Next Audi R8 E-Tron could have 280-mile range

Just 265 miles of range on a single charge? Meh. That's what the folks at Audi might be saying about the Tesla Model S and its estimated range. Because the German automaker says the next iteration of the R8 E-Tron could go 450 kilometers on a charge, or about 281 miles. This information comes from Automotive News, which cites a presentation from Audi technology chief Ulrich Hackenberg at the company's annual press conference. The fact that the car will soon be available "upon request" is also news. The project was thought to be shelved until reports came out late last year saying that Audi figured out a way to upgrade its lithium-ion battery technology to double its range. Audi spokesman Brad Stertz said the company wasn't disclosing details related to if or when the car would reach North America or how much it would cost (we're guessing a really large number of dollars) but he did say it was notable that the project was back on track. Audi made news in the summer of 2012 when the R8 E-Tron set the "series production electric car" speed record with a 8:09.099 minute-time at Nurburgring thanks to a boosted top speed of more than 155 miles per hour.

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 Q7 testing gives us clearer view of new look

Audi just announced its intentions to build the Q1 in 2016. By that time, the company will already have introduced the opposing bookend to that subcompact utility vehicle, the fullsize Q7. The last time we saw the next-gen Audi Q7 out testing, our spy shots were very low quality and didn't reveal much about the luxury SUV. This time around we're able to make out a few key elements about the Q7.
For starters, the unfinished headlights have a stylish, wave-like lighting element with a three-dimensional appearance, while the rear of the Q7 will definitely get a similar wraparound liftgate as the current model. Overall, this prototype looks to be about the same size as the existing Q7, so it will be interesting to see how Audi squeezes almost 800 pounds from the SUV's curb weight. The diet will surely help improve efficiency, and we also hear that Audi is considering a plug-in hybrid model in addition to the standard gas and diesel variants.
Riding on a shared platform with the next-gen Volkswagen Touareg, Porsche Cayenne and the upcoming Bentley Falcon SUV, the next Audi Q7 is expected to bow in late 2014 for the 2015 model year.
