BMW replaces tri-turbo diesel with a quad turbo

Quad turbos have until now been the stuff of Bugattis. BMW is introducing a quad turbo diesel for the 7 Series, with nearly one hundred horsepower per turbo. It's all about making the six-cylinder 3.0-liter turbodiesel all as enticing a proposition as possible, and it faces strong competition from Audi's new twin-turbo V8 diesel available in the SQ7 TDI. The earlier, N57S engine (pictured above) utilized a triple-turbo setup good for 381 horsepower and 546 lb-ft. The new B57 version, confirmed by BMW at the 37th International Vienna Motor Symposium, adds yet another turbo for 394 hp and 561 lb-ft, and that massive torque is available from 2,000 to 3,000 rpm. It means the 7 Series gets from 0-60 mph in a snappy 4.5 seconds. The engine could produce even more torque, but 561 lb-ft is all the ZF 8HP 8-speed automatic transmission can handle. The N57S engine's dual-stage turbocharging setup consisted of one low-pressure turbocharger to take care of low-end torque, and two high-pressure turbos for the higher rev range. In the new B57 engine, the big turbo is now replaced with two smaller units on a common exhaust, to benefit from lower costs and smaller unit weight. In addition to the gains in power and torque, fuel economy has reportedly been improved by 5 percent. There are no reports yet whether the B57 TOP quad-turbo will make it to the US market, but customers in the European high end diesel saloon market will probably be very excited. Initially it will be available in the 750d xDrive version, and other top-end models like the 5 Series and the X5 will follow later on.

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.

What's up with this thought-controlled BMW i3?

Autonomous driving? A car being controlled by just verbal commands? One pilot program is going way beyond that this year with a car that can theoretically be mind-controlled. UK-based insurance-services company MoneySuperMarket is promoting something called "Epic Mind Drive." The project involves a BMW i3 electric vehicle (nice and futuristic) being rigged up with an autonomous driving system. Only instead of the system watching the road, it involves a person sitting in a seat outside of the car with an electroencephalography (EEG) neuro headset connected to the vehicle. In fact, that headset records brain activity and translates it into instructions. Those instructions are converted to radio frequency that's sent to the car to instruct it to perform various speed and turning duties. Apparently, yes, the car will be mind-controlled. Somehow. If this were intended for real-world use, it would go far beyond the autonomous-driving programs that have been in the works for the past couple of years. Nissan has been real active in that area, with chief Carlos Ghosn saying earlier this year that a "hands-free" car for heavy stop-and-go traffic may be available within the next couple of years. And last year, Google unveiled its autonomous car prototype (though it wasn't nearly as cool-looking as the Bimmer i3) while Tesla Motors has been making noise in that area as well. Besides the i3, MoneySuperMarket has developed the Epic Mind Drive mobile game that uses face-tracking technology to control a car on the screen. The idea with these two whiz-bang ideas is to get drivers to realize that they should think as they drive, it seems. As for the telepathic i3, we're as interested in details as the next website, so we checked out the two videos that are supposed to hype the project. While there is some groovy jazzy-electro music involved, the details of how this works are pretty much nonexistent (16 sensors, think to turn the wheel, and that's about it), so we look forward to hearing more about the project once it's underway.
