Next Audi RS4 to get V6 turbo, US sales still unclear

Audi's high-performance S models have forged a reputation in the US for offering wonderful driving dynamics in a package that doesn't scream, "I bought a sport sedan." However, its even higher-performance RS models are still somewhat of a rarity here. While the RS5 and RS7 are in the current US lineup, many of the wild RS models that Europe gets, like the RS6 Avant (pictured above), never make it to these shores. Unfortunately, that might not be changing anytime soon with the next-gen RS4.
The RS4 will follow the lead of the next BMW M3/M4 and (rumored) next Mercedes-Benz C-Class AMG and make the switch to a smaller turbocharged powerplant. According to an Audi insider speaking to Car and Driver, the next RS4 will drop the last generation's 4.2-liter V8 in favor of a turbocharged V6. The engine block will likely be shared with the supercharged 3.0-liter V6 in the regular S4 but fitted with two turbochargers. Power would likely be around 400 horsepower to match the 425-hp M3 and rumored 450-hp C-Class AMG.
Unfortunately, the RS might not make it across the pond to our waiting hands because the source says no decision has been made to export them yet. Obviously, we hope that Audi makes the right decision and brings the next RS4 here.

Audi already teasing, testing next R18 e-tron quattro

You can't debate Audi's record in endurance racing. With 12 victories at the 24 Hours of Le Mans, it comes second only to Porsche in the history books of the famous endurance race - only in Audi's case, all of those victories have come in the last 14 years, losing only twice: once to its partner team Bentley in 2003 and once to rival Peugeot in 2009. It's won the FIA World Endurance Championship in both of the seasons it's run so far, and has won championships in the European and American Le Mans Series, too.
That's quite a record to defend, and defend it Audi will with an evolved LMP1 racer next year. Only a week after tying up its second consecutive world championship, the German outfit is already back at Sebring this weekend testing the successor to the all-conquering R18 e-tron Quattro. Unfortunately as the new United SportsCar Championship doesn't include LMP1s, the only chance we may have to see it competing here in the United States will be at the 6 Hours of the Circuit of the Americas in September.
Audi is keeping mum on the details for the time being, releasing only this one photo and promising to reveal further details before the end of the month, but we can already discern a more streamlined shape, revised aero and reprofiled headlamps among the changes from the outgoing R18. One way or another, with Toyota upping its game and Porsche returning to top-level competition next season, Audi may be in for its toughest challenge yet - but you can bet it won't take it lying down. Scope out the press release below and watch this space for more.

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.
