The Audi R8 doesn't need turbos to visit Jay Leno's Garage

When Audi launched the original R8 in 2006, it caused a sensation. For its second go at the model, Audi skipped the V8 and went straight for ten-cylinder power in two states of tune: the V10 and the V10 Plus. Of course Jay Leno had the more potent of the two visit his garage. In V10 Plus trim, the Audi makes over 600 horsepower – all from a naturally-aspirated V10 in a segment increasingly dominated by turbocharging. Rivals like the Mercedes-AMG GT, Porsche 911 Turbo, McLaren 570S, and Ferrari 488 have all adopted turbochargers, which makes the R8 something of a modern-day Shelby Cobra, as Leno puts it. See what else he has to say in the video above – and don't forget to watch to the end to see how the launch control works.

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 will submit emissions fix for 3.0 TDI V6 to EPA and CARB

Audi will develop a software update for the emissions control system on Volkswagen Group's 3.0 TDI V6 and will submit the changes to the Environmental Protection Agency and California Air Resources Board for approval. If the government regulators accept it, the tweaks could end the emissions problems for an estimated 85,000 of these engines in the US in Audi, Porsche, and VW models. However, the stop-sale still covers these vehicles until further notice. Audi admits in its statement to failing to disclose three "auxiliary emission control devices" on the V6 to regulators, and US law considers one of these systems a defeat device. VW Group offered the engine in the US on the Audi A6, A7, A8, Q5, and Q7 since the 2009 model year. The mill was also available on the VW Touareg and Porsche Cayenne. The EPA filed a violation against the 3.0 TDI on November 2 because the agency reported that the engine's software contained a defeat device to circumvent emissions tests. The regulator recently extended that notice to cover these powerplants in the US from the 2009 to 2016 model years. Audi's statement vaguely estimates the price of this problem to be in the "mid-double-digit millions of euros," and the automaker could face financial punishment by regulators. "Determinations regarding potential penalties and other remedies will be assessed as part of the investigation EPA has opened in conjunction with the US Department of Justice," an EPA spokesperson told Automotive News.

That is the result of the discussions held between a delegation from AUDI AG and the US Environmental Protection Agency (EPA) and the California Air Resources Board (CARB). The updated software will be installed as soon as it is approved by the authorities. The three brands Audi, Porsche and Volkswagen are affected. Audi estimates that the related expense will be in the mid-double-digit millions of euros.
