Whether we're talking about vehicles with two or four wheels, a primary goal of engineers is to wring out as much power from each unit of displacement for every engine they make. This keeps weight ...

For decades, engineers have used small-displacement engines to prove that raw capacity is not the only path to victory. By pairing compact cylinders with clever breathing, high revs, and forced ...

While there have been some iconic big-block engines over the last few decades, it's difficult to argue with the success of the small-block engine. Small-block engines not only weigh less — allowing ...

General Motors may not be building a bike engine, but this two-stroke concept has real potential for motorcycle engineering. General Motors and two-stroke engines aren’t exactly two things you expect ...
