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 2017 Audi R8 Spyder starts at $176,350

Audi just revealed pricing info for the R8 Spyder, which will start at $176,350, about a year after revealing pricing information for the coupe ( which starts at $164,150 in base form; the Plus starts at $191,150). In case you haven't had your coffee yet, like-equipped base cars will span a $12,000 gulf. But the 2017 R8 Spyder costs about the same as the outgoing R8 Spyder V10 equipped with an automatic (which was at the time a very expensive option), so consider that minimal price inflation. The more interesting comparison is with its platform-mate, the Lamborghini Huracan. A drop-top version of the Italian supercar starts at $267,545 in similar AWD trim with a 5.2-liter V10. Now, it is true that the Huracan Spyder makes 602 horsepower, a 62 horsepower advantage over the standard R8 Spyder with the same engine (540 hp if you are bad at math). The Lambo also a tenth faster to 60 mph than the R8 Spyder, at 3.4 seconds. (The '17 R8 Spyder is itself a tenth quicker than its predecessor, so there's that.) But, the R8 V10 Plus makes 610 hp. We're waiting to hear back form Audi on pricing for that Spyder model. In the coupe, it's a $27,000 increase over the base R8 V10. That logic would peg an R8 Spyder V10 Plus at around $203,000, or $64k less than the Huracan. In either case, you're paying a lot for Lamborghini's unique styling and tuning, although it's hard to put a price on the specialness of driving a Lamborghini. The Huracan Spyder never for a moment lets you forget you're in something fast and Italian. That being said, both are legitimate supercars. The R8 Spyder was developed alongside its Italian cousin, and features an appropriately large amount of aluminum and carbon fiber materials in its construction. Of course, like its coupe counterpart, there's no manual available for the new R8 Spyder. That died with the previous generation. The good news, for fans of open-air driving, is that the roof mechanism only adds 97 lbs to the weight of the car, and Audi kept the electrohydraulics that actuate it as low as possible. If it's anything like the Coupe to drive, and you can be sure since it's an Audi there won't be much trade-off for the open roof, it'll have a dual personality that will accommodate both daily driving and occasional track use. Sounds like a deal, huh? Related Video: Audi Convertible Luxury Performance Supercars r8 spyder r8 huracan

2016 Mazda MX-5 Miata named World Car of the Year

Kicking off Day Two of the New York Auto Show, the World Car of the Year awards are finally being handed out. The overall winner is, as God himself intended, the Mazda MX-5 Miata. It beat the Audi A4 and the Mercedes-Benz GLC-Class. The unique thing about these awards are that they aren't limited to the US domestic market (that's why they're called the World Car of the Year awards). For example, nominees for the overall award included the Skoda Superb, Renault Kadjar, and Subaru Levorg. In the Performance category, the forbidden fruit was repped by the Honda Civic Type R. But both the Civic and the Mercedes-AMG C63 Coupe were beat out by a far more expensive competitor – the new Audi R8. The fourth-generation Toyota Prius and the second-generation Chevrolet Volt, were two of the big finalists for the World Green Car of the Year award. They both lost out, though, to the Mirai fuel-cell car. Yes, a hydrogen car beat out two of the world's premiere hybrids. The luxury race that was perhaps the hardest to predict. That's because each of the three finalists have received near universal acclaim. In the end, though, the BMW 7 Series beat out the Audi Q7 and Volvo XC90. Finally, we have the World Car Design of the Year, where the overall winner (MX-5) and the Mazda CX-3 faced off against the new Jaguar XE. While both the CX-3 and XE are handsome vehicles, the WCOTY committee realized the answer is always Miata, and awarded Mazda's iconic roadster another 2016 award.

MAZDA MX-5 - 2016 WORLD CAR OF THE YEAR NEW YORK – March 24, 2016 - For Immediate Release The Road to World Car journey ended today with the declaration of the MAZDA MX-5 as the 2016 World Car of the Year. The winner was announced during a press conference hosted by the New York International Auto Show, Bridgestone Corporation and Autoneum. 2016 marks the 10th anniversary of the partnership between World Car and the New York show, and the third consecutive year that the World Car Awards have retained their ranking as the number one automotive awards program in the world in terms of media reach. Mazda Motor Corporation is no stranger to the World Car Awards program – now in its 12th year. The Mazda2/Mazda Demio was the 2008 World Car of the Year. While the Mazda3 (2014), Mazda6 (2013) and Mazda MX-5 have all earned "Top Three in the World" status as voted by our 70 plus international automotive journalists that make up the jury.
