A platform that has moved on
Porsche has expanded its largest SUV range with a fully battery-electric Cayenne, and the S Coupé tested here shows where the manufacturer has taken its Premium Platform Electric (PPE) beyond the Macan. After a world premiere in November 2025, series production started in Bratislava in early February 2026; the S Coupé joined the line-up in March 2026 and was the subject of the driving report. The test suggests the platform's progress is most convincing at the charging station, while weight and price remain the counterarguments.
Three power levels, one architecture
The S sits between the base model and the Turbo. It 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 and 630 kW (850 kW with Launch Control) for the Turbo. With Launch Control, Porsche quotes 3.8 seconds from 0 to 100 km/h and a 250 km/h top speed for the S; the base needs 4.8 seconds and reaches 230 km/h, while the Turbo takes 2.5 seconds and tops out at 260 km/h. The review notes that even the base version would be more than adequate for everyday driving.
Two reworked components
Although the Cayenne shares the PPE foundation with the Macan, Porsche redeveloped two central components for it: the battery is integrated more deeply into the vehicle structure, and the S uses 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 use permanently excited synchronous machines; the front motor is essentially derived from the Macan, but the rear unit is exclusive to the S and Turbo, while the base model uses a water-cooled drive. The Turbo's extra output comes not from a different motor but from a longer version of the same design.
An electrically non-conductive oil draws heat directly from the copper windings, whereas conventional water-jacket cooling requires heat to reach the outer jacket first. Porsche states the motor efficiency is 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 review found the S accelerated smoothly and forcefully without Launch Control, with consistent propulsion even under repeated full-throttle bursts.
Charging: datasheet versus reality
At an EnBW HyperCharger, the recording began at nine per cent state of charge (SoC), with 333 kW 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 datasheet's full 390 kW was not reached because of the charger, not the car: Porsche only provides 390 kW above 520 amps, and 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 Celsius and an SoC of 45 to 48 per cent.
The decisive figure for short breaks is the time to 80 per cent. After the first power drop, the Cayenne continued at around 290 kW; between roughly 60 and 71 per cent it held about 270 kW, and at 80 per cent it was still at 183 kW. From 10 to 80 per cent took about 16 minutes, matching the configuration; the review calls this a figure that stands out in the class.
Quiet Charging and its boundary
One drawback appeared during the first fast-charging session: the cooling fans were noticeably loud during charging and briefly afterwards. Porsche's Quiet Charging mode can only be activated manually via the display after charging has started. It reduces fan speed, which lowers cooling performance and lets the battery heat faster; only when the battery reaches its limit temperature does the vehicle have to adjust charging power. In the review's comparison, the same 10 to 80 per cent charge still took about 16 minutes, with a peak of 385 kW; in Quiet mode the high plateau ended earlier, at 42 per cent, so at 44 per cent the car drew 325 kW instead of 386 kW.
Porsche frames Quiet Charging primarily as a noise-reduction feature. Under moderate conditions, only the volume falls; a noticeable performance reduction occurs at high starting battery and ambient temperatures. The manufacturer gives an example of a 10 to 80 per cent session at a starting battery temperature of 35 degrees and an ambient temperature of 45 degrees, where charging time can be extended by around one minute. The review notes that a single run each cannot be generalised.
Chassis and driving behaviour
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, while the test vehicle added Porsche Active Ride at €8,324. Its active dampers connect to a motor-pump unit on each axle and generate targeted forces without mechanical stabilisers. In Comfort mode the system can overcompensate roll and pitch to reduce the forces on occupants; the review describes the car ironing out roughness and leaning slightly into curves rather than outward, while Sport and Sport Plus keep the body flat without harsh tuning. Rear-axle steering, at just under €1,700, cuts the turning circle from 12.7 to 11.6 metres and is strongly recommended. The weight cannot be fully masked: pushed hard, the S understeers out of a curve, and the 22-inch wheels pass short, sharp edges into the cabin. Regenerative braking is blended into the brake pedal almost imperceptibly, and the test car's optional ceramic brakes cost €10,100 but are not needed for everyday energy recovery.
Battery, efficiency and range
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 — a change of cell format 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 versus the previous NMC-811 chemistry, giving the pack eight kilowatt-hours more than the Taycan's while being around 103 litres more compact. Pre-conditioning is triggered automatically through the Charging Planner when a charging stop is set as a navigation destination, but Porsche offers no manual start, so a spontaneous fast-charging stop cannot pre-heat the battery.
The specific configuration is quoted at a combined WLTP range of 616 kilometres; the S Coupé line reaches up to 669 kilometres, the S SUV up to 653, the base Coupé up to 661 and the Turbo 637. On mixed routes, consumption varied between roughly 20 and 27 kWh/100 km depending on speed, settling around 24 kWh/100 km in everyday mixed driving.
Packaging, towing and cabin
The Coupé's flatter roofline slightly reduces practicality compared with the SUV. The luggage compartment holds 534 to 1,347 litres plus 90 litres in the front trunk, with only the Turbo offering less at 500 litres; rear headroom is slightly tighter but still sufficient. All three electric Cayenne variants can tow up to three tonnes when braked, and the optional Off-Road Package at €2,492 raises this to 3.5 tonnes. Infotainment runs through the curved Flow Display, and the test car added a passenger display and an augmented-reality head-up display. The review found some functions buried in submenus and the navigation map occasionally abrupt, but praised the optional surface heating at €934, which warms the armrests and door panels.
Price, options and positioning
The S Coupé starts at €130,300, but the tested configuration added €69,440 of options for a total of €199,740; Active Ride, the ceramic brake system and the lightweight sport package alone accounted for €34,589. The report argues that a relatively modest entry price paired with a long, high-priced options list is the norm at Porsche, and that expensive extras with low production costs are particularly profitable, whereas substantive features such as Active Ride are the exception. It cautions that the driving experience with active suspension and rear-axle steering cannot be transferred directly to a standard base S, even though 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 related Audi Q6 e-tron and Porsche's own Macan Electric ranked one class below.
