What does a PHEV become when it grows up? And do we need yet another electrified-vehicle acronym? Technically, a hybrid with a plug is a PHEV, but some argue that a vehicle with a substantial electric range is a different animal. Chevy called its Volt an EREV, and Seattle-based startup Maxwell Vehicles is calling its plug-in cargo van conversion an RHEV (range-extended hybrid electric van).
Maxwell’s RHEV is a Dodge RAM ProMaster upfitted with a PHEV powertrain manufactured by GM (thus it’s a hybrid in more ways than one). It sports an 18 kWh battery pack and a 120 kW electric transaxle, and delivers 40 miles of electric range.
