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.

NHTSA, IIHS, and 20 automakers to make auto braking standard by 2022

The National Highway Traffic Safety Administration, the Insurance Institute for Highway Safety and virtually every automaker in the US domestic market have announced a pact to make automatic emergency braking standard by 2022. Here's the full rundown of companies involved: BMW, Fiat Chrysler Automobiles, Ford, General Motors, Honda, Hyundai, Jaguar Land Rover, Kia, Mazda, Mercedes-Benz, Mitsubishi, Nissan, Subaru, Tesla, Toyota, Volkswagen, and Volvo (not to mention the brands that fall under each automaker's respective umbrella). Like we reported yesterday, AEB will be as ubiquitous in the future as traction and stability control are today. But the thing to note here is that this is not a governmental mandate. It's truly an agreement between automakers and the government, a fact that NHTSA claims will lead to widespread adoption three years sooner than a formal rule. That fact in itself should prevent up to 28,000 crashes and 12,000 injuries. The agreement will come into effect in two waves. For the majority of vehicles on the road – those with gross vehicle weights below 8,500 pounds – AEB will need to be standard equipment by September 1, 2022. Vehicles between 8,501 and 10,000 pounds will have an extra three years to offer AEB. "It's an exciting time for vehicle safety. By proactively making emergency braking systems standard equipment on their vehicles, these 20 automakers will help prevent thousands of crashes and save lives," said Secretary of Transportation Anthony Foxx said in an official statement. "It's a win for safety and a win for consumers." Read on for the official press release from NHTSA.

Automakers making the commitment are Audi, BMW, FCA US LLC, Ford, General Motors, Honda, Hyundai, Jaguar Land Rover, Kia, Maserati, Mazda, Mercedes-Benz, Mitsubishi Motors, Nissan, Porsche, Subaru, Tesla Motors Inc., Toyota, Volkswagen and Volvo Car USA.

12 new cars that will never go out of style

Some cars never go out of style. It’s rare, but it happens. They get old. They get depreciated. But they never stop looking cool.  Some might call them modern or instant classics. Within a few years theyÂ’re no longer the latest and greatest, no longer the flavor of the month, but they remain special. Eternally special. Timeless.  These cars arenÂ’t necessarily going to be worth a fortune someday. However, some may not depreciate as rapidly or as far as other models. But thatÂ’s not what weÂ’re talking about here. These are the cars that enthusiasts will always find desirable from the curbside. TheyÂ’re the cars you end up shopping on eBay late at night 10 years later because you canÂ’t get them out of your head. TheyÂ’re the cars that will forever excite you when you spot a clean one in traffic or in a parking lot.  There are plenty of recent examples over the past couple of decades that could count as instant design classics. But then we got to thinking, what 2021 models will be forever cool to stare at? Which new cars and trucks on sale today will we be shopping on eBay late at night in the 2030s? We kept supercars and other ultra-expensive cars off the list to keep things within the realm of attainability, and ended up with 12 total cars. Lexus LC WeÂ’re not applying a numerical ranking to any of the cars on this list, but if we were, the Lexus LC would be No. 1. There isnÂ’t another car design out there that can stir our emotions the way an LC can when itÂ’s just standing still. This car is a concept design come true in the most beautiful of ways, and itÂ’s a shoo-in winner for Concours events decades into the future. All of this heaping praise, and we havenÂ’t even gotten to the LC 500Â’s intoxicating 5.0-liter V8. It doesnÂ’t win drag races. It wonÂ’t be the fastest around the track against any similarly-priced competition. But none of that matters. ItÂ’s quite possibly the best car you can buy new, and that says it all when it comes to the LC. Chevrolet Corvette It might not be the stunner that the Lexus LC is, but the new C8 Corvette is and will always be a special vehicle. ItÂ’s the first mid-engine Corvette, which instantly cements it into an automotive hall of fame section of sorts. All of the performance stats and specs are there to back up its supercar-like looks, and it remains the best performance bargain on sale today.
