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 ...

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 ...

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.

Variable is good. From valve timing, valve lift, intake manifold, exhaust, ignition, fuel injection, turbocharging, cooling to lubrication, many things on today's engines can be variable. However, one ...

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 ...

BMW CS series was one of the masterpieces of the 70s. Few cars in history could deliver a combination of style, driving enjoyment and motorsport success like this car. On the road, the CS was highly ...

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 ...

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, ...

Continuously Variable Transmission is getting more and more popular on small to mid-size cars, eating the market share of manual and low-end automatic transmissions. In 2015, the world produced 11.3 ...

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 ...
