A range of tuning and styling options for the Porsche Cayenne Diesel has been introduced by Techart, the German tuning company.
Upgrades include sportier engine, chassis, bodywork and interior enhancements.
The power kit boosts output from the Cayenne's 3.0-litre diesel engine from 240bhp to 290bhp and more importantly raises torque significantly at just 2,200 rpm.
The CO2 emissions are unchanged at 244g/km and economy is 30.4 mpg.
Techart spokesman Phil Hindley, says: ``The 0-60 time drops from 8.3 seconds to 7.7 seconds, which is an impressive improvement but the real benefit is that the huge torque and very flat delivery provides impressive acceleration from any speed.
"It feels more like a big V8 than a highly efficient diesel V6."
In addition to the power hike option there is also an Aerokit Pack that includes a revised front panel with a deeper spoiler and integrated driving and fog lamps plus additional cooling vents.
At the rear there is a low-drag roof spoiler.
For vehicles with air suspension there is a control module that lowers the ride height in order to improve aerodynamics and reduce body.
The Techart Diesel Cayenne costs from £53,000 - some £13,000 more than the standard Cayenne diesel - and with the Powerkit prices are from £55,500.
