Mercedes at 2013 Goodwood Festival of Speed – includes SLS AMG Black Series debut

The Mercedes SLS AMG Black Series (pictured) debuts at 2013 Goodwood FoS In case you hadn’t noticed, it’s the Goodwood Festival of Speed this weekend and car makers are out in force with their fastest supercars and classics. Mercedes always offer a decent show at Goodwood and this year is no different, with the UK dynamic debut for the Mercedes SLS AMG Black Series, which will be strutting its stuff all weekend up the hillclimb. At the other end of the performance range, the Mercedes A45 AMG is also in action showing the crowds just what 360bhp in a compact hatch can do with its runs up the hillclimb.

Algae-powered street lights eat CO2

Algae powered street lighting (great Photoshop) A French biochemist – Pierre Calleja – has developed a street lighting system using micro algae that absorbs CO2. The need to reduce CO2 in the atmosphere is contentious - to say the least – but as long as governments use CO2 as a stick to beat motorists and empty their bank accounts it’s sensible to look at ways of ‘balancing’ the CO2 emissions of cars. French biochemist Pierre Calleja thinks he’s come up with a solution that would neutralise CO2 emissions from cars by cancelling it out with his micro-algae lighting.

Renault Alpine A110-50

As we reported earlier this week, the Renault Alpine A110-50 prototype will be shown at the 2012 Monaco Grand Prix this weekend. Designed by Yann Jarsalle and Concept and Show Car Director Axel Breun the A110-50 effectively relaunches the historic Alpine brand despite being essentially a reworked version of the Renault-branded DeZir concept unveiled at the 2010 Paris Motor Show. As well as the addition of various Alpine design cues – the stylized yellow spot lamp pods, central hood flute and blue and orange colorway – the car is built on the platform of the RenaultSport Megane Trophy racecar and so therefore requires cooling provisions for its mid-mounted engine.
