When it comes to cars the raw horsepower is everything. Without that it is as good as riding a bicycle. A V4 or a V6 is definitely no match for the brute force of a V8. And every time you go past a V8, rather a V8 passes you by; you wonder why you opted for a beauty queen over smart and smooth performance.
Not that a six cylinder engine is worse than an eight cylinder, but if you're a power addict, a V6 might be a dampener. But not any longer! A new technology is in the market that has been designed to combine the feeling of power with fuel efficiency-a light weight six cylinder engine performing like an eight cylinder and simultaneously downsizing on the usage of gas.
Wondering how does that works? This new engine combines turbo charging, direct fuel injection and variable timing in the valves that control fuel and exhaust flow to make this a reality. In other words, the engine uses the turbo charging to let more air flow to the fuel burning chamber.
The variable valve then times it accordingly to flush out the exhaust gas completely from the fuel chamber after combustion has occurred. And finally the direct fuel injector ensures that any knocking issues are taken care of. And less fuel consumed would result in considerably lower emission of carbon monoxide, which means relatively less pollution.
Do not mistake for a tamed version of an eight cylinder done in a hotchpotch manner. It is a known fact that supercharging a six or for that matter even a four cylinder engine to the power levels of an eight cylinder engine would only add more to the existing complexity of the design of the engine and would weigh bulkier than needed. Thankfully, this new hybrid technology has been designed in such a way that it maintains the light weight of a V6 and yet manages to perform powerfully.
What is essentially going to be a matter of debate here is why go for a V8's power when a V6 or a V4 is equally manageable and meets the needs of the masses. Unless one likes the adrenalin rush of driving a powerful brute, a V8 is not something what one would buy, besides the fact that a V8 is expensive than a four or a six.
But with rising fuel prices and the threat of over pollution looming large (oh yes, the US is the highest global emitter of the greenhouse gases and that includes automobile emissions), alternative fuels and hybrid engines become the need of the hour.
This new technology introduced by motor giant Ford, has its eyes more on being fuel efficient than matching any performance levels. That it does, is just an added plus point of this engine. The slightly expensive price tag may make this multi displacement systems may not go down too well with many.
What may work to its advantage is the fact that it eliminates the gas guzzler effect of a V8 but gives a similar performance and yet retains the compactness of a six cylinder.
