What is a V8 car?
1 Answers
V8 is not a brand of car. V8 generally refers to the layout of the engine. Vehicles equipped with a V8 engine will have a V8 logo on the body, indicating that the car has an 8-cylinder engine, which is different from other vehicles. The V8 engine is one of the cylinder arrangement types of internal combustion engines. It is generally used in mid-to-high-end vehicles. The eight cylinders are divided into two groups, with four in each group, arranged in a V-shape. It is the most common engine structure in high-level automotive sports. The principle of the V8 engine is the same as that of other engines, with V8 representing the arrangement and number of engine cylinders. Common cylinder numbers for car engines include 3-cylinder, 4-cylinder, 6-cylinder, 8-cylinder, 10-cylinder, and 12-cylinder. Sedan models equipped with V8 engines include the BMW 7 Series, Mustang, Maybach, Porsche Panamera, Ferrari 488, etc. SUV models include the Porsche Cayenne, Mercedes-Benz GLE-Class, Cadillac Escalade, Bentley Bentayga, Mercedes-AMG G-Class, Lamborghini Urus, Lexus LX, Mercedes-Benz GLS-Class, Range Rover Sport, BMW X7, etc. There are two different types of V8 engines due to differences in the crankshaft. One is the cross-plane V8 structure, where each crank in a group (four per group) is at a 90° angle to the previous one, forming a cross structure when viewed from one end of the crankshaft. This cross-plane can achieve excellent balance but requires heavy counterweights. The other is the flat-plane structure, which does not need counterweights, resulting in a lighter crankshaft with lower inertia, allowing for higher RPM and acceleration.
