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 i3 called 'most revolutionary car' since Ford Model T

The Ultimate Driving Machine, or at least one of them, may also be the Ultimate Engineering Success. Consultant Munro & Associates, which specializes in automotive tear-down analysis, pretty much said as much when taking an under-the-skin look at the BMW i3 plug-in. In short, the firm liked what it saw. Presenting at Detroit's Plastic's in Automotive conference this week, Munro CEO Sandy Munro called BMW's first mast-produced plug-in model the most revolutionary car "since Henry Ford's Model T." The car earned big points for its substantial uses of materials that are both lightweight (key for any plug-in's range) and recyclable. BMW has touted these advantages all along. In late 2013, the German automaker went as far as saying its use of carbon fiber reinforced plastic (CFRP) would reduce customer costs related to both repair and insurance. The i3 went on sale in the US last May and, by the end of the year, moved more than 6,000 units here. It sold almost 17,800 The i3 last November also was named the Green Car of the Year at the Los Angeles Auto Show, beating out models such as the compressed-natural-gas-powered Chevrolet Impala B-Fuel and the Audi A3 TDI diesel. Munro made news earlier this week when it offered a free i3 for anyone who bought the master- or OEM-level version of the report, though the report isn't cheap and that offered disappeared once Munro made his presentation. Check out Munro & Associates' press release below. Munro Discusses Groundbreaking Technology Finds from BMW i3 Teardown at Plastics in Automotive Conference; Offers New BMW i3 for Purchasers of Master-level Report DETROIT, Jan. 14, 2015 /PRNewswire/ -- During today's Plastics in Automotive Conference in Detroit, Sandy Munro, CEO of Munro & Associates, Inc., discussed – for the first time publicly – his consulting firm's findings from its extensive deep-dive teardown, costing and benchmark study of the BMW i3 urban electric car. During his presentation, "Deconstructing the BMW i3: Groundbreaking Technology and the Composite Car," Munro discussed the carbon fiber life module, polymer components, recyclability and safety of what he considers to be "the most revolutionary car in terms of creative engineering and manufacturing since Henry Ford's Model T." During the presentation, Munro focused on four crucial aspects of the BMW i3: the manufacturing of its carbon fiber life module; its polymer components; recyclability; and safety.

Thermal imagery of BMW M4 DTM pit stop is red hot

A pit stop is a pit stop, right? The race car pulls in, the crew changes the tires, pumps in some fuel, maybe swaps out a busted body panel or squeegees the windshield, and off it goes for another heat. Only pit stops have become the focus of news lately for a number of reasons, whether it's because of mishaps (like the ones that prompted F1 to ban mid-race refueling), new time records (due largely to said ban) or interesting new ways to film the fast-paced action.
A few weeks ago we brought you footage of an IndyCar pit stop filmed from multiple angles courtesy of Google Glass. Now BMW has released a brief clip of one of its M4 DTM racers coming in for fresh rubber, all filmed by infrared camera. Its the kind of technology BMW uses to help optimize its German touring cars for competition, and now the Bavarian outfit has released some footage for fans to enjoy.
The resulting thermal imagery gives you an idea of how hot the car runs (and where the heat is emanating from), how warm they get the fresh rubber before they get it onto the car, and what kind of temperatures the pit crew is subjected to. Look closely enough in the 25-second video below and you'll even see the heat sputtering out of the exhaust pipes as the M4 downshifts into its pit box. (Just don't try adjusting your speakers, the clip is without audio.)
