Boris planning war on diesel car drivers – London Mayor wants drivers of diesel cars to pay more

Boris wants to charge diesel cars an extra £10 to enter London We’ve long banged on about the nonsense of basing the cost of motoring on the Co2 emissions of cars, and it seems the London Mayor, Boris Johnson, also realises that Co2-based taxation has led to a real pollution problem. As we reported as far back as 2010, petrol cars – certainly before the introduction of Euro 6 emissions recently – are far cleaner than diesel cars when it comes to the sort of stuff that really matters – NoX and particulates. And the problem has been exacerbated by basing car taxation on Co2 emissions as lower Co2 levels have been much easier for car makers to achieve on diesel engines, which is why diesel-engined cars now account for around 50 per cent of all cars sold in the UK.

Mercedes Biome (2010) first official pictures

Now, what on earth, or for that matter not from earth have we got here? It's the Mercedes Biome concept supercar. It's a product of Merc's Los Angeles design studio, and they prefer to describe it as an 'Ultralight vehicle at one with nature.' The Biome was produced as part of the Los Angeles Design Challenge, taking part alongside the 2010 LA auto show.

Ssangyong getting bullish with the Korando SX

The new Ssangyong Korando SX is to feature in a £1 million TV advertising campaign comparing price and spec with its rivals. It’s almost exactly a year since we reported Ssangyong’s return to the UK market with the Ssangyong Korando, a competitive budget compact SUV they hoped would set them on a path to sales success in the UK. Ssangyong ramped up their Korando offering in June by launching the Korando SX 4×4 at a very reasonable £18,795, although you did have to sacrifice kit – and a lump of power – to achieve the new 4×4 entry price.
