Xcar weighs in on the five best-sounding modern cars

Getting behind the wheel of a well-balanced vehicle can be a wonderfully visceral experience, thanks to the combined feeling of things like the weight of the steering, the bite of the brakes, and, of course, the roar of the engine. Unfortunately, many of the sensations of driving require actually being in the driver's seat to understand them, but thankfully the intoxicating noise of a beautifully tuned internal combustion engine can be shared with everyone. In a new video, Xcar shares their opinion on the five best-sounding modern performance cars. The list is a symphony of horsepower. As opposed to keeping all of the vehicles brand new, Xcar actually picks a few that are recently off the market. They're all definitely champs, though. While the list itself is well stocked, you might be able to argue with the specific order, and it would be nice to hear a few participants from outside of Europe for a collection like this one, too. No matter. Every listener is sure to find something they like in the bunch, though. Turn up the volume and enjoy.

Recharge Wrap-up: Ferrock a carbon-negative cement substitute, Audi makes e-diesel

A cement alternative uses recycled materials and traps CO2 rather than producing it. Invented by David Stone at the University of Arizona, Ferrock uses recycled steel dust and glass to produce a substance stronger than conventional concrete. Cement has a high carbon footprint from the high heat needed to process the limestone. Ferrock needs no such heat, and it actually uses CO2 to harden, making it, as Stone calls it, a carbon-negative material.

Part of the Firmware 6.2 update, Valet Mode allows the owner to disable certain performance features and block personal information when letting someone else drive the car. It limits the car's to speed to 70 miles per hour, and caps output at 80 kW. It can also disable mobile app access, Homelink, Bluetooth and wifi and the "Places" function, which stores addresses for you. The folks at Teslarati did find some shortcomings in the new feature, though. Read more at Teslarati. Audi has produced its first batch of e-diesel made from water and CO2. The fuel is made by reacting hydrogen from the water with CO2 to make long-chain hydrocarbon compounds called "blue crude." That can then be refined similarly to crude oil to make e-diesel, which is a fuel free from sulfur and aromatic hydrocarbons. That e-diesel can be used on its own, or mixed with fossil fuel diesel to power a vehicle. "In developing Audi e-diesel we are promoting another fuel based on CO2 that will allow long-distance mobility with virtually no impact on the climate," says Audi Head of Sustainable Product Development Reiner Mangold.

Fuel of the future: Research facility in Dresden produces first batch of Audi e-diesel - The verdict: Pilot plant produces high-quality diesel fuel - No need for mineral oil: e-diesel made from water, CO2 and green power - Minister Wanka: "Synthetic diesel using CO2 is a huge success" Audi has taken another big step in the development of new, CO2 neutral fuels: A pilot plant in Dresden has started production of the synthetic fuel Audi e diesel. After a commissioning phase of just four months, the research facility in Dresden started producing its first batches of high-quality diesel fuel a few days ago. To demonstrate its suitability for everyday use, Federal Minister of Education and Research Prof.

Audi to use this telepresence robot to fix cars

Next time you take your Audi in for service, watch to see if a little white stand is following your mechanic around. It's not some new measurement tool for your car; it's a actually a robot being controlled remotely to improve vehicle service. While bots playing a role in building cars is nothing new, the company is taking things a step further in the US by introducing Audi Robotic Telepresence to assist dealer technicians in repairing the brand's vehicles. The droids are already being used in a pilot program at about 18 dealers nationwide with plans to have it at 100 in the near future.
At the moment, ART, as its called, is more R2-D2 than The Terminator. It certainly won't be doing any wrenching on your A4 anytime soon because it doesn't even have arms. Instead, the robot comprises a remote-controlled stand with multiple cameras, a microphone and speakers. The bot is operated remotely by Audi Technical Assistance consultants and Technical Field Managers who can talk back-and-forth with mechanics about vehicle service and help to remotely diagnose problems. The droid is even equipped with a handheld camera and borescope to reach into tiny crevices.
Audi claims that ART is the first system of its kind to directly link automakers with technicians at the dealer level in this way and leads to faster, more accurate service for customers. Scroll down to watch a video of the bot in action and read the release for the current list of participating dealers.
