BMW mulled ten, eight, and six-cylinder engines for i8 before going hybrid

There's little doubt that the 2015 BMW i8 is one of the most radical and groundbreaking performance cars this industry has seen in a long time. From its unique carbon-intensive construction to its 1.5-liter, three-cylinder and electric motor plug-in powertrain to its concept-car appearance, the flagbearer for BMW's new i venture challenges the very notion of what it takes to be a supercar.
Yet apparently the i8 almost didn't do that at all. Yes, it probably still would've had innovative assembly techniques, serious performance and come-hither bodywork, but according to a new report in the Telegraaf, it was very nearly a much more conventional beast, drawing its power from a V10 engine. According to the report, that line of development never got much beyond the drawing board, but BMW engineers then shifted their focus to both V8 and six-cylinder motivation, going so far as to build prototype cars. The higher cylinder-count engines were eventually dropped altogether after BMW decided to turn the i8 into a hybrid, with the six-cylinder reportedly nixed due to heat management and weight issues. In the end, of course, BMW went with the PHEV powertrain that offers a total system output of 362 horsepower and 420 pound-feet of torque - plenty of thrust for this lightweight, all-wheel drive coupe while still enabling an incredible 94 miles to the gallon on the EU cycle. Regardless of how it turned out, it's still fascinating to think that BMW didn't have a much firmer conceptual idea of what it was after when it started the i8's development.
Here at Autoblog, we're genuinely thrilled about this new generation of greener hybrid super- and hypercars, a movement spearheaded by the i8, Porsche 918 Spyder, Ferrari LaFerrari and McLaren P1. But even so, our inner-gearheads can't help but wonder what might have been had BMW pursued a more conventional i8, either in place of, or in addition to, the car they did build. What do you think?

History of BMW touring cars looks splendid in Adrenalin trailer

More high-quality documentaries about the history of motorsports are always welcome. When thinking about racing, we generally focus on moving forward to go a little faster or shave a tenth of a second off a lap. There's not much time to look backward. It's too bad, because there are so many fantastic stories from the sport's history. Thankfully, an upcoming doc is taking on the challenge of telling some of these tales, and it looks like a movie not to miss, especially for BMW fans.
Adrenalin - The BMW Touring Car Story mixes high-quality, vintage footage with new interviews from many of the drivers of these machines to craft what looks like a fantastic experience. Covering the period from the '60s to the modern DTM era, just the trailer shows racing from the 2002, 3.0 CSL and of course the E30 chassis M3 of the '80s. You also get to hear from legends behind the wheel like Hans-Joachim Stuck, Johnny Cecotto and Joachim Winkelhock telling their stories.
Adrenalin comes out in November on DVD, Blu-Ray and on-demand. Check out its trailer above for a taste at what it's aiming for. The documentary definitely looks like one to watch.

BMW i5 could get Toyota-sourced hydrogen power

It's starting to feel like the automotive landscape is right on the cusp of a boom in hydrogen-fueled vehicles. After all, the Toyota FCV is nearly ready, Volkswagen is readying a fuel cell concept for this week's Los Angeles Auto Show and Hyundai already sells its Tucson Fuel Cell. The next big name to add to that list might be BMW, as the company's co-development deal with Toyota starts to bear fruit.
According to Autocar, BMW may use a version of the fuel cell system from the Toyota FCV in the future i5. As part of its eco-oriented i sub-brand, the i5 is expected to be a stretched version of the i3 (pictured above) with extra rear legroom and cargo space. It's unclear at the moment whether a battery-powered pure electric powertrain will also be available. If accurate, then the rumor could give the Bavarian brand a counterattack against Mercedes-Benz' planned fuel cell vehicle in 2017.
BMW and Toyota first signed the memorandum of understanding to co-develop fuel cells, lightweight technology and a sports car back in 2012, and they made the arrangement official in late 2013. So far, few details on the progress of the work have been disclosed, but the performance model has been rumored to use a front-engine, all-wheel drive layout with supercapacitors.
