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 details Concept X5 eDrive ahead of New York debut

Already weighing more than most other types of vehicles and with the space to accommodate the extra equipment, crossovers and SUVs arguably make for one of the more ideal platforms to transform into a hybrid. And there have been a handful of them - like the Audi Q5, Infiniti QX60/Nissan Pathfinder, Porsche Cayenne/Volkswagen Touareg, Lexus RX450h/Toyota Highlander and Cadillac Escalade/Chevy Tahoe/GMC Yukon - but by and large the majority of hybrids on the market are sedans and hatchbacks. BMW, however, looks poised to join the minority with the X5.
The Bavarian automaker showcased the X5 eDrive concept at Frankfurt last year, and as promised, has now revealed the followup it will present at the New York Auto Show in just a few days. The new Concept X5 eDrive, as BMW has now revealed, pairs a 2.0-liter turbo four good for 245 horsepower to a 95-hp electric motor to deliver a combined 340 horsepower. Its lithium-ion battery can power it for up to 20 miles and at speeds up to 75 miles per hour before the gasoline engine needs to kick in. All that without sacrificing the vehicle's utility, maintaining an almost perfectly flat loading floor with 40:20:40 split-folding rear seats, and without sacrificing much on performance, either: with a 0-62 time of seven seconds flat, the X5 eDrive concept is quicker off the line than the production X5 with the 2.5-liter turbodiesel and just a tenth off of the 3.0-liter turbodiesel.
With the full technical details now released (you can delve into it all in the press release below), the only question remains when BMW will actually put the X5 eDrive into production. Given its appearance in New York, though, we gather that whenever it does reach showrooms, it'll reach American ones as well.

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.
