2017 Jeep Grand Cherokee Trailhawk Quick Spin

Jeep won't come out and say it, but the 2017 Grand Cherokee Trailhawk exists to bloody the nose of the Toyota 4Runner TRD Pro. America's off-road brand hasn't built a wheeling-specific version of its Grand Cherokee flagship in years, and the last GC Trailhawk was mostly stickers and tires. It was time for a true trail-spec Grand Cherokee again. We took a quick spin (two of them, actually) in the latest Trailhawk model, which joins Renegades and Cherokees with the same badge and off-road bent for 2017. Our time was limited, and so were our initial findings. After driving on and off pavement at Fiat Chrysler's proving grounds in Chelsea, Michigan, we can tell you that on the road, this Grand Cherokee has the same refined driving dynamics as any other. As for off-roading, the capability is still somewhat of an open question. Driving Notes The suspension and off-road system tuning are what really set the Trailhawk apart from other Grand Cherokees. Jeep tweaked the four-corner Quadra-Lift air suspension to improve articulation and suspension travel, while retaining the 10.8 inches of ground clearance of lesser Quadra-Lift Grand Cherokees. Paired with the standard Quadra-Drive II four-wheel-drive system, rear electronic limited-slip diff, and 20-inch Goodyear Adventure off-road tires, the Trailhawk is not short on capability (at least on paper). Unfortunately, paper is almost where this stops. The Trailhawks we drove were pre-production models with unfinished software calibrations. The throttle on the 3.6-liter V6 Trailhawk we took on the off-road course was super touchy and hard to modulate, regardless of which Selec-Terrain off-road mode was selected. Without a reliable throttle, we were bounding over obstacles instead of negotiating them patiently. This was back in June, and Jeep's PR reps assured us at the time that the engineers knew about the oversensitive throttle and have since confirmed that the issue has been fixed for production models, which are rolling off the line in Detroit now. We're planning to get into one of those vehicles as soon as one becomes available for a full review. Like the standard model, the Trailhawk's air suspension offers more comfort than the double-wishbone front and four-link rear suspension on the 4Runner.

Supplier says Jeep Cherokee hack only affects FCA cars

Harman doesn't think that drivers need to worry about any further hacks of its products. The company supplies FCA's Uconnect infotainment system where a software vulnerability is responsible for a 1.4-million vehicle recall. "This experimental hack is unique to Chrysler," Harman CEO Dinesh Paliwal said to Automotive News. "This does not exist, to our assessment, in any other vehicle." The reason that the company wouldn't be involved is that automakers aren't simply plugging in the existing infotainment systems into new vehicles. According to Paliwal, Harman supplies the unit, but FCA and other automakers are able to make additional modifications for their vehicles. The National Highway Traffic Safety Administration has also recently taken up the question of broader software vulnerabilities in Harman's products. On July 29, the agency began investigating the company to check for similarities between Uconnect and the infotainment systems supplied to other automakers. The Jeep hack became national news when two researchers were remotely able to take control of a Cherokee. The vulnerability in the cellular connection even gave control over the brakes. "Once people get in the car and get into the CAN bus, then you can start to mimic and mess up many, many things in the car," Paliwal said to Automotive News. Politicians immediately responded with legislation to create federal standards in hopes of protecting drivers better. NHTSA also opened an investigation to make sure the automaker's software update actually solved the problem. Related Video:

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.
