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.

The 2018 Audi SQ5 looks mean and switches to turbo power

Audi's huge Q8 wasn't the only crossover introduced by the German automaker at this year's Detroit Auto Show. Right alongside it came the 2018 SQ5, the brand's high-performance midsize crossover. This newest version ditches the previous generation's supercharger in favor of a turbo for its 3.0-liter V6. The powertrain is similar to the one used in the latest S4 and S5. Horsepower remains unchanged compared to the last SQ5 at 354, but torque sees a healthy increase to 369 pound-feet, and it's available anywhere from 1,370 to 4,500 rpm. The car itself weighs about 77 pounds less, too. It's a combination that should make the SQ5 pretty entertaining off the line. Coupled to the turbo engine is an eight-speed automatic and standard all-wheel drive. Power delivery and handling can be enhanced with a Quattro sport rear differential that can shuffle power left and right to aid cornering. Audi says the torque vectoring system can send almost all rearward power to one wheel as necessary. The differential is available as part of the S sport package, which comes with other upgrades including air suspension. The suspension gives the crossover a lower ride height by default. Both height and firmness can be adjusted, and it offers an "offroad" position that raises the car for maximum ground clearance. Inside, the SQ5 comes with a sportier interior than its Q5 counterpart. It comes with prerequisites such as a flat-bottomed steering wheel and more-bolstered seats. Audi also provides a Bang & Olufsen sound system and standard Apple CarPlay and Android Auto. The cabin experience can be further augmented with Audi's Virtual Cockpit LCD instrument panel, as well as driving assists such as a variable-ratio steering rack and adaptive cruise control that can handle stop-and-go traffic from 0 to 40 mph. Audi will begin selling the new 2018 SQ5 here in spring of 2017. Pricing for it and the Q5 has not yet been released. Related Video:

24 Hours of Le Mans an on-and-off love affair

There was little usual about this year's 24 Hours of Le Mans - intermittent rain in the weeks before the race meant cars didn't get on track as much as they wanted, and intermittent rain during the race meant cars went off track a lot more than they wanted. The race started with a wet track, and one of the records broken because of the random downpours was the number of times the safety car led the field - 11 times this year - although the record of two hours and 53 minutes of lapping behind the safety car, set in 2011, was not eclipsed.
None of that served to dampen the action. With little more than an hour left in the race there were cars still only a few seconds apart fighting for position, leads still changing because of pit stops and everyone drafting anyone they could.
Things didn't go the usual way up front, either - well, not exactly...
