Preview: All-new Porsche Cayenne Electric driven in Sepang - Still mind blowing

What happens when you unleash a 2.6-tonne electric SUV with supercar-rivalling power onto a Formula One circuit, though it has been a while since one, then throw it straight into mud, rocks, water crossings and rally-style dirt stages?

On paper, it sounds like a recipe of absolute contradiction. SUVs aren’t supposed to behave like sports cars. Electric vehicles aren’t supposed to feel exciting. And a luxury family hauler certainly shouldn’t be capable of embarrassing dedicated performance machines on a racetrack. Yet that’s precisely the point of the all-new Porsche Cayenne Electric, and what makes it such a weapon’s grade Swiss Army knife on four wheels.

During Porsche’s Asia Pacific’s regional preview event, the fourth-generation (E4) Cayenne made its first appearance in Southeast Asia, showcasing a model that could fundamentally redefine expectations of both electric vehicles and high-performance SUVs. More importantly, Porsche didn’t simply place the car on a display stand and talk about specifications. Instead, the company invited participants to experience its newest flagship in the harshest and most demanding environments possible, back to back

From our beloved Sepang International Circuit to challenging off-road trails softened by tropical rain, the Cayenne Electric was given every opportunity to prove that its extraordinary numbers translate into genuine real-world capability.

A New Chapter for Porsche’s Best-Selling SUV

The arrival of the E4 Cayenne marks a significant milestone for Porsche. More than two decades after the original Cayenne helped transform the company into a global success story, the SUV now enters its fourth generation as a fully electric model.

Importantly, Porsche is not abandoning internal combustion power altogether. The current third-generation Cayenne, available with petrol and hybrid powertrains with a couple of variants even proudly assembled out of Kulim, will continue to be sold alongside the new EV. This dual-strategy approach may not have been part of the original plan, but gives customers the freedom to choose between traditional combustion engines, hybrid technology, or a chance to see how far Porsche can warp expectations of something fully electric vehicle (again).

Built upon an evolved version of Porsche’s Premium Platform Electric (PPE) architecture, co-developed with Audi and already underpinning the latest Macan Electric, the Cayenne Electric benefits from an 800-volt electrical system and a noticeably larger footprint compared to its combustion-powered sibling.

To accommodate the massive battery pack, wheelbase has grown by 128 mm to slightly over 3 metres (3,023 mm, specifically). Overall length increases to 4,985 mm, while subtle dimensional adjustments make the SUV slightly lower and more streamlined than before.

Buyers can choose between the conventional SUV body style and the shockingly sleek Cayenne Coupé, which adopts a roofline heavily inspired by Porsche’s iconic 911 silhouette. The Coupé’s more aerodynamic shape not only enhances visual appeal but also contributes to greater efficiency and driving range. 

Active grille shutters, adaptive rear spoilers, aero-optimised wheels, front air curtains, a flat underbody, and a large rear diffuser help achieve drag coefficients as low as 0.25 for the standard body and 0.23 for the Coupé.

Three Variants, One Capable Of Bending Physics

Let’s talk specs, briefly. At launch, Porsche offers the Cayenne Electric in three distinct variants. The entry-level Cayenne Electric delivers 408 PS and 835 Nm of torque under normal operation, with launch control temporarily increasing output to 442 PS. Even this “base” model reaches 100 km/h in just 4.8 seconds before continuing to a top speed of 230 km/h.

Stepping up to the Cayenne S Electric brings considerably more firepower. Output rises to 544 PS and 1,080 Nm, while launch control boosts performance to an impressive 666 PS. The century sprint falls to just 3.8 seconds, accompanied by a 250 km/h top speed.

Then there is the flagship, at least for now. The Cayenne Turbo Electric exists in a completely different universe. Standard operation already provides a staggering 857 PS and 1,500 Nm of torque. Activate launch control, though, and power surges to an almost unbelievable 1,156 PS.

