Most Fuel Efficient Vehicles
With 60 mpg city and 66 mpg highway, the Honda hybrid
has top honors as most fuel efficient in the United
States. With a 1.0 gas engine mated to an electric
motor, the insight was designed to make the most
of the power by using low resistance tires. The
bad things about the Insight include a cramped
interior, seating for two, and a very odd styling.
Fuel efficient mid size car - Toyota Prius hybrid
(60 mpg city and 51 mpg highway)
The Prius, unlike the Honda Insight, is capable of
carrying 5 people plus their gear. The Prius will
generate a total of 110 HP from its gasoline engine
and electric motor. The sleek shape to the Prius
has a low co-efficient drag although Toyota has
managed to do this with a larger, yet more driver
friendly vehicle than the Insight of Toyota.
Most efficient compact car - Honda Civic hybrid
(49 mpg city and 51 mpg highway)
With a reputation of being the cheapest hybrid in
North America, the Civic hybrid takes the great
design of the regular Civic and makes it a lot more
efficient. With an output of 110 HP, the Civic
hybrid is very competitive for the class.
Most efficient sub compact car - Volkswagon diesel
(37 mpg city and 44 mpg highway)
The Volkswagon Beetle diesel is ahead of even the
sub compact hybrids. Making 100 HP, the Beetle
diesel may not sound that powerful, although the
177 lb-foot of torque will put shame on every
other vehicle in the same class.
Most efficient station wagon - Pontiac and Toyota
(30 mpg city and 36 mpg highway)
The Pontiac Vibe and Toyota Matrix are both the
result of a joint venture of Toyota and General
Motors. Both vehicles come equipped with Toyota
engines, although a lot of the design and
engineering came from General Motors. Both the
Matrix and the Vibe are versatile with active
lifestyles. With a fuel efficient 1.8L 4 cylinder
that produces 126 HP, the Matrix and the Vibe
aren't going to win a street race although they
make up for it with smoothness, efficiency, and
Most efficient large car - Hyundai Sonata
(24 mpg city and 34 mpg highway)
The Sonata is a major surprise, beating out very
stiff competition. The 2.4L 4 cylinder engine is
very smooth, responsive, and powerful. The
suspension however, is soft, and geared more
towards comfort than handling. This isn't a BMW,
although the build quality is great, clearly
demonstrating that Hyundai is no longer a second

Advantages Of Diesel Engines
Diesel Engines And Well Known Gas
In passenger cars, the diesel engine has never really caught on. During the middle to late 70s, diesel engines in passenger cars did notice a surge in sales due to the OPEC oil embargo, although that is the only real significant...
Diesel Fuel Quality
The designs of diesel engines striving to increase performance have made a lot of advancements in engine fuel delivery to the combustion chamber. The diesel engines of today are much quieter, smoother, and also more powerful. The quality...
As you probably already know, diesel engines get better fuel economy than gas, simply because they don't need to burn as much fuel as gasoline engines to get the same amount of power. Diesel engines are built heavier than gas engines, to...
Diesel Versus Spark Engine Ignition
As you may already be aware of, diesel engines are more efficient than gasoline engines of the same power, resulting in much lower fuel usage. For an efficient turbo diesel, the average is 40% more miles per gallon. The higher compression...
Gas engines are known as internal combustion engines and are divided into two general classes, specifically two cycle and four cycle engines. A cycle of an engine represents one stroke of the piston or one half revolution of the crank...
Gas Tractor Versus Diesel Tractor
There are many different reasons as to why a diesel compact tractor is superior to a gasoline garden tractor. First of all, the diesel engine doesn't have the parts that normally wear out or give problems. There are no spark plugs,...
Gas Trucks Versus Diesel Trucks
If you plan to use your truck like a car, desiring quick, quiet acceleration and rarely ever haul a heavy load and don't plan to it for a long time, you may want a gasoline engine. Gas engines run smoother, fuel is easier to find, and gas...
Gas Versus Diesel
Cost Due to the high compression ratios and resulting high cylinder pressure in diesel engines, they must be built to withstand a lot more punishment than gas engines. The parts that are spruced up include a thicker block and cylinder...
How Diesel Engines Work
When gas is compressed, the temperature of it will rise, with diesel engines using this very property to ignite the fuel. Air is then drawn into the cylinder and compressed by the rising piston at a much high compression ratio than gas...
Hydrogen Boosted Gas Engines
With the ever increasing cost of gasoline prices, auto makers are having to work overtime to cost effictively improve the fuel economy, while still meeting the strict emission requirements of today with gasoline engines. One ideal and...
