Ultra-rare Steyr Puch 500 goes to auction

£18,000 might seem like a lot of money for a car based on the original Fiat 500, but this particular Steyr Puch example is one of just 33 ever built. Austrian firm Steyr Puch entered into an agreement with Fiat in 1954 after production was halted during World War II, and began production of the 500 under licence. Only 33 right-hand drive examples were ever produced, and of those only two survive; this example and one in the Steyr Puch museum in Austria.

Better Place Electric Car visitor centre opens

Better Place have opened a visitor centre in Israel to demonstrate their battery swap technology for electric cars Last October we wrote about a start-up company in Israel – Better Place – that had a new way forward for electric cars by taking the purchase of battery packs out of the equation, and was developing a system for ‘Battery Swap’ stations where electric car owners could drive in and swap their battery pack for a fully-charged one in a few minutes. That story first brought to our attention our favourite quote of last year – by Nissan boss Carlos Ghosn – who said “A hybrid is like a mermaid: if you want a fish, you get a woman; if you want a woman, you get a fish.” Which probably explained why Nissan – and its partner Renault – got involved with Better Place. Better Place aims to address the main concerns of electric car drivers by making the battery packs in electric cars ‘swappable’.
