Is Turbocharging Represented by T or L?

[Lilian]

Turbocharging is represented by T. Below is an introduction to turbochargers: 1. Advantages: The greatest advantage of a turbocharger is that it can significantly increase the engine's power and torque without enlarging the engine displacement. After installing a turbocharger, the engine's power and torque can increase by 20% to 30%. 2. Disadvantages: The drawback of a turbocharger is lag, meaning that due to the inertia of the impeller, there is a delayed response to sudden changes in throttle input, causing the engine to delay in increasing or decreasing power output. For cars that need sudden acceleration or overtaking, there might be a momentary feeling of insufficient power.

Last time when I got my car repaired, the mechanic explained it clearly - turbocharged engines are mostly labeled with 'T', like Volkswagen's 1.4T or Ford's 1.5T. But be careful, some cars have badges like 280TSI or 330TFSI on the rear, which actually indicate turbocharging. Naturally aspirated engines are marked with 'L', such as the old Toyota 2.0L. Once when I helped a friend inspect a used car, I immediately knew it was turbocharged when I saw '1.8T' on the engine cover, while '2.0L' would mean naturally aspirated. Hybrid models are more complicated - for example, Lexus' 2.5L hybrid still uses a naturally aspirated engine principle despite having electric components.

I remember researching this when helping my cousin buy a car. Nowadays, 90% of new cars on the market use 'T' as the turbo identifier. American brands like Buick's 28T represents a 2.0T, while German brands like the Mercedes C200 don't write anything after the number in the badge but actually use turbo engines. There are exceptions though - Mitsubishi's older 2.4L supercharged models were labeled MIVEC, so you'd need to check the technical specifications. Here's a trick: popping the hood to look for the turbo cooling pipe is the most reliable method - that silver metal tube wrapped in heat insulation material is a dead giveaway.

Just two days ago, there was still a debate about this in the car enthusiasts' group. The 'T' in turbocharging stands for the first letter of 'Turbo,' and manufacturers love to display it on the rear of their cars. Examples like the Hyundai Fista 1.6T and the Lynk & Co 03's 2.0TD follow this pattern. The 'L' in naturally aspirated engines actually represents the displacement unit, but it's now used to distinguish them from turbocharged cars. Nowadays, even 1.0T turbocharged cars are common, outperforming the old Santana 1.8L. Mechanics often see owners of 'T' cars, and their maintenance costs are at least 30% higher.
