However, it is the power a car can produce at the wheels (wheel horsepower or whp) that matters when it comes to acceleration performance. Wheel horsepower equals brake horsepower minus drivetrain losses, which can be anywhere from about 10% to 25%. [12] Power-to-weight ratio: hp/lb hp/lb
Measuring the 0 to 60 mph speed of vehicles is usually done in a closed setting such as a race car track or closed lot used for professional drivers. This is done to reduce risk to the drivers, their teams, and the public. The closed course is set up for test-drives in order to reduce any variables, such as wind, weather, and traction.
Drag is a force that acts parallel to and in the same direction as the airflow. The drag coefficient of an automobile measures the way the automobile passes through the surrounding air. When automobile companies design a new vehicle they take into consideration the automobile drag coefficient in addition to the other performance characteristics ...
Power-to-weight ratio is a measurement of actual performance of any engine or power source. It is also used as a measurement of performance of a vehicle as a whole, with the engine's power output being divided by the weight (or mass) of the vehicle, to give a metric that is independent of the vehicle's size. Power-to-weight is often quoted by ...
Vehicle dynamics is the study of vehicle motion, e.g., how a vehicle's forward movement changes in response to driver inputs, propulsion system outputs, ambient conditions, air/surface/water conditions, etc. Vehicle dynamics is a part of engineering primarily based on classical mechanics.
A performance car is a car that exhibits above-average capabilities in one or more of the following areas: acceleration (torque and throttle response), top speed , cornering and braking. [1] It is debated how much performance is required to move classification from standard to high performance.
Car and Driver Editor in Chief Tony Quiroga said part of what makes the Hyundai Ioniq 5 N so desirable is the driving experience it delivers, which is similar to that of a gas-powered vehicle.
Car and Driver (CD or C/D) is an American automotive enthusiast magazine first published in 1955. In 2006 its total circulation was 1.23 million. [ 2 ] It is owned by Hearst Magazines , who purchased it from its prior owner Hachette Filipacchi Media U.S. in 2011.
