While manual transmissions are still available in today’s market, they face an uncertain future, with their sales comprising less than 5% of total car sales worldwide. In a previous article, we discussed BMW’s perspective on the future of manual transmissions, which are slowly being phased out in favor of automatics.
Yet, despite their declining popularity, manual transmissions still have a dedicated group of enthusiasts who passionately defend them. The question remains: are their arguments convincing enough to justify car manufacturers continuing to offer manual gearboxes?
Manual vs. Automatic: How They Work
Let’s begin by understanding how a manual transmission functions.
The engine of a car cannot be directly connected to the wheels, as the engine operates at much higher speeds than the wheels can handle. Typically, gasoline engines spin at speeds between 600 and 6,500 revolutions per minute (RPM), while the wheels rotate at speeds between zero and 1,500 RPM.
By using the gears in a manual transmission, the engine’s high speed is reduced to match the slower rotation of the wheels. This requires multiple gear ratios, as one gear alone cannot suit all driving conditions.
In cars equipped with a manual transmission, the driver must select the appropriate gear, balancing engine speed with wheel speed.
Manual vs. Automatic: Understanding the Automatic Gearbox
On the other hand, an automatic transmission features a “torque converter,” which continually connects the engine and the gearbox. Unlike manual transmissions, which use a clutch to engage gears, the torque converter relies on hydraulic fluid to transmit the engine’s power to the gearbox. This fluid movement allows the wheels to select the correct gear without the driver’s input.
Manual vs. Automatic: A Comparison
Driving enthusiasts often revel in the art of shifting gears manually, but engaging the clutch, selecting gears, and releasing the clutch can be a tedious process, especially for professional drivers like those in taxis or buses. This is where automatic transmissions come into play, offering ease and convenience.
However, the Manual vs. Automatic debate continues to spark discussion, with key factors often being price, fuel efficiency, maintenance costs, and driving experience.
Price In general, cars equipped with manual transmissions tend to be cheaper than their automatic counterparts. While price differences vary by model, some manual cars can be up to $1,000 less than those with automatic gearboxes. However, there are cases where manufacturers price both versions equally.
Fuel Efficiency In the past, manual transmissions were known for their superior fuel efficiency compared to automatics. However, advancements in automotive technology have closed that gap, with many modern automatic cars now consuming less fuel. For instance, the 2014 Ford Focus uses 7.58 liters per 100 kilometers with an automatic transmission, compared to 7.84 liters per 100 kilometers with a manual.
Maintenance Costs If you ask a mechanic, they’ll likely tell you that manual transmissions are easier and cheaper to repair than automatics. Manual cars generally require less maintenance, while automatic transmissions have more components that demand attention, such as fluid changes and repairs, which can drive up costs.
Driving Experience and Control Automatic transmissions are designed to select the best gear for any situation, but they sometimes misjudge and select a higher gear than needed, especially when the accelerator is pressed too hard, which can waste engine power. In contrast, manual transmissions give the driver full control, allowing for more precise handling, especially when more torque is needed.
Manual vs. Automatic: Which Is Better?
Ultimately, the decision between manual and automatic transmission comes down to personal preference. Automatic transmissions are easier to use and more comfortable for everyday driving, particularly in traffic jams, where frequent gear changes can become tiresome. Many car manufacturers are now offering semi-automatic options, reflecting the shift in consumer demand.
On the flip side, manual transmissions offer a cheaper option and a more engaged driving experience. The sense of control provided by manual gearboxes is hard to match, and for some, the simple joy of shifting gears is reason enough to stick with a manual car.
