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 ...

Variable cycle engine design embodies a transformative approach in aero‐propulsion, enabling engines to adapt their thermodynamic cycle to meet diverse operational demands, from fuel efficiency to ...

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 ...

Mazda’s implementation of the Miller-cycle engine in their production vehicles, starting with the 1995 Xedos 9, marked a significant shift in automotive powertrain design. The unique 2.25-litre V6 ...

Intake, compression, power, then exhaust. Every 4-stroke engine ever made – about 80% of all engines currently in existence – function on this principle – even rotary engines. But now, Porsche has ...

Rotary engines have an aura of cool. In games of Top Trumps, the V12 might have been king, but a rotary was a joker, a wild card. A lack of mainstream success no doubt contributes; there are reasons ...

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 ...

The Mazda CX-90 feels like a bona fide luxury SUV, but the company's current upmarket push isn't its first. At one time, Mazda was actually going to launch its own luxury sub-brand, and it would bring ...
