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 RS5 gets big turbocharged power and an angry new look

Menace has always been one of the keys to Audi's RS 5 coupe, from the fat wheel arches to the rumbling evocative exhaust note to the brutal straight-line performance. That's not going to change with the new version, but Audi is talking loudly and proudly about how the RS 5 debuts the new RS design language, partly in the hope that people don't labor on the disappearance of its V8 engine. Yes, the all-new RS 5 Coupe uses the same Porsche-engineered biturbo V6 as the Porsche Panamera, and uses it to such effect that it extracts 444 horsepower and 443 pound feet of torque from its 2.9 liters of displacement. Those 443 lb-ft is a full 125 more than the V8 could ever muster, and it's available from 1,900 rpm to 5,000 rpm. That kind of power is sufficient to push the RS 5 to 62 miles per hour in 3.9 seconds on the way to a limited 155-mph top speed (there's an optional 174-mph limiter, too). The all-wheel-drive Quattro RS 5 Coupe doesn't suffer much in performance in the switch from the naturally aspirated 4.2-liter V8 to the force feeding of a V6, but it remains to be proven whether the sound can be as captivating. The Porsche-sourced engine continues the current trend of "hot vee" engines, situating both of its turbochargers inside the vee-angle of the engine, and combines centrally-mounted direct fuel injectors with a short stroke to boost power and improve economy. The high-compression Miller-cycle motor also lets the RS 5 Coupe pull its consumption down 17 percent to 32 miles per gallon (or 197 grams/km of CO2 emissions) on the European driving cycle. Expect US mileage numbers to be significantly lower. The new RS 5 is also significantly lighter, pulling 132 pounds from the previous V8-powered model's mass, despite all the turbo plumbing, to weigh 3,649 pounds. A BMW M4-style carbon-fiber roof helps keep the weight down. Audi feeds its newfound V6 power through an eight-speed automatic transmission and permanent all-wheel drive, with 60 percent of the drive nominally headed to the rear end. The hard-turning sport differential is an option. Audi's reborn RS 5 rides on five-link suspension systems at both ends to keep suspension bits precisely location and improve ride quality, while sitting 0.8 inches lower than the standard A5 Coupe. It has the usual Audi Sport array of go-faster options for its go-fastest front-engined coupe, including the more aggressive Dynamic Ride Control damping system, carbon-ceramic brakes and sharper steering ratios.

This is the 2017 Audi S4 Avant

As we saw a few months ago, the new S4 sedan (which will go on sale in the US later this year as a 2017 model) ditches the supercharger and adopts turbocharging for its newly-developed V6. It also loses an option for a manual gearbox, and will only be available with an eight-speed automatic. As is the way of such things, the new wagon version (Avant in Audi-speak) doesn't differ from its sedan twin in any substantive mechanical way. There are two major differences. The first is of course the form factor; the second is where it will be sold. This is not an American proposition, so don't hold berate your local Audi dealer. If you want one, move to Europe after it goes on sale later this year. This is a shame, but not a surprise. Audi is in the midst of slotting a CUV into every possible micro-niche it can find, including the upcoming Q2 that the company teased this week. Unfortunately, that means Americans will miss out on the sizable cargo area (17.8 - 53.3 cubic feet, compared to just 17 cu ft in the S4 sedan's trunk) and lower center of gravity when compared to a typical CUV. If you want a S4 Avant here in the States, the closest you can get is the A4-based Allroad, which packs the familiar 2.0-liter TFSI engine and eight-speed auto. Too bad; the S4 Avant is a great-looking wagon.

Its newly developed turbo V6 engine outputs 260 kW (354 hp). New solutions in networking and assistance systems round out its features. Audi is transferring many technologies from the full-size class into the mid-size class. Lightweight and strong: the 3.0 TFSI The strong heart of the two new S models from Audi is a newly conceptualized 3.0 TFSI engine. The direct gasoline injection engine with turbocharging has an output of 260 kW (354 hp) and produces a hefty torque of 500 Nm (368.8 lb-ft) from 1,370 to 4,500 rpm. In terms of power and torque, it surpasses the previous model while achieving considerably lower figures in weight and fuel consumption. The turbo V6 engine accelerates the Audi S4 from 0 to 100 km/h (62.1 mph) in 4.7 seconds, and on up to an electronically governed top speed of 250 km/h (155.3 mph).
