What is the average top speed of a car?

Micro cars, that is, 2 seat cars with sub 1.3 litre engines, about 140 kph (85 mph) Small cars, 4 seats such as Toyota Corolla, 170 kph (106 mph) Medium cars, 5 seats such as BMW 318i, 230 kph (142 mph) Large cars, for example, Lexus IS 500, 250 kph (155 mph) Sports cars, such as Aston Martin DB8, 280 kph (174 mph), BMW M3 285 kph (178 mph) Chrysler Viper 273 kph (170 mph) Supercars like the Porsche GT3, 305 kph (190 mph) Hypercars such as Pagani Zonda, 370 kph (235 mph) Bugatti Veyron 407kph (253 mph) Ultima Aero 412 kph (257 mph) 99% of every day cars fit somewhere between 170 kph and 230 kph so the average top speed of most cars would be 200 kph (124 mph). Suvs, popular in the USA would average around 190 kph (118 mph) as they have large frontal areas and high drag. This is despite large power outputs. The true top speed of any particular car would occur on a smooth, flat, straight road with no wind and cool conditions. The engine needs to be freshly serviced and be able to produce maximum power. The tyre pressures need to be the maximum for that vehicle. All windows need to be wound up and the air conditioning off. Drive safely and within the law at all times!
