Eight Things About TURBOs You (Probably) Never Knew

Garrett Motion has been producing turbochargers since the 1950s. Since that time, the technology has become synonymous with high-end performance in vehicles, but turbos are also now commonly used by automakers around the globe to improve energy efficiency through engine downsizing. By using a turbo, engine manufacturers can downsize the cylinder capacity of their engines to reap the fuel economy and emissions benefits of the lighter weight, smaller engine, without sacrificing performance

These benefits are why, in its recent turbo forecast, Garrett predicted that 200 million cars with turbocharged engines will be produced during the next five years.  By 2021, 48 percent of all new vehicles are expected to have a turbo fitted.

Here are some thing you may or may not know about the turbocharger that is giving your car that extra boost!

 Fuel Frugality: By integrating a turbocharger with a downsized engine, automakers can improve fuel efficiency by as much as 40 percent in diesel applications and 20 percent in gas applications as compared to a larger naturally-aspirated gas engine with similar output performance



You Spin Me Right Round (Like a Turbo, Baby): The turbine in a typical car turbocharger has to spin incredibly quickly. While your car’s engine revs, at cruise, at around 2,000 rpm, a turbo’s turbine can reach rotational speeds of more than 280,000 rpm.



Fine Engineering: The required level of accuracy when designing and manufacturing the size of a turbo’s components is, in some cases, smaller than the width of a human hair.



Toasty Turbines: Turbos operate in extreme heat, in excess of 1050 °C in gasoline engines. Even in diesel engines they run hotter than the temperature of molten lava.



Going Green: By 2020 Garrett expects that 7 percent of all cars on the road will be hybrids – at least 2 percent of which will be turbocharged.



Driving Demand: In order to meet huge demand from the world’s automakers, Garrett launches on average 100 new turbo applications every year, and has more than 500 programs in its product development pipeline at any given time.



In It For The Long Haul: Turbocharger performance is integral to engine design and performance, which is why reliability is extremely important. Cars using Garrett turbochargers have won the 24hrs of Le Mans endurance race every year for the past 20 years.



Second Life, First In Quality: Garrett Motion is the company’s independent aftermarket brand which sells replacement turbos. A recent study commissioned by Garrett and conducted by an independent laboratory in the U.K. determined replacement turbos like Garrett products can have as much as 40 percent better torque and emit as much as 28 percent less nitrous oxides than copy replacement parts not built to the exacting original equipment specifications of your vehicle.
