Bathurst 12-hour gallery is GT3 heaven [w/video]

The 2015 Liqui-Moly Bathurst 12-Hour race was run this weekend at the Mt. Panorama Circuit in Bathurst, Australia. Race photographer Joel Strickland sent us a huge batch of photos, all of which make us salivate for the switch to GT3 rules in the United SportsCar Championship; the top seven finishers at Bathurst were of seven different makes: Nissan GT-R NISMO GT3, Audi R8-LMS Ultra, Aston Martin Vantage GT3, Bentley Continental GT3, Mercedes SLS AMG GT3, Ferrari F458 Italia and Lamborghini Gallardo. It was a sweet victory for the No. 35 car driven by the NISMO Athlete Global Team after it crashed in Saturday qualifying, and then was only in third place on the penultimate lap. The three-man driving team included two GT Academy winners, one of whom, Florian Strauss, has only been a professional race car driver for 18 months. It's the first time the GT-R has won at Panorama since the original R32 "Godzilla" took back-to-back wins in 1991 and 1992. Second place went to the No. 15 Phoenix Racing Audi R8-LMS Ultra, 2.4 seconds behind the winners, third to the Craft Bamboo Racing Aston Martin Vantage not even half a second behind the Audi. The Bentley Motorsport team, in its first Bathurst 12-Hour with two cars, had its No. 10 Continental GT3 in the lead until the penultimate lap and in second place until the final corner, but crossed the line in fourth after some rubbin'-is-racin' action from chasers. And if pictures aren't enough, as of writing you can still watch the live stream of the entire race at the Bathurst 12-Hour site. Or, if you don't have the time, at least be sure to check out the last five minutes, below. Enjoy.

To solve diesel problem, VW might need two fixes

Volkswagen says that a fix is on the way for its 11 million vehicles around the globe that are equipped with diesel engine software that can evade emissions tests. The problem might be far more complicated than simply creating a single solution for all of them, though. According to Automotive News citing Reuters, two remedies to cover different NOx-reducing systems could be necessary, and both potentially affect performance. Earlier examples of the EA 189 diesel engine used a lean NOx trap to reduce the harmful material coming from the tailpipe. According to experts in the Automotive News report, a software update might allow the engines to achieve compliance, but that could affect fuel economy. VW already tried this route once before the scandal came to light, but tests by the California Air Resources Board still showed the figures were too high. Later, some of the 2.0 TDI engines began using Selective Catalytic Reduction that reduced NOx by injecting a urea solution into the exhaust stream. According to Automotive News, a software update for this equipment might increase the amount of the substance used. Not only would that mean topping up the fluid more often, but there still could be some reduction in fuel economy. But, since the 2-liter, 4-cylinder TDI engine that sits inside the diesel vehicles first mentioned as being affected by the issue in the US don't have a urea treatment system, VW would need to install them into these cars. VW still hasn't officially outlined its solution (or solutions) to the emissions issue but is expected to soon. The automaker's long-term evasion of regulations with these diesel engines pumped vast quantities of additional NOx into the air. The substance is known to be linked with smog and acid rain. The US Department of Justice is already beginning an investigation into the company, and politicians are pushing for harsh punishments.

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.
