Audi follows in parent company Volkswagen's footsteps by bringing a car to the U.S. with a TDI diesel engine. Using the same turbocharged 2-liter diesel engine as the VW Jetta, the A3 TDI offers the same stellar fuel economy as its lesser German cousin, and it has better cabin tech, including a good iPod connection and Bluetooth phone system. However, Audi lets the A3 TDI simmer with an older version of its navigation system that's not quite on par with its latest technology.
A teenager talking or texting on his or her cell phone while driving is a fear for parents and other drivers alike. According to a new study by the Pew Research Center's Internet & American Life Project, 25 percent of U.S. teens aged 16 to 17 who have cell phones admitted to texting while driving, and twice as many say they have been in the car with someone that has.
A new cell phone application, by Cell Cease, aims to limit this distraction. Cell Cease, which works exclusively on Windows phones, blocks calls and texts while a vehicle … Read more
We suffered through bank bailouts, car manufacturer bankruptcies, mortgage defaults, and high unemployment, but there was a bright side to the past few years: traffic congestion has been down below its peak 2007 levels, according to traffic chronicler Inrix's latest National Traffic Scorecard.
Inrix, which uses 1.6 million vehicles to collect traffic flow data, notes that traffic congestion during commute times showed a significant reduction during the recession. But as a sign that the economy is turning around, traffic is starting to get worse.
Overall congestion was reduced by one third in 2009 from 2007 levels, but Los … Read more
The S-class is a tech-lover's dream, loaded with seats that massage, radar that keeps set distances from other cars, mirrors that warn about cars to either side, and a speedometer that turns into a night vision camera. We were in seventh heaven riding around on its plush seats, listening to music from an iPod over its sweet-sounding Harman Kardan audio system.
And while previous S-classes left us with a little green guilt, or at least range anxiety, as the engine gulped down the gas, the S400 Hybrid has a more reasonable appetite. It is far from Prius territory, but … Read more
Good old Wi-Fi could be the fix to an impending explosion of data on wireless networks.
Nearly three years after Apple introduced the game-changing iPhone, wireless operators around the globe are feeling the effects of the wireless data tsunami that is well under way. Even networks that don't support the iPhone are feeling the pinch as a generation of new wireless devices offering bandwidth-hungry Web applications are hitting networks.
The result, as many iPhone users in New York City and San Francisco will tell you, is a network that drops calls and offers wireless Net surfing at the speed of a turtle.… Read more
We haven't seen a desirable Buick in so many years that our expectations were very low when the LaCrosse arrived in our garage. Yet this car turned out to be one of the better luxury sedans we've driven, especially at its price. The cabin tech suite includes a navigation system with excellent traffic avoidance features and a Harman Kardon audio system with exceptional audio quality.
The soft suspension rides over bumps well, while the direct injection 3.6-liter V-6 delivers ample, efficient power. The LaCrosse is truly a car that will make people give Buick another look.
Update: 8:30 a.m. 2-10-10: To include chart of ComScore numbers.
On the same day that Warner Music Group reported lackluster earnings, the third largest music recording company appears to have at least one thing to celebrate: dramatic new interest in the label's YouTube videos.
From December to January, the number of unique visitors to Warner's YouTube's clips appears to have more than doubled from 23.3 million to 47.5 million, according to ComScore. What that means is Warner's music videos are now the most popular on the Web. In one month, Warner has … Read more
Researchers from Spain, Switzerland, and the U.S. used ultrasound to measure the carotid artery wall thickness of 1,483 people living near freeways in the Los Angeles area. They took measurements once every six months for three years and correlated the numbers with estimates of outdoor particulate levels at each participant's home.
The artery wall thickness among those living within 100 meters (328 feet) … Read more
If wireless operators thought they'd faced a deluge of data traffic from the iPhone, they haven't seen anything yet, according to a survey from network equipment giant Cisco Systems.
Cisco, which makes the routers and switches that shuttle IP traffic around the Internet, has been using its Visual Networking Index to forecast Internet usage. On Tuesday, the company announced results from its Global Mobile Data Forecast for 2009 to 2014.
By 2014, researchers predict, mobile data traffic throughout the world will reach 3.6 exabytes per month, or an annual run rate of 40 exabytes. This is a … Read more
It's a rare SUV that comes with a manual transmission. It's an even rarer SUV that can justify it. The Porsche Cayenne GTS's handling makes a manual transmission a preferred option. Unfortunately, just not the particular manual used in the GTS. This car's handling finesse makes you want to give it a quick downshift before a corner, to get the most out of its 405 horsepower engine on the way out, but shifter's long throw adds to that gear change time significantly.
That criticism aside, this new Cayenne sports some new cabin tech, a suite … Read more
