Jaguar tests autonomous vehicle technology with 100-car fleet

Jaguar Land Rover is exploring how to take autonomous vehicle technology off the paved path. But the company has plans for technology on tarmac, too. The company announced that the Jaguar division will have a fleet of 100 cars testing autonomous technologies on public roads. The testing process will cover a period of four years and begin with vehicle-to-vehicle and vehicle-to-infrastructure communication systems, along with a stereo camera system and autonomous vehicle software. These systems will work together to provide a variety of features that could make their way into future Jaguars and Land Rovers. The first feature in development is called "Roadwork Assist." The system relies on the stereo camera to create a 3D image the car's software can analyze. The software can identify road cones and other barriers associated with construction sites. The car will then alert the driver about entering the construction zone and provide some steering assistance to keep the car centered in its lane. Tony Harper, Jaguar's head of research, said that this system can reduce stress on the driver, and the technology could eventually be used to allow the car to pilot itself through construction zones. Another of Jaguar's proposed features is "Safe Pullaway," which also relies on cameras and software. The Safe Pullaway feature is designed to prevent close-proximity collisions in traffic jams and even in the garage. To do this, the car watches the area immediately ahead of it for obstacles. If the car detects something nearby while the driver adds throttle or shifts into gear, it will apply the brakes to prevent driving into the object. The final project on Jaguar's plate is its "Over the Horizon Warning" system. This will be one of the first features to rely on Jaguar's vehicle-to-vehicle communication technology. The idea is that connected cars in constant communication will give drivers additional warning of upcoming hazards, such as out-of-sight animals and slowed or stopped cars. In Jaguar's example of a stopped car, the stationary vehicle would send a signal alerting approaching cars of the situation. In turn, the approaching vehicles would trigger audible and visual warnings to drivers about the hidden car. Jaguar says that the system could also be applied to emergency vehicles. Emergency vehicles would broadcast a signal to alert drivers well before the lights and sirens get their attention. This would give emergency vehicles a faster, safer path through traffic.

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.

2020 Land Rover Defender vs. 2020 Jeep Wrangler: How they compare on paper

For ages, the Jeep Wrangler has had the serious off-road SUV market in America all to itself, especially when it comes to two-door variants. But competition is coming, and the first on its way is the 2020 Land Rover Defender, which was just revealed at the Frankfurt Motor Show. Each packages retro looks and impressive off-road capability, but does one have an advantage? We decided to take a look into each SUV's specifications and compare them on their engines, drivetrains, interior space and towing among other things, to see how they stack up. Since both SUVs are offered in two-door and four-door versions, we've made sure to feature both versions. You can find all the vital stats in the chart below, followed by more in-depth analysis. Engines and drivetrains The Land Rover is the clear high-performance option of these two SUVs. Its base turbocharged 2.0-liter four-cylinder, offered only in the four-door Defender 110, is more powerful than either of the gas engines offered on the Jeep Wrangler. The Wrangler's four-cylinder matches it on torque, at least. The optional turbocharged 3.0-liter inline-six in the Defender makes over 100 more horsepower and pound-feet of torque than either Jeep gas engine. But if you're looking for diesel propulsion, along with its associated torque and fuel economy, the Wrangler will be your only option. Final specs haven't been released, but in the Ram 1500, the same engine makes 260 horsepower and 480 pound-feet of torque. Fuel economy hasn't been announced for the Land Rover or the diesel Wrangler. But if fuel economy is a concern, the four-cylinder Wrangler is the most frugal of the SUVs we have numbers on. As for transmissions, the Wrangler is your only choice if you have to have a manual. It's available on both the two-door and four-door models, but only with the V6 engine. If you don't mind an automatic transmission, both SUVs come with variations on the ZF eight-speed auto. Getting the power to the wheels is another area where these two SUVs diverge. The Jeep is very traditional with a standard selectable four-wheel-drive system with two-wheel drive, and low- and high-range four-wheel drive modes. On the Sahara, there's an available full-time four-wheel drive mode, but the other modes are still available. On the Land Rover, you get full-time four-wheel drive, the same kind used on the Land Rover Range Rover.
