2027 Porsche Cayenne Coupe Electric E4 Slate Grey
By Lorenzo Bianchi July 27, 2026
Porsche has revealed the Cayenne Electric family, including a Coupe body style, spanning three trims: Cayenne Electric, Cayenne S Electric, and Cayenne Turbo Electric, all with electric all-wheel drive.
The Cayenne Turbo Electric and Turbo Coupe Electric top the range with up to 850 kW (1,156 PS), 1,500 Nm of torque, and a 0-100 km/h time of 2.5 seconds.
An 800-volt architecture allows charging at up to 390 kW, taking the battery from 10-80% in under 16 minutes, with a WLTP range of up to 669 km on the Cayenne S Coupe Electric.
A New Era for the Nameplate
The target naming used for this piece — "2027 Porsche Cayenne Coupe Electric E4 Slate Grey" — does not match anything in the source material provided. The official press release, dated 24th July 2026, makes no mention of a 2027 model year, an "E4" designation, or a Slate Grey colourway; the only specific paint reference in the document is Mystic Green Metallic, tied to an optional interior package. What follows is built strictly from the verified press material, with the unmatched naming elements flagged rather than assumed.
Design Language and Proportions
Porsche describes the Cayenne Coupe Electric as sharing its 4,985 mm length with the standard SUV body, while matching its 1,980 mm width. Where it differs is height — the Coupe sits 24 mm lower, at 1,650 mm. Both versions ride on a wheelbase Porsche says is noticeably longer than the combustion-engined Cayenne, freeing up rear-seat space. Frameless doors, an elegant flyline, and an animated light signature carry the design language, while a drag coefficient of 0.23 for the Coupe — against 0.25 for the SUV — puts it among the more aerodynamically efficient shapes in its class.
Cabin Technology
Inside, the new Porsche Digital Interaction concept combines touch surfaces with physical controls and a curved centre display called the Flow Display. The system supports streaming, gaming, app integration, and voice control, alongside customisable Mood Modes that tie ambient lighting, seat settings, and climate together. Rear seating in the Coupe is offered as a two-seat or 2+1 layout with electric backrest adjustment.
Power and Performance
At the top sits the Cayenne Turbo Electric and Turbo Coupe Electric, producing up to 850 kW, or 1,156 PS, with 1,500 Nm of torque. Porsche quotes a 0-100 km/h sprint of 2.5 seconds and a top speed of 260 km/h, with a Push-to-Pass function adding a further 130 kW for short bursts. The rear-axle motor, developed in-house and derived from Formula E technology, uses direct oil cooling and silicon carbide inverters to sustain output under repeated hard use — a detail Porsche is keen to point out given how quickly heat can blunt EV performance on track.
Range, Charging and Chassis
A 113 kWh battery, built from six modules and 192 cells, underpins WLTP range figures of up to 669 km on the Cayenne S Coupe Electric. The 800-volt system allows charging at up to 390 kW, with a 10-80% top-up in under 16 minutes, and Porsche Wireless Charging offers inductive top-ups at up to 11 kW. Adaptive air suspension is standard across the range, with rear-axle steering, Torque Vectoring Plus, and Porsche Active Ride available depending on trim.
Practicality and Positioning
Luggage space runs to 1,347 litres in the Coupe, plus a 90-litre front storage area, with towing capacity up to 3.5 tonnes depending on market. [Unverified] The release does not name direct rivals, so how the Cayenne Coupe Electric is positioned against competing electric performance SUVs isn't addressed in the source material.
