BMW shows off 245-hp, hydrogen-powered 5 Series GT

With BMW's Innovation Days 2015 underway, the German luxury brand is showing off its latest piece of hydrogen-fuel-cell technology. Based in a 5 Series Gran Turismo, the system Í– co-developed with Toyota – promises to deliver on the promise of zero-emissions motoring, without the lengthy recharge times associated with plug-in electric vehicles. At the heart of BMW's latest FCV prototype is a new electric motor derived from the i sub-brand. It produces the equivalent of 245 horsepower, making it roughly comparable in output to the brand's latest 2.0-liter, turbocharged, four-cylinder gas engines. It draws its fuel from a hydrogen fuel tank that sits between the axles. The BMW-patented storage system can hold enough compressed hydrogen to take the hunchbacked 5 Series 300 miles before refueling. BMW and Toyota first inked their FCV partnership back in 2013, with the goal of having "an initial group of approved components ready by 2020," and sales beginning at some point in the next decade. While Toyota has been touting its successes with hydrogen in the form of the new Mirai, this 5 Series marks the first time since the agreement was signed that the German company rolled out one of its hydrogen-powered cars to the public. Check out the 5 Series GT fuel-cell vehicle in the gallery up top, and then scroll down for the official press release from BMW. Long range, short refuelling times, zero emissions: Hydrogen fuel cell drive system points the way to the future of BMW eDrive technology. As part of its research and predevelopment work in the area of drive technology, the BMW Group has focused on the use of hydrogen as an energy source for more than 30 years now. In 2006 the first luxury sedan for everyday use to be powered by a hydrogen combustion engine was unveiled – the BMW Hydrogen 7. And more than 15 years ago the BMW Group also began to direct its spotlight onto hydrogen fuel cell drive systems. A constant stream of significant advances – in terms of energy efficiency, performance capability and everyday practicality – have likewise been made with this technology, which converts hydrogen into power for an electric drive system, rather than burning it inside the engine. The results of the research and development activities in the field of hydrogen fuel cell drive systems will be presented in driving demonstrations for the first time during the BMW Group Innovation Days 2015.

2015 BMW M4 Convertible Quick Spin [w/video]

Quite a while ago, we ran a story where our editors disclosed their guilty pleasure cars. There, I admitted my love for the ultra-comfortable Acura RLX. But I have another automotive guilty pleasure, and it's the BMW M4 Convertible, and the droptop M3 that came before it, as well. Whether it's an E46, E93, or the new F83 M4 model, I just love the idea of a droptop M car. It kind of goes back to my Lexus RC F review, where I posit that most consumers buy a car like this solely for the image. To the point of this car, if you're opting for a convertible, you're boldly throwing out any pretense that you bought this car for its performance. It's a different and far grander indulgence than something like a droptop Ford Mustang, Chevrolet Camaro, or even a Corvette, and that's especially the case with the new M4, as I found out after a week at the wheel. Driving Notes Anyone that's listened to me on the Autoblog Podcast knows I've been none too kind about the state of BMW's turbocharged M cars. In effect, they're too easy to drive. In older models, the narrow power band meant you needed to always keep an eye on the tach, lest you fall into a weak zone. But because today's turbocharged M engines are so damn torquey, you can simply mash the throttle, regardless of engine speed or gear, and zoom forward. That's mostly the case here, although with a 7,500-rpm redline, the M4 at least maintains the illusion that you have to keep the revs up. Power delivery is fast and immediate, capable of catapulting the M4 towards the horizon at even half throttle. But more than the brutal power delivery, this latest M entertains with a strange but familiar singing voice. It's an almost feral, straight-six howl, particularly high in the rev range. But because of the single-scroll turbochargers and today's sound-tuning sorcery, the noise here is far richer and complex than what you'd get in a naturally aspirated M car, like the old E46. The turbos hiss and spit, and wide-open-throttle upshifts come with a cackling snap from the quad-tipped exhaust. Despite my belief that M cars' manual transmissions are generally pretty lousy these days, the M4's gearbox is far better than what you'll find in an M5. The clutch is more forgiving than in the larger sedan, too. With a broad catchpoint and a linear action, it feels natural and intuitive to work.

Recharge Wrap-up: Venturi to break electric world record, app shows where bike lanes are needed

Electric automaker Venturi hopes to post a new electric land speed record this week, despite Bonneville Speed Week being cancelled. The VBB-3, developed with Ohio State University, is powered by two 1,500-hp electric motors. If the salt flats are sufficiently dry, the team hopes to set a new electric world speed record of over 600 kilometers per hour (373 mph), and possibly 700 kph (435 mph). The Venturi BB-2.5 set a record of 495 kph (307 mph) in 2010. Read more at Electric Autosport, and keep abreast of Venturi's progress at its Twitter account. A new app is trying to fix Wiesbaden, Germany's bike problem. A bike organization named the city the worst in the world for cycling. In response, a local group developed an app that uses crowdsourced routes to suggest where bike lanes and paths should go. The app tracks users routes as they ride, and maps them to show where the city could benefit from improving its infrastructure. The app and its results have the attention of government officials, too. See the video below, or read more at Fast Company. BMW has delivered the first i8s at the Pebble Beach Concours d'Elegance in California. The first customers include Roger Penske, Rick Hendrick and Tony Fadell (founder and CEO of Nest). The lucky new owners were also treated to a gourmet meal from Chef Thomas Keller, who was also among those to receive the i8 at the event. As mentioned, BMW also auctioned off a special edition i8 at Pebble Beach for $825,000, considerably more than the car's base MSRP of $135,700. Read more in the press release from BMW, below. Uber's Berlin ban has been suspended by a local court. The city banned the car-hailing app for failing to meet passenger safety standards. The court will now decide whether to uphold the ban or toss it out. This was the second time this year that Uber had been deemed unlawful in Berlin. Uber continued to operate throughout its ban, despite threats of fines. If upheld, Uber could be fined $34,000 for picking up a passenger. Read more at The New York Times.
