New Audi Q5 refines original model's winning formula

The first Audi Q5 made a name for itself as a baby Q7, hitting a Goldilocks zone in the crossover segment and challenging BMW, Mercedes-Benz, and Lexus for supremacy in what would become one of the luxury market's most important segments. The Q5 is already Audi's best-selling vehicle globally, underscoring its importance to the German brand. Like its predecessor, the second-generation Q5 takes the Q7's looks and tech, then distills it into a smaller package. But unlike the Q7, the Q5 doesn't look quite so dowdy in its redesigned body. We'll attribute that to the smaller front and rear overhangs, which keep the Q5 looking like a crossover instead of a high-riding wagon. The face is mostly a carbon copy of the Q7's, with a prominent grille featuring a silver surround and flanked by a set of clean, stylish headlights. In back, the smaller Audi gets more expressive taillights that harken back to the first-generation model in their lighting signature. We aren't really sure what Audi was going for with its two-tier rear bumper, but it doesn't work and is inarguably the worst piece of an otherwise fashionable design. Aside from restyling the Q5's body, Audi managed to both expand it in every direction and trim nearly 200 pounds of body fat through a mix of "maximum tensile strength" steel and aluminum. Audi is also promising an impressive aerodynamics gain for the new body – the company's engineers slashed the coefficient of drag from 0.33 to 0.30. That should mean a quieter and more efficient drive. Like the Q7, the new Q5 benefits from Audi's push into advanced driver information systems. It gets the 12.3-inch TFT display, also known as Virtual Cockpit, on top of the 8.3-inch MMI display atop the center stack. MMI takes a page from Apple with its Personal Route Assist. Much as CarPlay will automatically display how long it takes you to get home, Audi's new system can study an owner's behavior and suggest the best route to a given spot, even when the navigation isn't active. While we're geeked about the new tech, the powertrain front is less newsy. The European press release lists one gas engine – a 252-horsepower 2.0-liter, turbocharged four-cylinder – and four TDI powertrains. Those latter engines are dead to the US, as Audi faces the backlash from parent company Volkswagen's diesel emissions scandal.

Hydrogen could deliver one fifth of world carbon cuts by 2050, industry says

BONN, Germany — Increasing the use of hydrogen in power, transport, heat and industry could deliver around one fifth of the total carbon emissions cuts needed to limit global warming to safe levels by mid-century, a report by the Hydrogen Council said on Monday. To encourage industries to use hydrogen, Toyota and Air Liquide helped set up the Hydrogen Council, a global lobby launched in January this year. Its 27 members include automakers Audi, BMW, Daimler, Honda and Hyundai, and energy firms such as Shell and Total. The council said using hydrogen for transport, energy generation, energy storage, industry, heat and power could cut annual carbon emissions by 6 billion tonnes by 2050. "This would ... contribute roughly 20 percent of the additional abatement required to limit global warming to two degrees Celsius," the council said in a report released on the sidelines of a U.N. climate conference in Bonn. To achieve a two-degree limit this century agreed by governments in Paris in 2015, the world must reduce energy-related carbon emissions by 60 percent by 2050. The report said one in 12 cars sold in California, Germany and Japan were expected to be powered by hydrogen by 2030. By 2050, hydrogen could power 400 million cars, 15 million to 20 million trucks, around 5 million buses, a quarter of passenger ships and a fifth of non-electrified train tracks, as well as some airplanes and freight ships. Achieving this shift in transport and other sectors would require investment of $280 billion by 2030, with about $110 billion to fund hydrogen output, $80 billion for storage, transport and distribution, and $70 billion to develop products. Fuel cell vehicles combine hydrogen and oxygen to produce electricity to power an electric motor, producing water as a byproduct. However, making hydrogen from fossil fuels, a common route, also produces some greenhouse gas emissions. So far the take-up of hydrogen vehicles is tiny and industry experts say their wider use is years away, with high purchase prices and a lack of refueling stations the major barriers. But some firms, such as miner Anglo American and carmaker Toyota, are pushing for fuel cell cars to play a role even with the rise of battery-powered electric vehicles (EVs). Woong-chul Yang, vice chairman of automotive research and development at Hyundai said EVs and hydrogen fuel cell cars were needed because EVs were better for city driving and fuel cell vehicles better for longer journeys.

Audi calls R18 E-Tron Quattro its 'most complex race car'

Technically speaking, Audi's R18 E-Tron Quattro is quite technical. The German automaker says the diesel-hybrid is the "most complex race car" it's ever created. And we'll take their word for it. The Audi, which pairs a V6 turbodiesel powering the rear wheels with two electric motors, is all about connectivity, giving the car's crew the opportunity to constantly monitor the vehicle while it's racing. The car sends in a host of data each lap to the crew's computers, and the vehicle's telemetry system constantly keeps tabs on things like hybrid energy levels, cockpit temperature and boost-pressure levels. In all, the amount of data parameters is more than 100 times greater than in 1989, when Audi first tested a race car equipped with automatic data transmission capabilities. Audi first released specs on the updated version of the R18 E-Tron Quattro late last year, trumpeting the vehicle's advantages in competing in the LMP1 class of the 2014 World Endurance Championship (WEC). Audi made the car a little narrower and a little taller and it complies with a new WEC regulation requiring the front end set off by a new wing. Take a look at Audi's most recent press release below. AUDI R18 E-TRON QUATTRO WITH COMPLEX ELECTRONIC ARCHITECTURE • Telemetry connection between race car and pit lane • Permanent acquisition of far more than 1,000 parameters • Various electronic control units interlinked by a multitude of CAN Bus systems Ingolstadt, May 5, 2014 – The Audi R18 e-tron quattro is the most complex race car created in Ingolstadt and Neckarsulm to date. This not only applies to the mechanics. The electronics of the most recent LMP1 race car with the four rings is more sophisticated than ever before. The age of electronic data transmission from the race car on track began for Audi in 1989. At that time, an Audi 90 quattro in the IMSA GTO series radioed eight parameters to the garage where engine speeds and a few pressures and temperatures were plotted on printouts – a tiny step from today's perspective, but one that provided important insights at the time. Today, an Audi R18 e-tron quattro on more than a thousand channels, in cycles that in some cases only amount to milliseconds, generates data of crucial importance to a staff of engineers at Audi Sport. At Le Mans, the engineers constantly monitor their race cars for 24 hours.
