A car has to be fuel efficient. It means it has to completely burn the fuel.
Lighter weight, more aerodynamic, and more fuel efficient engines, transmissions, and tires.
Yes, the indirect injection is more fuel efficient because it provides stability to the engine.
There hasn't really been a brand of semi trucks recognized as the most fuel efficient. Since they run on diesel a more efficient fuel, semi trucks already are more fuel efficient than cars in terms of size and power.
No, it is less fuel efficient.
Electric pumps are more efficient pushing versus pulling and the fuel cools the pump.Electric pumps are more efficient pushing versus pulling and the fuel cools the pump.
They don't necessarily use more fuel. Such cars are more streamlined, and actually tend to be more fuel efficient. The real determining factor is in how you drive. The faster you drive, the more fuel you use to overcome wind resistance. If you buy a fast car but drive it as reasonable speeds, you'll be doing better than a person who drives a typically slower, bulkier vehicle, and keep the pedal mashed to the floor.
When it comes to fuel efficient and luxury cars the best bet is to compare hybrid-engine designs. More and more luxury car companies are now coming out with fuel efficient hybrid-engine designs.
A manual transmission civic is more fuel efficient than an automatic transmission. That goes for just about any car.
Our school is in need of a heating system that is more fuel-efficient than the current system. or Our school needs a heating system more fuel-efficient than the current one.

It depends on the fuel efficiency of your mode of transport. Bikes, for example, are far more efficient that a huge car. Second, it depends on the type of fuel used and its cost.
