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.

Alpina bringing new B4 Bi-Turbo Cabrio to Geneva

Interested in picking up a new BMW 4 Series with a turbo six? You've got options: you can get the 435i with 300 horsepower or spring for the M4 with 425 hp. But if it's the convertible model you want, we're afraid you'll be limited to the latter as the M division can't help you (at least not for the time being). But that's where Alpina comes in.
The aftermarket tuner closely associated with BMW offers the B4 Bi-Turbo (at least in Europe) with that same 3.0-liter twin-turbo inline-six massaged up to 410 horsepower that starts to pose a threat to the M4. What's more is that the Alpina's 442 pound-feet of torque eclipses the M4's 406 lb-ft, to say nothing of the 435i's 300.
Best of all, Alpina just confirmed via Facebook that it'll offer the B4 in convertible form, bringing the resulting BMW Alpina B4 Bi-Turbo Cabrio to the Geneva Motor Show. We'd expect the weight penalty to knock it slightly off the coupe's quoted 4.1-second 0-60 time, but not by much. If only BMW were to bring this one Stateside like it does with the B7 sedan.

2015 BMW i8: Autoblog Technology of the Year finalist

Traditionally, nominations for the Autoblog Technology of the Year award are earned for specific developments - a new-think powertrain, a uniquely developed material, a groundbreaking smartphone app, or what have you. In the case of BMW's marvelous i8, it so bristles with novel applied sciences and fresh features that we broke with tradition and nominated the entire car.
We just couldn't help ourselves. Oh, we could've focused on the i8's carbon-fiber monocoque, or its well-resolved plug-in-hybrid powertrain that incorporates a tiny 1.5-liter three-cylinder engine and an electric motor, or its seamless through-the-road all-wheel drive. This is a car that will even have frickin' laser beams for headlights - at least it will for our friends in Europe (and it will in the US, should our legislators ever catch up).
