Mitsubishi Concept G4 to debut in Bangkok

Mitsubishi will unveil its Concept G4 at the upcoming Bangkok motor show. The Concept G4 compact sedan is shown in only one sketch, meaning we have few details, but we can see it features Mitsubishi's latest design language first seen on the CA-MiEV in Geneva, for example the headlamps, rear lamps, vertical fog lamp bezels and grille. Mitsubishi claims that the concept's short nose will help with visibility and maneuverability, while the interior will allegedly be among the roomiest in its class.

Porsche Cayenne S Diesel: The V8 diesel Cayenne arrives

Porsche has revealed the 2013 Cayenne S Diesel with a 4.2 litre V8 diesel offering 378bhp, 626lb/ft of torque and 0-62mph in 5.7 seconds. Back in April we reported that the Porsche Cayenne S Diesel was on its way with a V8 diesel engine to take on the BMW M50d and the upcoming offerings from Land Rover with a 2014 4.4 litre Range Rover Sport seeming a likely possibility. Now Porsche has caught up and revealed the Cayenne S diesel, which gets the 4.2 litre diesel V8 with a healthy 378bhp and a very useful 626lb/ft of torque, enough to scoot the Cayenne S Diesel to 62mph in 5.7 seconds – a bit slower than the M50d, but all that torque should make it feel at least as lively.
