The next-generation wearable will be your car

This year's CES has had a heavy emphasis on the class of device known as the "wearable" – think about the Apple Watch, or Fitbit, if that's helpful. These devices usually piggyback off of a smartphone's hardware or some other data connection and utilize various onboard sensors and feedback devices to interact with the wearer. In the case of the Fitbit, it's health tracking through sensors that monitor your pulse and movement; for the Apple Watch and similar devices, it's all that and some more. Manufacturers seem to be developing a consensus that vehicles should be taking on some of a wearable's functionality. As evidenced by Volvo's newly announced tie-up with the Microsoft Band 2 fitness tracking wearable, car manufacturers are starting to explore how wearable devices will help drivers. The On Call app brings voice commands, spoken into the Band 2, into the mix. It'll allow you to pass an address from your smartphone's agenda right to your Volvo's nav system, or to preheat your car. Eventually, Volvo would like your car to learn things about your routines, and communicate back to you – or even, improvise to help you wake up earlier to avoid that traffic that might make you late. Do you need to buy a device, like the $249 Band 2, and always wear it to have these sorts of interactions with your car? Despite the emphasis on wearables, CES 2016 has also given us a glimmer of a vehicle future that cuts out the wearable middleman entirely. Take Audi's new Fit Driver project. The goal is to reduce driver stress levels, prevent driver fatigue, and provide a relaxing interior environment by adjusting cabin elements like seat massage, climate control, and even the interior lighting. While it focuses on a wearable device to monitor heart rate and skin temperature, the Audi itself will use on-board sensors to examine driving style and breathing rate as well as external conditions – the weather, traffic, that sort of thing. Could the seats measure skin temperature? Could the seatbelt measure heart rate? Seems like Audi might not need the wearable at all – the car's already doing most of the work. Whether there's a device on a driver's wrist or not, manufacturers seem to be developing a consensus that vehicles should be taking on some of a wearable's functionality.

Ford finds flex-fuel engine design plays big role in emissions output

How bad is ethanol for your engine? There's been a lot of debate on this issue as the US considers upping the biofuel content in the national gasoline supply from 10 percent (E10) to 15 percent (E15). The ethanol industry and some scientists say higher ethanol blends show no "meaningful differences" in new engines while the oil industry says ethanol creates health risks. Researchers working at the Ford Research and Innovation Center decided to take a closer look at how a wide range of gas-ethanol blends - E0, E10, E20, E30, E40, E55 and E80 - affected the emissions coming out of a flex-fuel 2006 Mercury Grand Marquis. To see the full report, printed in the journal Environmental Science & Technology, requires payment, but there is an abstract and Green Car Congress has some more details. The gist is that, "with increasing ethanol content in the fuel, the tailpipe emissions of ethanol, acetaldehyde, formaldehyde, methane, and ammonia increased." At least NOx and NMHC emissions decreased. The researchers say that the effects are due to the fuel and "are expected for all FFVs," but that the way that a manufacturer calibrates the engine will affect NOx, THC, and NMOG emissions. It's this last bit that's important, since the researchers found, "Higher ethanol content in gasoline affects several fundamental fuel properties that can impact emissions. ... These changes can have positive or negative effects that can depend on engine design, hardware, and control strategy. In addition to direct emissions impacts, higher ethanol content fuel can also provide more efficient combustion and overall engine operation under part-load conditions and under knock-limited higher-load conditions." So, as we head towards more ethanol in our fuel supply (maybe), manufacturers are going to need to learn how to burn it most efficiently.

Autoblog's June 2019 Editors' Picks

Each year we review, test and rate hundreds of brand-new cars, trucks and SUVs. We rate these vehicles using the Autoblog score, giving a select few our Editors’ Pick. Here are the best cars we drove in June 2019. 2019 BMW 8 Series Everyone on the Autoblog staff loves a good grand tourer, so we were excited to get behind the wheel of the revived BMW 8 Series, specifically an M850i Coupe. A good GT needs to be as fast as it is stylish and comfortable, and the new 8 Series delivers. We particularly like the 523-horsepower twin-turbo 4.4-liter V8Â’s copious power and smooth ride quality, even on MichiganÂ’s pockmarked post-winter roads. We dig the interior design, too, though not everyone was in love with the exterior. ItÂ’s not the best-handling car in its class, and doesnÂ’t hide its sizable proportions very well, but itÂ’s still worth a look if youÂ’re looking for a big, fast cruiser.  2019 Ford Expedition Crossovers may be the hottest vehicles on the market, but thereÂ’s still a sizable demand for traditional body-on-frame SUVs like the Ford Expedition. These behemoths offer plenty of space in addition to truck-like capability. We like the Expedition's smooth ride, powerful twin-turbo V6 and sharp exterior design, though the interior can feel a bit cheap, especially on some of the more expensive trims. Adding options quickly puts it into Lincoln Navigator territory, and itÂ’s hard to recommend the Ford over the Lincoln when the latter packs the same capability into a far nicer package. Still, the Expedition is as good or better than the competition in most respects, and thatÂ’s why itÂ’s one of our picks. 2019 Toyota 86 Few cars at any price point are as much fun as the Toyota 86 (and its twin, the Subaru BRZ). We like the 86Â’s balanced chassis and sharp steering, and while itÂ’s not as nimble as its close rival the Mazda MX-5 Miata, the ToyotaÂ’s back seat and trunk make it a more usable vehicle. But while we like the 86Â’s driving position, the rest of the interior feels cheap and dated, especially the infotainment system. We complained about the anemic powertrain back in 2012, and itÂ’s only gotten worse as the years have gone by.
