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.

NHTSA closes investigation into Jeep Liberty fires

The investigation that the National Highway Traffic Safety Administration opened into the Jeep Liberty in October 2013 has been closed. NHTSA received two (!) complaints about fires starting in the driver's door, thought to be caused by the master power window switch. The initial estimate was that 80,000 Libertys could be roped into a possible recall, but according to a report in the Detroit News the agency examined records for 425,000 Chrysler products that used the same window switch, including the Dodge Nitro and Chrysler Town & Country minivan.
After canvassing 265 warranty claims related to the master switches, NHTSA concluded that the rate of fires compared to the "large population of vehicles" was rather low, and that there was no trend pattern behind the few issues it did find. Perhaps with that, and the closure of the trailer hitch investigation, the Liberty can finally rest in peace.

How to tune a car right: Part 3, tuning Mopar with OST Dyno

Not long ago, I wrote a story about a pony car tuned with a supercharger. The blower install had been done properly. Then the car's owner bolted on a set of great looking wheels wrapped in good looking but inexpensive rubber. On my first test drive, I couldn't get any of that supercharged sweetness to the ground. It was the perfect ride for parking in a Burger King parking lot on a Friday night. I tooled around on a Sunday drive, shaking my head that someone had spent five figures to get more power the right way, with a clean install, then wiped out the gains so thoroughly that the stock engine would likely have overwhelmed the tires. This got me thinking about the ways people ruin their quest for horsepower, either on the front end by not insisting on a clean install and paying the money for it, or on the back end with supplemental purchases like cheap tires or cheap gas. So I called three tuners, one focused on GM, one on Mopar, one on Ford, to find out what people should know about how to get the best power for their goals, and how to make sure they are able to use all that power. The first interview in this three-part series was with Blake Leonard at Top Speed Cincy in Cincinnati, Ohio, the second with Brandon Alsept at BA Motorsports in Milford, Ohio. This third and last interview is with Micah Doban at OST Dyno in Slippery Rock, Pennsylvania, a family business with more than 40 years of Mopar expertise specializing in Gen III Hemis, but tuning everything from land-speed cars and drag racers to Jeeps The interview has been edited for clarity and concision. Do people who come to OST generally know what they want? Probably 80% of the people who come in simply want more power with no particular ET goal [ET is a kind of bracket handicapped drag racing – ed.]. WhatÂ’s the best way to start a Mopar tune? The first thing is what people often skip, and that's to find a tuner or a shop. People will throw parts on their cars that the Internet said to, then go to a tuner who does things a different way, and [the tuner is] like ‘No we don't like to use these injectors, we don't like these parts.Â’ You have to find someone familiar with the parts that are on your car or that you're planning to put on your car. So having a goal and then finding a tuner who can help you with that goal is proper way to start. Exactly. And a lot of tuners have their own formula – and when I say tuner I mean someone that also does work to the cars.
