The trend toward fuel efficiency isn't going away in 2012, or at any time in the foreseeable future. Because automakers are already on the hook to push their Corporate Average Fuel Efficiency (CAFE) to 35.5mpg by 2016, and 54.5mpg by 2025, they're going to be working hard on any feature that can eliminate even the smallest sip of gasoline. The most effective way to accomplish that is through the introduction of electric cars and hybrids of various types.
The innovation won't stop there, however. In 2012, we'll see the industry pushing the limits on a number of different fronts. Autonomous driving technologies will become more prominent. EV battery sizes will increase. Multicore processors will make a bigger move into the vehicle. And as that happens, engineers will fret about the electronic complexity that's taking over the automobile.

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.
I notice a change in driving attitude of SUV drivers base on events. Mid 2000-2001 when stock market crashed, SUV and truck drivers went berserk. Very aggressive as if to take out their frustration on the road. It was the only time in my driving career that I ever saw a lifted truck purposely try to run a small car off the road several times. Several other SUV did something similar at various times. It was just like in the movies. Up to this point, I have never seen such suicidal behavior on the road.
George Bush won the second term, they were aggressive in a different way. Stay out of their way. And if you merge in front of them too close, they will tail gate you for miles honking. Oct 2008 the second major stock market crash. SUV drivers were again aggressive. Not as much as the first crash of 2000 though.
After Obama won office, SUV drivers since have somewhat calmed down. Now with the high gas price and threat of higher EPA mileage, they have pretty much become normal drivers again. Is rare to see aggressive SUV drivers much now. Sociologist can do a research paper on this. I am probably more aware because I drove a 3 cylinder feather weight Chevy Sprint for a long time.
Is not the size of the car but the safety features that matter. F1 cars are light, and they are safe given the speed they travel at.
The only place where weight comes into play is which party gets hurt more. 4 ton vehicle against a 1 ton, and is simple physics. The person driving a 4 ton car to feel "safe" is really transfering the damage to the other party base on simple mass ratios. In the global picture, you are not making driving safer for everyone.
Is the my safety come at a price to your family attitude. Yes, everyone drives bigger cars so the other family will hurt more than you. Car were getting bigger and bigger until gas price squashed that game.
Good point, bonjengr. About ten years ago, a study showed that SUVs had a surprisingly high rate of accidents. The conclusion was that some SUV drivers felt that sense of fearlessness that you mentioned, and drove over-aggresively. That would seem to support the conclusion by many commenters here that it's not the car, it's the drivers. Bad drivers find myriad ways to drive poorly.
Good points, Dave. I have a friend who has used motorcycles as his primary mode of transportation for decades. His view is that motorcycles are the safest form of transportation up until the moment of impact. He was able to avoid accidents via the motorcycle's agility.
A few years back, I was in a deli, waiting for my lunch when a very elderly man rode up in his street/dirt motocycle. I asked him how long he had been riding and he estimated that he started before I was born. When asked if he was ever in an accident, he replied, "No - not ever, and do you know why? ...because I ride a very light and highly manueverable bike. I've been able to avoid almost certain accidents because of the bike's agility."
Now, take a look in any newspaper and notice that when teenage drivers are in serious accidents, they are almost always driving big SUVs that tip over very easily. Light cars generally brake in shorter distances, have quicker and more accurate steering, and of course, get better fuel mileage. I recall the commercial in which moms driving their kids to school got to the point where they were driving giant payloaders (to be more protected from the heavier and heavier vehicles being driven). Thankfully because of high gas prices, this is no longer the case. you should no longer feel that buying a large SUV is the only way to go to be protected in the event of an accident with an H2 Hummer.
Ann has an excellent point.I commute every day—approximately 40 miles one way so I average anywhere from 350 to 400 miles per week and its all interstate driving.I have seen several devastating wrecks over the past eight years most occurring in clear weather where drivers seem to be relatively fearless.Small cars don't have a chance and defensive driving seems to be the exception rather than the rule.I see people reading, putting on makeup, eating with both hands, jiving to the music and of course, talking on their cell phones.The seventy mile per hour speed limit means nothing, absolutely nothing.For this reason, I would not buy a small car unless some form of collision avoidance mechanism was installed having "eyes" at critical points around the car.I know that technology is available today and I feel it's every bit as important as 40 MPG.
What about th e"switch"? Now That's a poor-girls Wrightspeed! & Fun to drive, but may take a bit more detail than you want to deal with. The Mi-EV are just now hitting the west coast. & women out here have strong brang lyalty and told me they would buy an electric Mitsu w/o hesitation. the prediction I would like to make is US LiFePos battery companies finally releasing early "trial " production batteries to US R&D builders as they start producing fresh batteries for OEMs. It could be seen as a patriotic gesture so US battery money can stop flowing into Chinese coffers!
I'd buy a Nano if they were a bit bigger! I'd buy any well built, not-so-expensive, stripped-down car that was, well, a car, and not an infotainment platform. Assuming it was safe enough and somewhat bigger than a sardine-can-sized, sub-compact Geo or Nano, which look just too small to be safe in a crash. If the Nano came in a compact size, like my Nissan Sentra, I'd go for it.
Tata Motors in India came out with such a car -- the Nano, which cost $2,100 U.S. Sales have been much lower than they hoped for, however, even in the economically-depressed Indian market. Hopefully, Tata can hang on until 2025. They might find a big market here.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
A group of researchers at the Seoul National University have discovered a way to take material from cigarette butts and turn it into a carbon-based material that’s ideal for storing energy and creating a powerful supercapacitor.
