AFAIK, none. I searched a lot but there are none. CarSort (website) gives you some information but it is not at par with the vehicle manufacturer's website. Frankly, car specification data is too much to be displayed on a phone.
KBB has database but except the current year, none is available for the user. kbb app is pathetic.
Consumer Report should have the best database but with their business model, I doubt they will make an app. (They actually should)
Whatever other websites there are, cars.com, msn auto etc. etc. have extremely rudimentary information, so IMO, they are useless.
