Most Fuel Efficient Vehicles

Here are the most fuel-efficient vehicles:

 

Overall - Honda Insight hybrid – 41mpg city 44mpg highway

This Honda hybrid is the most efficient vehicle in America.  With an in-line-4-cylinder gas engine, connected to an electric motor, the insight’s low resistance tires help it make the most of its power.  The cons of this vehicle include the cramped interior and awkward design.

 

Fuel efficient mid size car - Toyota Prius hybrid 51mpg city and 48mpg highway

Being a larger car is one advantage the Prius offers over the honda insight: it allows up to 5 people to fit in with their gear. The Prius has a total of 134 net HP from its gasoline engine and electric motor.  The Prius’ shape offers a sleek low drag design that helps in the car’s fuel efficiency.

 

Most efficient compact car - Honda Civic hybrid - 44mpg city and highway

Reputed for being the most inexpensive car in North America, the Civic hybrid takes the sleek design of the Honda Civic and makes it even more fuel efficient.  Providing a 110 HP push, this is a clear competitor for it’s class.

 

Most efficient compact hatchback – Toyota matrix – 35mpg city 45mpg highway

The Toyota Matrix comes equipped with an efficient Toyota engine, however the design and engineering came from General Motors. The matrix is versatile and for active lifestyles.  This car sought for it’s elegance and maneuvering, although it wont win a street race any time soon with it’s 132HP.

 

Most efficient sedan - Hyundai Sonata - 24mpg city and 35mpg highway

The Sonata’s 2.4L 4-cylinder powerful 200HP engine is very responsive, and smooth.  With a suspension geared towards comfort more than handling, this car is great on long trips.  The build quality of this car is great, and reaffirms that Hyundai is not a second grade manufacturer.

Gasoline Engines

In internal combustion engines, such as for gasoline engines; the piston sparks up the gas in the cylinders, resulting in a powerful burst pulling the piston back and forth, and making the shaft rotate, around its axis. There are four-stroke and two-stroke engines, a two-stroke engine will consume the fuel and at each revolution, two cycles make one complete revolution, so it’s called a two-cycle, or two-stroke engine, a four-stroke engine gets an impulse every second revolution.

The four stroke engine

This four stroke engine is the most commonly used in cars.

 

There are particular advantages to each type of engine, and uses. Many motorboats use two-stroke engines, whereas most cars use four-stroke engines.

The two stroke engine

The two stroke engine is used most often for motorboats

An engine's horsepower tells you how much push you can get with it. The theoretical horsepower called IHP (indicated horse power) which may be determined mathematically using engine's dimensions, such as length and size of the cylinders, or amount of cylinders, as well as the revolutions per minute.

The brake horse power, BHP, is another relevant number, it gives the HP of the engine, before it has been slowed by the differential, the water pump, the gearbox, the alternator, and other components like the muffled exhaust system, or power steering pump, etc. How close this measure will be to the IHP depends on the mechanical imperfections of the engine. It's commonly 70-90% of the full IHP.

Having a high horse power means a more powerful engine, but this may also lead to lower fuel efficiency and greater fuel consumption. Gasoline engines ignite fuel with a spark plug, contrary to diesel engines, which ignite from the heat created during compression. Nonetheless, gasoline engines are preferred over diesel for passenger vehicles, due to to the higher speed, even though there is less torque.

Gas vs. Diesel vs. Hybrid War

Diesel, gas or hybrid engines, the differences and similarities of today’s vehicles.

Everyone’s suffering from continuously rising gasoline prices, and it’s affecting our entire budget. Maybe you want to spend less money on this often-imported commodity, or you feel concerned by the effects of fuel combustion on the environments, or perhaps feel concerned by the fact oil and gas are non renewable resource, and we’re running out.

Fuel economy

The fuel economy figure of your vehicle determines how much fuel you will be consuming per distance. Often times this figure is in MPG or Km per liter. Studies have demonstrated that the average driver only gets about 75% of this figure.

You can nonetheless use this figure to determine the gross fuel economy of your vehicle, prior to purchase. You can compare the fuel economy figure to get an approximate estimation of which one will be more efficient than the next.

 

Hybrid pricing

Hybrid vehicles are often more expansive then their fuel counterparts, this is due to a more complex engine, that allows greater fuel economy and efficiency. The price difference can be of several thousands of dollars. However, if you intend to use this car for the long run, you might save much more.

