# 5: Cash for Clunkers: The Data On Why It's Working. Controversial when we wrote it, the content of this article got swamped in the partisan debate over whether Cash for Clunkers was a good thing or an abomination. Bottom Line: Older, lower-mileage vehicles got traded in for new, higher-mileage ones. Sales went up. In other words, the program did what it was supposed to.
# 4: Can Urine Rescue Hydrogen-Powered Cars? This was the first time we've ever put the word "urine" in a headline. It was our take on an obscure research paper, and it too climbed Digg. Memo to Staff: Write more about bodily functions! Bottom Line: It takes a lot less energy to split hydrogen out from urea than it does from water and natural gas, meaning the wells-to-wheels energy balance of hydrogen as a fuel could improve substantially.
# 3: Islamic Scholar Suggests Using Ethanol-Powered Vehicles May Be A Sin. This was a genuine breakout hit that we didn't expect. It got hundreds of Diggs in two days, and a gazillion comments. Bottom Line: Sheikh Mohamed al-Najimi suggested that driving or even riding in a vehicle fueled by ethanol could be considered a sin for observant Muslims. Though for some countervailing views, see our followup post.
# 2: Will the 2010 Volkswagen Golf TDI Be Diesel's Biggest Winner? This perennial favorite showed up in our Top Five more than any other post. Bottom Line: The reviews are good, and the base price is just $21,990. We think VW's 2010 Golf TDI will sell well. But carmakers like Audi and BMW without previous U.S. diesel offerings may have a tougher time.
And the single most popular post of 2009 is ... drumroll, please ... this one. Yep, we're scratching our heads too:
# 1: Prius Perks in Peril From Plug-In Privileges? We didn't see this one coming, but this become our most popular article ever on GreenCarReports.com. Zillions of Digg users took it to # 1 as a way to rail against the (perceived) idiocy of so-called Prius perks, hybrids, and all the people who drive them. Bottom Line: Some of the special benefits bestowed by government on the most fuel-efficient hybrids may soon be transferred to fully electric cars.
