A3 E-tron previews Audi electric car

Ever since 2009, Audi has been showing off enticing electric cars under the E-tron name, its brand for any electrified power train. I finally got to drive one during a green industry conference in San Francisco, but it was a far cry from the original sporty-looking E-tron concept. However, the A3 E-tron looks a lot more like a car that Audi would put into production.… Read more

What's so great about direct injection? (ABCs of Car Tech)

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

What the heck is torque steer? (ABCs of Car Tech)

Torque steer is a phenomenon that mostly affects front-wheel-drive cars where heavy acceleration causes the vehicle to veer to the left or right.

Take a front-wheel-drive car to a wide, open space where you can test acceleration from about 0 to 15 mph without hitting something or someone (perhaps a big empty parking lot). Take both hands off of the steering wheel and give the accelerator a brief but firm squeeze. What did you notice? For most FWD cars, you likely saw the steering wheel twisting to one side and the vehicle lurching to either the left or to the … Read more

BMW and GM part ways on fuel cell research

Heightening speculation that BMW and Toyota are about to announce an expanded partnership involving fuel cell technology, the German automaker confirmed today that it is no longer talking with General Motors about a similar research arrangement, reported a Bloomberg article.

On Friday, BMW and Toyota will hold a press conference announcing the details of a closer working relationship. Last December the two companies penned an agreement that gave Toyota access to BMW's small diesel engines to sell in its European line up of vehicles, and in return, Toyota would help BMW play catch up in the hybrid market by … Read more

BMW and Toyota co-developing fuel cells

Toyota and BMW are expected to announce this week a closer working relationship that expands upon the one they struck last year.

In December 2011, the two companies announced that they'll be collaborating on fuel-efficient and alternative power-train vehicles, with BMW supplying small diesels to Toyota to power its cars sold in Europe. In return, the Japanese car manufacturer would help BMW with the development of next-generation lithium ion batteries.

However, the working relationship won't end there. BMW and Toyota also plan to pool resources on fuel cell technology, according to unconfirmed reports first published in the Nikkei … Read more

How Bill Ford turned an automaker into a tech company

My perception of Ford Motor is probably similar to most people's. The Mustang was the hallmark car in the '70s. The company suffered the same malaise as other automakers in the '80s, while the '90s saw bigger and bigger SUVs. And, of course, there was the ever-present F-150, either seen as beat-up work truck or shiny suburban boat hauler.

Somewhere along the way Ford's trajectory changed, though, to the point where it is now leading the technology charge in vehicles.

I found out how it all changed from the horse's mouth, as it were, at a speaking … Read more

Ford's 999cc EcoBoost engine wins top honors at Engine Awards

Click through for the full photo gallery and more details.

This year's International Engine of the Year Awards saw many repeats from 2011, but stealing the show was a new sub-1-liter engine from Ford. Using direct injection and a turbocharger, this 999cc engine manages to generate 123 horsepower, enough for most subcompact and compact cars. And in European test cycles, the engine manages well over 50 mpg.

Despite the economy of Ford's engine, the Green Engine Award went to GM for the range extended electric power train in the Chevy Volt and Opel Ampera.

Here are the various … Read more

U.K.-market Audi BiTDI engine adds extra turbo, oddly placed speaker

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

Ford's smallest engine finds home under hood of Indian EcoSport

Last year, when Ford announced its smallest EcoBoost engine yet, we fully expected the new mill to find its way under the hood of a Ford Fiesta. Turns out that we were only partially correct.

Today, Ford announced that it would be unveiling the all-new Ford EcoSport at the New Delhi Auto Expo. This small crossover--which looks like a ruggedized, upright version of the Fiesta hatchback--will be powered by the smallest of the EcoBoost family, the turbocharged and direct-injected, 1.0-liter, three-cylinder engine.

Ford claims that with an output of about 118 converted horsepower (120 PS), this mighty mite of … Read more
