Automobile Transmissions - The Model A Ford

My very first ride was a spruced up 1930 Model A Ford Coupe. The transmission was stock and the engine nearly so. It was not a "hot rod" by any means.

It was my "knock around" car as a High School Senior. It had its quirks, but I liked it very much. I think I liked it most because it was my first car. I purchased it with my own saved money, earned working 20 hours a week washing dishes in a local Hospital.

I didn't care that it didn't have an external engine oil cooler or Cruise Control. In 1961, I didn't even know what those things were!

I had driven my father's '52 Ford with the "3 on the tree" manual transmission. I liked it and could drive it well. The transmission was modern, with synchromesh rings that I took for granted - until I learned how to drive again in the Model A.

The Model A had no synchromesh rings in the transmission. Therefore, it had to be driven carefully, very carefully, to avoid damaging the transmission.

Essential to success driving a Model A was a technique called double clutching, combined with a keen sense of what was happening mechanically. It took some time to learn but, once learned, proved a worthwhile effort.

Basically, it was best to start the Model A in first gear. That prevented the multiple thrills of trying to put it in gear with the engine running. It could be done, of course, but why do it if it wasn't absolutely necessary?

Always wanting to make a first gear start also had an effect on where and how I parked the car. I always asked myself, "If I park here, how will I leave?"

I developed what I thought were an effective set of common sense parking priorities.

My first choice was to park the car on a slight downhill grade with plenty of room in front of me to roll easily out of the parking space onto the street. A variation on this was in a not-quite-flat parking lot where I could plan to leave my space first rolling then driving forward.

The parking lot alternative was starting in Reverse, backing out, deftly double-clutching my way into First and driving out into street traffic.

That situation was the very best and I was surprised at how many times I could actually make my first choice happen. Not all the time, of course. But often enough.

Shifting up the gears from First to Second to Third required constant care because the lack of synchromesh in the Model A transmission was unforgiving.

Up-shifting was a matter of increasing speed in First to a perceived shift point. At that instant, the clutch went to the floor while I simultaneously moved the shift lever out of First and into the Neutral "gate" where it would move freely left and right.

Then, as the engine revolutions per minute (rpm) slowly dropped with my foot off the gas, I depressed, and then released, the clutch pedal.

At just the right instant, more sensed than felt, the engine rpm was just what it should be to begin accelerating in Second gear. At that precise moment, I depressed the clutch pedal again as I moved the shift lever up and to the right. If I did it right, the transmission would shift almost silently into Second gear.

I would then release the clutch and, usually, accelerate again in Second gear.

The process was repeated going into Third gear.

1. Accelerate to a desired "shift point" speed in Second gear.
2. Simultaneously take my right foot off the gas while I depressed the clutch pedal with my left foot and, with my left hand firmly on the steering wheel, pulled the shift lever back to the Neutral "gate" area.
3. Then, while the engine was slowing down, I would again depress and release and depress the clutch pedal in such a way that,
4. The instant the clutch pedal hit the floor the second time, the transmission and engine speeds were almost always matched to the point that I could slide the shift lever to the right and back to Third gear. Then I would release the clutch pedal to find the car chugging proudly down the street in Third gear.

Cruising down a rural road or a stretch of CA 99 was a pleasure in the Model A. It was hardly a "performance" car, but the engine seemed like it would run easily as long as I could keep the gas tank replenished.

City street traffic or "stop and go" freeway conditions were a challenge. In those conditions, it was difficult to hold a fairly steady speed, in any gear, while I tried to keep shifting up or down to a minimum.

Modern cars, even the relatively few with manual transmissions, are not so demanding.

Boom in the Indian Automobile Market

In today's world owning a vehicle is not a privilege but an absolute necessity. There are different types of cars manufactured to cater to all sections of society. Even buying a car is much easier than it used to be a decade ago. With all banks offering various types of car loans and other financial aid it isn't that difficult to own your dream car. The only thing is one has to pay an additional amount of interest to the bank, this interest rate is determined on various aspects such as the credit history, amount of loan, time frame within which the loan would be paid of and of course any other terms and conditions pre decided by the bank. Keeping all this in mind it's no surprise to see the sudden surge in the number of cars and traffic on the street.

