The higher fees – diesel-fuel taxes may also be increased – would raise as much as $350 million for road repairs next year and about double that by 2018, though nothing has been confirmed as far as a possible vote. Some other states have either considered or enacted similar policies. Most notably, Washington State imposed an additional $100 fee for registration of battery-electric vehicles in 2013.
Such a policy is unlikely to help what's already a tough situation for Ford and GM in terms of advanced-powertrain vehicle sales in the Mitten State. Through April, Ford sold about 20,000 hybrids and electric vehicles in the US, down 29 percent from a year earlier, while GM's hybrid and plug-in vehicle sales plunged 31 percent from a year earlier to just 7,759 units.
