However, a number of experts believe that real-world fuel economy scores for turbocharged engines are negatively affected by the driver. Because these engines can make more power than naturally aspirated varieties, some drivers might be a little more aggressive with the gas pedal.
Are turbocharged cars good for fuel economy?
Some automakers say turbochargers offer high fuel economy and quick acceleration, the best of both worlds. Turbocharged vehicles allow automakers to keep power output high while they downsize engines for better fuel economy. But much of the mpg gain is lost when American drivers stomp the gas pedal and enjoy turbos’ high performance.
Is a turbo engine better than a regular engine?
In addition, consumers typically pay at least $1,000 more for a turbocharged engine. So, buyers not only pay more but are likely to get lower fuel economy than with a regular engine, the magazine concluded. Moreover, in some cases nonturbo engines can get higher fuel economy than turbocharged engines.
Is a turbo engine better for city-highway fuel economy?
The combined city-highway fuel economy for all of the vehicles came in lower than the EPA estimates by a few miles per gallon. In addition, consumers typically pay at least $1,000 more for a turbocharged engine. So, buyers not only pay more but are likely to get lower fuel economy than with a regular engine, the magazine concluded.
Will turbos continue to grow in popularity?
Turbos will still grow in popularity as automakers reduce gasoline engine sizes to meet increasingly stiff corporate average fuel economy standards, reaching an estimated 25 percent of new vehicles in North America in 2017, LMC Automotive predicts.
Why small turbo engines are not efficient?
Compared to a naturally aspirated engine, there is significantly more pressure in the combustion chamber for a turbocharged engine. With enough of this pressure, the air-fuel mixture could ignite on its own without the help of a spark plug, causing knock, which could destroy the engine.
Why are turboprop engines better than piston engines?
Turboprop engines are more fuel efficient 1, lighter for the same power, mechanically simpler and consequently more reliable. They are also slightly easier to operate (no need to fiddle with mixture) and burn cheaper fuel. As a result they replaced piston engines in all transport aircraft long ago.
Why do turbo engines make more sense in higher power settings?
@Jan Hudec: Turbo engines make more sense in the higher power settings simply because the airplanes with more powerful engines fly faster. With a piston engine, the power is constant over airspeed, so thrust goes with 1/v. Turbo machines can make better use of the kinetic energy of the airflow, so their thrust drops less with speed.
Why are small singles not turboprops?
As for why not all small singles are turboprops, the other answers have it; turboprops are less fuel efficient at the low altitudes small single typically fly at (they’re great for higher altitudes) and they’re a different beast to maintain.
Do small aircraft need a turboprop?
Small aircraft dont need the only advantage turboprop allows: more power to weight ratio.

What is a turbocharged car?
Turbos are taking the auto world by storm. Over one-third of newly manufactured light-duty vehicles come turbocharged. That means many people have a turbocharged vehicle and don’t even know it! Turbocharged vehicles pack a real punch, but with extra power comes extra responsibility.
Does a turbo save petrol?
Instead of adding a turbo to get more power out of the same engine, they are adding a turbo to get the same amount of power out of a smaller engine. The turbo itself doesn’t save gas, but using the smaller engine does.
How much fuel does a turbo save?
Turbo fuel saving efficiencies can be in the range of 8-10%, but be warned, put the foot down and these little engines will show you just how much power they have, and that they can burn just as much fuel as the big boys when at full throttle. We are well trained and have plenty of experience with turbo systems at Steve Sorensen Mechanical.
Does a turbo engine need more fuel?
Just know that a turbo engine will invariably need some extra fuel (use a “richer” air-fuel mixture) when the turbo is delivering pressurised air, which adds a slight consumption penalty to the turbo engine’s operation.
Is a turbo engine better than a naturally aspirated engine?
Thus trying to increase your vehicle speed with more aggressive throttle inputs will result in a turbocharged engine running an extra rich fuel mixture as compared to a naturally aspirated one. Thus real world efficiency is much lower in turbo engines.
Should you add a turbocharger to your car?
If anything, adding a turbocharger could produce worse gas mileage, not better. With a 54.5-mpg standard looming, car companies have stood that approach on its head. Instead of adding a turbo to get more power out of the same engine, they are adding a turbo to get the same amount of power out of a smaller engine.
Do turbo diesels use more fuel?
Diesel power efficiency is slightly higher, hence why diesels can get better fuel economy. Turbos are powered by the normally wasted energy that flows out of the exhaust pipe. A turbo is essentially two fans joined by a common shaft.
Can a diesel engine be turbocharged?
As with other engine types, turbocharging a diesel engine can significantly increase its efficiency and power output, especially when used in combination with an intercooler. Turbocharging of diesel engines began in the 1920s with large marine and stationary engines.
What are the benefits of a turbo engine?
Lower consumption: because you have a smaller capacity, but a higher power, you can drive in the city without having to overload the engine, so you will have a decent consumption. On the longer drives, the turbo helps you have a higher power at a lower speed, so you won’t have to drive the engine for much longer.
