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 i8 to go full-electric after facelift

According to Autocar, BMW has plans to turn the i8 sports car from a hybrid to a fully electric vehicle. The carbon fiber structure would be modified with a wider center tunnel to house a sizable battery. Despite this, there would be no weight gain to the i8; the current version weighs in at 3,274 lbs. The electric prototype would have three BMW-developed brushless electric motors, two of them powering the rear wheels and one of them taking care of the front wheels. As the 1.5-liter gasoline engine would be shelved, there would be ample space for the two rear-mounted motors. Currently, the i8 produces 357 horsepower all told, but the electric motors in the prototype are said to produce up to 268 horsepower – each. The electric prototype is to be based on the architecture of a hydrogen prototype, which manages 242 horsepower in total. The information relayed on to Autocar comes from a source close to BMW's development boss, Klaus Frohlich. The facelifted version of the i8 should arrive next year, with awaited improvements like a new 26Ah lithium ion battery – 6Ah up from the current version. There is also talk of a Qualcomm inductive charging system, and its 7.2kWh operating power is doubled from the current 3.6kWh plug-in setup. If the rumormill is to be believed, engine output in the facelifted version would be up ten percent, resulting in 390 horsepower.

BMW 1 Series GT spied in 7-seat trim

As BMW prepares to introduce its first-ever front-wheel drive car, the upcoming 1 Series GT, it looks like there will be at least two versions of the car. A conventional-looking hatchback was spotted testing late last year, but now we see an extended-length version in order to accommodate a third row of seats.
Judging by these spy shots, this 1 Series GT prototype has received an extended wheelbase, larger rear doors and more upright D-pillars compared to our previous spy shots (show in the gallery below) all with the aim of creating additional passenger and cargo space. Like the smaller 1 Series GT, this longer model would likely carry over the same powertrain options, which are expected to consist of three- and four-cylinder engines, a hybrid system and the choice of front- or all-wheel drive. The 1 Series GT could make its debut this fall at the Frankfurt Motor Show, but we might have to wait until next year to see the people mover.
