Researchers test in-dash alerts telling drivers to stop or yield only when other cars are present.

By Douglas Newcomb Aug 12, 2014 2:17PM

Photo by Virginia Tech Transportation Institute Most motorists have seen drivers ignore a traffic sign and fail to stop or yield — and have probably been guilty of it themselves. But what would happen if those traffic signs didn’t exist and were replaced with electronic signs and warnings via an in-dash screen? And the warnings would only be shown if another vehicle was present at an intersection?


That’s what researchers at the Virginia Tech Transportation Institute want to find out in an experiment that relies on technology rather than metal signs. The research is designed to not only provide safe traffic flow, but also save time and fuel for drivers and cut down on emissions caused by cars stopping or slowing for no reason.


"The idea is there would be no physical stop or yield signs on the side of the road, but they would be inside the vehicle," Alexandria Noble, the Virginia Tech master's student leading the research project, told Phsy.org. And it’s more than just an idea since Noble and VTTI conducted real-world trials with vehicles and drivers to test the concept.

 

J.D. Power exec says carmakers need to go back to basics before adding features.

By Douglas Newcomb Aug 11, 2014 11:47AM

Honda AccordAnyone who has ever used a car’s voice recognition (VR) system knows how frustratingly inconsistent the technology can be.


While it works well in some vehicles, VR often struggles to perform even simple tasks such as calling a contact in the address book of a connected Bluetooth phone and finding a navigation destination. So it's no wonder when you ask for the nearest gas station, the system may reply (from a real-world example), “Find a Chinese restaurant.”


Kristin Kolodge, a director at J.D. Power and Associates, has some advice for automakers on how to fix the problem: Don’t add new VR features until you can first get the basic ones working well. Her position well-founded by J.D. Power’s annual Initial Quality Study, which at looks at problems and annoyances owners report on new cars in the first 90 days.

 

New sports car reportedly called Z35.

By AutoWeek Aug 11, 2014 11:34AM




The next-generation Nissan Z car will exhibit some wild changes from the current model. Things reportedly on the menu include a new name -- Z35 -- along with targa and T-top roof options and an engine from Mercedes.


Motoring.com.au talked to its sources at Nissan who said the Z car has traditionally been aimed at the U.S. and Japan, but that the next one will be a global sports car. It will target German contenders like the Porsche Boxster and Audi TT, and the convertible will have a retractable folding hard top, as opposed to today’s cloth top. The source also said the company is mulling both targa and T-top roofs.

 

Automaker has recalled more than 29 million cars a total of 65 times this year.

General Motors is recalling more than 461,000 cars in North America to fix ignition switches, seat belts and various problems, the automaker said on late Friday.

The latest recalls bring GM's yearly total to 65 recall campaigns and roughly 29.1 million cars.

On 2002-2004 Saturn Vue SUVs, the ignition key can be removed when the car is not switched off, which of course is a major problem. GM said it knew of at least two crashes and one injury related to the switch. Dealers will replace the switch and keys "if necessary"; they won't replace the faulty switches by default. A total of 202,115 cars in the U.S. are affected. 

Bubbles in the fuel line can cause a stall in very specific conditions on 2009-2014 Tiguan models.

Volkswagen is recalling 151,389 cars to fix fuel pumps that can stall the engine, according to filings with the National Highway Traffic Safety Administration.

The 2009-2014 Tiguan SUV can stall due to bubbles in the fuel line if winterized gasoline is used during warmer temperatures. The fuel tank pump can degrade from deposits left in the gasoline, may not be able to cope with higher vapor pressures and can starve the engine if it is restarted shortly after being shut off.

The problem typically occurs after an engine has been at operating temperature, is shut off and then restarted shortly afterward in what is known as an "engine hot soak." Volkswagen said it discovered the problem in February after noticing increasing warranty claims and later issued a technical service bulletin to dealers in June.  

Car’s 7-inch color LCD puts navigation, fuel economy and other info right at the driver's eyes in a crisp, clear fashion.

2015 Chrysler 200S.LCD instrument panels (IPs) are becoming common on more vehicles and are getting better at displaying useful information to the driver. I’ve found that Chrysler is on the forefront of this trend, especially in bringing the technology to lower-priced vehicles.


For example, the entry-level Dodge Dart has a basic LCD IP, while the Jeep Cherokee Trailhawk borrows aspects of the technology from its upscale mate, the Grand Cherokee. The new 2015 Chrysler 200C I recently tested has one of the best LCD IPs I’ve seen in any car, at any price.


It came in handy during a long haul from Los Angeles to Las Vegas and back last month by displaying everything from upcoming navigation maneuvers to the car’s fuel economy on the long drive across the desert in 100-degree-plus heat.

 

Partnership will standardize technology and communication between utilities and plug-in vehicles.

By Douglas Newcomb Aug 8, 2014 5:31AM

Chevy Spark EV. Photo by Chevy.Owners of a plug-in hybrid or electric vehicle ideally want to charge their cars when they can get the best rates, typically at off-peak times. Utilities prefer the same so they can better manage demands on the power grid. But there isn’t a standard among automakers and power companies to make it easy for drivers to know the best times.


That’s the idea behind a recent partnership between eight automakers and 15 power providers in the U.S. and Canada. The car and power companies will work with the nonprofit Electric Power Research Institute to develop and implement a standardized “smart grid” platform that will let plug-in vehicle drivers know the best times to charge to save money and also allow power companies to better handle demands on the grid.


Automakers participating in the partnership include BMW, Chrysler, Ford, General Motors, Honda, Mercedes-Benz, Mitsubishi and Toyota.

 

Touchtronic III transmission improves GT, Rapide S sedan.

By AutoWeek Aug 7, 2014 1:19PM




Aston Martin detailed changes to its Vanquish GT and Rapide S sedan on Wednesday. Big upgrades include the Touchtronic III eight-speed automatic transmission, which boosts economy and acceleration, a new engine management system and a more robust suspension for the Vanquish.


Output in the AM29 V12 engine grows to a peak of 568 hp at 6,650 rpm in the Vanquish, along with 465 lb-ft of torque at 5,500 rpm.


The updated transmission lowers the 0-60-mph time for the Vanquish from 4.1 seconds to a supercar-like 3.6 seconds, which confirms the car as the “quickest accelerating series production Aston Martin in the company’s history.”
