Opinion: Neat technical details, neat truck, but I don’t know if I could get over virtual headlight controls.
Boost is not an on/off switch. The difference between full boost and full power, versus partial boost and far better fuel economy is rather huge. And a vehicle is usually (near) idling along at lower RPMs and only using a fraction of its total torque the vast, vast majority of its time. Takes only roughly 20 HP to main speed on a highway.
And th3 base version (i.e. not massive tires) of the Colorado gets 20/25 MPG, which is better that the 2023 Toyota Tacoma which has a larger naturally aspirated 3.5L V6 and only makes 278 HP and 265 lb-ft of torque max. The Colorado maxes out at 310 HP and a whopping 430 lb ft of torque.

And yet this trucks MPG numbers do not reflect any of that. Aside from that what would the advantage of the turbo 4 be?
