Audi says new 48 volt micro-hybrid system improves fuel economy, paves way for electrification

Most cars use a 12-volt system to power their electrical components. But, with more and more electric bits and bobs being added to new vehicles, a dozen volts is looking a bit weak these days. In fact, Audi says that standard 12-volt systems are being stretched "to their very limits." Enter 48 volts. If used in a car that gets 40 mpg, that would translate to around 43.5 mpg. Audi is testing a supplemental 48-volt electric system in two prototype vehicles – modified mild-hybrid versions of the A6 TDI and the RS 5 TDI – in order to add in more electric technology (an electric compressor, for example, to improve acceleration) and "convenience systems for dynamic chassis control." Audi says it has more applications in the pipeline, but the overall gist is that the German automaker sees 48 volts as an "important building block in electrification strategy." As you can see in the picture above (click to enlarge), the RS 5 TDI concept uses a li-ion battery installed in the back of the car and an alternator to provide 48 volts when the engine is off. Audi says that the 48-volt system can save up to 0.4 liters of fuel per 100 kilometers. To put that into US numbers, if used in a car that gets 40 miles per gallon today, that would translate into a bump up to around 43.5 mpg. The Advanced Lead Acid Battery Consortium (ALABC) is also working on a 48-volt system to improve fuel economy and we've got a deep dive of Audi's electric turbocharger here. Even more powerful and efficient – the new 48-volt technology from Audi Important building block in electrification strategy More voltage and more power for new technologies Scalable platform concept suitable for wide-ranging uses Ingolstadt, August 25, 2014 – Audi is to upgrade part of its vehicle electrical system from twelve to 48 volts. The move represents another technical building block for facilitating the integration of new automotive technologies while increasing the power and efficiency of its cars. "We are using the full bandwidth of electrification in our drive principles strategy. Running part of the vehicle electrical system at 48 volts plays a central role in this," commented Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development at Audi. "It enables us to make more energy available.

2016 Audi SQ5 TDI Plus a quick sprinter with 35 mpg

Not only does Europe get cool diesel-powered models, but occasionally, some of those oil-burners are of the high-performance variety. Take the Volkswagen Golf GTD, Audi Q7 V12 TDI, and now this, the new Audi SQ5 TDI Plus. In this new form, the 3.0-liter, turbodiesel V6 is very nearly as powerful as the supercharged V6 available in the US-market SQ5, producing 340 horsepower. That's 27 more than stock, for those keeping track at home. In terms of torque, of course, the diesel-powered SQ5 just embarrasses the gas-powered CUV. Torque is up 37 pound-feet to a thumping 516 lb-ft. We'll go ahead and classify that as a lot. This extra output allows the SQ5 TDI Plus to hit 62 miles per hour in just 5.1 seconds, matching the supercharged model we have access to here in the US. The top speed, as with the gas-powered model, is limited at 155. Unlike North America's CUV, though, fuel economy is very impressive. European drivers can expect the equivalent of 35.6 miles per gallon, compared to just 24 mpg with the gas engine. We have a full set of images of the new SQ5 TDI Plus from the floor of the 2015 Frankfurt Motor Show. Scroll up and check them out.

In October, the new SQ5 TDI plus* will arrive at German dealerships with more power and driving pleasure and even more extensive equipment – with 250 kW (340 hp), sport differential and 21-inch wheels. Even in its basic version, the successful Audi SQ5 TDI* comes as an SUV with the performance of a sports car. The plus version has an even higher power output. The biturbo V6 TDI produces 250 kW (340 hp) from its three liters of displacement by way of increased injection pressure. This results in 20 kW/27 hp more power compared to the SQ5 TDI. Its peak torque is increased by 50 (36.9 lb-ft) to 700 Nm (516.3 lb-ft). The powerful diesel SUV accelerates from 0 to 100 km/h (62.1 mph) in just 5.1 seconds; the top speed is electronically governed to 250 km/h (155.3 mph). In the NECD cycle, it merely requires 6.6 liters of fuel per 100 kilometers (35.6 US mpg) with emission of 174 g CO2/km (280.0 g/mi).

Everybody's doing flying cars, so why aren't we soaring over traffic already?

"Where's my flying car?" has been the meme for impending technology that never materializes since before there were memes. And the trough of disillusionment for vehicles that can take to sky continues to nosedive, despite a nonstop fascination with flying cars and a recent rash of announcements about the technology, particularly from traditional automakers. Earlier this month, Toyota applied for an eye-popping patent for a flying car that has wheels with spring-loaded pop-out helicopter rotors. The patent filing says the wheels/rotors would be electrically powered, while in on-land mode the vehicle would have differential steering like tracked vehicles such as tanks and bulldozers. At an airshow in July, Aston Martin unveiled its Volante Vision Concept, an autonomous hybrid-electric vertical takeoff and landing (VTOL) vehicle it developed with Rolls-Royce. Aston says the Volante can fly at top speeds of around 200 mph and bills it as a luxury car for the skies. Audi used the Geneva Motor Show in March to unveil a flying car concept called the Pop.Up Next it developed with Airbus and Italdesign. If the Pop.Up Next, an electric and autonomous quadcopter/city car combo, gets stuck in traffic, an app can be used to summon an Airbus-developed drone to pick up the passenger compartment pod, leaving the chassis behind. Audi said that the Pop.Up Next is a "flexible on-demand concept that could open up mobility in the third dimension to people in cities." But Audi also acknowledged that at this point it has no plans to develop it. The cash-stoked, skies-the-limit Silicon Valley tech crowd is also bullish on flying cars. The startup Kitty Hawk that's backed by Google co-founder Larry Page announced in June that it's taking pre-orders for its single-seat electric Flyer that's powered by 10 propellers and is capable of vertical takeoffs and landings. The current version can only fly up to 20 mph and 10 feet in the air and has a flight time of just 12 to 20 minutes on a full charge. The Flyer is considered a recreational vehicle, so doesn't require a pilot's license. Uber says it plans to launch its more ambitious Elevate program and UberAIR service in 2023. "Uber customers will be able to push a button and get a flight on-demand with uberAIR in Dallas, Los Angeles and a third international market," Uber Elevate promises on its website.