Is a turbocharged engine better than a non-turbo engine?
Turbo engines tend to have more problems in many cars, although there are turbocharged engines that are reliable. A turbocharged engine has more components than a naturally-aspirated (non-turbo) motor. These include an exhaust wastegate setup, intercooler, boost control system, vacuum pump and a more complicated crankcase ventilation (PCV).
Can you use premium gas on a turbo engine?
When you use premium gas on your turbo engine, it will provide more power compared to using regular gas. However, higher octane would not affect lower-compression engines. These engines will not completely burn the fuel leading to wasted gas. There will be no significant increase in performance when you use premium gas on a regular engine.
Is turbo less fuel efficient?
Are turbocharged engines more fuel-efficient than naturally aspirated engines? In theory, turbochargers can boost the efficiency of an internal combustion engine by anywhere from 10 to 30 percent.
Does a smaller turbo engine use less fuel?
If the engine can deliver enough power to cruise at freeway speeds without bringing the turbo into action, that requirement for extra fuel when boosting obviously doesn’t come into play, and in these conditions, the smaller turbo engine will use less fuel.
Is a non-turbo engine better?
The increased engine revolutions needed to produce adequate power can cause a non-turbo engine to experience lower fuel economy, especially at cruising speeds. Some of the most fuel efficient production engines are turbocharged diesel engines. Turbodiesel engines are capable of safely running a much higher turbocharger pressure setting.
Do turbocharged engines affect real-world fuel economy?
Some people will be quick to point out that some turbocharged engines don’t quite meet published fuel economy estimates provided by the government. There are a few reasons this could be the case. However, a number of experts believe that real-world fuel economy scores for turbocharged engines are negatively affected by the driver.
Are turboprops more efficient than Jets?
TAS has no dependence on air density. For short distances, turboprops are more fuel efficient than jets. On the longer flights, the jet (turbofan) engines win the race. Turbofan engines perform best at high altitudes. At medium and low altitudes, the turboprops are more efficient engines.
Do VW turbos need premium gas?
However, many Volkswagen vehicles, like the 2021 Volkswagen Tiguan and 2020 Volkswagen Jetta, are equipped with turbocharged engines. Turbocharged engines run best when fueled with high octane fuel, which is found in premium gas.
Why does turbo save fuel?
With a turbocharger, hard acceleration results in extremely high cylinder pressures. In response, the fuel system shoots in plenty of extra fuel – and there go your fuel savings.
Do turbos save gas?
Instead of adding a turbo to get more power out of the same engine, they are adding a turbo to get the same amount of power out of a smaller engine. The turbo itself doesn’t save gas, but using the smaller engine does. Turbos are often used together with direct injection.
Do turbocharged engines burn more fuel?
Consumer Reports, for example, concluded that downsized, turbocharged engines typically achieve worse mileage than larger engines without turbochargers. In their tests, Ecoboost Ford Fusions using turbocharged, four-cylinder engines burned more fuel than their larger, naturally-aspirated counterparts.
Why do some cars use turbochargers?
While once limited to high-end performance models, many automakers nowadays use turbochargers to eke out more power from otherwise tame engines. One example is the Toyota Raize, which packs a relatively minuscule 1.0-liter, three-cylinder engine. Toyota managed to squeeze 96 horsepower out of that tiny engine.
What is a turbo and how does it work?
Turbos are often used together with direct injection. Direct injection shoots computer-controlled squirts of fuel into the combustion chamber inside the engine cylinders. The high pressure and precise control produce more thorough burning. The user benefits are more power and lower emissions from a given amount of fuel.
What fuel is best for turbo?
Do turbo cars need premium gas? Not all turbocharged cars need premium gas, but it’s a more common requirement among turbos than other kinds of engines, thanks to the way these engines work. The name turbo comes from the turbine these engines use to inject more air into the air-fuel mixture in the combustion chamber.
Which gas is best for a turbocharged engine?
Turbocharged engines will work best with premium gas. Since such vehicles are designed with high-performance parts, premium gas helps to maintain their quality. To get the most out of your turbo engine, premium gas is the best bet. The high-octane levels help the systems run seamlessly and offer efficient conversions.
Why is premium gas a good choice for a turbo engine?
Premium gas is suitable for turbo engines because it is hard to ignite since it has high octane levels. It is also ideal for running the engine at greater compression rations before detonation. By increasing the compression ratio, a turbocharger boosts the amount of gas in the cylinder, which results in a more efficient engine .
Do turbo engines use high octane gas?
Turbo engines are designed for use with high octane gas. These are suitable for cars with engines that operate at higher compression ratios, allowing them to completely consume the fuel’s energy. Turbocharged engines have high compression ratios since they are designed for high performance.
What is a good fuel mixture for a car?
The ratio of this mixture affects your fuel economy, performance, reliability, or even if your car runs at all. The scientifically “perfect” mixture for normal petrol is 14.7:1, that is 14.7 times the mass of air to fuel. However, that doesn’t mean a car should run at that.
