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:

This insane Barris-like custom car is a backyard BMW Z3 build

This is the second car made by Englishman Paul Bacon and it's called the Cosmotron, fashioned over 18 months in his backyard shed. Underneath that Jetsons bubble canopy and swinging-sixties body are the bones of a 1998 BMW Z3 with a 2.8-liter inline-six. Bacon stripped the roadster down, then built it back up using fiberglass laid over polystyrene foam, and leather hand-stitched by his wife. Bacon said he remembers how we were told that 21st-century cars would look like the Cosmotron, and since they don't, he had to fix the error. The list of 20th-century add-ons, however, is impressive, like the six SU carburetors topped off with department-store salt and pepper shakers, and the rear grille decorated with shiny plastic tops from moisturizer bottles. After driving the Cosmotron for two years, Bacon sold it to get ready for his third project. You can hear Bacon and the new buyer tell their stories in the video above.

Upgraded BMW 230i and M240i get more power, new badges

A few months ago, we got our hands on a report that claimed that BMW would ditch the 28i and 35i monikers for both the 2 and 3 Series. BMW already dropped the 335i designation in favor of the 340i badge, but the 328i is still hanging around. In the 2017 2 Series, the old badges are out. Meet the new 2017 230i and M240i, in both coupe and convertible flavors. If you're already confused about all the badge changes, here's the important part: the 2.0-liter inline-four and the 3.0-liter inline-six, both turbocharged, get more power than the engines in their 2016 counterparts. The 230i will get 248 horsepower and 258 lb-ft of torque, and be smoother than before. Those are increases of eight hp and three lb-ft of torque over the 2016 model. The M240i replaces the M235i. There's more power here, too: 335 hp and 369 lb-ft of torque, available from 1,520 rpm to 4,500 rpm. Those are increases of 15 hp and 39 lb-ft of torque, by the way. All-wheel-drive models are eight-speed automatic-only; a six-speed manual is a no-cost option on the 230i, and available on the M240i. These models will launch later this summer, and pricing will be available closer to that time. We reached out to a BMW spokesperson for a better understanding of what hardware and software changes are responsible for the increased output, but this information isn't yet available.
