What do you look for in an SUV? High driving position? Big boot? Pavement-scaling ground clearance?

How about 700 horsepower? Porsche tuning specialist Techart has announced a new ‘powerkit’ for the Cayenne Turbo, taking its power output to a laughably inappropriate 690bhp and torque to 679lb ft. Autobahns beware.

How much faster is the Techart-tuned Cayenne Turbo compared with a regular model?

The regular Cayenne Turbo musters 513bhp and 552lb ft from its 4.8-litre V8. Equipped with the new Techart TA058/T2 powerkit (catchy name, eh?) the 177bhp and 127lb ft boost allows a supercar worthy 0-62mph time of 3.9sec and a top speed as high as 191mph, depending on the wheels and tyres fitted. Perhaps more impressive still, the 2.1-tonne Techart Cayenne can get from 0-124mph in 13.8sec.  

The full 690bhp is accessed by a sport mode button; otherwise you just get a casual 631bhp under full load. Techart says that despite the massive power increase, fuel consumption only rises by 1% and emissions by an even smaller amount, remaining well within officially rated Euro6 limits. And who wouldn’t believe official emissions figures, eh?

What does the powerkit involve?

Designed to work with the standard Cayenne ECU, the kit includes an altered exhaust manifold design and new turbochargers manufactured by Techart, promising rapid boost pressure build-up for speedy throttle response. Beefed-up oil and water pipes, freer-breathing air filters and a new wiring harness also make an appearance.

Techart Magnum range

The new engine kit will be available as part of Techart’s ‘Magnum’ Porsche Cayenne range, the latest generation of which arrives before the end of 2015. The car pictured wears the latest Techart bodykit, described by the Leonberg firm as an ‘exterior refinement’ package. Refinement is in the eye of the beholder, after all.

This isn’t the first time Techart has wielded spanners in a Cayenne’s engine bay. The company’s other, slightly less power-crazed engine kits for petrol and diesel Cayennes continue unchanged. Click here to read Ben Barry’s review of the 2009 Techart Porsche Cayenne D Tech9.
