Big Mack with a side or­der of turbo

The Witness - Wheels - - MOTORING -

TRUCKS that don’t guz­zle diesel were all the rage at the WasteExpo 2016 re­cently held in Las Ve­gas, and fore­most among these green trucks were the elec­tric Mack refuse re­moval trucks.

De­signed as an al­ter­na­tive driv­e­line, the Wright­speed Route give the big Mack a side or­der of turbo to ex­tend the range of the elec­tric ve­hi­cle pow­er­train as far as the driver can get.

The Wright­speed Route pow­er­train uses elec­tric­ity to de­liver 100% of the ve­hi­cle’s propul­sion. The sys­tem fea­tures an ad­vanced plug-in ca­pa­ble bat­tery pack that en­ables a purely elec­tric range of up to 38 kilo­me­tres. When the bat­tery charge is de­pleted, an 80 kW, fuel ag­nos­tic Ful­crum Tur­bine Gen­er­a­tor, which can op­er­ate on nat­u­ral gas or diesel fuel, recharges the bat­ter­ies, en­abling Routee­quipped ve­hi­cles to have un­lim­ited range with re­fu­el­ing.

Ad­di­tional recharg­ing comes from the Route’s 730 kW re­gen­er­a­tive brak­ing sys­tem, which gen­er­ates elec­tric­ity as the ve­hi­cle comes to a stop. Elec­tric­ity from the bat­tery pack pow­ers four geared trac­tion drive elec­tric mo­tors, en­abling the Route pow­er­train to power ve­hi­cles up to 33 tons on grades as steep as 40%. With full torque avail­able from zero rpm, the Route driv­ing ex­pe­ri­ence is com­pa­ra­ble to diesel-pow­ered trucks. — WR.
