In any automotive era, the hot-rodders will eventually rise to the bait, as they have with the 2018 Chevrolet Tahoe RST Edition with its 6.2L Performance Package.

It doesn’t matter whether it’s post-World War II gear-heads stuffing V8 engines into 1930s Ford Model A coupes, or modern street racers hopping up old Honda Civic Si hatchbacks. Someone will always figure out a way to dredge artistry and performance out of pedestrian machinery.

That’s expected, but the hop-up imperative has become institutionalized. The German luxury manufacturers — Mercedes-Benz, BMW and Audi — all have performance divisions to inject their already hot machines with ever more power.

Now, with the new Tahoe RST, Ford’s Raptor pickup truck and the mind-boggling Jeep Grand Cherokee Trackhawk from Fiat Chrysler Automobiles, the blastoff mindset has insinuated itself into the biggest of the big vehicles that were originally designed to simply tow, carry and haul lots of stuff on and off the road.

Which brings us to the Tahoe RST (rally sport truck), a monster SUV based on the Chevrolet Silverado full-size pickup truck. It comes with a 420-hp 6.2-liter V8 engine that delivers 460 lb-ft of torque through a new 10-speed automatic transmission.

It has four driver-selectable drive modes: two-wheel drive for leisurely highway cruising, full-time all-wheel drive for nasty conditions, and locked four-wheel drive with high and low ranges for off-road forays. In short, there’s not much it cannot handle. Moreover, it can tow loads up to 8,100 pounds. 

Equipment also includes GM’s magnetic ride control, an active suspension setup that takes readings of road conditions and electronically adjusts the shock absorbers in milliseconds. It works in concert with gloss black 22-inch aluminum wheels.

Still, don’t expect a cushy ride. This fundamentally is a truck outfitted for performance despite its monster size, so the ride gets harsh and choppy except on pool-table smooth surfaces. If you’re a truck person, you’ll grin from ear to ear. If you have more of a comfortable sedan or crossover SUV orientation, it likely will produce a frown.

The biggest drawback — or enhancement, depending on your preference — of the Tahoe RST Edition is its sheer size. It stretches 17 feet in length and weighs 5,631 pounds. With that big V8 engine it doesn’t bow to anything — zero to 60 miles an hour arrives in less than six seconds — but don’t expect to toss it around like a sports sedan or performance-oriented crossover.

Nope. The RST works best when it is driven deliberately, in slow motion with well-planned moves. That way, with practice, its bulky dimensions come under control. Moreover, it is surprisingly docile in urban traffic given the power lurking under the hood.

Punch the pedal at a stoplight and all those horses will pin you back in the seat. Choose either two-wheel drive or automatic all-wheel drive. Either way, the RST Edition gets off the line with little or no wheel spin. 

For all of its truck and performance credentials, the Tahoe RST Edition comes equipped as well as many luxury cars. There’s tri-zone automatic climate control, leather upholstery, power tilt-and-telescoping steering wheel, power adjustable pedals, heated and ventilated front seats, rolling WiFi, head-up display, wireless smart phone charging, and an eight-inch center screen for navigation and infotainment functions,   including Apple Car Play and Android Auto, and a rear-seat entertainment system.

None of this, of course, comes cheap. The tested RST Edition had a starting price of $66,425. With the equipment mentioned, along with other options, the bottom-line sticker price came to $78,450—not a territory for many middle-class buyers.

However, if you are not captivated by the awesome performance, which by the way takes its toll in fuel economy, there are lesser Tahoe versions that would be more friendly to the family budget. The RST has a city/highway/combined fuel consumption rating of 14/22/17 miles to the gallon.

The tester was a seven-passenger model with two captain’s chairs in the second row. Working with the power tailgate raised, a touch of a switch folds the rear seatbacks and the third-row seats to produce a flat load floor with nearly 98 cubic feet of cargo space. 

Seats in the first two rows deliver comfort and support. But the  third-row seats are impossible for anyone but small children, watermelons or backpacks. There’s little knee room and no help because the second-row seats do not adjust fore and aft.
