Corola H2 byla nasazena do z\u00e1vodu jako prvn\u00ed v\u016fz na pohon zkapaln\u011bn\u00fdm vod\u00edkem. Na okruhu Fuji absolvovala celkem 358 kol, co\u017e je vzd\u00e1lenost rovnaj\u00edc\u00ed se 1634 km.

Toyota ji\u017e podnikla dal\u0161\u00ed krok k dekarbonizaci prost\u0159ednictv\u00edm motoristick\u00e9ho sportu. Hlavn\u00ed v\u00fdhodou kapaln\u00e9ho vod\u00edku je jeho del\u0161\u00ed dojezd.

Na rozd\u00edl od plynn\u00e9ho vod\u00edku nevy\u017eaduje kapaln\u00fd vod\u00edk vysok\u00fd tlak, co\u017e umo\u017e\u0148uje v\u011bt\u0161\u00ed volnost p\u0159i konstrukci n\u00e1dr\u017ee a potenci\u00e1ln\u011b otev\u00edr\u00e1 v\u00edce prostoru na zadn\u00edch sedadlech.
