There’s no doubt that the four wheel drive touring car market is hot, especially when there’s nitro involved. So it’s no surprise that HPI revamped its RS4 3 line, and renamed it the RS4 3 Evo. While the car is targeted to the beginner and intermediate driver, that doesn’t mean it feels like it’s lacking anything when it comes to features.

So I guess now that I mentioned features, you want to know what some of those are. While I’ll give a full rundown of the components of the Evo later on the review, it wouldn’t hurt to mention a few now to whet your appetite. How does an included rotary starter, a completely redesigned motor, and a two speed transmission sound? Is your interest peaked yet? I thought it would! If that wasn’t enough, they have also went through their lineup of stock bodies and offer some very sharp looking options for you to choose from as well.

I can’t wait to fire the RS4 3 Evo up and take it for a spin. I loved this chassis layout when I reviewed the MT2 18SS several months back, and I am curious to see how well it’ll work as a four-wheel drive touring car platform. After pulling it out of the box, I can see that the quality I’d expect from HPI is there, now let’s see how the looks translate to performance once I fire the motor up.

  1. Is it just me or does this review seem like it is reaching and nothing more than cheap filler for a new homepage.
    The car is 10 years old and the review is written as if it was purchased yesterday.

    If you are going to write an article and claim it was written on April 9th 2015 at least make it relivent to the times. As it is it feels like you are trying to be something you are not.

    • Thanks for the comment. So as not to confuse anyone, this is filed as “ARCHIVE” and titled “HPI Racing Nitro RS4 3 Evo RTR – Circa 2005”. It’s meant to be a reminder of some reviews from our past; It’s fun to look back sometimes.
