Vehicle spec sheets aren't always 100 percent accurate. Sometimes, in the case of the Chevrolet Corvette Stingray, this is a good thing. BMW's flagship coupe, the M8 Competition, has also proven to be quicker than the German automaker claims.

But when it comes to the stunning Ferrari F8 Tributo, the actual outcome doesn't diverge from Ferrari's claims in a positive sense. YouTube channel DragTimes decided to put the F8 Tributo up against the McLaren 720S, but when weighing the F8, they found it to be significantly heavier than what Ferrari claims.

According to Ferrari, the F8 Tributo has a curb weight of 3,163 pounds, but when checked on the scale at around the 06:35 mark, the F8 was actually found to weigh 3,453 lbs. That 290-pound difference is significant, especially for a performance car like the F8.

The YouTuber confirms that none of the options fitted to this F8 Tributo, such as the upgraded stereo, could possibly weigh that much. This particular example's fuel tank was also only under a quarter full, so that doesn't explain the difference either. Wearing Toyo tires and slightly heavier wheels, these items add only around 12 lbs to the total.

Could the scale be totally off? Apparently not, because when the McLaren 720S is weighed on the same scale later, it came in at 3,158 lbs, which is just 30 lbs more than what McLaren claims. Clearly, the F8 Tributo is a lot heavier than Ferrari says it is. The difference in weight between the two cars isn't surprising since the 720S features a full carbon fiber monocoque, but the discrepancy between the weight here and Ferrari's official figure is curious.

It doesn't seem to affect the F8's performance, though, as it recently out-muscled a Porsche 992 Turbo S Cabriolet, even though the latter has a quicker claimed 0-60 time. Clearly, that 710-horsepower twin-turbo V8 is a beast, whether carrying an extra 300 lbs of mystery weight or not.
