Kuàichē Motors (Also known as KM for short) is an American car brand that is owned by someone that is the descent of Chinese and Vietnamese. This is not a real car brand, it was just created for fun.
How engines are named: Engines are named with the letter followed by a 2 digit number. K engines are normal ones. KR ones are racing engines. E ones are electric ones. KTR ones are track racing ones, faster than KR ones.The number is for what type the engine is. For example, the KR01T is a turbocharged i6 meanwhile the KR02TT is a twin-turbo V6. The one that goes in front of the number is the modifications. T means turbo, Ti means turbo intercooled, TT means twin-turbo, TTi means twin-turbo intercooled, S means supercharged, ST means super and turbo, STi means super and turbo intercooled, STT means super and twin-turbo, STTi means super and twin-turbo intercooled. There is also bigger engine size that is represented by an E followed by the size in liters. For example, a KR03STiE5.0 means our 3rd KR series engine that is supercharged and turbocharged intercooled with a 5.0 liter engine.
