What does 8t mean?

T stands for Turbo, which means turbocharging. A turbocharger is essentially an air compressor that utilizes the exhaust gases from the engine as power to drive the turbine in the turbine housing (located in the exhaust passage). The turbine, in turn, drives the coaxial impeller (located in the intake passage), which compresses the fresh air delivered by the air filter pipeline and then sends it into the cylinders. Expansion: When the engine speed increases, the exhaust gas discharge speed and turbine speed also increase simultaneously, thereby enhancing the degree of air compression. Consequently, the engine's air intake increases accordingly, allowing for an increase in the engine's output power. The greatest advantage of turbocharging is that it can significantly boost the engine's power without increasing the engine displacement.
Last time I was chatting about cars with a friend, he asked me what '8t' means. Actually, in the automotive world, '8t' refers to an 8-speed automatic transmission, which means the transmission has eight forward gears that can automatically adjust gear ratios at different speeds for smoother shifting and better fuel efficiency. I've driven quite a few cars equipped with this type of transmission, such as some Japanese or German brands, and you can barely feel any jerking during acceleration. Especially during highway cruising, the engine runs at lower RPMs, saving fuel – over a year, this can add up to significant savings on gas. However, its structure is a bit more complex, so it's important to find a reliable mechanic for maintenance to avoid potential repair hassles. Overall, the 8t transmission makes driving more relaxed and comfortable, particularly suitable for those who frequently take long trips or prioritize fuel economy. When you see the '8t' badge while car shopping, it's generally a good sign.
