No hybrid convertibles are currently for sale in the United States. However, PGO has just announced a clean natural gas version of it’s speedster, the PGO Cevennes Turbo which can also run on biogas. Modeled after the 1950s Porsches, it looks fantastic. Six gear manual transmission and a turbo-charger – to compensate for the four cylinders. Top speed of 130 mph and 0-60 in just over six seconds. Unfortunately, it’s sold in Euros – and with the dollar where it is: €48,000 is…brace yourself, $75,000.
