We have a suspicion that a diesel Tundra is in the works.
Toyota currently sells no diesel-powered vehicles in the US, and that seems unlikely to change if you look at the last few years. The automaker made moves to kill off diesel-powered passenger vehicles in Europe in 2018 before ending its partnership with Isuzu to develop new diesel engines. Then last year, we were told not to believe any rumors of a diesel-powered 4Runner. However, Toyota USA's YouTube channel has been posting a number of videos explaining how a diesel engine works (check out the latest in the series below), and this got us thinking: Is Toyota planning to bring oil-burners back, and more specifically, is this the beginning of preparing us for a diesel Tundra?
This would make sense, as Toyota has been teasing us with images of the 2022 Tundra for a little while, showing us the exterior design and highlighting the cabin with its numerous new features, as well as some returning features that buyers of previous models have loved. Despite revealing a lot, the one aspect that hasn't been covered in much detail is the engine, although we have seen teaser shots of it. We also know that there will be a TRD Pro version of the truck, so there are myriad reasons why the idea of a diesel Tundra could be more than a pipe dream.
We'll have to wait for the full reveal to confirm the existence of a diesel Tundra, but for now, we're pretty sure that we can expect a new twin-turbo V6 gasoline engine that will produce around 450 horsepower and 500 lb-ft of torque with the aid of a hybrid system, meaning that the culling of V8 engines from the lineup will result in a power increase. In the current model, the naturally aspirated 5.7-liter V8 puts down a maximum of 381 hp and 401 lb-t of torque. We assume that, if a diesel does come, it will produce roughly as much power as the V8, but with more torque.
