Land Rover Defender V8 vs. Jeep Wrangler Rubicon 392 | V8 4x4s square off on paper

Land Rover pulled the sheet off its 2022 Defender on Wednesday, introducing another high-performance V8 to the off-road segment. This time, it's a 5.0-liter, supercharged V8 boasting 518 horsepower. It will be available in both the Defender 90 and 110 models. In the former, Land Rover says it can crack off a 0-60 run in just 4.9 seconds on its way to a top speed of 149 mph. The long-wheelbase 110 will be a bit slower, but "slow" probably isn't the right adjective to use here at all.  But Land Rover isn't the only automaker offering a high-performance variant of its off-road SUV. While Jeep may have been sneered at for presenting the 2021 Wrangler Rubicon 392 on the heels of the 2021 Ford Bronco's introduction, it starts to make a lot more sense in this context. There's reportedly a high-output Bronco on the way, too, so call Jeep the dinosaur of the group all you want, but you can't put a price on being first. Well, you can, actually, but that's not the point.  Thankfully, both Land Rover and Jeep have provided enough specs for us to rough out a comparison chart. Since the Rubicon 392 is offered only in four-door guise, we're looking at the long-wheelbase Defender 110 as its direct competitor here. Have a look: There are a few caveats to mention off the top. For starters, we don't have an official curb weight for the V8-powered Defender yet, as Land Rover has not finalized its U.S. specs. We used the European figures (as provided by a spokesperson), which we expect to be accurate within about 50 pounds. The 0-60 time provided by Land Rover was for the Defender 90, which is smaller and somewhat lighter than the 110. When equipped with the inline-6, the Defender 110 is about a tenth of a second slower to 60 than the Defender 90, so we figure it should be roughly the same for the V8.  While the Defender has nearly 50 horsepower on the Wrangler, that advantage disappears thanks to the Land Rover V8's monster weight penalty, which will fall somewhere between 600 and 700 pounds depending on equipment. Yikes. On the flip side, however, the Land Rover has the edge in top speed, and it's not even close. Chalk that up to the tires, we suspect. We know for a fact that the Rubicon 392's all-terrains dictate its speed limiter; Jeep's own engineers told us as much. This could make for a (hypothetically) interesting drag race, as the Jeep's advantage off the line may evaporate once triple digits come into play.

Build a Jeep Gladiator 392 next? The Hummer H3T Alpha blazed the trail

The 2021 Wrangler Rubicon 392 will combine the go-anywhere capability of a Jeep's iconic off-roader with the grunt of a V8 for the first time in decades. As cool as that is, we can't help but think Jeep is missing out on a huge opportunity to pair that 470-horsepower, 6.4-liter Hemi V8 with the Wrangler's pickup cousin, the Jeep Gladiator, in the form of a Mojave 392.  Autoblog took part in a media Q&A session with Jeep ahead of the Rubicon 392's announcement in which the company's product higher-ups said that there are currently no official plans to build a 392 variant of the Gladiator pickup. But whether or not Jeep has plans, it certainly has precedent, and from our perspective, a market.  Rewind to 2008, better known as one of the worst possible years to introduce a gas-guzzling, V8-powered pickup truck. Enter the 2009 Hummer H3T Alpha, the first variant of Hummer's midsize truck/SUV hybrid to be offered with a 5.3-liter V8. The 300-horsepower small-block was an upgrade to the sturdy but relatively uninspiring 3.7-liter inline-5 that the H3 lineup had inherited from its midsize pickup platform mates.  As our Jeremy Korzeniewski noted in the Rubicon 392's introductory piece, an open-top Jeep has not been offered with an optional V8 for as long as the "Wrangler" nameplate has existed. The last Jeep 4x4 to do so was still a CJ, or civilian Jeep, and the 304 cubic-inch engine came from American Motors Corporation. Incidentally, this generation of the Wrangler is also the first to be offered in a pickup variant. Cue the beard-stroking.  Now, frankly, it's not even remotely fair to compare the H3T's powertrain offerings to the decade-newer Gladiator's, but the Hummer actually boasts a few advantages over Jeep's modern pickup. While most of the Jeep's off-road specs give it an edge, the Gladiator doesn't come close to the H3T's 30.1-degree departure angle, for instance. And in more practical terms, the stubbier H3T has other maneuverability advantages. The Gladiator has 3" of wheelbase and 5" of overall length on the H3T, and a 22.4-foot turning radius to show for it. The Hummer's? Just 18.5'.

Jeep CEO promises Grand Cherokee Hellcat 'before the end of 2017' [UPDATE]

UPDATE: Video of Mike Manley confirming the Grand Cherokee SRT Hellcat has been added. In one of the worst kept secrets in the auto industry, Jeep has confirmed that the Grand Cherokee SRT Hellcat is coming. The news comes from Vvuzz, which has Jeep CEO Mike Manley on camera confirming the monstrous SUV. Manley confirmed that the Jeep, which we hope will offer the same 707-horsepower version of Chrysler's 6.2-liter, supercharged V8 as the Dodge Challenger and Charger, will arrive before the end of 2017. This, friends, is grand news. By the time the Grand Cherokee Hellcat arrives, it'll be faced with an array of high-performance challengers from BMW, Mercedes-Benz, Land Rover, and Porsche. But, if things stay the way they are with the competition and SRT engineers can bring the Hellcat engine's full output to bear on an all-wheel-drive platform, the Grand Cherokee will have a power advantage ranging from 130 to 157 hp. It's one thing to best the competition by a dozen horsepower, it's entirely different to outgun them by an entire Toyota Corolla. Expect much more on the Grand Cherokee SRT Hellcat in the coming months. Scroll on to see Manley confirm the news. This content is hosted by a third party.
