Hennessey Straps a Supercharger to the Tahoe and Suburban, Then Sends Them to the Gym

The Chevrolet Tahoe and Suburban have long been the automotive equivalent of a teddy bear — big, cuddly, and perfect for hauling kids, groceries, and golden retrievers. But Hennessey looked at that plush family hauler and said, “Right, enough of that.” It was time to throw a leather jacket on the bear, ink a tattoo down its bicep, and unleash it onto the highway in a cloud of tire smoke. The result? The new Hennessey H600 — a monstrous SUV with 625 horsepower, 633 lb-ft of torque, and a soundtrack that growls louder than a grizzly with a sore head.

This isn't some backyard tuner job. It's an official partnership with General Motors, which means you can walk into a Chevrolet dealership and order a factory-backed SUV that’s been given the full Texas treatment: a supercharger, performance exhaust, Brembo brakes, lowered suspension, and 24-inch black wheels. And yes — it comes with a full warranty. Like buying a new microwave... except it weighs 2.7 tons and might outrun your neighbour’s Mustang.

John Hennessey himself says his family has owned more Suburbans than most people have socks, and now he just wanted to make the ultimate one — something a little louder, faster, and frankly, a lot more fun. And that’s exactly what this is: a family SUV that launches, roars, corners, and still fits a small army of children and their football kits.

Only 100 of these beasts will be built. So if you want an SUV that looks like a government agent’s ride, drives like a Shelby GT500, and sounds like the devil gargling thunder, you better call Hennessey — or walk into a Chevrolet dealer in the States — fast. These things will go quicker than hotcakes. Or rather, hotcakes with a V8 and a Magnuson blower baked in.
