What does SC mean in cars?

SC in cars stands for the launch control function, which is a feature available in Porsche vehicles. Porsche is a German automobile manufacturer that produces sedans, sports cars, and SUVs. Porsche's sports car lineup includes the 911 and 718, while its sedans include the Panamera and Taycan, and its SUVs are the Macan and Cayenne. The Porsche Cayenne is equipped with three types of engines: a 3.0-liter turbocharged engine, a 2.9-liter twin-turbocharged engine, and a 4.0-liter twin-turbocharged engine. Below is a detailed introduction: 1. The 3.0-liter turbocharged engine delivers 340 horsepower and a maximum torque of 450 Nm. This engine reaches its peak power at 5300 to 6400 rpm and its maximum torque at 1340 to 5300 rpm. It features direct fuel injection and an aluminum alloy cylinder head and block. 2. The 4.0-liter twin-turbocharged engine produces 550 horsepower and a maximum torque of 770 Nm. Its peak power is achieved at 5750 to 6000 rpm, and maximum torque is available from 2000 to 4500 rpm. 3. The 2.9-liter twin-turbocharged engine generates 440 horsepower and a maximum torque of 550 Nm. This engine reaches peak power at 5700 to 6600 rpm and maximum torque at 1800 to 5500 rpm. It also features direct fuel injection and an aluminum alloy cylinder head and block.
I usually enjoy studying automotive mechanics, and SC in cars typically stands for Supercharger. This device is driven directly by the engine crankshaft to compress air, forcing more air into the combustion chamber—essentially giving the engine a shot of Red Bull. Compared to turbocharging, the biggest advantage of a supercharger is its lightning-fast power response—step on the gas, and you get immediate thrust without any turbo lag. However, the trade-off is that it siphons off 15%-20% of the engine's power and comes with a noticeable whirring noise. I once saw a case on a tuning forum where a car enthusiast installed a Rotrex supercharger kit on a Mustang, boosting horsepower from 300 to 450. But three months later, the crankshaft snapped—proof that modifications should be done within one's limits. Nowadays, many performance cars come factory-equipped with superchargers, like the clever design of the new Audi S5's 3.0T engine paired with an electronically controlled supercharger.
