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.

Jaguar Land Rover proposes seats that scientifically massage your butt, for your health

Habitually sitting too long can degrade a person's health. Scientific research has proven that dormancy can increase the risk of obesity, diabetes, cardiovascular disease, deep-vein thrombosis, and metabolic syndrome, according to the Harvard Medical School. Although sitting can be avoided in many cases, such as using a standing desk at work, taking a seat is the only option when hopping in the car for a drive. Jaguar Land Rover (JLR) is hoping to address this negative aspect of cars with a new high-tech seat that the company says mimics the act of walking.  JLR calls the concept a shape-shifting, or morphable, seat system, and it is currently in a trial period with Jaguar Land Rover’s Body Interiors Research division. Using actuators built into the seat's foam, the seat will constantly be in motion with micro-adjustments that can be tuned to the needs of different people and body types. JLR believes it has created a system that recreates what is known as pelvic oscillation, a motion that can supposedly trick the brain into thinking the body is walking. In addition to helping to prevent internal health issues, JLR also notes that a sedentary lifestyle can degrade and shorten muscles in the legs, hips, and rear. If these muscles are worked on a regular basis, the chance and risk of injury and back issues could potentially be reduced. The new seats are just one of many car interior technologies JLR has explored. In the past, we've seen tech that tracks brainwaves and heart rates, creates augmented reality, helps prevent motion sickness, and helps stop the spread of germs. They've also taken the time to have an expert demonstrate the perfect seating position. Most of this stuff is experimental for now, but it's possible similar features could eventually trickle down to production cars, in time. See how the seat moves in the video below.

Jaguar Land Rover moves closer to building Slovakia plant

Jaguar Land Rover has announced its intention to build a new assembly plant in Slovakia. Though it has yet to make the final decision, the British automaker has signed a Letter of Intent with the Slovakian government. Its next step is to launch a feasibility study before committing. If the company does go ahead with plans, it wouldn't be the first automaker – or even the first European luxury automaker for that matter – to start producing in Slovakia. Nor would it be the first Jaguar Land Rover plant outside the UK, either. The Volkswagen Group, PSA Peugeot Citroen, and Kia all manufacture in the Central European country. VW's Bratislava plant in particular handles production of the Touareg, Audi Q7, and Porsche Cayenne. In the past few years, JLR has expanded its production capacity to new locations outside of the UK. It has a new factory in China, one under construction in Brazil, and has been manufacturing in India – home country of its parent company Tata – since 2011. It recently announced a manufacturing contract with Magna Steyr in Austria, and is investing in its facilities back home as well. Though yet to be finalized, the prospect of manufacturing in Slovakia has proven more favorable to JLR than other locations in Europe or in the United States or Mexico – all possibilities that the company says it looked into. It has yet to reveal just what it would produce there, saying only that "the plant would manufacture a range of aluminium Jaguar Land Rover vehicles," that the plant would be earmarked to come online in 2018 and eventually ramp up production to 300,000 vehicles. The prevailing wisdom would seem to indicate, however, that the site is being considered for the next-generation Land Rover Defender.
