It is no secret that I get excited about auto racing. One of my favorite racing series is the American Le Mans (ALMS), which pits many factory-based cars against each other on some of the best tracks in the country. This weekend the race is coming to my home state of Connecticut (yes, I will be there), and it gets double points for being a race series with some exceptional green credibility. From using synthetic oil made from animal fat to encouraging racers to explore and use alternative fuels, the ALMS is influencing the way a lot of other race series look at alternatives to petrol power.

Porsche, who earlier this year unveiled a flywheel-hybrid 911 GT3 R, announced today that that car will run in the last race of the ALMS series. Are they planning on tackling the whole series next season?
