Which is most fuel efficient car?
The most fuel effincient car is the Honda Hybrid.
Hydrogen-fueled cars such as the Honda Clarity FCX and new H2 Mazda RX-8 don't even use gasoline/diesel.
Volkswagen Lupo 3L uses 78 miles per US gallon or 94 miles per Imperial gallon.
Fuel efficiency is often confused with fuel economy. If you drive a Toyota Prius like an angry teenager, you probably get worse fuel economy than if you drove a BMW 325i like a 45 year old schoolteacher, even though the BMW has far worse "fuel efficiency".
The amount of fuel saved depends on how many miles are driven and what car they are compared to. Hybrid cars are roughly twice as fuel efficient as non-hybrid cars. If you are driving a less fuel efficient car they can be three times as efficient, but some comparable non-hybrid cars get as much as 75% the mileage of hybrids, so the range is considerable. For estimation purposes, take the miles driven, assume 25 miles…
Answer It depends on the type of driving undertaken. Petrol Hybrids work well in hilly country and around the city, but it has been proven in real-world tests in this country (Australia) that small(ish) efficient diesels will outdo petrol hybrids in open road conditions ( of which there are many thousands of kilometres in this country) as at speed on a highway hybrids are at their least efficient. Brake regeneration, engine stop-start and other fuel-saving…
