Just before Ford unveiled the new Bronco this summer, Jeep revealed the Wrangler Rubicon 392 Concept, a Wrangler concept powered by a 450-horsepower, 6.4-liter V-8. It felt like a bit of a stunt to steal some of Ford’s shine. But, uh, it’s happening. For real. Jeep is actually shoehorning a 6.4-liter V-8 under the hood of the Wrangler Rubicon in response to what it claims is customer demand.
