Mercedes could make EV batteries with Audi, BMW

It's not a big leap from digital maps to batteries, it turns out.The head of Mercedes-Benz parent Daimler said recently that he envisions his company working together with German automotive competitors BMW and Volkswagen to further accelerate electric-vehicle battery technology. The three automakers recently worked together to enhance their in-car maps systems. Daimler CEO Dieter Zetsche talked about "commonalities" between automakers, not the least of which is the need for all of them to achieve increasingly stringent fuel-economy requirements in the European Union, at the Frankfurt Auto Show last week, according to Reuters. While these companies have made their own inroads as far as plug-in vehicles go, they are all behind the Renault-Nissan Alliance when it comes to public deployment of electric vehicles. This summer, Daimler, Audi and BMW hooked up to acquire the Nokia Here digital-mapping service for about $2.8 billion. The triad of automakers beat out companies such as Apple and Uber to buy the entity, which was founded in 1986 as Navteq. Nokia bought the company in 2007. The acquisition makes sense as the automakers work on improving their products with features like cloud-based data to warn drivers of icy roads and traffic jams. The technology will likely also eventually be used in autonomous vehicles. Automakers working together for a common goal of improved technology is nothing new, of course. General Motors and Honda agreed in 2013 to work together to accelerate hydrogen fuel-cell drivetrain development. Earlier that same year, Daimler said it would work with Ford and Nissan in a separate collaboration to speed up the development of hydrogen fuel-cell technology. Related Video:

2017 Audi S4 switches to turbo power, loses manual

If you dig the understated look of the 2017 Audi A4 but crave more power, then check out the latest S4. The new sport sedan sticks with a V6 but ditches the supercharger in favor of turbocharging to now produce estimated US figures of 354 horsepower and 369 pound-feet of torque. If there's one downside to the upgrade, it's that Audi only plans to offer the mill with an eight-speed Tiptronic automatic gearbox. The 2017 S4 is now quicker than before. The run to 62 miles per hour takes just 4.7 seconds, versus 4.9 seconds for the current sedan to reach 60 mph. The top speed remains at an electronically limited 155 mph, but fuel economy is claimed to be improved with a rating of 31.8 miles per gallon on the European testing cycle. All S4s come with Audi's venerable Quattro all-wheel drive, and it generally operates with a 40:60 front-rear power split. As conditions change, a maximum of 70 percent of the grunt can go to the front or 85 percent to the rear. Handling is also aided by a tweaked suspension that sits 0.9-inches lower than the A4. Beyond the different badges, the latest S4 doesn't visually advertise its prowess. LED lighting is standard, and quad exhausts rest in a new rear bumper with a subtle diffuser. The side mirror housings also get some aluminum-look trim. The interior layout echoes the A4 but with sport seats and a mix of Nappa leather and Alcantara upholstery. Audi's digital instrument cluster is optional and includes an exclusive sport screen among the three views. The new S4 goes on sale in 2016 as a 2017 model. In addition to the lack of a manual, there's no intention of offering the S4 Avant in the US. Sporty and high-tech: the new Audi S4 and S4 Avant September 15, 2015 | FRANKFURT/INGOLSTADT, Germany Audi launches the new S4 and S4 Avant at the IAA in Frankfurt am Main. The top models from the A4 series are ahead of the competition – with intelligent lightweight design, powerful engines, an extensive package of the latest technologies, and 260 kW (354 hp), 0 to 100 km/h (0 to 62 mph) in 4.7 seconds. (The all-new A4 and S4 are expected to go on sale in the U.S. market in 2016. The Avant is not planned for the U.S. market.) "At Audi, we have more than 20 years of expertise in developing our sporty S models," says Professor Dr. Ulrich Hackenberg, Member of the Audi Board of Management for Technical Development.

Audi pits S3 against Ur-Quattro on gravel

If you had to pick a winner between the latest Audi S3 and the original Audi Sport Quattro, which would it be? Both hot hatches pack around 300 horsepower and all-wheel drive, but they're separated by a good thirty years of development.
To find out, Audi took both to the old rally circuit in San Remo. Behind the wheel of the Ur-Quattro they put none other than The Stig himself - no, not the Top Gear test bot, but Stig Blomqvist, the Swedish former rally driver who drove the Quattro to the World Rally Championship in the mid-80s. In the S3 they put someone named Hermann Müller, who as best we can tell was one of Auto Union's original Silver Arrow drivers - but he died in 1975, so it's probably the guy who writes for the Audi magazine. Regardless, the contest was pretty close, so it's worth checking out in the 2:26 video clip below.
