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 planning to stretch i3 into i5 family hauler?

If you're sweet on the new BMW i3 but wish it had more space to carry people and stuff, we've got good news for you. According to Autocar, BMW is planning on stretching the platform that underpins the i3 to create a new model, expected to be called i5.
The stretch job would add an extra four inches of legroom in the back and another six inches of rear overhang to the benefit of cargo space. The result would create a vehicle longer than the current Mini Countryman - although the next Countryman is likely to be even larger. As Autocar points out, the process of extending the i3's composte passenger cell likely wouldn't be as difficult or cost-intensive as lengthening a conventional metal chassis, although the rear doors would need to be re-engineered.
Whether the resulting vehicle would more closely resemble a hatchback, wagon, minivan or something in between remains to be seen, however BMW is said to have already registered the nameplates i1 through i8, signalling that the possibility is at least there to add more members to its new EV family.

2016 BMW X5 xDrive40e Review [w/video]

BMW is no stranger to electrification. The company put the world on notice with the launch of its innovative i sub-brand. But the lessons learned from the i3 and i8 aren't limited to these small-volume cars. The more mainstream X5 xDrive40e impresses with lessons learned from i, all without compromising the SUV's character. The combination of a 2.0-liter, turbocharged four-cylinder engine with an electric motor is good for 308 overall horsepower and 302 pound-feet of torque. Sure, 240 hp and 260 lb-ft come from the four-cylinder engine alone, but the electric motor – integrated within the ZF eight-speed automatic transmission's housing – chips in a maximum of 111 hp and 184 lb-ft of torque. The 9.2-kilowatt-hour lithium-ion battery can sock away enough electricity to drive up to 14 miles on a single charge and will recharge at your average 110-volt socket in about seven hours. Of course, the battery pack and electric motor are a big weight penalty. At 5,220 pounds, the xDrive40e is 430 pounds heavier than the standard xDrive35i. Still, the gas-electric powertrain hustles this husky X5 40e to 60 miles per hour in just 6.5 seconds, less than half a second slower than the 35i. The stopwatch figures are complemented by the best fuel economy of any gas-powered X5, at 56 miles per gallon equivalent and 24 mpg combined. Only the diesel X5 xDrive35d is more efficient, at 27 mpg. But achieving top fuel economy in the 40e isn't as simple as going easy on the throttle. Perhaps more than any vehicle we've tested recently, understanding how all the X5's systems work together is crucial to eking out the most mpgs. The xDrive40e's Drive Dynamics Control will be familiar to anyone that's driven a recent BMW. Eco Pro, Comfort (the default mode), and Sport make the same adjustments to the throttle response, steering weight, and dynamic damper firmness as they do in a standard X5. But in the xDrive40e, they also impact the way energy is recaptured. Comfort/Save offers the best blend of fuel efficiency while achieving maximum energy recapture. Sport mode's aggressive energy recovery is the fastest way to recharge the battery on the go. When it's working, there's a sensation similar to gently stepping on the brakes, though you actually aren't doing anything – this is a familiar experience to the way most EVs use regenerative braking. Comfort mode reduces this effect, and in turn how much energy is recaptured.
