Unclear Wording In SAE J-1634 Standard Doesn't Help
The EPA's test to certify the range of electric vehicles and plug-ins is a convoluted mess in many cases that often doesn't accurately evaluate driving range. Green Car Reports takes a look at the problem in a recent deep dive and finds a relatively simple solution.
The Viper is used to being the most powerful car in the Dodge and SRT stables, but the arrival of the 2015 Dodge Challenger SRT Hellcat means that's no longer the case. The serpentine supercar is, however, reportedly getting a small boost in output for 2015, amounting to all of five horsepower.
Thanks to the Society of Automotive Engineers (SAE), when car shoppers look at horsepower and torque figures on vehicles, they know that all the automakers are calculating them the same way. However, that isn't the case when it comes to truck buyers and max towing capacity ratings because each company figures the value differently. That practice finally changes with the SAE's standardized J2807 system, though, and Ram Truck is the first one to apply the new test procedure to its entire light- an
We often hear how an electric vehicle powertrain architecture allows vehicle designers much more freedom than a traditional ICE powertrain does. With differently shaped battery modules and small electric motors, there are lots of way to put the pieces together. With today's plug-in hybrid technology, engineers still need to put a decent-sized ICE somewhere, but new technology from Toyota could free up the gas-electric vehicle designers of the future.
At the SAE World Congress in Detroit last week, FEV showed off what it calls an "innovative" new plug-in hybrid transmission. The reason for that moniker is that the system does away with the need for a torque converter while offering two speeds, which makes it particularly good during launch. If the electric motor is used to get going, once up to speed, the engine kicks in for "efficient highway driving" and the system is capable of both electronic boost as well as capturing regenerative brakin
Things are running a little bit behind on Hyundai's hydrogen-powered Tucson Fuel Cell CUV program in the US. The last time we checked in with the South Korean automaker's H2 project, we heard that the first deliveries were supposed to happen by the end of March. Speaking with Hyundai's Kevin Lee at the Hyundai booth at the SAE World Congress this week, we learned that deliveries are now going to happen closer to a month from now.
Car buyers have a responsibility to be well-informed consumers. That's not always a very simple task, but some guidelines are self-evident. If you live in a very snowy climate, you generally know a Ford Mustang or Chevrolet Camaro might not be as viable a vehicle choice as an all-wheel drive Explorer or Traverse, for example. If you want a fuel-efficient car, it's generally a good idea to know the difference between a diesel and a hybrid. But what if it's kind of tough to be an informed consumer
Think of it as a BMW-General Motors combo for the Combo. The two automakers have worked together to ensure that the BMW i3 and the Chevrolet Spark Electric will be the first two US vehicles to be compatible with the recently developed Society of Automotive Engineers' (SAE) so-called fast-charging "Combo" standard
Sometimes, a little suggestion goes a long, long way. Speaking at the SAE World Congress in Detroit today, Bob Lutz took a proposal from the conference organizers to frame his speech around the idea that he was king of the auto industry for a week and ran with it. He said he'd need to rule over the entire US to get his ideas enacted, oh, and be an all-encompassing emperor instead of a mere king. In other words, Maximum Bob remains as big as ever, attacking the "religion" of climate change, point
BMW has joined Daimler and, potentially, Audi in quitting an automotive industry research program studying a proposed new air conditioning refrigerant, the simply named HFO-1234yf. BMW disagrees with the test methods being used. "We do not want to say the test results are wrong, but we are not convinced the methods applied are sufficient to achieve a definitive conclusion that guarantees our high safety standards," a spokesman for BMW told Reuters.
True to their name, the number of CHAdeMO-standard quick-charging stations for electric vehicles is growing real fast. The number of global stations that use Japan's quick-charging CHAdeMO standard has doubled in the past year to more than 2,000 units – and will more than double this year, as more public and private entities look to give EV owners the option of recharging their cars in a matter of minutes.
Among the best reasons to buy a new car are the safety improvements that have been made across the industry over the past decade. Yet safer cars for drivers and passengers haven't meant an improvement for first responders. On the contrary, the added complexity and new technologies employed in modern vehicles routinely frustrate firefighters attempting to save occupants involved in a crash.
We've seen this sort of thing before – a group agrees to adhere to a common standard at some determined date, then when the date arrives, one or more parties in the group figures out how to 'adhere' in a completely new way. When the Society of Automotive Engineers (SAE) laid out its J2807 tow-rating guidelines a few years ago with input from domestic and Japanese truck makers and tow suppliers, the standardized testing regime was applauded as a way to provide reliable comparisons between m
