Question 1

How do hybrid cars work?

Hybrid cars run off a conventional petrol or diesel engine, as well as an electric motor and battery. The combination of these power sources achieves improved fuel efficiency, which in turn saves money and reduces pollution.

Question 2

How do electric cars work?

Electric cars are powered by electric motors, which use rechargable batteries. These batteries also power the ancillary systems on the cars, including the wipers and lights. An electric car can be charged with a charging cable or at a charging station. It takes any time between 30 minutes to 12 hours to charge an electric car.

Question 3

What is a hybrid car?

While traditional vehicles use petrol or diesel to power their internal combustion engine, a hybrid car incorporates an electric motor and battery alongside more conventional parts in its combustion engine. It can therefore power the car partially or wholely by electric energy.

Question 4

Pros & cons
of electric

Electric cars produce less CO2 than even some of the most efficient fossil-fueled cars, making them a more environmentally friendly option than their diesel or petrol powered counterparts. With electric cars, air pollution from tailpipe emissions is reduced, therefore air quality is improved. Electric cars get the green light.

Question 5

Do electric cars save money?

Yes. Fuel costs for electric cars are significantly smaller than for petrol and diesel engines. As electric cars produce low levels of CO2 emissions, they are road tax exempt . The cost of an annual service is also significantly lower than a petrol or diesel car.

Question 7

Electric supercars

Expensive electric car batteries are the primary reason why electric cars cost more to build than petrol or diesel cars. Economies of scale also play a part - limited amounts of electric cars being produced means that prices stay relatively high. However, the costs of running an electric car are much reduced compared to traditional models.

How to use less fuel

  • Alter your driving style - less speeding and accelerating.
  • Improve your mileage - drive with correctly inflated tyres.
  • Reduce fuel consumption - remove excess weight from your car.

  • Avoid unnecessary driving - combine trips or travel by foot or bike.
Question 11

How much is a hybrid car?

New hybrid cars can be as cheap as £15,000. However, they will typically cost around 20% more to buy than petrol and diesel powered cars due to the drivetrains, which transmit power to the driving wheels. Drivetrains require larger, more powerful batteries, which add to the cost of a hybrid car.
