In an era where turbocharged engines make up the bulk of internal combustion engines seen in new cars today, naturally aspirated engines are still highly sought after, especially among enthusiasts of older generation sports cars. With a more direct injection than a forced induction engine, the absence of a turbo lag is usually the main reason why people like naturally aspirated engines. However, are there also implications related to fuel economy, torque figures, power output, and maintenance? This article will give an overview of the advantages and discuss why naturally aspirated engines are still sought after by some drivers today.
Simplicity & Durability
One great advantage of a naturally aspirated engine is its simplicity and durability. Since these types of engines don’t require any additional components (like turbos or superchargers), they tend to be more reliable and easier to maintain than those with forced induction systems. Plus, because natural aspiration eliminates the need for extra parts, these engines also tend to be lighter and provide more power per pound than others.
Cost Effective to Maintain
Another major advantage of naturally aspirated engines is cost-effectiveness. In most cases, these cars require fewer maintenance visits due to their simpler designs which results in lower repair bills over time. Moreover, since a bigger engine requires more fuel, cars with smaller naturally aspirated ones can save the driver money at the pump as well!
Smoother & More Refined
Finally, many people prefer the smoother driving experience provided by naturally aspirated engines over those designed for forced induction systems. The lack of turbo lag—the delay experienced by some vehicles between pressing on the gas pedal and accessing power—can result in a more consistent drive with no sudden bursts as seen from some turbocharged vehicles.
Naturally aspirated engines provide many benefits for car owners looking for a quality ride without breaking the bank or lacking in performance capabilities. With improved durability, weight savings, cost savings, plus an arguably smoother ride, there are plenty of reasons why these types of cars remain popular choices today.
