BMW reveals M4 safety car with innovating water injection system [w/video]

Racing series don't just pick their safety cars at random, or use just whatever car is lying around. These days the car that sets the pace at the front of the pack is typically provided through consideration by a sponsor. In the MotoGP series, that's BMW and its M division, which have served up the Official Car of MotoGP since 1999. What you're looking at is the latest, and it packs some innovative technology on board. Aside from the matte black wrap with BMW's iconic striped livery, upgraded aero kit, retrofitted interior and emergency equipment, this BMW M4 coupe packs a new injection system under the hood. Only instead of injecting fuel, it injects water into the combustion chamber – something that wouldn't usually be recommended, but BMW insists actually aids in the combustion process. The idea is that the temperature of the air being mixed with the fuel inside the engine is usually hotter than ideal, so the system injects a fine mist of water into the collector in order to reduce the air's temperature... sort of like one of those hydrating misters at an amusement park or outdoor mall, but in an even hotter environment. The system brings the temperature of the air down to a more optimal temperature, helping it combust better. The process is said to yield a number of positive effects. For one, it reduces knocking. For another, it can make more out of lower-octane fuel where higher octane isn't available. It also can control the adverse effects of higher ambient temperature on the combustion process. But most of all, it increases output and reduce fuel consumption by around eight percent. Whether that eight percent is worth the added weight of the system – particularly with water pump and a 1.3-gallon tank in the trunk – is up for debate. But we'd imagine that the Bavarian engineers have weighed very carefully. Of course there's also the matter of refilling the water tank, which BMW says would be carried out whenever the safety car is refueled, but in real-world conditions would only necessitate attention once every five top-ups at the gas station. By now you might have guessed that BMW probably didn't develop this system just for the MotoGP safety car, and isn't planning on keeping it confined to the racetrack. Instead it's being tested and demonstrated on the safety car before being rolled out on production models in the future.

Rinspeed Budii Concept is a rolling smorgasbord of future tech [w/video]

There's a strange dichotomy going on inside the Rinspeed Budii Concept. Actually, there's a slew of seemingly mismatched ideas, but that seems par for the course when it comes to the mind of Frank Rinderknecht, no? For instance, there's a manual-wind Manero PowerReserve watch embedded in the cabin, which seems quaint, considering the high-tech nature of the car's design and intent. A high-resolution camera apparently "recognizes" when the watch is getting low on power, and a robotic arm "uses ingenious motions to wind the movement" of the watch. Seriously. The aforementioned robotic arm is a seven-axis unit that can "reach out" to the driver or passenger so that they can take over driving duties from the autonomous car. In this way, the occupants can choose to put their lives under the control of the "cognitive and intuitive autopilot" provided by a telescoping laser scanner and a high-res camera that map the car's surroundings, or to make their own "ethical" driving decisions. We kind of assume that refers to the current autonomous-driving question of the times: whether or not to save the lives inside the car our outside of it in case of emergency. If all of that sounds suitably high-tech, you should also know that the "feel-good lounge atmosphere" of the interior features removable plexiglass work surfaces inside, folding blinds for privacy that are custom printed with user-selectable designs, air outlets with ambient lighting, a "wellness shower in the headliner" (whatever that means) and a center console with – you guessed it – cup holders. The platform on which all of this is based is the all-electric BMW i3 hatchback. If all of that sounds intriguing, we suggest you read all about it in the press release below and take it all in via the included image galleries. Rinspeed "Budii" redefines human-machine interaction Reach out to robots The vision of autonomous driving will soon become reality and will fundamentally change the interaction of man and automobiles. While the research centers of the automotive industry are still feverishly working on the technical solutions, progressive thinkers such as the Swiss idea factory Rinspeed are already giving concrete thought to how automated private transport will transform the car and the man-machine system. Besides fundamental conceptual changes, this will also have to involve issues of ethics and society. In the past, the robots in the factories of this world merely assembled cars for people.

BMW ready to bring more i3, i8 plug-ins to US

BMW has found a receptive audience for its first batches of plug-in vehicles in the good 'ole USA. The German automaker, which started selling its first mass-produced i plug-ins in Europe late last year, will send a higher percentage of those vehicles to the US because of strong demand here, according to Automotive News, which talked with BMW executive Ian Robertson. And the Americans might cause Bimmer to speed up production, to boot. BMW makes the i3 electric vehicle and i8 plug-in hybrid in Germany, and has sold about 10,000 units of the former and 280 of the latter worldwide. Since August, BMW has been selling about 1,000 i3s a month in the US (it sold just 58 i8s in September). The bigger story, though, may be that Bimmer has sold out of its US allocation of i8s through the end of next year. Pretty heady stuff for a car that starts at around $137,000. Currently, BMW builds around 100 i-series vehicles a day in Germany, and may speed up production of the i8 for the aforementioned reason. As for the i3, which comes with an option of a gas-powered range extender, we'd reported earlier this year that the waitlist for that model had grown to about six months. Our i3 First Drive report is here if you'd like to know what all the fuss is about.
