Mae'r Rasa, sy'n ddyluniad newydd, wedi derbyn cymorth grant a chefnogaeth gan Lywodraeth Cymru, ac mae wedi'i adeiladu i fod mor rhad ar ynni â phosib. Mae'n defnyddio 8.5kW o gelloedd tanwydd hydrogen yn hytrach na'r 100+kW o gelloedd tanwydd a ddefnyddir mewn cerbydau hydrogen eraill. Mae gan y Rasa siasi carbon cyfansawdd a phaneli ffibr gwydrog, ac mae'n pwyso 580kg. Mae'n gallu gwneud 250mpge ar y cylch trefol swyddogol.
Purpose designed from the ground up, with grant support and sustained collaborative assistance from the Welsh Government, and built with ‘ultimate vehicle efficiency’ in mind, the Rasa uses an 8.5kW hydrogen fuel cell rather than the 100+kW fuel cell used in other hydrogen vehicles. With a carbon composite chassis and fibre-glass body panels, the Rasa weighs 580kg and is capable of 250mpge on the official urban cycle.