The result is 0-100 km/h dispatched in a mere 2.5 seconds. Zero to 200 km/h arrives in a scarcely believable 7.4 seconds. Top speed is electronically limited to 260 km/h, but as the Taycan Turbo S can touch 300km/h on a slight downhill incline, we suspect there’s little to mechanically limit the E4 from similar speeds.

Those figures place the Cayenne Turbo Electric firmly in supercar territory despite weighing approximately 2.6 tonnes.

The Drive: Sepang Reveals the Truth

Specifications are one thing, and it’s easy to handwave them with EVs. However, experiencing them firsthand, and in a Porsche, is something else entirely. One of the highlights of the launch programme involved acceleration runs and circuit driving at Sepang International Circuit. Been there? Done that? 

But it was here that the Cayenne Turbo Electric delivered its most shocking revelation. The acceleration is not merely fast, but physically overwhelming.

With launch control engaged, the SUV generates up to 1.13 G of acceleration force. The sensation is so intense that it compresses your chest into the seat, narrows your focus, and leaves little doubt about the immense performance available beneath your right foot. It might literally take your breath away if you’re not deliberately bracing yourself for the 1,500 Nm that arrives instantaneously.

No delay, no waiting for revs to build, and (ironically) no turbochargers to spool, nor much drama in putting all that power down. It feels raw with an oddly futuristic twist, perhaps aided by the ‘performance sounds’ piped across the cabin and emanating from the exterior. Repeated launches quickly become addictive, although they may also leave occupants feeling slightly disoriented after several consecutive runs, but also slightly euphoric. 

Yet perhaps the greatest surprise wasn’t the straight-line speed. It was the way the Cayenne carried itself through corners. And here’s where we get to the real magic. 

Porsche Active Ride Changes Everything

Physics suggests that a heavy SUV should lean, pitch, and struggle when subjected to aggressive direction changes. Porsche clearly disagrees.

One of the Cayenne Electric’s standout technologies is the newest iteration of Porsche Active Ride, making its SUV debut after first appearing on the latest Panamera, and most recently in the Taycan Turbo GT prior to this. The system replaces traditional anti-roll solutions with sophisticated hydraulically controlled dampers capable of actively, even predictively, managing body movements.

The effect is truly remarkable. Rather than allowing the vehicle to lean away from a corner, the suspension actively tilts the body toward the apex. Similar to a motorcycle leaning into a turn, the system reduces lateral forces acting on occupants while maintaining greater tyre contact with the road surface.

Body roll is virtually eliminated and the effect is a vehicle that feels dramatically lighter and orders of magnitude more agile than its actual mass would suggest. Cornering speeds increase, grip improves, and driver confidence, not to mention enjoyment, skyrockets. 

The sensations of taking it through the bends at Sepang can be described as surreal, struggling to process how something with these physical attributes can bully the asphalt so decisively into submission while remaining fully engaging through the pedals, the steering wheel, and the chassis responses. 

Combined with Porsche Active Suspension Management (PASM), the Cayenne still remains composed over imperfections while simultaneously delivering hypercar-car-like responses when pushed harder. All this was especially evident once we stepped out of the Cayenne Turbo and its laundry list of driver-focused innovation. 

Rear-Wheel Steering Works Its Magic

Helping disguise the Cayenne’s substantial dimensions is an advanced rear-wheel steering system. At lower speeds, the rear wheels can turn up to five degrees opposite the front wheels, effectively shortening the wheelbase and dramatically improving manoeuvrability. At higher speeds, the rear wheels steer in the same direction as the fronts by up to three degrees, enhancing stability during fast directional changes.

Despite measuring nearly five metres long, the Cayenne Electric boasts an impressively tight turning circle of just 11.1 metres. Navigating confined spaces feels far easier than expected, while high-speed transitions on track inspire confidence. 

More Than Just a Track Star

While circuit performance grabs headlines, Porsche was equally eager to demonstrate the Cayenne Electric’s substantial, but scarcely believable, off-road credentials. A dedicated course featured mud, loose surfaces, water crossings, steep inclines, rocky obstacles, and deeply rutted sections designed to challenge traction and suspension articulation.

