Uber releases fleet of self-driving vehicles to select few in Pittsburgh

Starting today, a select group of Uber users in Pittsburgh, PA will have the ability to request a self-driving vehicle. If a self-driving vehicle is in the area, Uber will send it, as well as a safety driver, to drive loyal customers to their destination. The announcement to give customers the opportunity to get a ride in one of Uber's self-driving vehicles comes roughly a year and a half after the company set up its Advanced Technologies Center in the city. On Tuesday, the company offered a few members of the press the opportunity to ride in one of the company's self-driving cars. The fleet, despite Uber's collaboration with Volvo, was comprised of 14 Ford Fusions equipped with a host of self-driving technology, reports TechCrunch. Uber is giving away free rides as a way to obtain real-world testing, which is crucial for self-driving technology. Recently, nuTonomoy beat Uber to the punch by launching the world's first autonomous taxis in Singapore. While the choice to release its self-driving cars in Pittsburgh mainly comes down to the fact that its ATC is located there, the city faces four seasons and its difficult streets that are comprised of bridges, railroad lines, and an irregular grid layout will prove to be a challenge for the autonomous cars. Since the self-driving vehicles are still being tested, the cars will come with two full-time Uber employees. One employee will loosely grasp the car's steering wheel, ready to take over if something goes awry, while the other will monitor the computer's software. As TechCrunch points out, Uber's autonomous vehicles drove in a similar manner to a regular driver. It obeyed traffic laws, mimicked a driver by coming to stops gently and at other times abruptly, as well as driving slightly into another lane to dodge a poorly-parked vehicle, reports TechCrunch. There's no word on whether regular Uber customers will get a ride in one of the company's Fusions or one of the Volvo's that its working on. Automakers and companies alike have been in a race to put autonomous vehicles on the road. Tesla recently updated its Autopilot system, Apple laid off dozens of employees to reboot its self-driving car project, and Google is working giving its autonomous vehicle the ability to detect emergency vehicles. While this is a large step for Uber, vehicles with autonomous capabilities still have a long way to go.

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.

Ford director says company has big efficiency plans, but no dedicated EV

The annual autofest known as the North American International Auto Show previews a plethora of exciting new products that we'll see and drive later in the year, from tiny urban commuters to family sedans and crossovers to hard-working big pickups and SUVs. It's also a once-a-year cornucopia of auto executives and leaders from around the world. "There will be some really fun stuff that you'll hear about in the future" - Ford's Kevin Layden So, in-between dozens of cool new-product unveilings on rotating stages during the two press days preceding the public show, we auto scribes grab what planned and impromptu interviews we can. Sessions with top industry leaders can be hard to get, but I was able to score a seat in a group session with then-General Motors North America president (now executive VP of global product development) Mark Reuss, and I also managed brief one-on-ones with a trio of vehicle electrification leaders, one each from Ford, BMW and GM, and what they said then remains relevant now. First up is Kevin Layden, Ford's Director of Electrified Powertrain Engineering. ABG: Where will Ford go beyond its current Focus EV and hybrids, and will there be a Ford EV and/or hybrid on its own energy-optimized platform one day. KL: We don't want to do a dedicated electric vehicle with all the development costs borne by a niche product. At the Michigan Assembly plant right now we're building the Focus electric, PHEV and EcoBoost on the same assembly line. Also the C-Max, with both a hybrid and an Energi plug-in, and we use that same power pack in the Fusion Hybrid and Energi. We want to be, "The power of choice" [a Ford marketing slogan], so having that choice for customers is very important. And if I want to sell the Fusion, Focus and C-Max globally, we can use these power packs wherever it makes sense. So as we go forward, you'll see us proliferating the power packs we have today. Then the question is, what do we do next? There will be some really fun stuff that you'll hear about in the future. ABG: Is the efficiency difference between a dedicated ultra-efficient vehicle platform and a shared multi-use platform getting smaller as all platforms get more efficient? KL: Exactly. Were going through aero studies now on wheels and tires and hood sealers on base vehicles. We have full aerodynamic wind tunnel studies going on with the base Focus and C-Max, so all of that [aerodynamic improvement] will be there for EVs.
