Audi TT Ultra Quattro Concept throws lightness at the problem

Audi is celebrating the 2013 Wörthersee Tour with a special concept version of the company's TT. The Audi TT Ultra Quattro concept tips the scales at just 2,449 pounds thanks to some extensive engineering work. The company pulled nearly 95 lbs from the car's body structure and used carbon-fiber reinforced plastics for many of its detachable body components. As a result, the concept weighs in at a full 220 pounds lighter than its production counterpart. Throw in a wicked turbocharged 2.0-liter four-cylinder engine with 310 horsepower and 295 pound-feet of torque, and you get a machine with the power to weight ratio in the supercar realm. 0-60 comes up in 4.2 seconds and top speed is listed at 173 mph.
Inside, the TT Ultra Quattro features plenty of carbon fiber trim, and designers also fitted the seats from the R8 GT to save a little weight. The buckets use CFRP for the seat frames, saving nearly 50 pounds in the process. In a world where automakers seem blind to the negative effect of throwing more heft at a vehicle, we're in love with the Ultra Quattro concept.

Munich prosecutors expand Audi investigation

Munich prosecutors said they have widened an investigation at Audi to examine the carmaker's sales in Germany and elsewhere in Europe after the federal government accused the Volkswagen division of cheating on emissions tests in its home market. Audi on Thursday recalled around 24,000 older A7 and A8 models in Europe, 14,000 of which were sold in Germany, to update transmission software, which it said was causing nitrogen oxide (NOx) emissions to exceed EU limits. Munich prosecutors have been investigating Audi on suspicion of fraud and criminal advertising in the United States where parent Volkswagen's emissions scandal broke in September 2015. They have expanded the inquiry to include vehicle sales in the brand's home region, a spokesman for prosecutors said. Audi said late on Thursday that it would continue to fully cooperate with authorities and Germany's KBA motor vehicle authority, which the carmaker had notified about the latest emissions irregularities. The affected Audi models with so-called Euro-5 emission standards, and built between 2009 and 2013, emit about twice the legal NOx limits when the steering wheel is turned more than 15 degrees, the German transport ministry said. Prosecutors said the suspicion in the Audi investigation still centered on fraud, adding they have not yet received updated information from the KBA on the situation in Germany. Their investigation came to a head in March when prosecutors searched Audi's headquarters in Ingolstadt in connection with the emissions scandal, as well as a second German plant and subsequently even the law firm that VW had hired to clear up dieselgate.Related Video: Government/Legal Green Audi Emissions volkswagen diesel

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.
