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?

BMW bringing 9 Series concept to Beijing

It appears that BMW is ready to take another step upmarket with a new concept flagship luxury sedan at the Beijing Motor Show at the end of April. The showcar is said to preview the company's rumored 9 Series, a sedan that would be positioned against top trims of the Mercedes-Benz S-Class, like the rumored S600 Maybach.
According to Automotive News Europe, the concept sedan wears styling language adapted from the curvaceous BMW Pininfarina Gran Lusso Coupe (pictured above) shown at the 2013 Villa d'Este Concours d'Elegance in May. It rides on BMW's new, modular platform - codenamed G11 - for the company's largest cars, an architecture also expected to be shared with the next 7 Series and future Rolls-Royce vehicles. It's rumored to bring the weight of the 7 closer to the 5 Series, which would be several hundred pounds lighter when comparing the base models of both current vehicles. We spotted the next-gen 7 Series testing over a year ago, and both it and the 9 Series are expected to go on sale in 2016.
Unfortunately, at the moment there is no official information about the concept. "We don't have any official news yet on anything in Beijing," Julian Arguelles, BMW USA spokesperson, tells Autoblog. However, it's heartening to think that BMW might be adapting the gorgeous shape of the Gran Lusso for production.

Check out the trick way you access the tire valve on this BMW Alpina B6

The wheels are one of the first things you notice when checking out the 2015 BMW Alpina B6 xDrive Gran Coupe. The 20-inch aluminum alloy rollers have 21 spokes that spray out from their hubs, creating one of Alpina's signature design features. But there's also plenty of function to go along with the stylistic form of this hotted-up BMW 6 Series Gran Coupe.
By rotating the Alpina roundel and unlocking the center hub, you gain access to the tire valve and bolts, which are hidden inside. They're literally kept under lock and key, and they protect your Alpina's wheels from the elements and theft. This unique center-fill system employing a hollow spoke isn't a new setup for the favored BMW tuner, but since Autoblog had one in our offices this week, we thought we'd take the opportunity to show the unique mechanism in case you haven't seen it before. Check it out in our brief video below.
