Links to the written warranty please or some sources for this (can't seem to find them just by googling, I find only your post when I do). The 5 year/62.5k mile warranty for the Euro market iMIEV (this includes the UK and Norway, see page 8) specifically does NOT cover capacity (page 2): http://www.mitsubishi-cars.co.uk/images/faq/WarrantyTermsandConditionsi-MiEV.pdf The 8year/100k mile US market iMIEV battery warranty specifically does NOT cover capacity (see page 8): http://myimiev.com/forum/viewtopic.php?f=5&t=15&view=previous The Norway and UK battery/powertrain 5 year /100k km warranty for the Transit Connect Electric makes no mention of coverage of battery capacity (only defects): http://www.transitconnectelectric.net/pdf/dealer_admin/2011_LPW_Norway.pdf http://www.transitconnectelectric.net/pdf/dealer_admin/2011_LPW_UK.pdf The 5 year/ 60k mile warranty on the US spec Transit Connect Electric is similar: http://azdtec.com/dealer/support/TCE/PDF/107388-A%20(English)ReadOrder.pdf And like I said, the worse case degradation for Tesla's cells to 70% is 3-5 year 40k/60k/80k mile. They numbers you posted seem to correspond well to my prediction. http://www.teslamotorsclub.com/showthread.php/7747-Standard-Warranty-Revealed?p=171114&viewfull=1#post171114 Like jerry33 said, here in the US, if your battery warranty was only 63k miles, you would be laughed at (I'm assuming the cars you linked also have a defect warranty that's longer than that). My question is how receptive would people be if Tesla provided a 3-5 year 40k/60k/80k mile warranty to 70% degradation? Would that address their concern or would it cause more concern?
