The job of an oxygen sensor in a vehicle is to compare the oxygen content coming out of the exhaust to the oxygen content in the exhaust stream. This helps the vehicle computer determine whether to enrich or lean the fuel mixture, allowing the catalytic converter to operate more efficiently and reduce emissions into the environment. Exhaust byproducts can often block the sensor’s element over time causing poor fuel economy and increased emissions. (more…)

GM Ford Alliance To Improve Fuel Economy
Wednesday, October 3rd, 2012A manufacturing alliance between General Motors (GM) and Ford, expected to be unveiled next month, will have the two rival companies developing automatic transmissions designed to improve fuel economy. The alliance could save the companies billions of dollars as they work towards meeting demanding federal fuel economy regulations set for 2017.
GM and Ford have already successfully worked together building six speed automatic front wheel drive transmissions in 2002, introduced in 2006 in approximately thirty different models. Both companies are currently developing 8, 9, and 10 speed transmissions for front and rear wheel drive cars and light trucks and they hope that the agreement will not only speed up technological developments, but will allow them to reduce manufacturing costs.
Packing more gears into the compact transmission housings used in smaller vehicles is an increasingly tricky challenge, according to engineers. Automatic transmissions with more gear ratios and more sophisticated electronic controls are crucial to improving fuel economy but the limited space of compact and subcompact cars makes it difficult. The lack of space is one reason that subcompacts like the Ford Fiesta and Chevrolet Sonic do not achieve higher fuel efficiency than the larger Ford Focus and Chevy Cruze. Longer vehicles also have lower aerodynamic drag, which helps overall efficiency.
Developing transmissions in house will not only allow GM and Ford to tailor the components to suit their needs, but will eliminate royalty costs for licenses and intellectual property rights charged by their current gearbox suppliers. The new transmissions are expected to reach the market by 2015.
New Generation Automobile Buyers
Monday, October 1st, 2012A trend in the automobile industry shows that the younger generation is not as interested in driving as the generation before. Not only are they buying fewer vehicles, but many don’t even have drivers license. Some reasons for this change include:
- The younger generation are more connected through internet and iPhones making them less reliant on owning transportation.
- Many live in urban areas where everything is at a walking distance, there is good public transportation or they have access to car sharing programs.
- Young people are facing soaring tuition costs, and the money they’re earning in their part-time, summer and first jobs is going toward paying for school and rent. Even if they could afford to buy a car, insurance is expensive and gas prices keep rising.
- They have grown up in an era where they have had much more exposure to environmental concerns.
Automakers have known for a while that they were going to have a problem selling vehicles to this generation but are unwilling to believe that they will not want actual cars. As a result, automakers spend more time talking about how well their cars interact with an iPhone than they do about engine performance, ride, and horsepower. Technology such as voice recognition are important to many of the younger drivers because it allows them to safely drive while still staying connected.
They are trying to attract the younger urban buyer by developing a fashionable small car that is easy to park and uses less fuel. Car makers have begun shrinking the size of engines, subtracting cylinders while adding turbochargers to maintain horsepower and acceleration. Smaller engines have become a selling point even in the United States, which would have been unthinkable a few years ago. The idea of electric vehicles has also become more widely accepted.
As these technologies become more common they will also become more affordable, hopefully attracting more buyers. While today’s young buyer seems more open toward the trend of smaller autos with more features, car makers have not abandoned the hope that as this generation gets older and becomes parents they will graduate towards roomier vehicles.
Tesla Supercharger Stations Unveiled In California
Wednesday, September 26th, 2012Tesla Motor’s highly anticipated charging network has finally been unveiled to the public with the revelation of it first six supercharger stations. According to Tesla, the stations will safely deliver up to 4.5 times more electricity to the battery giving approximately half a charge in half an hour. It will do this by using special cables that connect directly to the battery, bypassing any on board charging equipment. The most unique thing about these charging stations is that many will be equipped with solar cells mounted on the weather canopy that will generate more energy over the course of a year than is consumed by Tesla vehicles using the supercharger stations, resulting in a positive transfer of power back to the electricity grid. Current active stations in California can be found in Barstow, Hawthorne, Lebec, Coalinga, Gilroy and Folsom. By 2015, Tesla hopes to expand their supercharger network to over 100 stations.
Gas Prices No Longer Affect Auto Sales
Saturday, September 8th, 2012Gas prices no longer seem to be as big of a factor when it comes to consumers purchasing vehicles as automobile manufacturers build more fuel efficient cars. August was a perfect example of this as gas prices rose and automakers reported sales also grew by almost 20%. According to analysts, the wide rang of fuel efficient, hybrid, and electric vehicles have made it easier for consumers to spend their hard earned money as the average car and truck on the road reaches over 10 years old. The biggest gains came from Toyota and Honda who experienced low sales last year in the wake of an earthquake and tsunami in Japan. Detroit automakers also showed substantial gains with the introduction of their high mileage car lineup. General Motors (GM) United States sales grew over 10%, driven by strong sales of the Chevrolet passenger cars like the Sonic subcompact and the Spark minicar. Ford also reported an almost 13% increase with the sales of the Focus compact car and the Escape, one of the smallest sub compact sport utility vehicles (SUV) on the market. According to analysts the strengthening industry has surpassed expectations and has helped automobile manufacturers keep inventories stable and sales incentives relatively low.
