The company announced over the weekend that a new version of its fuel-cell-driven Highlander SUV made a 560km journey from Japan's second city, Osaka, to Tokyo without needing to be refuelled.
After refitting an earlier model, Toyota found that the new Highlander could actually manage almost 900km on a single tank of hydrogen. Fuel efficiency was increased by a quarter, while the tank's capacity doubled and the power-control system was also upgraded to perform better.
Boy racers worried about having to tolerate no-frills clunkers worthy of pre-1989 Eastern Europe will be reassured to hear that the Highlander kept its air conditioning on throughout the journey and averaged 80km/h. Perhaps we can save the planet after all, then, eh?
