FUEL EFFICIENCY
Here's a guy, Ernie Rogers, who gets 50 to 61 mpg with his Volkswagen a 2003 VW New Beetle TDI diesel with a newly-designed wing attached at the rear to the trunk lid | The wing improves fuel economy by 5% to 8% by lowering aerodynamic drag |
His website,
max-mpg.com documents a trip from Salt Lake City to Alaska made last summer | Once in Montana he'd converted to using biofuels | A more recent posted he'd made on
Renewable Energy - a Yahoo Discussion Group, asserts that he'd gotten 61 mpg on a trip from Provo, Utah to Lake Tahoe, Nevada |
On the blog portion of his website Ernie posits that
we can build more efficient engines and alludes to some real-time changes that can be made right away | He doesn't update the blog often, but the things he mentions remain timely |
