As shown in the picture, straight-6 engine is simply a pair of 3-cylinder engines mated together symmetrically, thus piston 1 is always in the same position as piston 6, piston 2 the same as piston 5.

Manual transmission might be almost dead in the USA – only 4 percent of all new cars sold there are equipped with stick-shift – but in the rest of the world it is still the choice of the majority. For ...

There was a story behind the name "Dino" and the V6 engine. Alfredino Ferrari, the only son of Enzo Ferrari, suggested his father to develop a V6 racing engine for Formula 2 in the early 60s. Although ...

Whenever I mention Subaru, the images of the first generation Impreza WRX always flash in my mind. Undoubtedly, the first generation WRX was the symbol of Subaru as well as one of the iconic cars in ...

A refined engine should be smooth running, free of vibration and quiet. These qualities also help the engine to spin freer at high rpm, lifting red line hence power output. Engine smoothness depends ...

All cars need energy for propulsion. When they decelerate and stop, the energy is wasted in braking. Why not recapture the braking energy, store it and use it for acceleration later on? That is ...

First introduced by Mercedes 300SL in 1954, tuned intake manifold is not exactly a new technology. It is discussed here just because its principle is useful to our further study of variable intake ...

It would be good to have a linear, predictable steering response, but sometimes varying the steering ratio could enhance the driving experience. For example, when cruising on highway we want the ...

6 cylinder engines, no matter inline-6 or V6, are inherently smoother than 4-cylinder inline engines because all the first order and second order forces can be balanced. However, most small cars do ...

As many people know, mechanical superchargers are good for low-end output but short of high-end efficiency, while exhaust turbochargers work strongly at high rev but reluctantly at low rev. For ...

Steering is very important to a car because it is the interface that the driver touches most. What makes a car's steering better than another? It is usually judged by several factors: directness, ...
