The automotive world's migration to hybrid vehicles won't slow down in 2012. Ford Motor Co. will roll out its C-Max hybrid and C-Max Energi plug-in hybrid, while Toyota unveils its Prius PHV. But the show-stealer could be the "micro-hybrid," or "start-stop" car. The micro-hybrid, which has been quietly waiting in the wings for years, will make its biggest move yet in the coming year. Ford, Chevy, Buick, Kia, and others will roll out the technology in 2012, joining a handful of models from Fiat, Volvo, and Alfa Romeo that already have it. At its most rudimentary level, start-stop will enable vehicles to turn off their engines while waiting at stop lights, stop signs, or in heavy traffic. Soon, however, it will go beyond that level, enabling engines to shut down while a vehicle is coasting, in some cases as fast as 75mph. Experts say that the technology will be employed on every new car by 2025, making it impossible for even the most dedicated gasoline burners to avoid it. Bosch's start-stop starters, shown, can reduce a vehicle's fuel consumption by 5 percent.

benmlee2, you said "The only place where weight comes into play is which party gets hurt more." Only? For me, that's the top reason not to have a smaller car. But I wasn't talking about driving a Hummer, I meant more like the Nissan Sentra-sized compact I drive today. OTOH, I was driving one of those years back when a semi driver tried to run me off the road, who knows why. It's happened more than once. That aggressive behavior you describe has been going on for decades, though it does go in cycles.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
