Although Switzerland borders Austria, the most faraway places of the two countries are almost 1000 miles apart. The quickest way to get from Les Rangiers to the Gaisberg is via Munich, but the most picturesque route takes you through Voralberg and Tyrol, through the Arlberg, and past the Brenner Pass. Since we are traveling in convoy with a chase car, the pussy-footed Boxster S returns a hyper-frugal 22 mpg. When it's let loose to race back from Salzburg to Zuffenhausen, the car increases its consumption to 15 mpg. While the fuel tank's capacity is unchanged at 16.9 gallons, the trunk volume has been increased to 9.9 cubic feet by replacing the space-saver spare with a can of sealant and a compact electric compressor for tire inflation. Despite a wider body and fatter wheels that enlarge the frontal area, the drag figure of the Boxster S was pared down from 0.32 to 0.30. At the same time, lift was reduced by 30 percent thanks to a flush-fitting underside, ground-effect aprons, and a lot of wind-tunnel work aimed at improving directional stability at high speed.
