Koenigsegg Agera & Agera R 2012 updates

The Agera & Agera R get a raft of tweaks for 2012 Koenigsegg has revealed improvements to the Agera and Agera R for 2012, which will debut at Geneva next week. We’re not sure just how many Koenigsegg Agera R models have actually been built and delivered (or the standard Agera R, for that matter), but however many it is it’s not more than a handful. Still, standing still means going backwards – whether you’ve built a single car or a million – so Christian von Koenigsegg and his men in the snow in a shed in Sweden have been busy putting the Agera and Agera R at the cutting edge for 2012 models.

Ferrari 458 Speciale to debut at Frankfurt motor show

Update: Preview video added below, and yes, you can hear the car's engine -- barely -- through the thumping movie trailer-like music. A new Prancing Horse is set to go public at the 2013 Frankfurt motor show: Ferrari will use the event to introduce the 458 Speciale, which will join the 458 Italia and 458 Spider at the lower end of Ferrari's range. Visually, the 2,844 lb., mid-engined 458 Speciale doesn't depart too much from the 458 Italia, though the new model gets a more aggressive fascia and a massive hood duct that -- when coupled with an apparently F1-inspired interior -- hints at the no-nonsense sporting purpose of the car.

Alfa Romeo 4C

The production version of the Alfa Romeo 4C will make its debut at next month's Geneva motor show, two years after the concept appeared. Largely unchanged from the prototype, the 4C retains its mid-engined layout, short and wide proportions (less than 4,000mm long, 2,000mm wide, 1,180mm high and a 2,400mm wheelbase) and broadly similar surfacing. The changes appear to be more focused around productionized details.
