Porsche Cayenne Coupe Electric: which version to buy (S AT, AT, or Turbo AT)

The Porsche Cayenne Coupe Electric is a one-generation SUV Coupe, on sale from April 2026 with no end date in the data. The catalogue lists three versions — AT, S AT, and Turbo AT — all Electro, all Automatic with 1 speed, all AWD. There is no second generation to compare, so the buying question is entirely between these three.

The Porsche Cayenne Coupe Electric is a one-generation SUV Coupe, on sale from April 2026 with no end date in the data. The catalogue lists three versionsAT, S AT, and Turbo AT — all Electro, all Automatic with 1 speed, all AWD. There is no second generation to compare, so the buying question is entirely between these three. AT and S AT share 442 hp, 835 Nm, 4.8 s to 100 km/h, and the same 2530 kg kerb weight; they split only on top speed (230 vs 250 km/h). Turbo AT is the outlier: 1156 hp, 1500 Nm, 2.5 s, 260 km/h, and 2650 kg. If you want the same powertrain for less top speed, that is AT. If you want 20 km/h more without extra horsepower, that is S AT. If you want more than double the power and a 2.3 s shorter 0–100, that is Turbo AT.

Cayenne Coupe Electric specs by version: what actually differs

One generation, key 8865, body SUV Coupe, production start 2026-04-01, stop not measured, 3 versions. No restyling is listed. Cylinder count, cylinder layout, boost, displacement, valves, engine position, and feed system are not measured on every version — these are electric drivetrains, not a petrol catalogue with a litre figure.

That means classic “power per litre” cannot be calculated for AT, S AT, or Turbo AT. What can be calculated is power per kilogram, payload, and how much extra speed and torque each step buys.

AT and S AT are identical in the engine table: 442 hp (325 kW) and 835 Nm, Electro, Automatic, 1 speed, AWD. Turbo AT adds 714 hp (1156 − 442) and 665 Nm (1500 − 835). In ratio terms, Turbo AT has 2.62 times the horsepower of AT / S AT (1156 ÷ 442) and 1.80 times the torque (1500 ÷ 835). Kilowatts follow the same split: 325 kW on AT and S AT, 850 kW on Turbo AT — a 525 kW gap.

There is no displacement, so do not treat Turbo AT as a “larger engine.” The data name is Turbo AT; the fuel label is still Electro. Boost is not measured on all three, including Turbo AT.

AT vs S AT (same 442 hp). Acceleration is the same: 4.8 s. The only performance number that moves is top speed: S AT is 20 km/h faster (250 − 230). That is the entire “S” premium in this dataset. If your use is 0–100 and everyday AWD, AT and S AT are the same car on paper except the limiter. If you care about the last 20 km/h, S AT is the one that records 250 km/h.

S AT vs Turbo AT. Turbo AT cuts 0–100 from 4.8 s to 2.5 s2.3 s quicker, or 1.92 times the average acceleration over that sprint (4.8 ÷ 2.5). Top speed rises from 250 to 260 km/h, only 10 km/h more than S AT and 30 km/h more than AT. Most of what Turbo AT buys is launch and torque, not a large extra slice of top speed versus S AT.

AT vs Turbo AT. Same 2.3 s 0–100 gap, plus 30 km/h on top speed (260 − 230). Torque jumps by 665 Nm. There is no middle electric version between 442 hp and 1156 hp in this generation.

Economy / mpg. City, highway, and combined consumption are not measured for AT, S AT, and Turbo AT. Tank volume is not measured. CO2 and eco class are not measured. You cannot rank versions on mpg, range, or charging from this catalogue. Any “which is cheaper to run” argument has to stop at kerb weight and power: Turbo AT is heavier and more than twice as powerful, but the data do not quantify energy use.

Dimensions and weight

Ground clearance is not measured on all three. Wheel options differ.

