Ford released performance figures for its Ford GT a few hours ago, with the top speed of 216 miles per hour. What's really impressing here is not the speed but the fact that it's Blue Oval's647-horsepower supercar bests the benchmarks from McLaren and Ferrari on a track. 3.1 seconds better than a Ferrari 458 Speciale. Ford's claim that the GT has a dry weight of 3,054 pounds. Dry weight is the alternative truth of the automotive world, in that it has no bearing on reality. Technically it refers to a car's curb weight with no fluids whatsoever, which is almost impossible to prove and can differ greatly from the rolling curb weight. Ferrari and McLaren list non-dry curb weights of 3,075 and 2,927 pounds, respectively. The latter is listed as DIN, or German standard weight, which includes 90 percent of the fuel. US-spec cars are often heavier due to crash regulation necessities like side-impact airbags.
