3 Cylinder Engines - Explained

The inline 3 cylinder engine is similar to an inline 6, but cut in half. I3's make a good choice for small, compact, and cost-effective engines producing good fuel economy. The primary and secondary forces are balanced (vertically), though unlike an I6 there is a rocking moment front to back on the engine, as there is a plane imbalance. These engine are becoming more popular with demand for greater fuel economy rising. They've also seen some use with modern sports/race cars, used in the Nissan ZEOD RC as well as the BMW i8.

The World's Best Parallel Parker

Han Yue of China manages to park a mini with only 8 cm of clearance. You'd think that'd be about the wiggle room of the Mini when you make it come to an abrupt stop. Quite an impressive parking job! Hopefully the neighbors head home first.

Mercedes F1 Engine - Dominating 2014

The Mercedes F1 engine took a different approach, and their research and engineering has paid off well for the 2014 Formula 1 season. Their engine splits the turbocharger so the intake and exhaust portions are on opposite sides of the engine block, allowing for cooler air and shorter intake piping, reducing turbo lag. This also allows for aerodynamic improvements. Additionally, they've designed a unique exhaust to minimize aerodynamic drag and improve boost performance. Most of the ideas are relatively simple, but brilliantly executed, giving Mercedes the edge for the 2014 season.
