Nissan LEAF new car Technology.New generation electric cars aren't just 'normal' cars fitted with a battery instead of an internal combustion engine. They are a whole new type of car.
Nissan LEAF, the world's first electric vehicle that has similar affordability, performance and practicality of a 'normal' five-seat hatchback, is anything other than a typical hatchback. It's a revolution in zero emissions mobility.
If we start with the engine: There is no engine oil, camshafts, valves, inlet manifolds, exhaust or pistons. And because an electric car produces no tailpipe emissions, there is no need for a catalytic converter, anti-pollution plumbing, expensive electronic NOx or carbon monoxide controls, or pricey injection systems.
Rather, electric engines are incredibly simple. This cuts maintenance costs and boosts reliability. Their cleanliness includes noise: because there is no combustion, there is virtually no noise. There is also no exhaust.
Electric engines are small. So that's less space for the motor and more space for people and their belongings. And they have no conventional transmission, further reducing space devoted to the mechanicals.
Nissan LEAF, like all electric cars, can develop its maximum torque instantly. And it can maintain that big delivery of torque over a very wide rev band. In some circumstances, Nissan LEAF is faster than a car with an internal combustion engine. That 'instant' torque means Nissan LEAF has excellent initial acceleration. This is particularly useful in urban or suburban driving, the natural habitat of the electric car (and it's also where an EV can do most good - in polluted cities where loads of people live.) The electric car's much wider torque and rev bands also enables Nissan LEAF to offer more linear acceleration than the typical gas.
