Is It Better To Buy A Late Model Gen 3 or Early Model Gen 4 Toyota Prius?
I recently came across a question from a potential Prius owner. They asked, 'Should I buy a 2015 or a 2016 Toyota Prius?' Initially, I thought this would be a no-brainer; a Gen 4 is better than a Gen 3, right? Then I got thinking, what are the differences between the two?
I concluded that it would be helpful for people looking for a newer Prius to know some fundamental things. If you can make an informed decision, it may help with you enjoying the car more.
Similarity One: The Engines Are Nearly Identical
While it is commonly understood that early Gen 3 Prius is plagued with head gasket issues, Toyota seems to have figure out the fix for that.
Fundamentally the 15' and 16' Prius are the same engine-wise. The good thing is the issues that have been a significant demise to the early Gen 3 are not nearly as prominent.
Similarity Two: Hybrid Battery Is The Same On Some Models
For Generation 4, Toyota introduced a new battery option, Lithium-ion. Generation 3 did not have this option. However, on some Gen 4, the battery pack was still the same 201.6v nickel-metal hydride.
There are advantages to the lithium battery, but overall you are not missing much. EPA ratings between the LIthium and non-lithium cars are pretty much NIL.
If you can get a killer deal on a 2015 Prius, go for it. Sure the body styles are different between 15 and 16 model years, but overall the Gen 4 Prius was a Gen 3 on some level with new tech and more options.
Both are great cars, but I do not think you are necessarily missing out by getting into a late model Gen 3.
That is all for this one. I hope you can find what you are looking for in a Prius. I look forward to seeing you in the next article.
