Throwback Thursday
In the late 60's, Porsche's obsession with shedding weight was at its peak. During the development of the 909 Bergspyder (a hillclimb car) engineers figured out that to save about 4 lbs, they could use a fuel tank made of titanium, with a rubber bladder pressurized with nitrogen. We don't need no stinking fuel pump!!! #porsche #909 #bergspyder #hillclimb #engineering #obsessed #wtf #mindblown #throwback #thursday #tbt
