When shopping for a new car, the old questions remain relevant. Does it have enough seats for my family and friends? Are the seats comfortable? Will it suit all the uses for which I need it? Does it get good fuel economy? Is it safe?

However, there are many new tech features available that can make your drives more comfortable, keep you out of traffic jams, and prevent accidents. In addition, there are different drivetrain options that can save you a lot of money, depending on your lifestyle.

In this guide, we will let you know what features you can … Read more

You may have read or heard one of your favorite Car Tech editors talking about gasoline direct injection and how it's one of the "big technologies" that's helping to keep the almost 200 year-old internal combustion engine alive well into the 21st century. In this week's issue of the ABCs of Car Tech, I'm going to explain just what the heck gasoline direct injection is and why you should care if it's in your next car's engine or not.

How did fuel injection work before direct injection?The modern gasoline internal combustion … Read more

Pop quiz, tough guy: How do you make VW/Audi's direct-injected, turbodiesel engines better? If you answered "add another turbo," then congratulations. You're now ready to work for Audi's R&D department!

Okay, so I'm sure that Audi's engineers are a bit more qualified than that, but "adding another turbo" is exactly what they did with the advent of the new BiTDI 3.0 V-6 engine. The new engine, which will find its way under the hood of diesel-powered A6 and A7 Sportback models in the U.K. market, features … Read more

Short of employing a full hybrid system, automakers are finding many ways to improve fuel economy in current, gas-engine cars. Engineers are looking at every part of the drive cycle to determine where savings can be made.

Some of the technologies being employed are old, such as turbochargers and continuously variable transmissions, but they are being refined to take advantage of new materials and computing power.

There have also been some newer innovations that cut fuel use, such as the use of idle stop and dual-clutch transmissions.

A number of factors are helping push these developments. Consumers are trying to cope with increasing gas prices, and governments are pushing for reduced carbon dioxide emissions, which relate directly to fuel economy.

Check out these 11 technologies that reduce fuel consumption. … Read more

A hacker accessed personal details of Nokia developers in an attack on the Nokia Developer site last week, the phone manufacturer has admitted.

The intrusion resulted in the apparent attacker, pr0tect0r AKA mrNRG, redirecting visitors to the Nokia Developer Community forum to a page berating Nokia for its server security. Yesterday, Nokia told forum members that it had originally believed "only a small number" of their records had been accessed, but it had since revised that analysis.

"Further investigation has identified that the number is significantly larger," Nokia said in an e-mail sent to developers, apologizing … Read more

The average Web-based application is hit by a cyberattack once every two minutes, says a report out today by security firm Imperva.

Detailing its findings in its "Web Application Attack Report" (PDF) for July, Imperva found that Web applications are attacked around 27 times per hour. Monitoring the Internet from December 2010 through May 2011, the security firm uncovered and categorized more than 10 million individual attacks targeting both business and government sites.

Automated cyberattacks accounted for a huge number of attempted breaches. The report discovered that attack traffic was characterized by quick spikes of high volumes followed … Read more

Sony's turn as the whipping boy for Internet hackers continued over the weekend. Two hackers posted a list of e-mails they say they took from the Sony Pictures France Web site.

The two hackers who claim responsibility are a Lebanese student who goes by the handle Idahc, and a French friend of his who goes by Auth3ntiq. The two say they copied 177,172 e-mails from the entertainment company's site, but posted only 70 of them on the code-sharing site Pastebin. They say they will not be posting all of the e-mails they found.

Ford's been taking advantage of its EcoBoost forced-induction technology to downsize engines across its line. V-8s give way to turbocharged V-6s. V-6s give way to turbo four-bangers. Continuing the trend, Ford has just announced the smallest engine it's ever built: a 1.0-liter EcoBoost three-cylinder engine.

Besides the obvious fuel savings from its lower displacement, Ford's new tiny terror packs in all sorts of economy-boosting technologies. For example, Ford's split cooling system helps the cylinder block to warm faster which helps to save fuel during the least efficient warm-up phase, especially in cold weather. The three-cylinder'… Read more
