BMW unleashes new M4 racer on DTM

We may not get to enjoy the fruits of it all, but we're in the midst of a golden age in touring car racing around the world. In Northern Europe, rival local series have amalgamated into the Scandinavian Touring Car Championship. In the UK, the British Touring Car Championship is enjoying the largest and most diverse grid in its long history. In Australia, the V8 Supercars series has grown from a Holden vs. Ford battle to include challengers from Mercedes, Nissan and Volvo. And in Germany, the DTM championship has managed to lure BMW back onto the grid to open up the battle between Mercedes and Audi. All good things, in short.
Since returning to the Deutsche Tourenwagen Masters in 2012, BMW has won the drivers' title once and the constructors' title twice, proving the Bavarian manufacturer to be not only a suitable challenger to the two-horse race between its star- and ring-emblazoned rivals, but the dominant force in German tin-top racing. Now BMW is set to enter its third season since returning to the DTM, and this is the car with which it intends to do so.
Replacing the M3 DTM that has impressively won half of the DTM races it has contested over the past two years, BMW's latest racing car is made in the mold of the new M4 coupe. Only it's even meaner. While the production version has switched to a turbo six, the DTM version still uses a V8: a 4.0-liter unit with four-valve cylinder heads, mandatory air restrictors and a Bosch ECU to channel 480 horsepower and 369 pound-feet of torque to the rear set of Hankook racing slicks through a six-speed sequential gearbox. The lightweight chassis is rounded out with competition-level aerodynamics and all the mandatory safety equipment.

Cadillac ATS-V and Mercedes-AMG C63 S pitted Head to Head

Our favorite (and only) Autoblog-alum-turned-Motor Trend staffer is back with another Head to Head video, this time pitting the Cadillac ATS-V with the Mercedes-AMG C63 S. This performance machine shootout is ostensibly a way to figure out which of these new super sedans will earn the right to go toe-to-toe with the undisputed champion of its segment, the BMW M3. In reality, it's just a really good excuse to put three of the hottest sedans on the market on video at the same time... and there's certainly nothing wrong with that. Jonny Lieberman spends time in each of the two new challengers on the road, picking apart their powertrains, chassis and driving dynamics on the kinds of twisty roads drivers of these cars will relish. Then, he hands the keys off to Randy Pobst, who sort of acts as an unmasked version of a certain tame racing driver, except that he talks and has a personality. 0-60 and quarter-mile times are equated, braking performance is measured and scores are tallied before the two sport sedans end up at Willow Springs raceway. Interestingly enough, the car that proves (just slightly) faster at the race track isn't the car that wins the comparison. Curious? We're not going to spoil it for you. Check out the video, above. Then, for more action of these two machines, check out the videos just below.

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.
