GM's MPG overstatement could affect 2 million vehicles

Late last week, GM admitted that three of its large SUVs fuel economy window stickers did not match their actual efficiency ratings, and so the vehicles couldn't be sold. The stickers on the 2016 Chevy Traverse, GMC Acadia, and Buick Enclave said their ratings were one to two miles per gallon better than they should have been. Officially, the number of affected vehicles sits at about 60,000. But Consumer Reports makes a good point: what's up with all of the previous model year SUVs that are basically the same vehicle? To wit: the 2016 model year vehicles are not substantially different than the 2015 or the 2014, or even going all the way back to 2007. On the EPA's fuel economy website, all of these older models will "have better stated fuel economy numbers than the new vehicles in GM's dealerships," Consumer Reports noted. CR's best point, and the one that makes the 60,000 number potentially grow to 2 million if all of the vehicles built on this platform are affected, is that "[i]t seems unlikely that the company would change the powertrain on these carryover models so late in their model cycles in a way that would cause a dramatic, negative impact on fuel economy." GM says that earlier model year SUVs are not affected and the EPA did not respond to CR's question about the potential for more discrepancies. We've seen automakers reverse course before, so if GM has to come out with a mea culpa soon, don't be surprised. GM is rushing corrected stickers to dealers so that the SUVs can be sold again, but a fix for the already-sold vehicles could be trickier to solve.

Jaguar I-Pace vs. Tesla Model 3 and other EVs: How they compare on paper

The 200-mile club of electric vehicles is really growing. The most recent member is the Jaguar I-Pace, the company's first pure EV. It promises luxury, performance, style, and most important, good range. Nearly as recent is the Hyundai Kona EV, and while it doesn't promise luxury or performance like the Jaguar (it's also smaller), it does pack impressive range. With the introduction of both of these electric cars, we thought we would see how they compare against each other, and the other two big names in high-capacity electric cars: the Chevy Bolt EV and the Tesla Model 3. This isn't intended to be a direct, apples-to-apples comparison, as the four are quite different. If anything, they break into two groups: bigger and more luxurious, and smaller and less expensive. Then again, the number of vehicles with this electric range is small and comparisons to EV's with less range wouldn't be too kind to the other guys. If you want to learn more about these EVs, and compare them with other cars, be sure to check out our Car Finder and comparison tools. Horsepower and torque There is one clear winner here, and that's the Jaguar I-Pace. It packs a whopping 394 horsepower and 512 pound-feet of torque. That comes through a pair of electric motors (one at the front, another at the rear) that provide the Jag with all-wheel drive, the only one of these vehicles to offer it (at the moment). Altogether, it allows the I-Pace to have the best 0-60 mph time of 4.5 seconds. At the other end of the spectrum is the Hyundai Kona EV. It's front-drive, like the Bolt EV, and has effectively the same amount of horsepower as the Chevy at 201 horsepower, but its 0-60-mph time is almost a second slower. And the low-range version of the Kona, excluded because it doesn't go more than 200 miles between charges, is slower still. The Tesla Model 3 is the only vehicle with rear-wheel drive, and with a 0-60 mph of 5.1 seconds for the Long Range model, it is still very quick. Range and energy use Frequently, the all-consuming question with electric cars is, "How far can I go on a charge?" And to go the farthest, you need the long-range Tesla Model 3. It can go 310 miles. It has the added advantage of being able to use the network of Tesla Supercharger stations, though they are pay-per-use with the Model 3. Even the lower capacity Model 3, with just 220 miles of range, can use these stations.

The U-2 spy plane needs high-performance cars to help land

Typically, aircraft deploy their landing gear from three main points. Most military aircraft, for example, deploy two gears at the back and one forward, like a tricycle. Some civilian aircraft flip the layout, with two in front and one in back - tail-draggers. The U-2 Dragon Lady is wildly different than any of these. With a 103-foot wingspan but a body that's just 63-feet long, the layout of the U-2 makes a traditional landing setup infeasible. Instead, the U-2 utilizes a pair of wheels, one up front and one in back. With such a bizarre layout, landings are so tough that since the U-2's earliest flights at Area 51, the US Air Force has used high-performance chase cars to guide the pilot down safely. The landing process isn't over there, though. As this video from Sploid shows, balancing out the aircraft to fit the detachable "pogos" – think training wheels for spy planes – is a comical procedure requiring a number of airman using their full body weight to even out the U-2. This video also recaps some of the great vehicles that have served as chase vehicles for this legendary spy plane. They include Chevrolet El Caminos, and the Fox-body Ford Mustangs so favored by the California Highway Patrol. For the last several years, the USAF has utilized products from General Motors, using fourth-generation Chevy Camaros, before switching over to the Pontiac GTO and most recently, the awesome Pontiac G8. It's fair to say that if you're a gearhead in the Air Force, this is the job you want. Check out the video, embedded up top.
