Modern automobile industries strive to develop new technology that improve standards of living and offer world class solutions to vehicle management. Contemporary vehicle upgrades include mechanisms that mitigate lapses made on previous version and a few of the necessary upgrades involve vehicle weight which has significant effect on speed and control, fuel economy and horsepower.

Everyone loves fast cars; this of course has its downsides in relation to fuel economy. The trend however favors turbocharged engines which greatly boost horsepower, but what is the effect of this technology on fuel economy?


The turbocharger requires extra gas since it doesn’t produce its own power. It is simply a turbine which sits under the vehicle hoody, it compresses free air that goes into the engine. The density of the air allows air molecules inside each cylinder. Since the turbocharger is partly controlled by the exhaust, the emission of the exhaust spins its turbine. Acceleration generally involves the absorption of compressed air and injection of extra fuel in the engine to build up more horsepower. SUVs and other large vehicles are also built with turbocharged engines. This further proves the increased craving for more horsepower by individuals and companies.

Formally turbochargers were used to boost the speed on vehicles with less than adequate power, this was a form of upgrade which was used to sustain these old model cars in the market ( these include the Oldsmobile F-85 from the 60’s, with the advancement in technology turbochargers were used to boost already fast car into super fast. The earlier manufactured turbochargers had a few lapses; they were bigger in size and required extra power also there was a significant lag phase between the time the driver floors the pedal and the time the turbocharger actually kicks in. this was called “Turbo lag”.


The extremely large turbochargers have phased out, giving way to much smaller ones like those on the new ford focus and Fiesta ST which uses 1.0-liter three cylinder engine. The turbochargers only produce extra power when it is needed so the driver can afford to cruise without applying turbo. The best part is that the new turbochargers build speed far quicker than the larger older ones and consume far lesser fuel, even though the results are often unstable. Some turbocharged cars deliver awesome gas mileage in EPA testing while others are still a drag and still dwindle in numbers.

Automobile manufacturing companies often optimize their vehicles to meet up with a tenth of a mile per-gallon EPA testing in order to boost the vehicle’s fuel economy ratings. This would make the vehicle model a success and is sure to drive sales.


Turbochargers have become quite popular, they come in trucks like the ford F-150 which features two turbocharged V6 with 2.7 & 3.5 liter. It makes an outstanding towing and hauling machine.

Smaller car make even more power at a relatively lower rpm so they are much more at ease while cruising. With a modern turbocharged engine you get a very fast and powerful machine with a very reasonable fuel economy rating.
