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 with 500+ horsepower in the cards?

While BMW makes plenty of machinery to keep enthusiasts interested, its most enticing models are often based on more ordinary ones. That's what made the arrival of the i8 so captivating, emerging as the first stand-alone BMW sports coupe since the M1. But if its dual purpose - trying its best to both embrace the earth and traverse it rapidly - somehow left you disappointed, the next development could prove to fix that.
According to Automobile, BMW is working on a more potent i8S model. The hardcore version of the hybrid sports car would offer more power and a stiffened chassis to make it that much more aggressive. The Bavarian automaker is reportedly still evaluating two potential powertrain options: The first would pair a 2.0-liter twin-turbo four-cylinder good for 320 horsepower to an electric motor with another 204 hp. The second would use a 3.0-liter straight six with 480 hp and an electric motor with 109 hp. Both would be mated to a nine-speed dual-clutch transmission and an integrated starter motor packing an extra 27 hp.
Either way, we'd be looking at a combined output well in excess of 500 horsepower - far more than the existing i8's 228-hp turbo three and 129-hp electric motor - dropping the 0-62 time down from 4.1 seconds to an estimated 3.5. Couple that to a more advanced carbon chassis, wider tires and other goodies, and the i8 would be transformed into a far more capable performance machine than it already is.

Recharge Wrap-up: Derailing Malaysia's B10 plans, Tesla and Solyndra

Tesla Motors will lease the Solyndra building near its Fremont, California factory. The manufacturing facility is more than 500,000 square feet, but the cost of the lease and the production capacity remain undisclosed. The lease of the building, "located conveniently down the road from the Tesla Factory, gives us the space to expand our manufacturing and build more engineering labs as we build up production," says a Tesla spokesperson. The added manufacturing space will help Tesla meet its production goals for the upcoming Model X electric SUV. Trip Chowdhry, senior analyst at Global Research Equities, says that shifting some engineering duties from the Deer Creek facility to the new one could help solve current parking shortages, as well.

Malaysia recently announced that it would use crude palm oil to make the B10 blend that would be required to be sold beginning in October, up from the current B7 mandate. "In our tests with B10 biodiesel worldwide, we have found technical challenges," says BMW Group Malaysia Managing Director and CEO Alan Harris, such as the fatty acid methyl ester in palm oil thinning motor oil. Mercedes-Benz also urges reconsideration of B10. The Malaysia Automotive Institute says it will include representatives from the auto industry in talks with the Malaysian Palm Oil Board.

In 2009, ethanol suffered a price drop that forced Pacific Ethanol to decrease production and declare bankruptcy for four of its plants. Now its base extends from the West Coast to the Midwest, as Aventine Energy Holdings has four plants in Illinois and Nebraska. The merger more than doubles Pacific Ethanol's production capacity, making it the fifth-largest ethanol producer in the US. Read more from The Sacramento Bee.
