Can the government mechanically force you to wear your seatbelt? [w/poll]

The National Highway Traffic Administration is considering the use of ignition interlocks in vehicles that would require the seatbelts of occupied seats to be fastened in order to drive the car, Automotive News reports, four decades after Congress moved to prevent manufacturers from installing them in cars sold in the US market. Following a transportation bill passed last year that lift some of the restrictions on seatbelt interlocks, automakers such as BMW are considering the benefits of using them in future cars. Now, before you go crying about your lost freedom, keep reading.
BMW said in an October 2012 petition that the use of seatbelt interlocks would allow the company to make lighter and more spacious vehicles, if the devices could be used in lieu of unbelted crash tests. The crash test has required the addition of bulky safety features, such as knee bolsters, that aren't as necessary when occupants are buckled up, especially when considering the dizzyng list of safety features that come standard on today's cars. Europe, which has a higher rate of seatbelt use than in the US, doesn't perform unbelted crash tests on cars sold there.

BMW M4 Concept leaked ahead of Monterey debut

Last month, we heard that BMW might be bringing a concept previewing its next M4 sports coupe to this year's Monterey festivities. Well, thanks to the folks at USA Today, we have absolute confirmation of this by way of some leaked images. And goodness, she's certainly a looker.
While a few of us still find some of the 4 Series' design to be a bit awkward, it's hard to not immediately warm up to the aggressive bits of this hotter M4 concept. It certainly looks the business of a proper sports car, and a worthy successor to the M3 coupe. Of course, a lot of this will likely be toned down for the production version, which we'll likely be seeing at the 2014 Detroit Auto Show in January, along with its four-door M3 kin.
The official M4 Concept details will be revealed later tonight, but for now, have a look at a few shots of the golden show car in our gallery of leaked shots, above.

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?
