EcoModder's 25 most popular topics/threads of 2018!

Another lap around the sun, so it's time again for this fun re-cap!

Rule change: I realized the query we were using to find the topics for this list handicaps topics started later in the year. So we expanded the search to include some topics that were started in Nov & Dec of 2017 as well.

Notable this year:
  • PRIUS GUTS RULE! This is the 3rd year in a row that one of the very top projects is about sticking a Prius drivetrain/chassis into a classic vehicle.
  • For the first time ever, an "UN-ecomodding" project made our list (1st gen. Honda Insight engine swap)
  • Also for the first time, one of our most active topics was started by a spammer (who was subsequently banned)!
See also:



Without further ado...


1) Hybrid Hot Rod 2.0 - The Pria Ghia




It's safe to say Prius drivetrain/chassis swaps with classic cars is a thing. Hoopie is doing it again, this time with a VW Karmann Ghia.

9) Is America ready for 4-cylinder full-size pickup trucks? Because they're here (GM)




It's a big, 2.7 L four, with lots of fuel-saving tech. It even has a cylinder de-activation mode, capable of running on 2 cyls.

Yet when the EPA ratings were announced, the numbers were underwhelming.

14) The Mitsubishi Mirage is the WORST CAR you can buy!

========================

This spammer went above & beyond the usual pattern, which is: picking a random username; then posting 5 utterly useless comments in existing threads so they can embed their spam link in post #6.

Particularly funny because of the username chosen -- "coroplast"! Almost makes me think they researched their target audience! And then this random thread topic was fairly appropriate for this group, not entirely useless.

Most effort put in by a link spammer, ever.

Wow, yeah that was a lot of effort. I mean, the username was appropriate for the forum, and not just something you'd come up with by casually browsing topics either. Then they posted a coherent thread and pointed out a fairly bad car.
