Following up on this, there was some extended work that had to be done on my 4Runner (dealer's fault) so I returned the Colorado to Enterprise and the dealer had to give me a loaner.
Low and behold, it was a 2018 Tacoma SR5 4x2 V6. Couldn't be more comparable to the Colorado I drove. So, I spent two weeks behind the wheel of the Chevy and two and a half weeks behind the wheel of the Toyota.
Excuse my french *puts on flame suit*, but the Tacoma is a flat out piece of garbage and the only way Toyota is selling any of them is the name alone. I come from a Toyota family, I've been employed by Toyota, I've only ever driven Toyota products, and I will sit here and tell you the Colorado is a vastly superior truck to the Tacoma in about every conceivable way. Only two merit points I can give the Tacoma are the TSS+ and perceived reliability, but I'm not sure that's worth much these days with the well documented reliability issues this generation has experienced.
The Colorado's 3.6L/8AT combo is not only an indisputably superior powertrain with regard to power delivery, drivability and efficiency, but it is so much smoother and more refined that it makes that iteration of the 2GR-FKS feel like it was dug out of the dirt in a landfill. Driving the Colorado like a reckless teenager, I got 20.7MPG. The Tacoma got 16.7MPG. My 2016 Limited (full time) 4x4 returns 16.5MPG average. These are all manual calculations.
I got out of the Colorado and directly into the Tacoma, turned the key, and it felt like starting a lawnmower because there are so many vibrations in the drivetrain, not to mention it being loud and lacking what many would deem modern NVH standards. I can't believe I'm talking about how much more refined and well built a Chevrolet feels compared to a Toyota.
The Colorado motor is great - it's predictable and smooth throughout the power band, not to mention linear and very powerful. The Tacoma is gutless and frighteningly dead under 4k RPM, at which time, the motor magically comes to life with a scary force that throws you forward until 6k RPM. It is enough force to break the rear wheels free at 40MPH or so. Try pulling out of a line of traffic, putting your foot down, inching out and then hitting 4k RPM and taking off like a bat out of hell with the wheels struggling for traction. Welcome to driving the Tacoma in city traffic - it feels out of control and unmanageable in some scenarios.
The Tacoma's 6AT has this weird characteristic with kick down where when you're coasting to a stop, as the transmission drops gears, it lurches you forward so much so that you feel like you need to hit the brakes. The Chevy's 8AT is, again, much superior.
The only two things I like about that powertrain (Tacoma's 2GR-FKS) more than the 1GR is:
- Faster gear changes (our 5AT is painfully slow and clunky at this - the 6AT is better, but modern 8ATs are MUCH faster)
- Better passing power on the highway (with this being a high revving motor, merging and overtaking on the highway is a lot easier than in the 4Runner).
I can say that if the 2GR-FKS/6AT goes into the 4Runner as it is, I would probably not buy it. The outdated 1GR with a confused, clunky 5AT is easier to drive because it's got the power band for a truck/SUV.
Last but not least: While the interior of the Colorado is not visually appealing to me, it feels like comparing an S Class to a Fusion when parked next to the Tacoma. I would describe the interior of the Colorado as decent but outdated looking. The interior of the Tacoma is just flat awful with slabs and valleys of hard plastic everywhere. It's not outdated - it's ugly. This one had 3k miles on it and it had a rattle on the passenger side of the dash, another behind me in the rear driver's side door, and the front passenger door rattled when the window is down - it sounded like glass/metal contact. Not to mention how much better the sound insulation is in the Colorado compared to the Tacoma.
I hope the upcoming Tacoma refresh is significant, and I hope the 4Runner doesn't ever get this motor. The Colorado is already a much better truck, but we now have the Ranger coming as well as the new Gladiator. Toyota has to get on the ball.
