Engine type

8 CYLINDER V-Engine
It's an engine with eight cylinder piston where the cylinders share a common crankshaft and are arranged in a V configuration.

What is the 8 cylinder V-engine displacement: it is in a range between 2926 cc and 8135 cc in recent model line up powertrain.

How much is the power of the 8 cylinder V-engine: the power of the 8 cylinder V-engine is in a range from 125 bhp to 1160 bhp.

Which cars use 8 cylinder V-engine: in recent years several manufactures have been used the V8 engine for 3 main applications: premium, sport cars and lightweight trucks. 8 V engine is the American preferred engine for iconic giant pick-up.

What is the eight cylinder V angle: the majority of V8 engines use a V-angle of 90 degrees. This angle results in good engine balance and low vibrations. The downside is a larger powertrain body that makes the use of this configuration suitable only for longitudinal position and rear drive wheels traction.

V8 engines with a 60 degree V-angle were used in the 1996-1999 by Ford and in 2005-2011 by Volvo. The Ford engine used a 60 degree V-angle because it was based on a V6 engine with a 60 degree V-angle. Both the Ford and Volvo engines were used in transverse engine chassis, which were designed for a front-wheel-drive layout. To reduce the vibrations caused by the unbalanced 60 degree V-angle, Volvo's used a balance shaft and offset split crankpins.

The Rolls-Royce Meteorite tank engine also used a 60 degree V-angle, since it was derived from the 60 degree V12 Rolls-Royce Meteor which in turn was based on the famous Rolls-Royce Merlin V12 engine.

Most V8 engines fitted to road cars use a cross-plane crankshaft, since this configuration produces less vibration due to the perfect primary balance and secondary balance.

The rumbling exhaust sound produced by a typical cross-plane V8 engine is partly due to the uneven firing order within each of the two banks of four cylinders and with separate exhaust systems for each bank of cylinders, this uneven pulsing creates the legendary rumbling sound that is typically of V8 engines.
