6 Cylinder Engine Into A Car example essay topic
The special Waffle-ball shifter cycles a six-speed gearbox similar to the one in the Audi TT Quattro. To keep it compact, VW stuffs this odd unit with two separate lay shafts plugged into two separate final drives, a 3.88 ratio for first through fourth and a 3.10 ratio for fifth and sixth. With this car's first and sixth geared nearly identically to the current five-speed GTI's first and fifth, the extra ratio resides somewhere in the middle and serves mainly to reduce the gaps separating the ratios of the current box. Keeping the engine spooled is easier, and unlike some six-speeders, this box has an overdrive you " ll visit every day.
The Anniversary Edition shredded the run to 60 mph in 6.5 seconds and topped the quarter in 15 flat at 93 mph, mere eye blinks off the times of a 225-hp Audi TT and a thorough drubbing of the V-6 GTI. That car reached 60 in 7.7 seconds and the quarter in 16.1 at 89 mph, while the old 150-horse turbo GTI did it in 7.3 seconds and 15.9 seconds at 88 mph, respectively. Although the spring rates and the settings of the Monroe shocks are identical to those for U.S. -spec Gti (Europe's base GTI is actually softer, so Germans must pay extra for the Yankee setup), the rear twist beam mounts on stiffer rubber bushings instead of squishier oil-filled units. They inject more neutrality into the steering by helping hold under steer-inducing camber changes in check. The body has also been lowered, the nose riding 0.8 inch nearer the earth while the tail sags an inch lower, and the brakes are larger. It also sways less, the front tires ruffling the ears with nothing more offensive than the squeaks and chirps from their scrabble for grip.
Around the skidpan it pulled 0.88 g, sideways force that would have sent the V-6 GTI (at 0.81 g) spinning into oblivion. Better yet, there's little sacrifice to the GTI's ride, which over the highway feels suspended by air bearings and across disintegrating pavement is comfortably damped. Because the springs are stock items, they still cushion the body from the thin, unforgiving sidewalls. What's left of bump energy dissipates in the Golf's rigid, tungsten-grade structure.
This GTI doesn't come cheap for a wee car, but it will represent an Audi on the clearance rack if it ever comes to the States. If you can find better driveway shade, buy it". In the way of performance few take the glory like the GTI does. The GTI is continuing to fight the reputation that this fourth-generation Golf is low-performance compared with previous generations.
Last year VW pumped the horsepower of the 1.8 liter turbo GTI to 180 and put a new four-valve cylinder head on the cast iron 2.8 liter VR-6 to raise horsepower from 174 to 200. VW is also considering bringing stateside a European tune handling package in 2003 that will make the GTI a performer. The VR 6 remains one of the largest engines available in a car of this size. It comes exclusively with a six-speed manual transmission, while the 1.8 T is available with a five-speed automatic or manual. All of this makes for a great Volkswagen vehicle. From a quality standpoint, the fact that the car is German made should be speak for itself.
If it doesn't just look at the warranty of the Volkswagen. Basic warranty 4 years/50,000 miles (whichever occurs first) New Vehicle Limited Warranty. Wear & tear items and adjustments excluded after initial 12 months/12,000 miles (whichever occurs first). Powertrain Now look how it compares to other dealers of the same standard. From it you can see it has the best basic and the best powertrain of all. Some match, but only in one category not both.
These are also very respectable names too. Volvo, BMW and Mercedes-Benz are top line car manufactures. Dad, you said you wanted one of these brands while you were still considering the luxury sedan. I'm sure there warranty and dependability were one of the reasons you looked into these. I am doing the same and Volkswagen beats all three. Honda is also known for there quality in cars.

The 1.8 T comes in three different powers. The GTI has the most powerful that VW makes. They come in 150,170, and 180 hp. The two lower engines are used in the beetle, and the luxury passat.
The principle behind the turbo is what makes these small engines so powerful. Turbochargers increase power output by pushing cooler air into the cylinders. Exhaust from the cylinders spin a turbine, this spinning turbine is attached to a compressor. So if the turbine spins so does the compressor. This helps the compressor do its job of sucking air in through the front of the car. The second job of the compressor is actually compressing the air.
When this air is compressed it naturally becomes hotter. This is do to Charles's law of relating the volume of gas to temperature. As volume goes down heat goes up (thanks to Mrs. Voor stad for that.) The problem with hotter air is that it creates less of an explosion in the cylinder than if it were colder air. So in a turbocharger the air is sent into an intercooler where it is cooled to produce bigger explosion and more power. This is essential how VW managed to increase the power of the GTI by 30 hp. The VR 6 is a whole different story.
The VR 6 doesn't have turbo. Its real innovation is that VW was able to fit a 6 cylinder engine into a car this small. It is common practice that engines that follow the "v" shape design be at a 90 degree angle. This however takes up tremendous space. The other way to design an engine is through what is called an inline. Inline engines have all of the pistons in a straight line.
This makes the width smaller and the length longer. See the diagram I made below to see the difference between all three designs. That's why the engineering of the VR 6 is so great. This design is almost a hybrid of the two.
It gets the advantages of both designs, in one! - Compact design fits in smaller spaces (lighter) and makes for more powerful and better performing cars - Lots of torque due to the sim. Ti inline design - Great handling and balance do to V design - Smoothness of six cylinders - Reduced emissions - Extended engine durability due to lower piston speed per mile In all VW cars form follows function. There are no bells and whistles.
If it is on the car it is there for a reason. This seems to be the philosophy of VW. That doesn't say that VW are boring, it just states everything has a purpose and is designed to be functional. All the VW sunroofs are powered and have a whopping 15 settings. That's right 15 different positions. The floor mates have buttons to help secure them to the floor to reduce the amount of dirt getting under them.
They even have trunk outlets incase of a flat ball requiring an electric pump, video game plug in, laptop and cell phone recharge. This prevents cords cluttering the area between the driver and passenger seats. They have a self dimming rear view mirror as well as simple blue and red instruments. This is easy, yet easy to see on the eyes. The red is especially useful when driving in the dark. They even top it off with an upgrade in wheel size, for a better defined and imposing look.
The engineers at VW don't know when to stop. They seem to be obsessive about perfection..
