Car Hacking 101: Here's what motorists should know [w/video]

Cars are nothing more than computers on wheels. As such, they're vulnerable to hackers. Most people who work within the auto industry have understood this for years, but for the broader American public not paying as close attention, three storylines emerged recently that underscored this new vehicular reality. First, German researchers found a flaw in BMWs remote-services system that allowed them to access the telematics units in vehicles. Then, a 60 Minutes report demonstrated that researchers could remotely infiltrate a Chevy Impala and override critical functions, like acceleration and braking. Finally, a US Senator released a critical report (see video above) that found almost all automakers are unprepared to handle real-time hacks of their vehicles. Those reports come on the heels of two previous instances in recent months when researchers demonstrated the capability to hack cars. All this news can be disconcerting. If you're late to the concept of car-hacking and wondering how this is possible, we've got you covered. Here's your quick primer on what you need to know. 1. How Did My Car Become A Computer? On the outside, cars haven't changed all that much over the past couple of decades years. On the inside, however, the amount of electronics and software has dramatically increased. Most new cars contain more than 50 microprocessors known as electronic control units. These ECUs control everything from airbag deployment and navigation systems to throttle control and braking, and they're usually connected to each other on an internal network called the CAN bus. 2. What Exactly Is Car Hacking? Depends who you ask. Automakers might consider anything that alters the car from its state of manufacture as a 'hack.' For example, if you're chipping the engine – re-calibrating those ECUs to increase your horsepower – some people might consider that a hack. But in the context of the recent news reports, security experts are focused on unwanted, unauthorized cyber intrusions into a vehicle. Once inside your car, prospective attacks could range from minor things like eavesdropping on conversations via an infotainment system and unlocking car doors to major concerns, like overriding driver inputs and controlling braking, steering and acceleration. 3. How Is This All Possible? Any part of the car that communicates with the outside world, either via a remote or direct connection, is a potential entry point for hackers.

Mazda3 versus BMW 1 Series and Audi A3 in Euro diesel showdown

It's not exactly a Tesla Model S taking on a Ferrari, but for us green enthusiasts, a drag race and comparison between reasonably priced diesel hatchbacks does hold interest, and UK's Auto Express was kind enough to do the deed. When raced, the diesels actually laid a little rubber coming off the line, though the track was covered in rain. Did we mention it was in the UK? The comparison was between diesel hatchbacks priced at less than 22,000 British pounds (about $34,500 US), and Auto Express pitted a Mazda3, a BMW 1-Series and an Audi A3 against each other. The results are revealed in the 11-minute video you can watch below. In short, one car smoked the others. In order to set the tone, you should know that the Mazda's 150 horsepower is about 35 more than the other two entrants. The Mazda also earned points for its quiet motor (it sounds more like a petrol engine, the host says), standard equipment that would add about $4,000 to the other two cars if included and relative roominess in front and in back. The Audi gained points for its storage space, while the BMW had the only rear-wheel-drive car in the hunt. See for yourself how the competition stacks up.

Ferrari, BMW lend expertise to Olympic bobsled, skeleton, luge

LONDON — There are plenty of reasons why the sport of bobsleigh is sometimes referred to as Formula One on ice, but few as obvious as Italy's World Cup sleds. Resplendent in Ferrari red, and with a set of team sponsor Pirelli's P-Zero tyres painted on the sides, they are even liveried to look like racing cars. Ferrari, Formula One's most glamorous and successful team, have worked with the Italian federation, whose sleds run without sponsor branding at the Olympics, since 2010 and in the run-up to next month's Pyeongchang Winter Games. Former rival BMW, title sponsor of the World Cup, has long partnered the U.S. bobsleigh team, while McLaren teamed up with Britain's bob and skeleton athletes for the 2014 Sochi Games in Russia. "There's always the link between the Formula One companies, or any motor company, and skeleton and bobsleigh," says Rachel Blackburn, the engineer who has been involved in Britain's skeleton program since 2006 and who used to work for McLaren. "There's the Ferrari sleds and the BMW sleds ... when we were at McLaren it kind of made a good story," she told Reuters by telephone from her home in Dubai. That somewhat manufactured rivalry has died down in the years since Sochi, with McLaren no longer involved and Ferrari's presence low key. But the worlds of grand prix motor racing and sliding sports still have plenty in common. Bobsled, luge and skeleton are among the fastest of Olympic sports, with bobsleds reaching speeds over 90 mph. Drivers are subjected to gut-wrenching G-forces, and crashes can be fatal. And then there is the ongoing debate about cost controls, the direction of future rules, preserving a level playing field and obsessive secrecy — all endlessly recurring themes in Formula One. 80 mph on a tea tray Blackburn said skeleton, where riders hit 80 mph on what has glibly been compared to an oversized tea-tray, sits somewhere between Americas Cup yachts and Formula One cars in terms of speed and aerodynamics. "Applied engineering is far more interesting than the pure stuff, so when its applied to something that's fun and exciting it does make it a lot easier to solve problems," she said. "There is the Americas Cup, sailing, Formula One and the high speed ice sports as well. It's the same concept.
