Fuel cell Colorado clean AND mean

NZ4WD - - NEWS -

Build­ing an all- new, hy­dro­gen fuel cell elec­tric ve­hi­cle is it­self a daunt­ing task. Engi­neer­ing one that is of­froad ca­pa­ble pre­sented a new level of chal­lenges for the team of en­gi­neers and stylists who un­veiled Chevro­let’s Colorado ZH2 con­cept truck at the SEMA show last year. “The ZH2 in­te­grates the strong foun­da­tion of the Colorado mid­size pickup ar­chi­tec­ture with GM’s ad­vanced hy­dro­gen fuel cell propul­sion tech­nol­ogy,” said Jim Camp­bell, vice pres­i­dent, Chevro­let Per­for­mance Ve­hi­cles and Mo­tor­sports. “It com­bines the lessons Chevro­let has learned dur­ing 3.1 mil­lion real- world miles of test­ing hy­dro­gen fuel cell- pow­ered ve­hi­cles. It also re­flects our com­mit­ment to ex­pand­ing Chevro­let’s per­for­mance en­ve­lope off- road.” The Colorado ZH2 is no show pony, a demon­stra­tion ver­sion set to be tested by the US Army later this year to eval­u­ate the ef­fec­tive­ness of a hy­dro­gen fuel cell-pow­ered off- road ve­hi­cle in mis­sion set­tings. The bold ap­pear­ance of the Colorado ZH2 was driven by the pack­ag­ing re­quire­ments for the fuel cell sys­tem, sta­tion­ary power gen­er­a­tion and chas­sis hard­ware nec­es­sary for off-road per­for­mance. At the rear, the ZH2 fea­tures a clamshell cover that in­te­grates air in­takes feed­ing ra­di­a­tors hon­ey­combed be­hind the rear doors. The chas­sis was de­signed and en­gi­neered for proper off-road use as in­di­cated by the 37-inch BF Goodrich tyres mounted to 17-inch bead­lock-equipped wheels. Power is trans­ferred from the 93 kW fuel cell sys­tem to the 132-kW elec­tric mo­tor, which pro­duces 236 lb.-ft. of in­stan­ta­neous torque. That torque is then de­liv­ered to the trans­fer case and a four-wheel drive sys­tem with elec­tronic lock­ing dif­fer­en­tials front and rear.

Chevro­let’s fuel-cell fu­ture is look­ing good.
