Volkswagen

John and Helen Taylor are pushing the envelope these days. And it doesn’t involve pressing the petal to the metal for a new speed record, but rather pushing every drop of fuel to squeeze out the most mileage.

The couple is driving a Volkswagen Jetta TDI across the 48 contiguous states with the hopes of breaking the current Guinness World Record for the lowest fuel consumption on a nationwide drive, which is 51.58 miles per gallon.

The team, which is sponsored by Volkswagen, is now 14 percent ahead of the record with an average of 58.24 miles per gallon.

So what are these clever techniques the couple are advocating?
