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 to change model designations, further yet from actual displacement?

Once upon a time, you could look at the back of a trunk lid of a BMW and come up with a pretty fair idea of what sat under its hood. For example, a 320i was a 3 Series with a fuel-injected, 2.0-liter engine, a 328i was a 3 Series with a fuel-injected, 2.8-liter engine and a 328Ci was a two-door 3 Series with the same engine. Those were good days.
Today, though, that simplicity is dead and gone. A 328i now has a 2.0-liter engine, just like the 320i, while the simple "C" designation that was affixed to two-door models has been replaced with a "4," so we have a 428i and a 435i. It gets worse, though. A 550i uses a 4.4-liter, twin-turbocharged V8 (it should be a 544ti, although we'd be willing to hear an argument for "tti") and a 740i uses a 3.0-liter, turbocharged six-cylinder, which is the same engine found in a 535i. It's madness.
And, well, it's about to get madder, if a post on a BMW enthusiast forum is to be believed. According to f30post.com, we could see a shakeup in at least the 3 and 4 Series nomenclature, thanks to an impending refresh that will see the addition of new, turbocharged four- and six-cylinder engines, codenamed B48 and B58, respectively.

Xcar checks if BMW's i8 offers moves as electrifying as its looks

If you were to plot the general opinion about hybrids since their introduction among auto enthusiasts, the resulting graph would likely be shaped somewhat like a "V." In the beginning interest was high, simply due the novelty of these new powertrains, then the line would gradually fall as the models got the stereotype of being boring commuters. Today, though, things might be back on the upswing. Vehicles like the McLaren P1, Porsche 918 and BMW i8 are showing that a hybrid doesn't have to be synonymous for dull. In its latest video, Xcar Films aims to find out if BMW's electrified sports coupe actually earns the brand's old moniker as the ultimate driving machine.
While the focus here is on what the i8 is like behind the wheel, one of the main highlights for the viewer is the interesting ways that Xcar shoots the BMW. It's not necessarily a beautiful vehicle, but seeing it in motion reveals all sorts of little intricacies that still photos don't pick up. For example, our eye catches the flying buttresses and little crevices scooped out of the corners when we get a look at the rear. It's just a fun car to look at.
With its 1.5-liter, turbocharged, three-cylinder engine and electric motor, the i8 positions itself as the future of automotive performance. But its intriguing looks and cutting-edge use of carbon fiber would be wasted if the coupe didn't drive well. We won't spoil the final verdict, though, you'll have to watch the video above.
