Adam Carolla is world's the least helpful test drive co-pilot

If you were going to test drive a new car, who would you want to take with you? Your spouse? A friend? Maybe an automotive journalist? Well take it from us: there's one of us riding shotgun just about every time we go to drive anything, and we're not all we're cracked up to be.
How about a celebrity comedian? Well, that largely depends on which comedian we're talking about here. Some - say, Jerry Seinfeld or Jay Leno, for example - might be more helpful than others, being more or less schooled in the finer points of the modern automobile. Adam Carolla might seem like he belongs on that list too, but in this latest video for a friends at Edmunds.com, the one-time host of The Car Show on Speed TV seems bent on being as comedically intrusive as possible. Which may be funny, but helpful? Not so much. See what we mean in the video below, and the next time you go to test drive a new car, you just might find the world's most popular podcast host climbing in with you.

Audi starts production of new TT in Hungary

Audi sure made waves when it rolled out the original TT in the late 1990s, putting fashion forward with a stylish coupe that neatly summed up the design direction the company was headed in. But that was a decade and a half ago, and the TT has moved on considerably since then.
The German automaker has since revealed its third-generation TT, replacing the original twice over with ever-more performance-focused but no less stylish successors along the way. But it wasn't until last week that the first new MkIII TT rolled off the assembly line.
That took place, of course, in Gyor at Audi Hungaria Motor Kft. It's the same assembly plant that handles the company's A3 sedan and cabrio, with the facility also handling final assembly of the TT ever since the factory opened in 1997 and the model began rolling off the line in '98. Last November, the plant in Hungary built its 500,000th TT, and now officials are ushering in the era of the new model.

Audi unveils A3 Sportback G-Tron with bi-fuel power, 808-mile range

By this time next year, the Audi A3 Sportback will be offered with a variety fuel-efficient powertrains ranging from diesel to the all-electric E-Tron, but perhaps the most interesting is the all-new G-Tron model, which uses Audi's innovative carbon-natural compressed natural gas called e-gas. Previously called A3 TCNG, we first heard about this technology last year, but now Audi has confirmed that this low-emission, sustainable-fuel will debut by the end of this year on the A3 Sportback G-Tron.
To create this e-gas, a plant in Werlte, Germany uses electricity to split water into hydrogen and oxygen. As hydrogen fuel cell vehicles become more popular, Audi says that this process could also be used to produce hydrogen fuel, but to create CNG, it mixes the hydrogen with carbon dioxide to create "synthetic methane." Since it is identical to the CNG available today, Audi's e-gas can be shipped and stored using the existing CNG infrastructure. Making the whole process even greener, Audi obtains the CO2 for this process from a nearby biogas plant, which would otherwise be released into the atmosphere.
Differentiated from the regular versions of the A3, the G-Tron features a pair of tanks under the rear cargo floor holding 15.43 pounds of CNG, which can power the car for almost 250 miles. What's more, the A3's conventional gasoline tank is still in place, giving the car an addition 560 miles of range. In total, that means the A3 G-Tron has a driving range of more than 800 miles. To run on both CNG and gas, Audi made changes to the car's 1.4-liter four-cylinder engine (including the turbo, cylinder head and fuel injection system) and catalytic converter.
