Fuel weight will affect the performance of the car, so fuel economy (thus efficiency) is a competitive advantage. Ways to increase power include: Increasing the engine displacement by one or both of two methods: "boring" - increasing the diameter of the cylinders and pistons, or by "stroking" - using a crankshaft with a greater throw.
Underdrive pulleys increase engine output by reducing the draw of the engine's accessories by slowing them down and reducing the horsepower (HP) they use. Horsepower gains from underdrive pulleys can vary by vehicle, engine, number of accessories and the amount of underdrive (improvements of up to 5–15 HP at the wheels have been seen).
Push-to-pass is a mechanism on a race car which provides the driver with the ability to increase the car's power for short periods, usually via a button on the steering wheel. The system is designed to make overtaking easier, and hence make the sport more exciting to watch.
For instance, a small car might need only 10–15 horsepower (7.5–11.2 kW) to cruise at 60 mph (97 km/h). It is likely to be geared for 2500 rpm or so at that speed, yet for maximum efficiency the engine should be running at about 1500 rpm (gasoline) or 1200 rpm (diesel) to generate that power as efficiently as possible for that engine ...
Purchasing a new car is exciting, but if you want to get your motor running and keep it going well over 100,000 miles, there are a few things you need to pay attention to. Check Out: The 20 Cars...
The advent of concern about fuel economy and emissions had major impacts on engine design. Some of the trade-offs reduced throttle response. Most new cars employ a drive-by-wire system, which includes electronic throttle control and can itself either reduce or increase throttle response (Depending on whether or not it's being employed on a performance car).
Designed for long-distance journeys, the Model 3 can go up to 363 miles on a single charge, and up to 195 miles after just 15 minutes of charging. 2025 Kia Soul MSRP: $20,290
The purpose of a nitrous purge is to ensure that the correct amount of nitrous oxide is delivered the moment the system is activated as nitrous and fuel jets are sized to produce correct air / fuel ratios, and as liquid nitrous is denser than gaseous nitrous, any nitrous vapor in the lines will cause the car to "bog" for an instant (as the ...
