After multi-valve technology became standard in engine design, Variable Valve Timing becomes the next step to enhance engine output, no matter power or torque. As you know, valves activate the ...

Ferrari's first generation mid-engined sports car was Dino 206GT / 246GT. It was an excellent driver's car, but too small and too slow to be called exotic. During the whole 1970s and 1980s, the world ...

When I started watching cars in the mid-1980s, most cars on the road were still fed by carburettors, including the wildest supercars like Lamborghini Countach QV and Aston Martin Zagato. Carburettors ...

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 ...

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 ...

British car maker Rover introduced its own VVT system called VVC (Variable Valve Control) on MGF in 1995. Many experts regarded it as the best VVT system at the time. The VVC can continuously vary the ...

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, ...

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 ...

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, ...

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 ...

Ram air intake is perhaps the simplest kind of forced induction. When the car is travelling at speed, air will be forced into the intake manifold through the ram air inlet which usually locates at the ...

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 ...
