Ducati has announced it will introduce new engine technology that will boost power and torque, improve fuel economy, reduce emissions and won’t affect servicing intervals. Ducati Testastretta engine ...

The language of import performance can be strange. Sometimes it's a verbal stew of numbers and letters--RX-8, NSX, and MR2, for example--that seem randomly tossed together. At other times it adopts ...

There is so much going on with internal combustion engines (ICEs) these days, it can give you a headache just reading about them. That's why we do the research for you and then cram it into bite-size ...

Once upon a time, picking a cam for a given engine combo was all about compromise: improve top-end power at the expense of low-end torque, run well at wide-open throttle but sacrifice idle stability ...

Somewhere there's a perfect balance between peak horsepower, low-speed response, reduced emissions, and something you can afford. Variable valve timing and lift have done their part in getting us all ...

The tough guy in you says to stab that cam in retarded a few degrees for maximum top-end horsepower, while your more practical alter ego suggests advancing it a hair for improved low-end torque and ...

The inlet and exhaust valve timing of a piston engine plays a large role in engine performance. Many modern automotive engines have some sort of variable valve timing, but the valves are still ...
