SUV lifts you up where you belong and leapfrogs traffic jams

So, you're at a dead stop, stuck in traffic, when it pulls up behind you. It appears to be a garden-variety Jeep Grand Cherokee. That is, until its undercarriage lifts the Jeep 9 feet into the air, and the whole rig straddles you and the cars ahead of you in a bid for open road. The car is called the Hum Rider, and no, you can't buy one at the Jeep store. It's a one-off publicity stunt intended to promote Verizon Telematic's Hum platform, which plugs into a car's OBD port and for $10 a month provides vehicle diagnostics, roadside assistance, location tracking, and speed and geo-fencing alerts. (Not sure if Hum tracks vertical leaps.) Verizon enlisted viral marketing agency Thinkmodo to promote the Hum, and this idea was head and shoulders above the rest. "We saw this one [and said], 'Wow, that is crazy,' said Jay Jaffin, Verizon's VP of marketing. "We loved the idea." Thinkmodo co-founder James Percelay told Mashable that they wanted to represent the upgrade Hum brings to cars. So the car goes up. Get it? Here's the star of this story: Hum Rider's designer, Scott Beverly, has done visual effects for Hollywood in The Dark Knight, Inception and Interstellar. He works for A2Zf, a Lancaster, Calif., design and engineering firm that keeps the world filled with Batmobiles, Red Bull Can Cars and beautifully designed VWs and Audis. A2Zf has also worked with NASA on X-planes and with Northrup on the B2 bomber, so compared to those projects, a car-straddling car is hardly a stretch. So what does it take to make a car do this? How about: Over 300 feet of hydraulic lines that operate everything - the lift mechanism, steering, braking and power to the drivetrain. A gas-powered Honda generator under the hood that powers hydraulic pumps pushing out 900 pounds of pressure. A lot of mechanical structure. Hum Rider weighs 8,500 pounds, almost double a standard Grand Cherokee. Heavy-duty truck tires to support all that weight. Four undercarriage cameras that allow the driver to see and clear what's beneath him. What did it cost? They're not saying. What would it be worth, the next time you're stuck in traffic? Priceless.

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.
