For those who always have the urge to go fast, the first thing to check is the engine. If the engine is bigger, then probably it will be more powerful. A bigger engine on the same size car will make it go a bit faster than a smaller engine. Next, check how the engine is aspirated. A turbo will add some power and speed as well. Although turbocharged engines are preferred by some, others prefer to use naturally aspirated engines. Regardless of what you keep under the hood, just keep in mind that the faster your car can go, the more efficient your brakes need to be. So before you step on the gas, make sure you know the capabilities of the brake pedal too.
