Question about cars???

Question

I know there is a lot of car models that been around for a long time such as Honda Accord, Toyota Camry, Nissan Altima, Nissan Sentra and Toyota Corolla. Every few years they come out with a new model. What I want to know is, I know they change the look and add some newer features, but what do they do with the horsepower and speed. Every few years sometimes they say they add more horsepower and speed. Do they always do they every few years? Do they just keep adding more and more horsepower and speed every few years, or do they keep the car made similar because its the same model. If you drove a Honda Accord thats 20 years old and drove a brand new one, would the brand new one have to be faster? If they did that, do they just keep adding more horsepower and more speed every few years or do they keep the car made similar but with a newer look? I know they add new features with the time such as navigation system, power windows, power seats. Nissan Sentra is supposed to be inexpensive compared to the other Nissans. Are they supposed to keep making it more and more luxury until its a higher class or do they keep the model make similar but with a newer look? I want more details on this

Answer 1

it is very dependant on the car model and the market trends. right now what is popular in a vehicle is a good fuel economy. so companies are doing everything they can to do that. they will also offer different engine options. for instance the camry comes with an option of a 4 cyl. or V6. that way they can appeal to different areas of the market.

often times car companies can get better fuel efficiency by redisigning the motor and a by product of this efficiency is more hp. there are time in history where power has been reduced in an effort to clean up the enviroment or be better for gas mileage without altering the engine. if you look at older cars that have been around for a while you can see this trend. for instance in the mid 70's manufacturers were required to clean up their vehicles emmisions. the mustang went from a stout 300+ hp on there v8s to as low as 150 hp. and in 1992 the mustangs hp in the v8 5.0s dropped from 225 to 215.

manufacturers play the market trend. right now people arent really caring so much about power so the manufacturers are focusing on luxery, sound systems, and fuel economy.

of course there are always the few exceptions

some years they don't change anything.

unless the car is going to be redesigned.

for example the 09 Toyota Corolla

The all-new 2009 Toyota Corolla is offered in five versions, base, LE, XLE, S and XRS. The standard 1.8-liter engine produces 132 horsepower and 128 lb-ft of torque with estimated fuel economy of 27/35 city/highway with either a 5-speed manual or a 4-speed automatic transmission. The XRS receives a 2.4-liter that produces 158 horsepower and 162 lb-ft of torque and is rated at 22/30 city/highway with either a 5-speed manual or a 5-speed automatic.

if makers don't change a lot, they do try to make the engines better, more horsepower or get better mpg from year to year.

Electronic stability control is easier to find in this generation, and curtain air bags are becoming standard.

The Accord is Honda’s midsize car that is completely redesigned for 2008. With more dramatic styling and an increase in size, the 2008 Accord Sedan offers the most room and comfort ever offered by an Accord. The 2008 Accord includes three firsts for Honda in North America: next-generation Variable Cylinder Management, interface dial controller and dual-chamber driver’s and front passenger’s side airbags. Offered in both sedan and coupe versions, the coupe receives more aggressive and emotional styling to differentiate it from the sedan. The Accord was first sold in the U.S. in 1976 as a compact car and has grown larger and more luxurious, moving into the midsize category in 1998.

The redesigned 2008 Honda Accord features a number of firsts for the Accord model including the use of Advanced Compatibility Engineering (ACE) body structure, Vehicle Stability Control for all trim levels, Active Noise Cancellation on a nonhybrid Accord and active front-seat head restraints. Consumers can choose from a 268-horsepower 3.5-liter V6 or 200-horsepower 2.4-liter 4-cylinder engine. Eighteen-inch wheels are available on Accord V6 Coupe, 17-inch on Accord 4-cylinder and steering-wheel audio controls are equipped for all trim levels.

On the contrary, many older vehicles got pretty good horsepower, considering how technologically handicapped they were.

The main reason new motors are constantly being introduced, is the ever-tightening restrictions on exhaust and sound emissions.

The drawback? More fuel is wasted. That's why cars today are not really that much better on gas than 20 years ago.

Case in point, I had a Chevy V-8 Station wagon, 1987, that got over 25 mpg highway. My four-cylinder truck, 99, has an engine that is less than HALF the size, and has half as many cylinders. But it only gets 22 mpgs. That is some backwards math!

I've seen plenty of examples of this, off the US Gov't MPG website. It is amazing that we can be so concerned with emissions, that we are willing to use more fuel to get the job done.

Regardless of what the Green crowd says, emissions controls are the main ingredient in decreased fuel economy (next to neglected maintenance schedules). Ask any hot-rodder what the first thing is to be removed from a vehicle is, in order to make it faster.

Also, car companies will tell you stuff is new for that year, or else there would be no reason to buy new. If they didn't change the model, nobody would know if your car was a 99 or an 09. They would lose sales, to used vehicles.
