超信地回転

信地回転：
skid-steer

超信地回転（戦車等の「その場」旋回）：
Skid-steer loaders are capable of zero-radius, "pirouette" turning, which makes them extremely maneuverable and valuable for applications that require a compact, agile loader. Wikipedia, skid-steer loader

pivot turn; swivel turn

その場回転（船舶）：
pinwheeling

信地旋回は馬術用語が語源らしい。ピルエットの訳語は「後肢旋回」らしいが、超信地旋回もpriouetteでいいか？

Four-wheel steering (4WS): from Quadrasteer v2.0
At high speeds, Quadrasteer allows the rear wheels to turn slightly in the same direction as the front wheels, which greatly improves tracking with or without a trailer. That was the primary goal of the engineers at GM when they started working on four-wheel-steer (at the time, Delphi was a part of GM), and it was reached.

But it's at low speeds that any four-wheel-steering system has its most dramatic affect, since it enables the rear wheels to turn 12 degrees in the opposite direction of the front wheels. That lets the vehicle make tighter turns, such as when cornering or getting into a tight parking space. The turning diameter of 2500 models with Quadrasteer is reduced 21 percent, from 49.6 feet to 37.4 feet, which is in the same range as a small car like the Saturn coupe.
