CMU study concludes diesel and hybrid vehicles can retain more value than PFI gasoline vehicles despite higher new car price

A new Carnegie Mellon University study released at the Washington Auto Show finds that for passenger cars, aadvanced vehicles with higher fuel economy—i.e, turbocharged direct injection diesels or hybrids—retain more value than a paired conventional vehicle—i.e., port fuel injected (PFI) gasoline—during periods of higher fuel costs.
