Say whats up to essentially the most highly effective SUV to ever put on the Porsche badge: the 671bhp, 900Nm, two and a half tonne Cayenne Turbo S E-Hybrid. It pushes Porsche’s second greatest vendor into a completely new efficiency envelope, giving it the punch to compete straight with the Lamborghini Urus.
Key to offering that Lamborghini taming energy is the very same engine as you’ll discover within the Italian model’s super-SUV. On the coronary heart of this new Porsche is a turbocharged four.Zero-litre V8 engine producing 542bhp, but it surely receives the identical electrified help and extra grunt because the Panamera Turbo S E-Hybrid. Meaning an electrical motor growing 134bhp joins up with the petrol motor, and whereas they don’t develop peak energy fairly concurrently one another, the ensuing 671bhp may be very shut certainly.
The electrical motor resides between the engine and gearbox and is fed by a 14.1kWh battery. Porsche claims that in the event you preserve the cell topped up (a full recharge takes 2.four hours by way of the on-board 7.2kW charger), the automotive is sweet for nearly 25 miles on electrical energy solely. High velocity within the E-Energy electrical mode, which is the default drive mode chosen on begin up, is 84mph. It implies that the Cayenne Turbo S E-Hybrid can cruise emissions free on the motorway, however that is removed from the quietest automotive able to all-electric operating attributable to wind and highway noise, and that 25 mile claimed vary will disappear far quicker than that.[gallery:1]
That mentioned, the check route offered for our style of a pre-production Cayenne Turbo S E-Hybrid mentioned loads about the place Porsche believes this astonishingly highly effective folks mover will carry out to its full potential. Germany’s autobahns, and particularly the derestricted sections, are the place this Stuttgart-born leviathan actually makes essentially the most sense.
Round city the powertrain’s electrical factor is an excellent fall-back and can imply congestion cost exemption within the Capital when it arrives in Britain in October. However this large, heavy automotive, straining on the leash to profit from its huge energy reserves.
Few drivers can have the boldness to throw this large automotive exhausting into corners on twisty roads. Though it wears a Porsche badge, nothing might be executed to cover the sheer mass. The Cayenne Turbo S E-Hybrid ideas the scales at 2,490kg unladen of any passengers, with the Coupe heavier nonetheless at 2,535kg. Neglect any notions of poise, it’s a blunt instrument and unapologetically so.
This hybrid Cayenne is meant for tallying up mile after mile, in straight traces and at some velocity. Change into Sport Plus, flooring the accelerator, and the tempo builds on the identical monumental stage no matter gear or revs, and barely starting to lose its battle with physics as soon as above 150mph – you may thank the engine for that, as the electrical help shortly turns into out of date. The gearbox is an eight-speed torque converter, largely missing the crispness or immediacy of Porsche’s PDK transmission, however precision actually isn’t the Cayenne Turbo S E-Hybrid’s temporary.
It builds velocity with startling consistency and swagger – and a pleasant exhaust be aware – however not with out fuss. Highway and wind noise are fairly intrusive, and although three-chamber air suspension is normal – as is Porsche Lively Suspension Administration with adaptive dampers and the 48-volt assisted anti-roll system used on the Bentley Bentayga – the physics at play are unimaginable to beat.
With a lot tempo assembly a lot energy, the Cayenne Turbo S E-Hybrid is way from a advantageous using SUV. The Cayenne has by no means been a automotive to sacrifice its real skills for consolation, however whereas lesser, lighter members of the line-up exhibit way more in the way in which of dynamic involvement and pliancy, maybe this 671bhp hybrid is a lesson in overkill. Each of these key parts take a extreme hit, the trade-offs and primary promoting factors being two curious opposites: the power to run the automotive on electrical energy solely, and raucous straight line, V8 soundtracked efficiency in the event you so want.
Like almost all plug-in hybrid machines the combination of the battery takes its toll on practicality. The 14.1kWh battery is built-in underneath the rear bench, lowering the boot measurement from 745 litres to 645 within the case of the extra conventionally formed automotive, and right down to 500 litres within the newer Coupe, which instructions a £2,500 premium.
The cabin itself remains to be an immense setting, and high quality is each bit the Cayenne Turbo S E-Hybrid’s £120,000 plus price ticket ought to command. The driving place is as implausible as you’d count on too, however whereas the touchscreen infotainment is a slick setup, the centre console stays awash with considerably person unfriendly contact delicate switchgear. It’s good to have a look at, however a ache to make use of on the transfer.
