The video discusses the new Chevrolet Tracker, specifically its 1.2 turbo engine. The host explains how the engine works, comparing it to a naturally aspirated engine. The 1.2 turbo engine is equivalent to a 2.0 engine in terms of performance but is more economical.
The host visits the Chevrolet proving ground in Indaiatuba, Brazil, where they disassemble the engine to show its components, such as the engine block, pistons, and cylinders. They also explain the four phases of the engine: intake, compression, combustion, and exhaust.
The host then discusses the turbocharger, which uses exhaust gases to drive a turbine that compresses air, allowing more air to enter the engine. This results in better performance without increasing the engine's size.
The video also features the host test-driving the Chevrolet Tracker on the proving ground, reaching speeds of up to 160 km/h. They demonstrate the car's safety features, such as ABS and traction control, and praise the car's stability control system.
Overall, the video aims to educate viewers about the new Chevrolet Tracker's turbo engine and its benefits, while also showcasing the car's performance and safety features.
Here are the key facts extracted from the text:
1. The Chevrolet Tracker has a 1.2 turbo engine with 133 horsepower.
2. The 1.2 turbo engine does 3.5 km per liter on the highway with gasoline and 11.2 in the city.
3. The 1.2 turbo engine is equivalent to a 2.0 engine.
4. There is also a 1.0 turbo version with 116 horsepower.
5. The 1.0 turbo engine does 14.8 km per liter on gasoline on the highway and 13 in the city.
6. A turbo engine works by using exhaust gases to drive a turbine, which compresses air and forces it into the engine's cylinders.
7. The compressed air allows for a more efficient combustion process, resulting in more power and better fuel efficiency.
8. The turbo engine has four phases: firing, compression, combustion, and exhaust.
9. The engine block is made of aluminum, making it lighter than older engines.
10. The engine has a piston and connecting rod that move up and down to create a partial vacuum, which draws in air and fuel.
11. The air and fuel mixture is compressed by the piston, and then ignited by a spark plug, causing combustion.
12. The exhaust gases are released through the exhaust valve and into the turbocharger, which drives the turbine.
13. The turbocharger is connected to a compressor, which pushes air into the engine's cylinders.
14. The Chevrolet proving ground in Indaiatuba, São Paulo, has 17 tracks and is used for testing and development of Chevrolet vehicles.
15. The testing ground is equipped with a wet track for brake testing and other safety features.
16. The Tracker has six airbags as standard and stability control in all versions.
17. The stability control system is used to prevent the car from escaping on curves and to correct the car's trajectory in emergency situations.
18. The car's maximum speed is electronically limited to 187 km/h.