Conditions became even more demanding after rainfall transformed hard-packed surfaces into slippery mud baths. The Cayenne simply shrugged it off, and once the course opened up, the Cayenne took that to mean transforming into a rally car, rocketing across the unpaved rough terrain with simultaneous grace and aggression. 

Porsche’s Active Traction Management and adaptive air suspension, the SUV maintained remarkable composure despite being bombarded with obstacles. The latter feature also means ground clearance can be increased from a low-slung 162 mm to a substantial 245 mm when Off-Road II mode is selected.

Maximum water-wading depth stands at 550 mm, while an optional off-road package improves approach angles through revised bumper design. Although few owners are likely to subject their luxury electric SUV to extreme trail adventures, it is reassuring to know the capability exists. More importantly, the engineering demonstrates Porsche’s commitment to preserving the Cayenne’s versatility despite its transition to electric propulsion.

Impressive Range and Ultra-Fast Charging

Touching back on spec sheet, power comes from a substantial 113 kWh battery pack. Despite the performance on offer, range figures remain highly competitive. Depending on variant and body style, WLTP-rated driving range extends from 624 km to as much as 669 km.

Charging performance is equally impressive. The 800-volt architecture supports DC charging rates of up to 390 kW, with peak capability reaching 400 kW under ideal conditions. This allows the battery to recharge from 10 to 80 percent in less than 16 minutes.

The Cayenne also supports 11 kW AC charging as standard, with an optional 22 kW upgrade available. Remarkably, Porsche is even offering factory-installed wireless charging capability at up to 11 kW—an industry first for a production EV.

A Luxury Lounge, Digital With Analogue Flair

Inside, the Cayenne Electric embraces a thoroughly modern digital environment. A 14.25-inch curved OLED instrument display sits ahead of the driver, complemented by Porsche’s new Flow Display taking centre stage, measuring an approximate 12.6-inches. There’s also an optional 14.9-inch passenger, if you’re interested. 

Wireless Apple CarPlay and Android Auto come standard, supported by AI-enhanced voice controls and an extensive suite of advanced driver assistance systems that, to be honest, we never got a chance to test out given how much actual driving we were doing. Still, it’s good to have we suppose. 

Rear passengers benefit from increased legroom thanks to the stretched wheelbase, while cargo capacity reaches 781 litres in the standard SUV. An additional 90-litre front trunk provides even more storage.

Porsche claims buyers can configure up to 110,000 different combinations of colours, materials, trims and seating options, ensuring no shortage of personalization opportunities.

Resetting Expectations

For decades, Porsche enthusiasts have joked that the company has always done things differently. The engine sits at the rear. The ignition traditionally sits on the left side of the steering wheel. Conventional wisdom rarely dictates Porsche’s engineering decisions.

The Cayenne Electric continues that tradition. By every traditional measure, a 2.6-tonne luxury SUV should not accelerate like a hypercar, attack corners like a sports sedan, and confidently tackle off-road terrain—all while offering over 600 kilometres of driving range.

Yet somehow, Porsche has achieved exactly that.

Just as the original Cayenne helped establish the benchmark for a truly engaging driver-focused SUV, its electric successor aims to demonstrate that cutting-edge technology and emotional appeal can coexist seamlessly.

Despite being the second go-around of sampling the E4 Cayenne’s arsenal of capabilities, and the first time we did so behind the wheel, what we've experienced so far is only a glimpse of the Cayenne E4's full potential. If the Taycan was the spearhead that showcased Porsche’s electric ambitions, the Cayenne E4 feels like an even more formidable statement of intent; combining precision, performance and presence in a package of remarkable capability.

As the automotive industry continues its transition towards an increasingly electrified future, Porsche’s philosophy remains unchanged. Regardless of what powers the wheels, the driving experience must continue to stir emotions. The Cayenne E4 appears determined to prove that excitement, character and driver engagement can thrive even in near silence.
