After memorizing the shifting of gear levers between religions, just started practicing moving forward, of course in the close track area, not on the highway. In addition to novice drivers do not have a SIM, parking areas or roads in housing are more quiet and safe for driving practice.
Ideally, the transmission would be so flexible in its ratios that the engine could always run at its single, best-performance rpm value. That is the idea behind the continuously variable transmission (CVT).
The manual transmission is on the endangered species list. Every year fewer and fewer cars are offered with a clutch and a shifter. Why? Americans just don’t want to be bothered with the chore of working a clutch with their left foot and shifting with their right. And sports car manufacturers are the worst offenders when it comes to quitting on the stick shift. Because the newest computer-controlled automatics can shift more quickly than any human can, engineers see the manual transmission as outdated.
The brake and accelerator pedals are pretty simple – press the brake to slow down (the firmer you press it, the quicker you’ll lose speed), while using the accelerator increases the engine’s revs and causes you to speed up (the firmer you press it, the quicker you will speed up).
The car is faster since there is no interruption in power, the ride is smoother since it’s all but impossible to pinpoint the moment of the gear change, and fuel economy is better because there is no power lost to inefficient shifts.
t’s worth noting that some cars with dual-clutch automatics offer a manual shifting mode, usually via steering wheel-mounted paddle shifters, but the experience is not the same. Some performance enthusiasts may bemoan the loss of the ”row-it-yourself” experience, since manually shifting is an enjoyable skill to practice and perfect, but if speed is the ultimate goal, it’s hard to argue with the results of an automated manual transmission.
Cars need transmissions because of the physics of the gasoline engine. First, any engine has a redline — a maximum rpm value above which the engine cannot go without exploding. Second, if you have read How Horsepower Works, then you know that engines have narrow rpm ranges where horsepower and torque are at their maximum. For example, an engine might produce its maximum horsepower at 5,500 rpm. The transmission allows the gear ratio between the engine and the drive wheels to change as the car speeds up and slows down. You shift gears so the engine can stay below the redline and near the rpm band of its best performance.
