The car industry is currently undergoing a green revolution, with a number of exciting new technologies vying to challenge the predominance of petrol and diesel and put an end to the internal combustion engine’s negative effects on the environment.
For many years now, private cars have been a favourite target of environmental campaigners, mainly due to the harmful emissions that all internal-combustion engines release into the atmosphere. Their effect was illustrated starkly several times in the 1970s when ‘car-mad’ cities like Los Angeles and London were frequently shrouded in a thick, polluting smog. Car manufacturers have been working on improving their products’ environmental credentials for quite some time now. The most significant developments of the last quarter of a century include the rollout of unleaded fuel, as well as the mandatory fitment of catalytic converters, which remove many of the most harmful elements of vehicle exhaust fumes, to all new cars. But as the 21st century dawned, talk of diminishing oil supplies and the ongoing threat of global warming has incentivised both carmakers and governments to accelerate development of the technologies that will one day take over completely from those in the cars for sale today, which remain dependent on fossil fuels.

Hybrid cars have well and truly entered the consciousness of the car-buying public in the last few years, as ‘greener motoring’ has become a hot topic. We have all heard that these cars are more eco-friendly than ‘normal’ vehicles and recently it has became trendy to own a hybrid. But how many of us know just what is under the bonnet of a hybrid car? Let’s take a look at exactly how a hybrid works and why it’s a greener option than a regular car.
Put simply, a hybrid car is one that combines an internal-combustion engine with an electric motor, powered by sizeable batteries, to propel the vehicle. There are two types of hybrid car: parallel and series (also known as serial). In the first case, both the combustion engine and electric motor are connected to the mechanical transmission, which means that both engines are capable of powering the car, at the same time or separately. In series hybrids, only the electric motor is linked to the transmission, and it alone propels the car. The combustion engine is connected to a generator and is used purely to recharge the electric motor’s batteries.

The popular Prius hybrid car from Toyota Motor Corp. will be equipped with solar panels when the vehicle goes through a complete makeover as early as next spring.
The solar panels will be located on the roof and supply power to the five kilowatts needed to power the air-conditioning unit in the car. Toyota also intends to reduce the weight and thus improve the fuel efficiency even more.
This move will make Toyota the first major automaker to install solar panels in one of its car models. And the western automakers hopelessly try to catch up by offering everything besides green innovation.
