Audi kills off its 420-hp four-cylinder engine project

Audi's supercar-slapping, fire-breathing four-cylinder concept engine will remain just that, with Autoblog confirming that it has been internally killed off. Speaking at the launch of the TT RS, the engineering boss of Audi's Quattro GmbH division, Stephan Reil, said the Volkswagen Group had stopped all development of the 420-horsepower, 2.0-liter four it showed in the 2014 TT Quattro Sport Concept car (above). Despite previous assurances that Quattro had roles for both the EA888-based engine and Audi's wildly charismatic 2.5-liter, five-cylinder motor, post-Dieselgate reality has killed the smaller engine. "The 400-horsepower EA888 engine is dead," Reil said. The EA888 engine was conceived and developed by the same man behind AMG's powerhouse 2.0-liter four. Friedrich Eichler left AMG to become the Volkswagen Group's gasoline engine development go-to guy, and he was confident the 420-hp engine could be turned into a production car quickly, as was then-Audi development boss, Ulrich Hackenberg. It was even suggested that because the EA888 engine family bolted straight into the Volkswagen Group's ubiquitous MQB small-car architecture, the little powerhouse could be cheaply and quickly dropped into any of the company's cars that needed an image boost. Since then, Quattro has elevated the five-cylinder motor, switching it to an all-alloy block with a magnesium oil pan to cut down its weight while boosting its power and torque levels. Where the four-cylinder engine was shown with 420 hp and 332 lb-ft of torque, the production version of the TT RS's new five-cylinder engine totes 400 hp and 354 pound-feet of torque. The smaller engine's proponents claimed a 0-62 mph acceleration figure of just 3.7 seconds for the concept TT that carried it, and it might not be a coincidence that the all-new TT RS claims exactly the same figure. The 2.0-liter motor had a torque peak that arrived at 2,400 rpm and began to taper off at 6,300 rpm, while its power apexed at 6,700 rpm, thanks in part to a turbocharger that could feed it up to 1.8 bar of air. Flip to the TT RS' data and you're looking at more torque at lower revs and a touch less power, but at higher revs. That's not a lot of wriggle room for the concept engine to operate, especially when the perceived value of the five-cylinder engine is higher than the four, and the four's development and production costs would be higher than the five's.

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.

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.

Audi updates A3 with Virtual Cockpit, more goodies

Audi has announced a series of updates to the A3 family. And though we're still waiting for confirmation on its arrival here in North America following its introduction back in Europe next month, the revisions bode well for Ingolstadt's baby. Chief among the enhancements for the latest A3 is the inclusion, as promised, of the company's Virtual Cockpit infotainment system. One of our finalists for 2016 Tech of the Year, the Virtual Cockpit moves many of the controls and menus you'd expect to find in the center console display into the instrument cluster to make them easier for the driver to navigate (albeit at the expense of a co-pilot's assistance). Audi also used the occasion to install some of its latest driver assistance systems, including active lane assist, pedestrian protection, and available traffic jam assist that helps the vehicle crawl along in bumper-to-bumper conditions. The revised A3 also features new front and rear fascias, incorporating a sharper grille and new head- and taillights, with available Matrix LED units up front. Globally speaking, Audi is offering the updated model with six different engines – three gasoline and three diesel – including a 1.0-liter inline-three for the first time. There's the hybrid E-Tron model as well, and the flex-fuel G-Tron model that can run on natural gas. More enticing though is the new S3, which benefits from a ten-horsepower boost to produce a more substantial 310 hp and as much as 295 pound-feet of torque. With sedan, convertible, and three- and five-door hatchback bodystyles, that makes for a lot of combinations, though not all engines will be offered in all forms. Watch this space for word on US availability. In the meantime, you can scope out all the details on the various variants in the press release below and the high-resolution images in the exhaustive gallery above.
