Lightweighting is a concept in the auto industry about building cars and trucks that are less heavy as a way to achieve better fuel efficiency, battery range, acceleration, braking and handling. [1] [2] In addition, lighter vehicles can tow and haul larger loads because the engine is not carrying unnecessary weight. [3]
Federal regulations define a light-duty truck to be any motor vehicle having a gross vehicle weight rating (curb weight plus payload) of no more than 8,500 pounds (3,860 kg) which is “(1) Designed primarily for purposes of transportation of property or is a derivation of such a vehicle, or (2) Designed primarily for transportation of persons and has a capacity of more than 12 persons, or (3 ...
The power-to-weight ratio (specific power) is defined as the power generated by the engine(s) divided by the mass. In this context, the term "weight" can be considered a misnomer, as it colloquially refers to mass. In a zero-gravity (weightless) environment, the power-to-weight ratio would not be considered infinite.
Dry weight is the weight of a vehicle without any consumables, passengers, or cargo. It is significantly less than the weight of a vehicle in a drivable condition and therefore rarely used. Quoting a dry weight can make a car's weight and power-to-weight figures appear far more favorable than those of rival cars using curb weight. [4] [5]
A light commercial vehicle (LCV) in the European Union, Australia and New Zealand is a commercial carrier vehicle with a gross vehicle weight of no more than 3.5 metric tons (tonnes). [1] The LCV designation is also occasionally used in both Canada and Ireland (where the term commercial van is more commonly used).
A conventional ladder frame has a front steering axle with a 12,000 lb (5,400 kg) weight rating and tandem rear axles with a 40,000 lb (18,000 kg) weight rating. The truck can have a maximum weight of 52,000 lb (24,000 kg), including a 30,000 lb (14,000 kg) load. The total weight rating of the truck and trailer is 105,000 lb (48,000 kg).
Vehicle size classes are series of ratings assigned to different segments of automotive vehicles for the purposes of vehicle emissions control and fuel economy calculation. . Various methods are used to classify vehicles; in North America, passenger vehicles are classified by total interior capacity while trucks are classified by gross vehicle weight rating (GV
The HMEE is an armoured backhoe loader designed for high speeds in order to self-deploy with military convoys. Most backhoes are limited to much lower speeds. [2] It is also capable of towing heavy loads and has good off-road mobility.
