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.

2018 Jeep Wrangler Buying Guide | Answers to your SUV questions

There are few truly one-of-a-kind vehicles, but the Jeep Wrangler remains one of them. Available in traditional two-door form, or as the four-door Unlimited model, this proudly square-shaped SUV traces its origins back to the battlefields of World War II. While its shape seemingly hasn't changed much over the years, the 2018 Wrangler has been completely redesigned inside and out. A 3.6-liter Pentastar V6 and all-wheel drive are standard across the extensive Wrangler lineup, including rock-crawling versions like the highly regarded Rubicon model. While it doesn't have any direct rivals, some buyers might prefer an SUV with more refined ride and handling characteristics. The Wrangler's solid front and rear axles' primary purpose is off-road adventure, not on-road comfort, no matter how much it's been improved over its predecessor. Here you'll find all the information needed to make an educated buying decision if you're considering a 2018 Jeep Wrangler including safety and reliability ratings, engine specs, horsepower, fuel economy ratings and pricing. We'll also summarize what Autoblog's professional auto reviewers think of the Wrangler. Is the 2018 Jeep Wrangler Safe? The National Highway Traffic Safety Administration has not given the 2018 Jeep Wrangler an overall safety rating. However, the 2018 Wrangler is listed as scoring three out of five stars in frontal crash tests and rollover resistance. The Insurance Institute for Highway Safety, which provides ratings for new vehicles based on its own comprehensive crash tests, did not give the 2017 model year (previous generation) Wrangler, the last one fully-tested, a recommended rating. The 2017 Wrangler scored a "marginal" rating for driver side safety in the small overlap frontal crash test (a passenger side rating was not recorded). Side impact performance came in at a "poor" rating, as did overall headlight performance. One bright spot in an otherwise dismal safety score was the Wrangler's "good" rating in the moderate overlap front crash test. Ratings may differ for Wrangler models from other model years, so be sure to visit the https://www.nhtsa.gov/ NHTSA and http://www.iihs.org/iihs/ratingsIIHS websites to review ratings on the specific vehicle you're researching. At the time of this writing, the 2018 Wrangler is subject to one ongoing recall involving 106 vehicles.

Watch a Cayenne Turbo S, Range Rover SVR, and Cherokee SRT drag race

We live in a weird world where high-performance SUVs could win a 60-mile-per-hour sprint against sports cars from just a few years ago. Here, Top Gear sets up a three-way drag race against the Porsche Cayenne Turbo S, Land Rover Range Rover Sport SVR, and Jeep Grand Cherokee SRT, and the results show just how quickly these high-riding models can cross the quarter mile. The Cherokee SRT is the patriotic choice among the three, but it's down on power in this fight. Meanwhile, the Range Rover's menacing growl sounds the best, and the Cayenne Turbo S has the most horsepower. You'll have to watch the video to see which SUV will win this battle. Related Video:
