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 ...

2002 series was probably the most important model in BMW's history. In the early 60s, although small cars like Isetta, 600 and 700 kept the Munich company alive, its image was mushy and financial ...

The advantage of turbocharging is obvious - instead of wasting thermal energy through exhaust, we can make use of such energy to increase engine power. By directing exhaust gas to drive a turbine, ...

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 ...

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 ...

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, ...

Skyline GT-R was the first Japanese performance car truly beating the best European sports cars by dynamics rather than value for money. From 1989 to 2002, three generations of GT-R got the highest ...

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 ...

The use of twin-turbocharger is a question of both efficiency and packaging. A small engine is of course better to use a single turbo, because it does not produce sufficient exhaust gas to drive 2 ...

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 ...

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 ...
