Following its debut at the Geneva Salon earlier this year, Porsche tuning specialist Techart has released new details on its souped-up Cayenne V6 Diesel. The German company's comprehensive tuning program for Stuttgart's first-ever production diesel model covers everything from engine and chassis conversions to interior and aerodynamic styling upgrades with buyers being able to buy Techart's Cayenne as new or add the kit to existing vehicles.

Beginning with the engine, Techart's power kit boosts the output of the Cayenne's 3.0-litre diesel from 240HP to 290HP while peak torque rises from 550Nm to 630Nm (465 lb-ft) at 2,200 rpm, with more than 500Nm being available from around 1,100 rpm to beyond 4,000 rpm.

The tuner claims that while 0 to 60mph sprint time drops from 8.3 seconds to 7.7 seconds, CO2 emissions and fuel consumption on the combined cycle remain unchanged at 244g/km and 30.4mpg UK (9.3lt/100 km or 25.3mpg US) respectively.

For cars fitted with air suspension, Techart offers a new suspension control module that lowers the vehicle, reducing roll and further improving aerodynamics. The Cayenne Diesel rides on new 21-inch alloy wheels fitted with Michelin Diamaris 4X4 XL 295/35 R21 tires.

Complementing the chassis and engine upgrades, is a full aero kit with a front panel with a deeper front spoiler, side skirts and a new rear apron with an integrated diffuser.

The package also comprises of headlight and tail lamp trims, twin double oval exhaust pipes, a three-spoke TECHART sports steering wheel with a Porsche airbag, and interior trim upgrades that include light-weight aluminum pedals and footrest and leather edged luxury logo floor mats.

Buyers can also opt for 22-inch body color wheels shod in 295/30 R22 Continental tyres, an Aero or Turbo-look bonnet, plus numerous interior options ranging from individual trim components to customized leather upholstery.

In the UK, the Cayenne Diesel with Techart's Aerokit 1 package that includes the exterior and interior upgrades is priced as new from £53,000 ($85,500 or €61,500) while adding the engine updates rises the price to £55,500 ($88,700 or €63,900.

For customers that already own a Cayenne Diesel, the Aerokit 1 can be fitted from £15,000 ($24,200 or €17,500) and the 290HP engine kit from £2,500 ($4,000 €2,900).
