New Porsche 911 Carrera 4: Official

Porsche has revealed details of the new Porsche Carrera 4 ahead of its debut at the 2012 Paris Motor Show. After we published the first leaked photos of the 2013 Porsche Carrera 4 at the weekend it seemed likely that Porsche’s own reveal wouldn’t be far behind, and here it is. As expected, we get the reveal not just of the 911 Carrera 4 and Carrera 4S, but the cabriolet version as well as the coupe; a full set of new Porsche 911s.

Next-gen Passat to offer hybrid and twin-turbo power

VOLKSWAGEN is going even more upmarket with the all-new version of the Passat, which is due to hit showrooms later this year. Soon buyers will be able to include a plug-in hybrid and an all-new 2.0-litre twin-turbo diesel among their forecourt options, as VW goes chasing after its sister company Audi. Weight-saving measures have chopped up to 85kg from the new kid on a like-for-like basis, which helps achieve VW's stated efficiency boosts of 20% versus equivalent outgoing Passats.

Audi RS6 Avant is the Audi R18 e-tron quattro for the road (video)

In a new video to promote the RS6 Avant – perhaps the pick of the crop of current uber-estates – Audi has the e-tron quattro out on the road in a series of familiar everyday pursuits. So we get the e-tron quattro waiting patiently to collect hubby from the airport, as the c ar to drive to the hills to ride a mountain bike, outside a hotel with luggage on the pavement, collecting the kids from school, parked on the river bank for a fishing trip and as a dog transporter.
