Audi A4 on 2040-cars

The 2013 Rolex 24-hour race at Daytona comes down to the last hour [spoilers, w/video]

It took 24 hours to run the race, but it was the last one was stuffed with the high action as four cars were still trying to figure out how to gain victory on the track and in the pits. Along with the obligatory crashes, spins, mechanical issues and retirements had come numerous penalties, a double-digit number of full-course yellows and two hours of fog that turned early Sunday morning into a stretch of parade laps.
The final hour would make up for the morning - drivers who might have been happy just to get on the podium had a shot at victory as the end of the race approached, and that turned into a few gambles that paid off, and at least one that didn't...

Audi plans RS3 for US

Rejoice, performance-car fans. The Audi RS3 (pictured above) is probably coming across the Atlantic. If that happens, the US-market RS3 will likely be a sedan, not the five-door body style offered in Europe. Hot hatch fans might shed a tear at this news, but we'll the RS3 any way we can get it. Audi of America CEO Scott Keogh feels the same way. "We really, really want the RS3," he said to Automotive News. "I'm very confident we'll see that car in the market. That's as far as I'm going to go. In Europe, the RS3 Sportback packs a 2.5-liter turbocharged five-cylinder with 362 horsepower and 343 pound-feet of torque mated to a seven-speed dual-clutch gearbox. That grunt get to the ground via a torque-vectoring all-wheel drive system that can route up to 100 percent of the power to the rear wheels when necessary. The sprint to 62 miles per hour goes by in just 4.3 seconds. Of course, a tiny, hardcore sedan isn't on every buyer's shopping list. For those who want a little more room with their luxury, the Q8 is also on the way. "That is absolutely a car that we will see in the United States," Keogh said to Automotive News. The big crossover shares its platform with the next Q7, but will have sleeker bodywork similar to vehicles like the BMW X6 and Mercedes-Benz GLE Coupe. The Q8 is slated to launch in 2017 with US sales following the European debut. Recent rumors suggest that a fully electric E-Tron version could be part of the lineup as well. Audi's American arm isn't as crossover crazy as some other automakers, however. According to Keogh, the tiny Q1 CUV might not come to the US because it's not the right fit for the market.

VW orders external probe into diesel emission scandal

There are well over 480,000 Volkswagen-made, diesel-powered vehicles currently traveling roads in the United States that do not meet the Environmental Protection Agency's emissions requirements. This, as you can probably imagine, is a very big deal, and has led VW CEO Professor Doctor Martin Winterkorn to release an official statement on the matter. "I personally am deeply sorry that we have broken the trust of our customers and the public," he said. It's important to note that these vehicles run software with a so-called "defeat device" that kicks in when the on-board computer senses that it is being tested for emissions. When the car is operating normally – in other words, when its exhaust isn't being sniffed – the cars do not meet US emissions standards. According to the EPA and the California Air Resources Board, affected cars emit as much as 40 times the allowable level of certain pollutants. "We will cooperate fully with the responsible agencies, with transparency and urgency, to clearly, openly, and completely establish all of the facts of this case," according to Winterkorn, who added, "Volkswagen has ordered an external investigation of this matter." It's not yet known who will carry out this investigation. At present, there are still a number of 2015 Volkswagen models on dealer lots that do not meet emissions requirements. VW has issued a stop sale on vehicles equipped with the 2.0-liter TDI diesel engine. What's more, the German automaker has been barred from selling 2016 model-year vehicles that use this engine, according to The Detroit News. Last year, diesel vehicles made up about 22 percent of all VW sales, which means these restrictions will have a big impact on the brand's sales performance until a remedy is found and the vehicles are approved for sale. Interestingly, the EPA has started a campaign of sorts to test vehicles from other automakers that sell diesel-powered vehicles in the United States to make sure they comply with emissions requirements under all operating circumstances. The EPA says it "will be reviewing [its] compliance protocols and introducing ways in which [it] can effectively test not only for emissions performance but also for the potential presence of defeat devices," according to a statement provided to The Detroit News.