If you look at the Indian automobile industry it has grown by miles into what it is today. If you looked at it, say around a decade ago, it was a completely different scenario altogether. Back then, there were approximately five different models of cars to choose from. The Maruti 800 dominated the small car or hatchback segment as its known today. The sedan segment was ruled by the Hindustan Motors Contessa and then the Maruti Esteem. The other handful of cars available on sale was the Opel Astra, Daewoo Matiz and Cielo. Today however, things have drastically changed, for the good. The recent boom in the Indian automobile industry is very evident with large international car manufacturers setting up shop in India. Today all the big car companies have a strong presence in India. Right from American giants like Chevrolet to European king pins like Volkswagen and Skoda. All these companies have realized the potential the Indian industry has. The highest selling segment of cars in the Indian market is hatchbacks, as they make for the perfect city car. The horrid traffic situations we are faced with everyday while getting from point A to B are much easier to maneuver when driving a smaller car. And let's not forget about the car parking problems. At times it almost takes you the equivalent amount of time to reach your destination as it does to find parking.

The new hatchback cars that have been launched over the last six months are the Honda Brio, Hyundai Eon, Toyota Liva and even the Maruti Swift new model. This adds to the numerous existing hatchbacks available across the Indian market. With such a wide spectrum of cars to choose from, the biggest mystery would be judging which would be the best hatchback car in India. This massive change in the Indian automotive market illustrates the potential it has and that's why all the international car giants are battling it out with each other and Indian manufacturers like Maruti to gain supremacy in the Indian market.

Maruti Swift new model is without doubt the best hatchback car in India amongst the competing cars in its segment in Indian automobile industry.

Automobile Safety - Crash Avoidance Technology

The rate of deaths every year due to auto accidents is increasing annually at very alarming rates. According to statistics every year 1.3 million people die from road accidents and 50 million get injured from these accidents. Reducing and possibly preventing these accidents is one of major issues auto- makers have been battling for decades. Auto-makers believe it is possible to reduce the rate at which these accidents occur and safe some lives with the new safety features and technologies been researched and developed for new and existing vehicles. A few decades ago, seat belts were the cutting edge safety technology, with the rate of accidents increasing more innovative safety technologies and measures were introduced. Blind spot monitoring systems, driver alert tracking systems, airbags, anti-locking break systems, adaptive headlights that enhance night-time visibility and crumple zones in cars are few of the safety features that are now been integrated in new and existing vehicles.

The latest innovative safety feature which all the car makers are buzzing about is the new crash avoidance technology system. This new system will be based on a technology that will alert drivers of danger and possibly take action on behalf of the driver to prevent crashes from happening, according to auto-makers these technology has the potential of almost completely eradicating car crashes. According to statistics a high percentage of car accidents are caused by the drivers due to bad driving practices or distraction, the crash avoidance technology aims to prevent this as the technology will allow a car detect when a driver fails and act on behalf of the driver to prevent a car crash. Ford, Toyota and Volvo are just a few of the car makers who strongly believe this technology can reduce the rate of car crashes on the road.

There are mixed opinions about this new crash avoidance technology as some drivers and researchers are off the opinion that this technology might actually cause more interruption than help for the driver while others are of the opinion that it will help the driver make better decisions. According to the British drivers association any technology that takes responsibility away from the motorist should be banned, they believe that any technology which requires the driver to do little will make the driver less alert and too relaxed.

"We have to be confident that the engineering can cope with a range of complexities in the same way as a human" explains Peter Rodger, the institute of advanced motorists' chief examiner and former met police traffic inspector. This technology is not close to been developed or completed, the auto industry has and is still developing a lot of innovative safety features for cars, until this technology is finished and ready to be revealed it is not possible to know what its benefits or disadvantages will be.

On the car leasing website, you can find detailed technical specification and information including safety features about new cars from different car manufacturers.
