33 degrees. That’s the angle of repose for a hill of loose cinder, like the one found on Maui’s Hana Ranch. It’s the greatest angle at which the brown, sharp volcanic rock will naturally stack itself into a pile. And it was deemed, by Toyota, as decidedly too tame. Cue: backhoes and course builders, fashioning a freshly packed 45-degree slope rising from the earth like a black-diamond ski run for trucks. All that, and I didn’t even get to drive it myself.

“It’s like cruise control for off-roading,” Chief Engineer Mike Sweers said before I activated Crawl Control in the Tacoma TRD Pro. “It will make the weekend warrior look like an expert to his buddies.” (Sweers also mentioned that Crawl Control could unstick a car stuck up to its axles in sand.) The feature, which adjusts the level of acceleration and braking for each individual wheel, automatically carried me down the harrowing slope, free of drama. I handled the steering; the tech handled the grade. Off-road purists may cry foul, I suppose, but they are more than welcome to keep the feature turned off.
The Tacoma is good for plenty with all the tech off, too. It was more than capable in 4Hi, zooming around a mud track high on a bluff over the Pacific. It was comfortable and peppy navigating around the slimy dirt roads of Hana Ranch too, flanked by fields of mango and papaya. We had no trouble pounding it through a menacing and seemingly impassable creek bed full of rock outcroppings.
