New Porsche Cayenne Turbo E-Hybrid: 729bhp super-SUV unveiled

There was a time when power figures beyond 700bhp were reserved for the most exclusive, technologically advanced supercars, but now such colossal outputs are within reach for high-performance SUVs. The new Porsche Cayenne Turbo E-Hybrid is the latest to join the 700bhp+ club and arrives as something of a consolation gesture in the UK, given that the ultra-focused Cayenne Turbo GT is no longer sold on our shores. 

With a 4-litre V8 plug-in hybrid powertrain rated at 729bhp and 701lb ft of torque, the Turbo E-Hybrid is the most powerful Cayenne to date. The petrol engine contributes 591bhp to the total output, with a single supplementary electric motor generating 174bhp. Completing the 0-62mph sprint in 3.7sec, the Turbo E-Hybrid sits in a similar ballpark to the BMW XM Label Red (3.8sec) and the Lamborghini Urus S (3.5sec) in terms of acceleration. With a larger 25.9kWh battery than its predecessor, the Turbo E-Hybrid can drive up to 51 miles on electric power alone, and features an 11kW on-board charger for quicker top-ups than before. 

This new model effectively serves two roles: on one hand, it’s a successor to the previous Turbo S E-Hybrid model, but on the other, it aims to provide some of the extra bite and ability of the Turbo GT by offering an optional GT Package for the model in its Coupé form. All Turbo E-Hybrids come equipped with two-chamber air suspension with adaptive dampers and torque vectoring, but the GT Package takes things further with bespoke suspension tuning and software calibration. The GT Package also drops the ride height by 10mm and applies new geometry and bespoke front suspension pivot bearings to increase camber.

Porsche’s carbon-ceramic braking system is also included, along with higher-specification tyres, Porsche Dynamic Chassis Control and rear-wheel steering. With a carbonfibre roof and diffuser, plus a twin-exit titanium exhaust system, the GT Package brings a similar visual flavour to the standalone Turbo GT. 

Inside, the new tech that debuted with the facelifted Cayenne is present and correct, centring around a 12.3-inch touchscreen mounted above a redesigned centre console. A curved digital instrument panel and an optional passenger display take heavy inspiration from the Taycan, while Porsche’s HD Matrix LED headlight technology comes as standard. Prices start at £130,200, with the Turbo E-Hybrid Coupé costing £132,600. The GT Package commands a hefty £21,400 premium on top of this.
