Since its introduction in 2002, the Porsche Cayenne has sold over 500,000 units, boosting the company’s profitability and helping to fund the development of the rest of the Porsche range.

The new third-generation Cayenne launched today, with a focus on economy and efficiency, spearheaded by the Cayenne S E-Hybrid.

It’s powered by a 3.0-litre supercharged V6 engine that develops 333hp coupled with a 95hp electric motor to produce a total of 416hp at 5,500rpm and 590Nm of torque from 1,250-4,000rpm.  The 0-62mph sprint is taken care of in 5.9 seconds, with a top speed of 151mph.

In the electric-only mode, a 10.9kWh lithium-ion battery provides power enough for 18 to 36km of driving, with a top speed of 77mph.

The Cayenne S features a new 3.6-litre biturbo V6 that Porsche says was developed entirely in-house, and it produces 420hp at 6,000rpm (up by 20hp over the out-going model) and 550Nm of torque (up 50Nm).  As a result, the 0-62mph sprint is 0.4 seconds faster at 5.5 seconds (5.4 with the Sport Chrono package) while the top speed is 161mph.  Despite this level of performance, fuel consumption is expected between 28.8 and 29.7mpg, with CO2 emissions in the 223-229 g/km range.

Two diesel engines are available, starting with the 3.0-litre V6 with 262hp and 580Nm.  It can accelerate from 0-62mph in 7.3 seconds (7.2 with Sport Chrono) and is expected to achieve 41.5-42.8mpg with CO2 emissions of 173-179 g/km.

The more powerful 4.2-litre V8 diesel churns out an impressive 385hp and 850Nm of torque, enough to propel it to 62mph in just 5.4 seconds (5.3 with Sport Chrono) and keep going until 156mph.  Economy is expected to be 35.3mpg with CO2 emissions of 209 g/km.

Top of the range, though, is the Cayenne Turbo.  A twin-turbo 4.8-litre V8 kicks out a compelling 520hp and 750Nm of torque, enough to get to 62mph in just 4.5 seconds (4.4 with Sport Chrono) before topping out at 173mph.  Economy isn’t likely to be too much of a concern, but is expected in the 24.5-25.2mpg range, with CO2 emissions of 261-267 g/km.

Porsche says it has tuned the chassis of the Cayenne to offer greater comfort and dynamic ability, while some of the improvements to the range’s efficiency come as a result of a new start/top system with coasting function plus new active air intakes that close at speed.

Styling-wise, the changes include sharper lines at the front, with entirely new front wings and bonnet.  New air blades direct air into the intercoolers, while the headlights incorporate bi-xenon lighting and LED running lights as standard.  The Turbo model features full LED headlights and Porsche Dynamic Light System (PDLS).

At the rear, the lights feature a new 3D effect, while the brake lights use four distinct elements.  The recess for the number plate and boot handle are now more cleanly integrated into the tailgate, which now includes electric operation as standard.

Inside, there’s a new multi-function sports steering wheel with gear-shift paddles as standard, the rear seating has been made more comfortable, and seat ventilation can now be added as an option.

All models feature bi-xenon headlights, front and rear parking sensors, cruise control, climate control and powered tailgate as standard, while the Turbo model adds LED headlights, 19-inch alloy wheels, PASM with air suspension, PCM satellite navigation and Bose surround sound audio system.

Prices start at £49,902 for the Cayenne Diesel, rising to £93,763 for the Cayenne Turbo.
