I beg to differ on that one.Bilmat said:Which is evidence that its targeted buyers suffered from range anxiety.
Answering my own question after doing some digging (and calling the Spark EV customer line,) from http://www.chevrolet.com/owners/warranty.html:Pegasus said:can you post a copy of the battery and powertrain warranty terms and conditions?
This is specifically for the Volt but the Spark EV team told me the Spark EV's policy is the same, except that it's up to 35% degradation, though that's a doomsday scenario. So it's warranted to have at least 65% of original capacity for 8 years/100K miles (10/150K in CA?,) which is 13.65kWh (65% of 21kWh,) so roughly 53 miles (65% of the nominal 82.) That'll still work fine for me. (My last electric car had a 50 mile range in the best case, though that used lead-acid batteries.)This Voltec warranty covers repairs to correct any Voltec component defect related to materials or workmanship occurring during the 8-year/100,000 mile term for the following:
Propulsion Battery Warranty Policy
Like all batteries, the amount of energy that the high-voltage “propulsion” battery can store will decrease with time and miles driven. Depending on use, the battery may degrade as little as 10 percent to as much as 30 percent of capacity over the warranty period. A dealer service technician will determine if the battery energy capacity (kWh storage) is within the proper limit, given the age and mileage of the vehicle. Your Volt battery warranty replacement may not return your vehicle to “as-new” condition, but it will make your Volt fully operational appropriate to its age and mileage.
