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.

Buy this instead of a Wrangler | 2017 Jeep Grand Cherokee Trailhawk Review

In our first encounter with the 2017 Jeep Grand Cherokee Trailhawk at Fiat Chrysler's Chelsea Proving Grounds, we saluted the new model's impressive on-road demeanor. In its off-road mode, however, we couldn't ignore the pre-production throttle calibration – it was super sharp and difficult to modulate with the precision needed to navigate obstacles. We were told then that Jeep's engineers were aware of the problem and were fixing it for production models. So we recently set off for Bundy Hill Off-Road Park in Jerome, Michigan, in a production-spec Grand Cherokee Trailhawk to check their work and get a better idea of the overall package. We can report that the Trailhawk's throttle has been fixed for production, landing it properly in Goldilocks territory. In the off-road Mud setting, the throttle is soft and easy to modulate. You can balance this rig with the gas pedal, reaching just past tip-in to steadily prod forward. But the gas pedal doesn't delay when you really need power. Move beyond the initial tip-in, and the engine responds quickly, which is a good thing, as a sluggish throttle is almost as dangerous off-road as one that's too sharp. Rock mode promises even more precise control over the throttle, although our lack of a spotter and a desire to avoid damaging the 700-mile-young Trailhawk kept us from hitting Bundy Hill's rockier sections. The wet, non-snowy weather meant we didn't properly test Snow or Sand mode. This test model was equipped with FCA's popular 3.6-liter V6, but like the rest of the Grand Cherokee range, more power is available from the 3.0-liter EcoDiesel V6 and the 5.7-liter Hemi V8. You don't need them – the 3.6-liter and eight-speed automatic are perfectly fine on the trails. Faced with an incline, the transmission holds its gear without complaint – you don't even need to switch into manual mode. Despite the 4,800-rpm torque peak, the V6's 260 pound-feet arrive early enough that you don't need to strong-arm the throttle. So that's resolution for the pre-production issue. But our time at Bundy Hill exposed a different and ultimately much easier to fix problem for the production model. Late fall in Michigan is not always a good time to go off-road – sub-40-degree temperatures and a steady, depressing drizzle can turn a relatively simple trail into a slippery mess of wet clay. Conditions like these can easily overwhelm an on-road tire like the Goodyear All-Terrain Adventures the Trailhawk uses.

FCA's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.
