It seems as though engine downsizing is the catch phrase of the last few years. Take an engine, shrink it and drop a turbo in and ba da bing, you've got a more efficient and sometimes even more powerful solution. Even though engine downsizing is popular, few have ventured as far as FEV Inc. With this new engine (pictured), appropriately called the Extremely Downsized Engine, FEV explores uncharted waters, going beyond tiny four-cylinder engines.
There are plenty of dynamometers in the world which are capable of helping tuners get the most from their engines. There aren't very many that allow the same type of tuning for hybrids, though. Hybrid drivetrains can be very complex pieces, featuring both the internal combustion engine of a normal passenger car and the motor, controller and batteries of an electric vehicle. To get the most out of each independent system, testing is becoming increasingly important.
