Agar mudah dikendalikan saat di trek, Adhi memasang transmisi otomatis di mobilnya. "Transmisinya pakai Power Glide otomatis 2 speed," papar Adhi.

Wah, dari mana ini?
Dari FAA, pengatur penerbangan Amerika:

Basic Flight Maneuvers
A glide is a basic maneuver in which the airplane loses altitude in a controlled descent with little or no engine power; forward motion is maintained by gravity pulling the airplane along an inclined path and the descent rate is controlled by the pilot balancing the forces of gravity and lift.

Nah, power glide berarti yang pertama itu: loses altitude ... with little engine power. Mesinnya masih menyala, namun putarannya dikurangi. Keterangan berikut akan lebih meyakinkan:

https://inspire.eaa.org/2019/04/25/losing-power-on-takeoff-w...
At an altitude of approximately 1,500 feet AGL, align your aircraft with a straight stretch of road. Note a starting reference point and then reduce power to idle and see how far you can glide until losing 500 feet. Climb back to 1,500 feet and realign with the road and reference point. Reduce the power to 1800 rpm and then measure and compare the glide distance to that of the idle power glide.

Boleh dikatakan, kutipan kedua ini mengisyaratkan bahwa sebenarnya power glide berasal dari idle power glide alias melungsur bertenaga mesin tanpa beban atau melungsur bertenaga senggang.

Wow, tambah panjang...
Itulah kenapa cukup melungsur bertenaga.

melayang turun tidak saya favoritkan karena panjangnya, namun mungkin berguna terhadap editor yang tidak suka kata-kata yang jarang dipakai.

Atau barangkali versi kata bendanya: lungsuran bertenaga / layangan turun bertenaga.
