Are Diesel or Hybrid Cars For You? By Brenda Williams At Isnare.com Ezine Articles

While everyone is looking to a greener planet, car makers are also doing their best to come out with newer environmentally friendly models. Technological advancement is what is propelling the automotive industry to come out with fuel efficient and zero emission engines, not forgetting the need to search for replaceable energy source as the new alternative power source.

Diesel has been a long time favorite for fuel efficient drivers. With the high compression engine and diesel having higher energy content, it has a potential of pitting against gasoline vehicles in terms of power over efficiency. This can be seen in Audi R10 being a diesel powered car winning the Le Mans 24 hour endurance race consecutively thanks to not having to pop in the pit stop to refuel as frequently as other competitors. Considering the smelly diesel puffs from buses ages ago, it might not be a good choice as an environmentally friendly car.

When we look at hybrid vehicle, we can only look at vehicles with two power sources being slapped together as one. Usually a combination of gasoline engine with an electric motor’s assistance. The green part of a hybrid vehicle is that the car is smart enough to switch off the gasoline engine and make use of the electric motor at certain time, reducing the petrol used. Although the theory sounds flawless, actual efficient driving on a hybrid requires a unique driving style in order to get more miles out of the engine. The promising hybrid vehicles are the topic of discussion these days. Already out there some of the hybrid vehicles such as popular Toyota Prius, Honda Civic Hybrid, and numerous other common production cars with a ‘Hybrid’ or ‘H’ emblem stuck to the boot. The wonder of a hybrid is the energy balancing capability of both motors present in the car itself. Say for instance the car will use the petrol engine to propel the car from standstill and to a stage where the car is cruising, the electric motor will be driving the car, putting the pistons to rest. This intelligent concept also includes the regenerative braking capability that charges up the car’s battery so that the electric motor can use it for cruising.

On the other hand, diesel powered vehicles still works the same as a combustion engine. The only difference is newer diesel engines delivers higher power and torque rating thanks to technologies such as common rail diesel engines. With torque being the strong point of diesel cars, it needs a low rev to get to the highest torque compared to petrol engines. Take the Mercedes models for an example, with a CDI engine, some with smaller capacity diesel engine outperforms higher capacity petrol cars. The longer cruise range and low emission green engine makes it a selling point too.

Speaking of which, since hybrid vehicles are powered by a combination of electric motor and gasoline engine, why not a turbocharged common rail diesel engine slapped with an electric motor side by side? Diesel hybrids might be on the way soon once car manufacturers figure out how to balance the heavy gadget filled common rail diesel engine together with heavy battery packs to create a better hybrid. As the hybrid makers say, all they need is torque to move the vehicle from standstill – so why not use a diesel engine?
