Well, for starters the Number of cylinders and designs have helped the more cylinders the more efficient a motor runs, The number of valves the more that comes in the more the air has to go out and the faster it is pulled in the faster it has to go out, The fuels well the higher the octane of the fuel it burns higher with additives like nitrogen the less carbonization is left and the motor runs longer it causes less stress from carbon build up that is gas motors. The Diesel motors are already quite efficient because of the high pressures and high burning. Then Hybrids and FEV's and and technology like VVTI and cylinder deactivation. Hybrids run electric motors and gas motors, (FEV) Full Electric Vehicles run only on electric motors less moving parts last longer very little engine ware, Now VVTI and Vtec along with Cylinder deactivation - (VVTI) is Variable Valve Timing Intelligence and the same as VTec it will take to long for me to explain so you can look that information up. Several other technologies are Power adders i.e. - Super Chargers and Turbo Chargers those are forced induction systems all they do is add more air at a higher rate than the standard o.e.m. but all of this I have said a lot of this technology still holds true to taday's standards but a lot of it is going away because technology that has already been used in high end sports cars are now being used more in the average car like for instance a 6 cylinder motor that pushes over 500HP do some research a good start will be fuel systems Carbeurator vs Fuel injectors, then go to ignition - Spark Plugs vs Glow plugs and Distributors vs Coil packs and Coil on plugs. Then to Cold air intakes and Turbos and Superchargers, 45,6,8,10,12 cylinder motors OHC vs DOHC and Pushrod/In Block Cam, Cast Iron blocks vs Aluminum or Titanium or Carbon Fiber blocks and Technology such as Hemi there is so much out there that there is litterally to much for me to explain in detail.

How can the number of cars on the road be reduced?
engineers have improved the efficency of cars by designing better engines and tires . another way to save energy is to use public transit system and carpool . in the future ,cars that run on electricity may provide the most energy savings of all.
How have enginers improved the energy effinciency of cars?
bh
What is one way to get more energy out of fuels?
using energy efficiency stuff like cars
Which describes increasing the efficiency of an energy resource?
making cars that get better gas mileage
What describes increasing the efficiency of an energy resouce?
making cars that get better gas mileage
Do engineers study cars?
There are many types of engineers such as:aerospace engineers,canal engineers,chemical engineers,civil engineers,electrical engineers,environmental engineers,genetic engineers,industrial engineers,materials engineers,mechanical engineers,structural engineers,systems engineers,just to name a few.Some of which do study cars.
How are new Toyota cars different than older models?
"With all new cars there are upgrades and new features in comparison with their earlier models. New Toyota cars are more energy efficient, such as with the hyrbrid cars. Also the steering has improved, and the overall design has improved as well."
How can electric cars be improved?
Longer battery range, faster recharge time and batteries resistance to blunt deformation. "To achieve efficiency, we must achieve lightness" - so to reduce weight would also be applicable, though it is not specific to electric cars. There is also technology for reclaiming lost energy through breaking, yet it is also not specific to electric cars.
What type of engineers work with cars?
Car engineers, design engineers, tire safety engineers; anyone that would be involved in the design, assembly, safety, or testing of cars.
Why solar panels are not mounted on the cars roofs for fuel efficiency?
Expensive, and will save very little energy. Not practical.
Are hybrids better that gas cars?
While they are not necessarily better, they do have pros such as greatly improved gas mileage, and lower efficiency. I would contact a dealership for more information.
How have cars improved?
Cars have improved in many ways. The advent of seat belts, safety glass, anti-lock brakes, air bags, power steering and power brakes have all improved cars.
