Modern Cars Give More Fuel Economy

It’s found that modern cars give slightly more fuel efficiency than old cars. This is practically proved in a report by the journal of Energy Policy published in United States. The study was conducted recently on vehicles manufactured from 1923 to 2006. The report reveals that since 1920 there has been a little progress in fuel efficiency statistics. Researchers unveiled that the overall fuel economy of vehicles in United States in 1923 was 5.9 km/l. But in 2006, the average fuel efficiency was 17.3 km/l.

They found that overall fuel efficiency decreased to 5 km/l in 1973 from the earlier 5.9 km/l in 1923. However, there was a rapid improvement by 1991 when cars reported 7.1 km/l of fuel efficiency. Also, from 1991 to 2006 the improvement was less than 2 percent compared to earlier years. Whereas, fuel efficiency of cars improved from 5.6 km/l in 1973 to 9 km/l in 1991, but after 1991 there was only a marginal improvement of 9.5 km/l in 2006.

Though car manufacturers have introduced many engines that consume less fuel, it has been noted that still some of the modern cars consume same amount of fuel as old cars. They should stress more to bring in new technologies in the car industry that ensure improved mileage.

It is amazing to note that today's cars have not made much progress compared to cars used by our grandfathers. It shows that car manufacturers have taken their responsibility very lightly. While they kept waging wars they completely forgot about their responsibilty to manufacture high fuel efficient vehicles. They are waking up to the reality only only the professors should be thanked for their study.

Not only this report, but many other earlier reports too have suggested that there has been no significant improvement in fuel efficiency. It makes us believe that car manufacturers have something to hide from the public. Thanks to the Indian government, car manufacturers will now be compelled to publish their fuel efficiency and emission reports for consumers. It is a step in the right direction.

I must say that it’s a very interesting article. I get a lot of knowledge from here. Beside that, your blog is so popular among the searchers from search engines. It means yours is great!

You got a really useful blog I have been here reading for about an hour. I am a newbie and your success is very much an inspiration for me.

I am not much of a guy who thinks in so deeply about web design but I think your post had some valid points in it. Like designers are forced to design stuff within the limited code available and not go beyond it, their innovation is somewhat limited but still I think Web Design won’t die! I agree that Amazon and other some big sites won’t have a blog but now a days it’s very important to have some sort of option available so people can quickly communicate their thoughts. I think Amazon if wants to shift it to that, they can get a customized CMS for themselves.
