On the official combined fuel cycle it manages 159g/km and 41.5mpg, a big improvement on the Porsche Cayenne S Hybrid’s 34.3mpg and 193g/km, and comfortably ahead of the best non-hybrid Porsche, the PDK-equipped Cayman (31mpg and 214g/km CO2). The new Porsche Panamera S Hybrid will be unveiled at the 2011 Geneva motor show in March.

New 2015 Volvo XC90 – first exterior photo

The new Volvo XC90 (pictured) arrives in 2 weeks The reveal of the new 2015 Volvo XC90 is only two weeks away – although probably overdue by many years – and Volvo continue to pique our interest with more information on the new XC90. Top of Volvo’s information list this time is their new Scalable Product Architecture (SPA) which underpins the new mXC90, but in the process they have revealed the first exterior photo of the new XC90 (although the exterior has already been revealed), although it is only a front-end detail photo. What it does show is the XC90′s new headlights – complete with running lights Volvo has dubbed ‘Thor’s Hammer – which look similar to those found on a number of Volvo’s recent concepts, a much bigger grill than we’re used to seeing on a Volvo and a sculptured bonnet.
