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 builds its 2 millionth 1 Series on eve of new model's launch

Hard as it may be to believe, it's been over ten years since BMW launched the first 1 Series, taking the Bavarian automaker into more accessible territory for the first time. Later this month, the first examples of the new model will arrive at dealers, but before it does, the littlest BMW has another reason to celebrate as the 2 millionth unit has rolled off the line. The landmark example is a 120i five-door equipped with the M Sport package and painted in Estoril Blue, bound for a customer in Japan. The achievement is even more noteworthy when you consider that what started out as the 1 Series has since been split into two lines. The three- and five-door hatchbacks remain part of the 1 Series, while the coupe and convertible we get in the US that were once part of the 1 Series as well have since been spun off as the separate 2 Series. Production of the three-door takes place exclusively at BMW's plant in Regensburg, while the five-door is split between Regensburg and a second plant in Leipzig. Buyers are further able to specify between diesel and gasoline engines ranging from three cylinders all the way up to six.

Munich. 28 March 2015 sees the curtain raised on the market launch of the new BMW 1 Series. Fans of compact driving pleasure can look forward to an even more striking design, a further refined premium ambiance for the interior, engines that are extremely powerful and even more efficient, and innovative equipment features. Ahead of the launch, news filtered through from BMW Plant Regensburg of another reason to smile as the two-millionth BMW 1 Series rolled off the production line. The landmark car was built just a few days after the start of production for the new version of the compact model and is one of the first examples of the new BMW 1 Series range earmarked for export to Asia. The BMW 120i 5-door, painted in Estoril Blue metallic and equipped with an M Sport package, will be delivered to a customer in Japan. This production landmark at BMW Plant Regensburg represents another milestone in the international success story of the BMW 1 Series. In late summer 2014 the company celebrated the model series' tenth birthday.

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.
