Roller coaster or racecar, which pulls more Gs?

Looking for a thrill? You're not the only one. You'll find kindred spirits at airfields going up for a skydive, atop bridges and towers with bungees attached to their feet and standing in line for roller coasters at the local amusement park. But you'll also find them in the paddock at the racing circuit.
So what's the commonality? G-force. It's like gravity, only in each of these cases, it's experienced by human invention. But which activity subjects your body to the greatest amount of g-force? That's what Nissan set to find out.
Before putting them back in the cockpit, Nismo sent out two of its young hot-shoes - Jann Mardenborough and Mark Shulzhitskiy - to an amusement park in the UK with a camera and a g-force meter to find out if any of the coasters could produce as much lateral gravitational force as an LMP2 racing car. See what they found in the pair of videos, below.

Full 2015 Chevy City Express details revealed

If you're thinking, "hey, that looks familiar..." you aren't alone. We've already seen photos of the 2015 Chevrolet City Express van. And before that, we've already learned everything there is to know about the Nissan NV200 upon which its quite obviously based. Now, though, the City Express is holding its official coming out party at the Chicago Auto Show, and we finally have the official details about what'll hopefully make this van attractive to work-minded buyers.
To no one's surprise, the City Express doesn't offer any mechanical differentiation from its Nissan equivalent. Power comes from a 2.0-liter inline four-cylinder engine rated at 131 horsepower and 139 pound-feet of torque, mated exclusively to a continuously variable transmission. Of course, the purpose of the City Express is less about what's under its hood and more about what it can haul in its capacious cargo area. Chevrolet says the front passenger seat can fold flat to create a work space or accommodate longer objects in the cargo bay, there's a center console designed specifically for maximum storage capability and both sides of the van have sliding doors. In addition, there are a plethora of integrated cargo mounts, floor-mounted D-rings and roof rack mounts throughout the vehicle.
Visually, Nissan's NV200 has never exactly been a handsome thing to begin with, and this City Express doesn't really tweak it for the better - to our eyes, it might even be less attractive. Even the design of the 15-inch wheel covers have been left alone, though the Chevy shown here appears to wear chrome-finished units.

Should heavy-duty pickup trucks have window stickers with fuel mileage estimates?

If you were to stroll into your nearest Chevrolet, Ford, GMC, Nissan, or Ram dealership, you'd find a bunch of pickup trucks. Most of those would have proper window stickers labeled with things like base prices, options prices, location of manufacture, and, crucially, fuel economy estimates. But you'd also run across a number of heavy-duty trucks with no such fuel mileage data from the Environmental Protection Agency. The EPA doesn't require automakers to publish the valuable miles-per-gallon measurement for vehicles with gross weight ratings that exceed 8,500 pounds. That makes it difficult for consumers to compare behemoths powered by turbocharged diesel engines – between one another, and between smaller, gasoline-fueled trucks. Consumer Reports doesn't think it should be this way, and it's spearheading an effort (PDF link) to get the government to require manufacturers to publish fuel economy estimates. In its own testing, CR found that heavy-duty pickups powered by Ford's Power Stroke, GM's Duramax, and FCA's Cummins diesel engines (which doesn't include the Ram's EcoDiesel) get worse fuel mileage than their lighter-duty gas-powered siblings. We're not so sure HD-truck buyers are unaware of this fact – big diesels don't really come into their own until big loads are placed in their beds or attached to their trailer hitches. Under heavy workloads, the diesel trucks will almost certainly return greater efficiency than a similar gas-powered truck. What's more, HD trucks with lumbering diesels in general make the driver feel more confident while towing due to greater torque at low engine RPM than gas trucks. They also offer greater max-weight limits. Still, we agree EPA fuel mileage estimates should be offered for heavy-duty pickups. And we think the comparisons provided by Consumer Reports might be interesting to potential buyers. Click here to see the results of CR's tests, and let us know what you think using the poll below.