Turbo AT2650 kg3250 kg600 kgnot measurednot measured275/45 R21, 315/40 R21

AT and S AT share 2530 kg kerb and 3145 kg gross. Turbo AT is 120 kg heavier at the kerb (2650 − 2530) and 105 kg heavier gross (3250 − 3145). Payload is 15 kg lower on Turbo AT (600 vs 615). The extra mass does not buy extra rated load; it buys the 1156 hp pack.

Weight per horsepower (kerb ÷ hp):

Turbo AT carries 3.43 kg less per horsepower than AT / S AT (5.72 − 2.29). Even after the 120 kg penalty, specific mass is far lower. Per kW: AT / S AT are 2530 ÷ 325 ≈ 7.78 kg/kW; Turbo AT is 2650 ÷ 850 ≈ 3.12 kg/kW.

Wheels. AT and S AT list four sizes: 255/55 R20, 275/45 R21, 305/45 R20, 315/40 R21. Turbo AT lists only two: 275/45 R21 and 315/40 R21. The 20-inch options (255/55 R20 and 305/45 R20) are not in the Turbo AT row. If you want a 20-inch fitment from this list, the data only attach it to AT and S AT.

Chassis labels (same English tags on all three): front suspension Independent, pneumatic; rear Independent, spring; front brakes Ventilated disc; rear brakes Disc ventilated. Clearance is not measured, so ride height is not a buying differentiator here.

Which version to choose

Prices are not in the data, so “extra money” means extra hp, Nm, speed, and kilograms, not currency.

Choose AT if you want the 442 hp Cayenne Coupe Electric without the higher top speed

AT is 442 hp, 325 kW, 835 Nm, Electro, Automatic 1-speed, AWD, 4.8 s, 230 km/h, 2530 / 3145 kg. Against S AT it gives up 20 km/h and nothing else measured: same power, same torque, same 0–100, same weights, same four wheel sizes, same suspension and brake labels. Against Turbo AT it gives up 714 hp, 665 Nm, 2.3 s on 0–100, 30 km/h on top speed, and it is 120 kg lighter. If 230 km/h is enough and you do not need 1156 hp, AT is the lightest, lowest-power, four-wheel-option entry.

Choose S AT if the only gap you want to close versus AT is 20 km/h

S AT is not a more powerful motor in this table. It is the 442 hp car with 250 km/h instead of 230. That is a 8.7% top-speed step (20 ÷ 230). 0–100 stays 4.8 s. Kerb stays 2530 kg. Wheels stay the four-size set. Versus Turbo AT, S AT is still 714 hp down, 2.3 s slower to 100, 10 km/h slower at the top (260 − 250), and 120 kg lighter. Buy S AT when the catalogue’s AT row is the car you want except the 230 km/h cap.

Choose Turbo AT if the numbers you care about are 1156 hp, 1500 Nm, and 2.5 s

Turbo AT is the only version that is not a 442 hp twin. It is 1156 hp (850 kW), 1500 Nm, 2.5 s, 260 km/h, 2650 / 3250 kg, wheels 275/45 R21 and 315/40 R21 only. You pay 120 kg kerb and 15 kg of payload versus AT / S AT, and you drop the 20-inch tyre lines. What you get is 2.62× horsepower, 1.80× torque, 2.29 kg/hp instead of 5.72, and a 0–100 that is 52% shorter in time (2.3 ÷ 4.8). The top-speed gain versus S AT is only 10 km/h — small next to the power jump — so Turbo AT is the launch-and-torque choice, not a large extra motorway-speed step over S AT.

What this generation does not let you choose

There is only 1 generation (from April 2026, stop not measured). You cannot pick a later body or a restyle; there is no second generation in the file. You cannot pick a different gearbox type or drive: every version is Automatic, 1 speed, AWD. You cannot pick by mpg, tank, CO2, eco class, ground clearance, cylinders, layout, or boost — all not measured. You cannot split AT from S AT on weight or horsepower. The real fork is:

1. 442 hp / 4.8 s / 2530 kg → then AT (230 km/h) or S AT (250 km/h). 2. 1156 hp / 2.5 s / 2650 kgTurbo AT (260 km/h).
