Sports cars and high performance cars are distinct from most other vehicles, owing to their power, speed, and purring sound. They achieve these features because of their special engines - the V-Engines.Why V-Engines are the Ideal Choice for Sportscars The V-engine is an internal combustion engine configuration, whereby the piston alignment takes the shape of a “V” when viewed along the positioning of the crankshaft. The anatomy of a sportscars engine offers many benefits, which make the engines ideal for powering sports cars. Some of these benefits include:1. Smaller Engine SizeV-engines are more compact than the conventional inline engine configurations, owing to their comparatively shorter crankshafts. The advantages of reduced engine length, weight, and height include:
2. Smooth power delivery V-engines offer a higher number of power strokes per revolution, as compared to other engine configurations. As a result, the engines' power delivery is much smoother, especially at low RPM. 3. Reciprocating masses The V-engine configuration offers an increased number of cylinders in a smaller package. An increase in the number of cylinders lowers the mass of reciprocating components in an engine, including pistons and valves, for a given displacement. Therefore, V-engines are able to produce more power for a given displacement, due to the higher RPM that results from the lowering of the reciprocating masses. 4. Improved Gas FlowThe higher number of cylinders in a V-engine for a given displacement creates additional room within the cylinder heads for valves. In effect, the gas flow in the intake manifold is improved, and there is low restriction for exhaust and intake gases.The Anatomy of a Sportscars Engine - What produces the distinct Purr?V-engines have an irregular firing order. Each time a cylinder fires, it creates an exhaust pulse. Having two cylinders firing on the same side, in a given sequence, creates two opposing exhaust pulses, which results in an unevenly high exhaust pressure and loud noise. The purr is created when this noise escapes through the tailpipe.
