Car of Tomorrow

[Bio]

В каком смысле не отвечает? А это тогда что?

Drafting, which looks like tailgating or slipstreaming, occurs when a second car tucks closely behind the first, filling part of the vacuum. The car in front loses some of the drag at its rear. The second car still has a vacuum at its rear, but now has less air resistance in front. As a result, both cars quicken a bit — the two combined speed a few miles per hour faster than either can alone. This push-pull effect is stronger the closer the second car gets to the first. Indeed, the second may even touch and push the first in a tricky maneuver called "bump drafting." But slipstreaming so closely hinders airflow into the trailing car's radiator and can cause its engine to overheat. Most drafting calls for a half to a full car length between the two cars. (In contrast, open-wheel, motorcycle, and bicycle racers do not gain extra speed by drafting, because a trailing racer does not generate the forward aero push that stock cars do.)
