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.

eBay Find of the Day: Mk1 Ford GT40 with interesting history

You might expect a rare Ford GT40 to cross the block at some sort of prestigious auto auction from RM or Gooding, not show up on eBay for over $2 million. However, that's exactly what we have here. The seller claims the car is a late-build Mk1 GT40 from 1969, and it's currently owned by the director of the Hublot watch company in Switzerland.
According to the listing, GT40 #P1108 started life as Mk1 car that was built from factory spares in 1969 and was first sold in 1971. However, the auction is somewhat confusing. According to an image in its gallery, the vehicle was actually built from one of the seven spare Mk3 tubs when production of the iconic racers ended.
This GT40 was never built as a racecar - it lived on the streets its whole life. After assembly finished, it was sent to Germany and was eventually registered for the road. The first owner kept the car until 2005 and sold it with 7,300 miles on the odometer. The current owner bought it in 2012.

A cool boost to turbocharger performance

Since the advent of the forced-induction engine, we have been looking for ways to get every drop of performance we can. There are many approaches to getting additional power using better intercooling, water injection, or even adding nitrous oxide. One take on a short instant burst of power is being researched by Mahle and involves providing supercooled air to an engine, which allows it to burn a leaner fuel mixture and produce more power. The supercooling idea is not new and was examined by Ford in 1993 on the Mustang Mach III concept car, then brought up again in 2003 with the SVT F-150 Lightning concept. Ford called its system the SuperCooler; it was designed to work with any turbocharged or supercharged engine equipped with a water-to-air intercooler. The system on the Lightning concept used a small tank of antifreeze that was hooked up to the truck air conditioning compressor. The air conditioning compressor cooled the antifreeze down to about 30 degrees. The other side of the tank was hooked up to the air-to-water intercooler, which usually had a temperature over 100 degrees. Once the antifreeze was circulated from the tank into the intercooler, it would lower the intercooler temperature and provide for a cooler, denser air charge into the engine; the result was around 50 extra horsepower for a burst of about 30 seconds to a minute, depending on the size of the tank. The system for the Lightning was to be offered as a $750 option and would have been targeted towards drag racers and the like, as it could be used for a run down the drag strip and then re-cooled by the time the truck was back in line. The system was fairly non-intrusive – it only weighed about 25 pounds and did not require a new compressor or intercooler. But as with many concepts, it was ultimately scrapped. The technology was always stuck in the back of my mind, but with larger and more powerful engines being produced it could not find its place. With the advent of new fuel economy standards, we have seen small-displacement turbocharged engines pop up and they seem like the perfect candidate for this type of technology. Ford's EcoBoost 1.0-liter three-cylinder turbocharged engine, as used in the Fiesta and Focus, is one such candidate for this technology. It would add a negligent amount of weight but could provide a boost of 10 to 20 horsepower when needed, like merging onto the highway or catching up to traffic.
