Audi A3 G-Tron offers big range, few emissions

Audi is exploring a variety of sustainable transportation technologies beyond the traditional diesel, hybrid, plug-in and electric options, including the compressed natural gas A3 Sportback G-Tron that debuted today at the Geneva Motor Show.
The most interesting thing about this rather innocuous-looking A3 Sportback is that when run on Audi e-gas, the car becomes completely carbon neutral, emitting no more CO2 than was chemically input in this special fuel's production. Audi has already broken ground on a new plant - powered by renewable energy, of course - that uses electrolysis to produce e-gas, which could then be made available through any natural gas distribution network.

Audi TT Offroad gets the green light

The TT family already has a coupe and convertible, with various engines available in each. But over the past year or so, Audi has been toying with the idea of expanding the range with another bodystyle. And now the latest report from Car confirms that Ingoldtadt has given the production go-ahead to the TT Offroad concept. Unveiled at the Beijing Motor Show last year, the yellow TT Offroad concept envisioned a high-riding five-door crossover form with trademark TT styling cues. It was preceded by the blue three-door Allroad Shooting Brake concept at the Detroit show and followed by the sleek, red five-door TT Sportbrake concept at the Paris salon later the same year, but the impracticality of both those show cars is what we understand prompted Audi to go with the Offroad concept instead. So if it's a crossover, why not badge it with the letter Q, you ask? Because Fiat, that's why. The Italian automaker owns the names Q2 and Q4, which it has used on a variety of models (particularly Alfa Romeos and Maseratis) to connote their traction system. And though the Volkswagen Group has asked nicely, Sergio Marchionne has been as reluctant to give his biggest rivals a leg up as he has been to part with Alfa Romeo, despite their repeated advances. As a result, word has it that the production version of the TT Offroad concept will be sold as the TTQ, which kinda makes us giggle, but it would at least provide a nomenclature bridge between the TT and Q families within Audi's lineup. That is, unless Audi marketing chief Luca de Meo manages to convince his former boss to part with the Q2 and/or Q4 labels. Whatever it's called, the production crossover coupe would share similar dimensions to the Q3 when it arrives in 2017, but would potentially stand even further apart from its more utilitarian counterpart than the BMW X4 does from the X3 on which it is based.

Are future vehicular hacks inevitable?

Before the hack of the Uconnect system in a Jeep Cherokee resulted in a 1.4-million vehicle recall, the potential software vulnerabilities in vehicles were already a hot topic with Congressional inquiries and even proposed legislation in the US. As cars' interconnected systems gain the ability to go online, they become open to a host of new threats. Automakers are trying to stop this, but it might be too late to put the genie back into the bottle. Throughout 2015, the issue of software security in vehicles has become increasingly vital. For example, the recent Jeep case wasn't even the biggest hack this year. In February, a major flaw was discovered in the BMW Connected Drive service that allowed researchers to remotely lock and unlock the doors and potentially affected 2.2 million cars. The fix was an over-the-air patch for the problem. Automakers are actively working to fix the issues. Mercedes-Benz, BMW, and Audi reportedly are using encrypted connections and firewalls in their vehicles to prevent hacking. "Absolute, 100-percent safety isn't possible," Daimler spokesperson Benjamin Oberkersch said to Automotive News Europe. "But we develop our systems, tested by internal and external experts, so they're up to date." These vulnerabilities seem to be popping up more often. A successful hack took $14 in parts from Radio Shack in one case. There was also a 60 Minutes report earlier in the year about DARPA's ability to hack into OnStar to take control of a Chevrolet Impala. Experts aren't so sure companies can contend with hackers' advancement. "The difficulty for the carmakers at the moment is the question whether they can keep pace with advances in technology, and especially hacking technology," Rainer Scholz, executive director for telematics consultant EY, said to Automotive News Europe. "We seriously doubt they can." At this point, vehicle hacks are coming more from researchers looking for holes than from those with malicious intent. Still, the vulnerabilities are definitely there. It's up to automakers to keep patching the problems before they become dangerous to drivers.
