Import Vs Domestic

Import vs. Domestic

Muscle cars have always been a big in the United States such as the Ford Mustang, Chevrolet Camaro, and Chevrolet Corvette. These cars are some of the most popular cars for the past 25 or more years, but over the past 10 years, Japanese cars are becoming more and more popular. Many people who are into muscle cars despise these "imports" and people who are into these imports have the same feelings toward muscle cars. These two types of car lovers have a strong dislike for each other and these cars. Many people see both muscle and import cars as just a car and don't really see the big deal between the two cars.

One of the major differences between the two is the type of engines they have. Most muscle cars have a V-8 or even a V-10 with a large displacement. These engines produce a large amount of horse power and create a lot of torque at the higher RPM (Revolutions Per Minute) range, but to fit these large engines, they need large cars to put them in. On the other hand, imports have a much smaller, inline 4 engine, and because it has a smaller engine, it can fit into a smaller car.

To make comparing easier, a 2004 Ford SVT (Special Vehicle Teams) Mustang Cobra and a 2000 Acura Integra Type R will be used as the comparison. The engine in the Mustang is a 4.601 liter, 280.8 cubic inch V-8 engine with 32 valves DOHC (Dual Over Head Cams), sequential electronic fuel injection, and an Eaton Generation IV roots-type supercharger, with a TTC T-56 6 speed Manual creating 390 break horse power at 6000 RPM and 389 foot pounds of torque at 3500 RPM. It has a 0-60 mph time of 4.5 seconds, a quarter mile time of 12.6 seconds at 112 mph, and has a limited top speed of 155 mph. The Integra has a B18C5, 1.797 liter, 110 cubic inch, 4 cylinders, 16 valves DOHC VTEC engine. It creates 195 horse power at 8000 RPM and 130 foot pounds of torque at 7000 RPM. It has a 0-60 mph time of 6.5 seconds, a quarter mile time of 14.7 seconds, and has a limited top speed of 135 mph.

Even though the Integra is slower than the Mustang, the Integra engine has something the Mustang engine does not have, and that is a VTEC. VTEC is short for VVTALEC which stands for Variable Valve Timing and Lift Electronic Control. The heart of the VTEC is the design of the camshaft, with three lobes for each pair of intake and exhaust valves, plus the corresponding rocker arms that actuate the valves. At low to midrange engine speeds, the valves are opened and closed by the rocker arms following the outboard lobes have been ground to provide relatively low lift and short duration. Once certain engine-speed threshold is crossed, the VTEC computer sends a signal to a valve that uses engine oil to pressurize small pistons in the rocker arms. This locks the two outboard rocker arms to the center arm, which aligned with a higher lift, longer duration cam lobe. The valves now open farther and stay open longer so that it is able to suck in more air and to release burnt gases out faster. Acura is not the only company to do this. Other companies such as the Mitsubishi Innovative Valve Timing and Lift Electronic Control (MIVEC), Nissan's Continuous Variable Timing Control, and Toyota's Variable Valve and Lift with Intelligence (VVT-i). So far only Japanese automotive companies incorporated this technology into there engines. Before Honda introduced the VTEC in the Acura NSX super car back in 1991, cars were only able to produce horse power in the lower to midrange rpm or in the higher rpm range. Most normal everyday driving cars have camshafts the produce horse power in the lower to mid rpm range to make the car have a smoother idle. Racing cars such as NASCAR have racing cams that produce more horse power in the higher rpm range and causes the car to shake when at idle or low rpms because of the different kind of cam.

Another difference between the Mustang and the Integra is that the Mustang is rear wheel drive and the Integra is front wheel drive, many people have said that front wheel drive is better because with the engine over the wheels that pull the car, it will give the car better traction no matter what kind of weather whether it be dry, wet, or snowy conditions. After hearing about this, Ben Stewart of Popular Mechanics wrote an article on this called, "Push or Pull Which is Better: Front- or Rear-Wheel Drive?" They took three front wheel drive cars, a Ford Focus ZX4 ST, a Toyota Camry XLE V6, and a Pontiac Bonneville GXP V8, and compared it to three rear wheel drive cars, a Mercedes-Benz C230K Sport, an Infiniti G35 Leather, and a Chrysler 300C Hemi, and put them through a rigorous test. After the completion of the tests, the results were, "Neither front-wheel drive nor rear-wheel drive is really better than the other. Today's sophisticated traction and stability control systems are so good they can
