Hybrid cars in Hong Kong first came onto the scene in the late 1990s, and the world hailed them as one of the main solutions to the problem of climate change and spiralling fuel costs. However, they have also come a long way since their inception more than ten years ago - here we look at developments in electric cars in Hong Kong and electric sports cars in Hong Kong.

The world is slowly but surely falling in love with hybrid vehicles. They were rare and untrusted when they first came onto the scene in the late 1990s, but the technology has now been proven, and manufacturers like Mercedes in Hong Kong are now making even bigger steps towards popularizing and advancing electric cars in Hong Kong.

Lithium ion batteries have recently been made by the luxury car manufacturers, the first in the world. Since Karl Benz first patented the two-stroke internal combustion engine in 1879, Mercedes have been known for innovation - here we look at the new electric engine made by the company and other ways that engineers are working to clean and improve engine performance.

While lithium ion batteries are commonplace in many household appliances and electrical items, they have been quite a challenge for engineers to incorporate into normal luxury automobiles in Hong Kong. However, at the Paris Motor Show, Mercedes recently unveiled its first hybrid car to be sold in Hong Kong, the S400 BlueHybrid.

It is a modified S-Class sedan, one of Hong Kong's most popular luxury autos, and is the world's first implementation of a lithium ion battery. The S400 hybrid vehicles in Hong Kong not only have the new battery, but run on diesel, a more efficient and cheaper fuel than traditional petrol.

There have also been many standard fuel-saving techniques implemented on luxury cars in Hong Kong, like fuel injection, turbocharging and electrical controls. However, most of these are used as power aids, while the vehicle uses the same amount of fuel, not as efficiency measures. Yet an Iowa state University assistant professor, along with 15 graduate students, is studying engines to help improve their efficiency and reduce their emissions.

He even keeps a piston by his desk, to keep his mind on the job. Cobustion projects are the main focus of this group of scientists' lab work. Diesel engines are being studied with the goal of implementing them in hybrid cars in Hong Kong, like Mercedes have done.

They are also developing a computer model of an engine that runs on gasoline, which will enable researchers to much more quickly and easily test new technologies. The computer model will be crucial in deciding which technologies will work in electric cars in Hong Kong, without the massive amounts of time that such work usually takes.

An assistant professor of mechanical engineering is working with the group also, using laser-based, high speed sensors that record images of sprays of injection and combustion inside a cylinder. The group is also studying how plastics dissolved in biodiesel affect the performance of engines, trying to find a technology that may be implemented on cars it proactively help the environment, rather than simply reducing the vehicle's impacts.

The technology for diesel and hybrid cars in Hong Kong could see waste plastic recycled by mixing it into fuel for vehicles.