Hybrid cars do consume a lot less gas for long distances. This is one formidable way to save money and still go the distance. Hybrid vehicles are becoming more and more popular, and they are no longer the everyday consumer. Remember that paying the extra money right now for a hybrid vehicle will save you tons of money in the long run on fuel.

Diesel efficiency

Diesel vehicles also have higher fuel economy; they cost less than hybrid vehicles too.  It’s another way to save money on fuel expenses. Diesel engines have much greater torque than their gasoline counterparts. These vehicles do emit a lot of gases, and might not be as beneficial to the environment as hybrids are.

The best thing to do when you’re buying a car is to compare the figures and facts of the different types of engine, rather then aiming to get the best price right now, do think about the long run and fuel consumption.

Diesel Versus Spark Engine Ignition

Diesel Versus Spark Engine Ignition

Diesel engines of the same power as their gasoline counterparts are more efficient. That comes to an average of 40% more miles per gallon for an efficient turbo diesel. Diesel contains 15% more energy per unit volume than gas, along with a higher compression-ratio for diesel engines, helps raise the efficiency of diesel engines.

Naturally aspirated diesel engines are much heavier than their gasoline counterparts, for a couple of reasons; first of all, the engine needs more diesel to obtain the same amount of power from the engines, therefore a larger capacity is required. It’s harder to get the appropriate fuel to air ration in a diesel engine fast enough, therefore the rev limit is slower.  Secondly, the higher combustion pressure required for diesel ignition, means the engine needs to be stronger.

Diesel engines produce very little carbon monoxide, however they do sometimes emit black soot, which consists of several harmful gases for the environment. This may be caused by problems in the engines, for example injectors that don’t atomize the fuel sufficiently enough. Or perhaps an inaccurate fuel to air ratio is combusted, and there is not enough air to burn the leftover fuel. This leftover is then ejected as  soot.

Diesel engines are mainly used in big trucks and heavy machinery due to their torque reaching a maximum much sooner than gasoline engines. Diesel engines have their torque peak in a very low speed range; this means a greater control when starting from rest. Essentially allowing the engine to carry heavier loads at comparatively lower speeds to gasoline engines.

Diesel engines are more durable too, this is due in part to the more massive structure of the engine. The change in pressure during a combustion cycle is also much less damaging than in a gasoline engine. Unlike gasoline engines, diesel doesn’t use an electrical ignition system; therefore they have a greater reliability.

The durability of a diesel engine is greater than that of gasoline due to the greater lubricant nature of diesel, compared to gas. This means less damage to the piston rings and cylinder bores. It’s not uncommon for diesel engines to go over 250 thousand miles or more.

Overall, we’ve seen the benefits of a diesel engine over a standard gasoline engine. It’s a great way to save on fuel prices, and also on the durability of your vehicle. You’ll get more torque, and you’ll have more reliability with a diesel rather than spark ignition engine. Although they cost a bit more, you’ll definitely notice an upside in the long run.

Diesel Fuelled Passenger Vehicles

Diesel Passenger Vehicles

With current day economic and environmental situations being what they are, diesel vehicles have been getting more attention, both for their fuel economy and effects on climate change.

This interest is spawned by the potential for diesel vehicles to reduce consumption of fuel in passenger vehicles, also increasing fuel economy, as well as reducing carbon emissions. Indeed, diesel fuelled passenger vehicles today are more efficient than their gasoline equivalent, reducing by over 30% carbon emissions.

Several automakers are contemplating reintroducing diesel into passenger vehicles, in Europe where over 50% of vehicles are diesel. These goals are prompted by the search for a solution to the global warming problem caused by current engines on gasoline fuels. It’s also a quick fix for manufacturers that are having a hard time meeting federal fuel standards for light trucks.

Though diesel fuel does offer great improvements in the fuel economy, it’s benefits on climate change are modest.

Diesel does achieve higher MPG than gasoline, however many are concerned by the impact diesel vehicles will have on the environment. Diesel combustion in the engine sometimes causes black sooth to come out of the exhaust. This emission is actually pretty bad for the environment.

Diesel still is better than gas, and diesel engines are being improved to better reduce the impact on the environment. The current popularity of diesel can be attributed to the spiking fuel costs. This is mainly because Diesel maintains a lower price than gas.

If you’d like to reduce your impact on the environment, and reduce your fuel expenses, diesel fuel is definitely a keeper. One quirk is the higher price of diesel engine vehicles, but knowing that you can achieve greater mileage with diesel fuels, for cheaper costs, diesel is the way to go.
