Although hybrid cars are the rage, and there are all kinds of alternative energy sources on the horizon, hybrids are cost prohibitive, usually ranging $3000 to $7000 more than the gas only version of that model. However, instead of changing fuel sources, some automotive companies have been using a new type of transmission to improve fuel economy, lower emissions, and actually make vehicles faster without adding to the sticker price.
These companies are using a continuously variable transmission (CVT) and instead of having set gear ratios (or gears), it constantly varies the gear ratios, as well as engine performance, so that they both operate at their most efficient level in any driving scenario.
Because these key components of the power train are at their peak performance at all times, fuel economy is improved by 6-8% and carbon dioxide emissions are reduced by 10%.
Although these figures may not sound impressive, the gas savings increase the highway mileage of most vehicles by 4 to 6 mpg, which adds up pretty quickly at $3/gallon.
The CVT's potential for reducing emissions is also significant. As Carlos Ghosn, CEO of Nissan Motor Company, said, achieving his goal of selling one million CVT equipped vehicles by the end of 2007 will have ?the same effect in terms of reducing CO2 emissions as selling 200,000 hybrid electric vehicles.?
Since there is no shifting between fixed gears, there is no ?shift shock? or jerking sensation, which makes them exceptionally smooth to drive. CVTs also do well in hilly terrain since there is no ?gear hunting? or bogging down on a hill, followed by a loud, violent downshift, which also contributes to its superior acceleration.
You may be wondering why this isn't in every car if it is so great. Well, every year, more vehicles in the American market add CVTs as an option, though it has happened quietly, as many people are leery of new technology, especially in cars.
The CVT is actually quite old although it is new to American automobiles. The concept was developed by Leonardo DaVinci and was first patented in the late 1800's for industrial applications. The CVT has been used in Asian and European vehicles since the 1950's, but until recently CVTs could not handle the power that American drivers demand from their cars. However, CVTs have seen widespread use in snowmobiles and Formula 500 racing where they have a reputation for extending engine life and being much easier to rebuild than either a manual or automatic step transmission.
So where can you test drive a CVT-equipped vehicle? Well you can go to dealerships selling Ford, Dodge, Audi, or Mini-Cooper, to name a few, although a Nissan dealership may be the best place to go. In order to hit their goal of one million CVT sales in 2007, they have installed CVTs in nearly every sedan in their lineup, including the best selling Altima, Maxima, and economical Versa (as a side note, Nissan has also made side curtain airbags standard in these models, improving safety and reducing insurance costs).
Although you may not have the budget for a hybrid vehicle or cannot wait for that miracle fuel to hit the market, you can take it easy on the environment, as well as your checkbook, by checking out a few cars with a CVT.
Modern Automotive Technology Duffy
More than 100 Americans die every day in automobile accidents. In fact, over the last century, more have perished due to car crashes in the United States than in all the wars the country has fought. Although this is a horrible statistic, the 2006 Traffic Safety Annual Assessment from the National Highway Traffic Safety Administration (NHTSA) reported the largest U.S. decline in terms of both number and percentage since 1992. This vigorous reduction is a goal that automotive engineers are striving to continue year after year.
Innovative automotive engineering can make cars safer, but at the same time, drivers must also strive for improvements. Many motorists at one time or another can recall either almost being killed on the road, stories of road-rage or helplessly observing an accident happen right in front of their very eyes. According to a 1999 Public Broadcasting Service (PBS) special, Escape! Because Accidents Happen - Car Crash, the roads are, indeed, a major threat. What's more, an automotive magazine recently published statistics which reveal that more than 95% of these accidents involve some degree of (poor) driver behavior.
Indeed, some Americans may not rank amongst the best of the world's drivers, but it's not entirely due to operator error, either. Poor roadway maintenance, roadway design and equipment failure have also been referenced as top factors affecting crashes. Frequently, driving behavior interacts with at least one of these other factors to produce a grave situation.
Aside from rectifying the paradox that the majority of drivers consider themselves more skillful than their counterparts, better engineering and innovative automotive technology could help improve roadway safety. Today, it is well understood that properly deployed cushions of air (i.e., airbags) can assist in saving lives. In much the same way, in the previous generation, the advantages of good restraining devices were discovered. Car navigation systems particularly aid the directionally challenged - and, what about using those fancy "carputers" for technology to help make our roads safer? Automotive engineers are answering this need by developing "active safety systems." These systems can help reduce the number of crashes and minimize the effects of crashes that do occur.
Automotive safety is taking on a new role as active safety components are beginning to gain ground as technology and development improve. Some suppliers are developing specialized active and passive safety systems. These include forward collision and lane departure warning, electronic stability control, pre-crash mitigation, side alert systems, active night vision and road sign and pedestrian recognition - all of which do about what they sound like they should.
Imagine how different driving could be if motorists were warned before they were about to sideswipe a fellow road warrior, alerted before missing a stop sign or even just able to see what's ahead at night. Such technologies could prove paramount to safety as humankind steps into an era of even more cars, faster speeds and the repercussions of recent population explosions.
A European study reported that 80% of drivers involved in accidents believed the other party could have done something to prevent the mishap. But what if everybody just stopped blaming each other and became better drivers? What if existing technology was utilized and built upon to reduce the number of traffic fatalities? In the end, determining fault matters more if something can be done about it, such as discovering ways to prevent other collisions.
It can be scary out there on bustling roadways. All one has to do is hop on a busy interstate or horn-chorused city street to realize roads "ain't no horse trails." In the chaos that is modern driving, these new "active" safety systems are promising.
