convinced: some functions are buried in submenus, and the navigation map sometimes moves abruptly. The optional surface heating, at an additional €934, heats the armrests and door panels. Despite the spacious interior, the Coupé's flatter roofline slightly reduces practicality compared to the SUV. The luggage compartment holds 534 to 1,347 litres, plus 90 litres in the frunk. As standard, all three electric Cayenne variants can tow up to 3 tonnes when braked; with the optional Off-Road Package (€2,492), towing capacity increases to up to 3.5 tonnes.
The S Coupé starts at €130,300. In the current configuration, €69,440 worth of optional extras were added, bringing the test vehicle's price to €199,740. Active Ride, the ceramic brake system with black callipers, and the lightweight sport package alone cost a total of €34,589. At Porsche, a test vehicle climbing this far above the base price is less an exception than a rule. A relatively modest entry price meets a long, high-priced options list, and expensive extras with low production costs are particularly profitable. Substantive features like Active Ride are the exception.
This is crucial for evaluation: the driving experience with active suspension and rear-axle steering cannot be directly transferred to a standard base S. However, the large battery and high DC charging power are already part of the basic technical offering. Anyone who primarily wants to travel quickly and drive a Porsche does not need to exhaust the entire options list. The progress of the further developed PPE is most convincing at the fast charger. Here, the Cayenne S Coupé Electric turns data sheet values into reliable real-world performance: 386 kW at peak, around 16 minutes from 10 to 80 per cent. Quiet Charging remains a comfort feature, not a performance one—at least not under the conditions encountered. On the road, the S combines sovereign propulsion with a surprisingly versatile suspension. Weight, operation and price remain noticeable counterarguments. As the mid-range drivetrain variant, the S need not shy away from comparison with the Turbo. In competition, the S faces the BMW iX5, Mercedes EQS SUV or Audi SQ8 e-tron, while the more closely related Audi Q6 e-tron and Porsche's own Macan Electric rank one class below. Porsche sells to a wealthy, brand-loyal clientele that consciously and lavishly configures its vehicles, and the electric Cayenne is tailored precisely to this audience. For this customer base, a test vehicle costing almost €200,000 is not a surprise but the norm.
