London Congestion Charge: Buy 76-100g/km car NOW to get 3 years free of charge

Whether you think the London Congestion Charging Zone is a great way to clean up the air quality of the capital or just another way to tax motorists, you’re going to struggle even more to avoid it after the emission exemption levels are changed on 1st July so only cars emitting 75g/km CO2 or less will be exempt from the charge, Boris says the new lower level is necessary because car makers have worked their socks off to produce small diesel cars with the ability to hit the magic sub 100g/km emissions level in recent years, and that means London is suffering from air pollution as a result. The only answer, apparently, is to drop the limit to 75g/km or less to make those ‘dirty’ diesels pay their way. By reducing the limit to 75g/km you are effectively only allowing EVs and Plug-ins an exemption from congestion charging, thereby moving their emissions off to wherever the electricity they use is produced.

Maserati Quattroporte

Maserati has revealed the first pictures and details of the 2013 Quattroporte ahead of its official debut at the Detroit auto show in January. The sixth-generation Quattroporte, a high-performance sports luxury saloon, will be the first of three new models that Maserati hopes will begin to increase its annual sales. The car retains some of the design cues from the outgoing model, namely the front grille, three side vents and the triangular C-pillar, while it also features a sharp beltline that rises towards the car's rear and runs through the side of the car.

Audi R8 e-tron Nurburgring record run on video

Audi has revealed video of the complete Nurburgring lap by the Audi R8 e-tron in 8:09, a new lap record for an EV. The Nurburgring is not the first place you’d associate with an electric car. After all, it’s fuelled on adrenalin, testosterone and the sound of V8s, V10s and V12s – not batteries and whooshing noises.
