In a series hybrid, the gasoline engine acts as a generator to charge the battery that powers the motor. This system is efficient for city riding where stop-and-go traffic is common. On the other hand, a parallel hybrid has both the engine and electric mo...
Tip: you can find the average efficiency of different electric cars in ourvehicle guides. Less noise pollution Air pollution is a big concern, especially in major urban centres, as many harmful gases contribute to climate change and the negative effects it brings. But noise pollution is also a...
Meanwhile, policymakers may consider enforcing stricter regulations on driving above set legal speed limits at 20 and 30 mph, given that this behavior has a much stronger influence on fuel consumption at lower speed levels. At the same time, this research has some limitations. First, compared to...
The engine in an electric vehicle has been replaced by an electric motor, and a battery pack has replaced the gas tank. The transmission stays the same, however, all-electric cars have a simplified gear system. To understand how an electric car works, consider the following points: When you...

policies solely focusing on reducing the carbon footprint of new cars cannot be sufficient in achieving climate targets without introducing regulations that target the existing fleet. This can be done through measures that encourage less driving (e.g., modal shift), retrofits of the existing fleet...
Ah, well that’s just the beauty of it. Because, you see, not only is the LS400 a cracking car in its own right, but given a decent set of pipes to breathe through it makes a noise likethe fabric of space and time being torn apart. ...
Alternative gearboxes, chain drives and some electric control apparatus may increase noise levels and attention must be given to ensuring that this does not result in excessive external noise; • Emissions (ADRs 26, 27, 30/..., 37/... & 79/...) – the emissions requirements do not ...
