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?

2015 BMW X6 stays the course with more power, RWD model

What would this world be without the BMW X6? Oh, sure, the whole coupe-crossover design trend surely would have started somewhere, but BMW was the first, launching its odd duck back in 2008. Much as we like to harp on the X6 (for being less functional and more expensive than the X5 on which it's based), people around the world sure do seem to like the thing, BMW having sold some 250,000 examples since the CUV's birth. And as you first saw thanks to leaked images this morning, the second-generation X6 has just arrived.
The shape is familiar, as are specific styling elements like the larger headlamps (now available with a full-LED treatment) and taillamps, mimicking those found on the X5. Two trims are available - xLine and M Sport - the former taking a more subdued approach, while the latter uses the traditionally bulgy and aggressive M-badged kit, with larger air intakes and matte aluminum grille bars. All X6s come standard with 19-inch wheels, and 20s are optional.
Regardless of trim, BMW will now offer the X6 in three guises here in the United States: sDrive35i, xDrive35i and xDrive50i. Dissecting the nomenclature, that means the first two models will be powered by BMW's 3.0-liter turbocharged inline-six, good for 300 horsepower and 300 pound-feet of torque. The sDrive X6 uses rear-wheel drive, while the xDrive, of course, uses all-wheel drive. Moving up, the xDrive50i uses the same twin-turbo 4.4-liter V8 as its predecessor, though power has been increased to 450 hp and 480 lb-ft. All X6 models are fitted with an eight-speed automatic transmission, and BMW says that the new powertrains are more efficient than before, though official fuel economy numbers have not yet been released.

BMW looking to fix i3 acceleration problem uncovered by Consumer Reports

The BMW i3 has been hailed in some quarters as the future of electric mobility, what with its innovative carbon-fiber-reinforced plastic body and commitment to sustainable materials wherever possible. The modernist little hatch is even available with a 650cc two-cylinder gas engine with 34 horsepower to act as a range-extender for those who want it. However, that optional engine might have a drawback - at least for the moment.
Consumer Reports brought the problem to light when one of its drivers was behind the wheel of an i3 using the range-extender. When the driver attempted to pass another vehicle on a rolling, two-lane road, the BMW suddenly had no power to accelerate - a scary situation. CR started examining the car and found something pretty shocking: After driving at a constant speed for a while without any regenerative braking in range-extended mode, acceleration to 60 miles per hour plummeted from about 9 seconds normally to a staggering 27 to 40 seconds in their testing.
A BMW spokesperson told CR that it knows about the problem and has a fix coming next spring that also works on current models. The upgrade includes a state of charge indicator, a warning about loss of power and uses the car's navigation to boost the battery before driving on rolling terrain. It is not clear if the severe power deficiency will also eventually result in a recall.
