Audi to abandon CVTs?

The continuously variable transmission is one of those technologies that seems to make a lot of sense on paper, but in reality, almost always numbs the driving experience. That's one reason why Audi, according to reports, is planning to phase them out.
One of the first automakers to implement use of the CVT, Audi mates CVTs to larger engines than many other manufacturers, which typically install them on scooters, hybrids and small-displacement hatchbacks. But the time of the Audi CVT (which it calls Multimatic) may be near its end as a report from Australia indicates that Ingolstadt is moving toward a two-gearbox lineup that does not include the rubber-band transmission.
Instead, Audi is said to be focusing its attention on the S-tronic dual-clutch transmission and on conventional torque-converter automatics - although the development of beefier DCTs could spell the end of the Audi slushbox, as well. We've reached out to Audi for comment, so watch this space for confirmation.

US diesel model count to double for 2014?

While diesel cars are popular on most other continents, these less-complex alternative to hybrid-electric vehicles have yet to gain major traction in the US. As an increasing number of light cars and trucks start to offer these fuel-efficient engines, though, sales are expected to climb as well. While BMW, Mercedes-Benz and the Volkswagen Group (Volkswagen, Audi and Porsche) continue to lead the way, more non-German automakers like Mazda, Nissan, Chrysler and General Motors are starting to get serious about diesel in America.
TheDetroitBureau.com reports that the 2014 model year will see the number of diesel vehicles offered in the US double to about 40 nameplates, but the news gets even better for fans of these torquey and efficient powerplants. LMC Automotive has released data about future expectations of diesel cars in the US, and it predicts that sales should be very close to one million units in 2015 (up from an expected 600,000 units this year). By 2018, LMC's calculations suggest that sales will more than double from this year's expected totals accounting for almost 8 percent of new light-vehicle sales.

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.
