There may be a diesel, just not in the US.
Along with an all-new TRD Pro version of the Sequoia, Toyota brought its entire updated TRD Pro range to the 2019 Chicago Auto Show. This included the new 2020 4Runner TRD Pro, which has been updated with Toyota Safety Sense, a new grille to accommodate a radar sensor, push-button start, and two additional USB ports.
During a product press conference with Toyota Motor North America Vice President and General Manager Jack Hollis, it was mentioned that the new 4Runner would feature a new instrument panel.
If you skip to 15:44 in the video, you will see an image of the new instrument panel, which features a unique redline of just 4,500. The 4Runner is currently only available with one engine, a 4.0-liter V6 that revs to 6,000 rpm. Along with a few other outlets, we wondered if this lower rpm redline signified a future diesel variant of the 4Runner.
We reached out to Toyota for comment and Nancy Hubbell, Senior Manager of Product Communications told us, "there are no plans to offer a diesel 4Runner in the US. We’re tracking down the origin of the photo, but it’s not US-specific."
The photo clearly came from somewhere, so perhaps another market will receive a 4Runner with an optional diesel engine. If you watch the video, the picture clearly says "Prototype shown," so the redline could have just been a simple error. With diesel slowly dying (especially in the US), we aren't surprised to hear that Toyota has no plans to offer a diesel engine in the 4Runner. Would it be cool? Sure. But the 4Runner will continue to be one of the best off-road SUVs on the market, regardless of the lack of a diesel engine.
