Pure black BMW i8 hydrogen fuel cell prototype on the track

Largely coated in matte black paint with just a few touches of dark blue contrast, the BMW hydrogen fuel cell-powered i8 prototype looks stealthy just sitting still. Now, that ninja-like styling is taking to the track in this video to prove that its performance doesn't come with much noise. The quiet hum of the tires and an odd whir from the rear are all that you hear coming. As this i8 prototype picks up speed around the circuit, the sounds that the drivetrain makes just get weirder. When moving slowly, you can pick out the usual whine that's expected from conventional electric vehicles. However at higher velocities, the coupe almost makes a noise like its constantly exhaling. Along with the recently unveiled BMW 5 Series Gran Turismo hydrogen-fueled concept, this sneaky looking i8 is part of BMW's technological push to become a greener automaker. The company is also prototyping a turbocharged engine with water injection and new plug-in hybrid powertrains. Although this low-slung coupe is by far the most attractive of that bunch. We might not be too far away from actually seeing this tech on sale on models bearing the Bavarian brand's roundel, either. Thanks to collaboration with Toyota, the company wants to have fuel cell components ready by 2020, and sales could start early in the decade. Hopefully all of the company's FCEVs look as menacingly great as this i8 by that time, though.

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:

In-demand BMW i8 deliveries start in June, and it's more efficient than we thought

Memo to Elon Musk: objects in the rear-view mirror may be closer than they appear. In this case, it's a couple of plug-in BMWs. And they represent the closest thing to a true competitor for Musk and the Tesla Motors electric vehicles. The German automaker re-confirmed that demand for its upcoming i8 plug-in hybrid will exceed the initial supply batch, though BMW didn't release any specific numbers, Reuters says. BMW will start production next month with deliveries commencing in June for the 362-horsepower i8. The news is consistent with a November estimate from BMW that indicated that the first year of i8s were essentially spoken for in advance. We learned in late January that the number of i3 battery-electric vehicles imported to the US won't meet demand during that vehicle's first year of sales either. Here's the thing: all these people were interested in the i8 when BMW said the car got the equivalent of 94 miles per gallon. Turns out, those calculations were a bit off. Reuters also notes that the new numbers show the i8 gets 112 MPGe. That's on the lenient European cycle, but if anyone was holding out for an i8 with triple-figure fuel economy, your time (to get on the waiting list) has come.Motley Fool proposed late last month that BMW is positioned to be Tesla's only real competition when it comes to high-performance plug-in vehicles. The reasoning was that the BMW plug-ins, like the Teslas, are being built from scratch and don't just have EV powertrains dropped into existing vehicle platforms. Whether or not the competition is truly a two-team race is something we're not sure is completely decided yet, but we know it'll be fun to watch unfold either way. Want proof? Check out Autoblog's enjoyable First Drive of the i8 here.
