European car makers come in a far distant second, and American automakers are last, although "Buick's entire lineup scored average or better." The top cars, according to multiple sources
The moment of inertia about a vertical axis of a vehicle Size: feet feet meters handling, safety lower is better for parking on narrow parking slots, higher is better for lateral Traffic collision: Shift time: mSec ms ms acceleration lower is better for vehicles equipped with automatic transmissions: Specific fuel consumption (thrust) lb/(lbf·h)
An automobile is a highly engineered collection of complex components, each of which has its own lifespan and longevity characteristics. The MTBF (mean time between failures) of some components is expected to be smaller than the life of the car, as the replacement of these is considered part of regular maintenance.
Electric vehicles and pickups are the least reliable vehicles sold in America, whereas hybrids and sedans are the most reliable, according to Consumer Reports 2022 Annual Auto Reliability survey.
This classification helps defining the safety requirements necessary to be in line with the ISO 26262 standard.

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 efficiency of internal combustion engines depends on several factors, the most important of which is the expansion ratio. For any heat engine the work which can be extracted from it is proportional to the difference between the starting pressure and the ending pressure during the expansion phase.
