Vehicle with caterpillar treads over the rear wheels, to provide motive power, but steered by normal front wheels. This is used, especially, on military tasks, as armored car. In the photo is presented an early armored halftrack used on police.

Known Japanese automobile maker and innovator, founder of actual Honda Motor Company. Born in Komyo, central Japan, on 17th November 1906, Soichiro Honda was apprenticed at a Tokyo garage in the boom time between the end of the First World War and the Great Kanto earthquake of 1923. The garage was ruined in the earthquake and only Soichiro and a senior apprentice remained. In 1925 the owner Yuzo Sakakibara inspired Soichiro to build a racing car on a 1916 Mitchell chassis, with a Curtis-Wright 8-litre V-8 aircraft engine.

In the 1930s Soichiro set up an engineering business making piston rings, finding a ready market in Japan's flourishing aircraft industry. In 1942 Toyota acquired 40 per cent of the shares, and following the war Honda sold the remainder, half expecting the firm to be liquidated. He then took a year off, reputedly spending the time making sake and partying, then in October 1946 set up the Honda Technical Research Institute later the Honda Motor Company. Unlike many contemporaries, Soichiro Honda was an extrovert, wore colourful clothes, and claimed that nonconformity was essential to an artist or innovator.

Today, Honda Corporation employs over 100,000 people in the USA and Japan, and is one of the world's largest automobile companies.

Unit of power in the English system for measuring the rate at which an engine or other prime mover can perform mechanical work. It is usually abbreviated hp. Its electrical equivalent is 746 W, and the heat equivalent is 2545 Btu. One horsepower was originally defined as the amount of power required to lift 33,000 lb 1 ft in 1 min, or 550 ft-lb per sec.

Net horsepower or bhp (brake horsepower) and KW (kilowatts) are the standard units. Higher horsepower increases vehicle top speed. Equal displacement (size) engines that rev higher often produce more power than lower revving engines, because more air and fuel is burned in a given time. A typical 3.0L 24V V-6 produces 190 bhp @ 6400 rpm. A lower revving 3.0L 12V V-6 produces 160 bhp @ 5000 rpm. The 24-valve V-6 makes 190 BHP because it can rev higher (and breathe better) than the similar 12-valve V-6.

Brake or Shaft Horsepower is more commonly used to indicate the practical ability of the engine, or the maximum performance, which is the indicated horsepower minus the power lost through heat, friction, and compression.

First South Korean cars maker. In Korean language, the word "Hyundai" means "modern". In 1967, Hyundai built its first car in a brand new plant at Ulsan Englishman George Turnbull was managing director and the car was a Ford Cortina. For the next seven years, the factory churned out Cortinas and Granadas, but only for the South Korean market.

In 1974, was produced the first car using the Hyundai emblem: Hyundai Pony. The engine, transmission and suspension were all from a previous model Mitsubishi Lancer, but the Pony's bodywork and trims were new, designed by Giugiaro's Ital Design studios.

The new Elantra, which debuted in early 1996, is a vehicle line developed exclusively by Hyundai with no reliance on licensed technologies from other manufacturers. Elantra was the first vehicle endowed with the Hyundai logo, a stylized "H" in an oval perimeter, signifying two people linking their arms together. The new Elantra also features the second Hyundai developed engine, the Beta. The first exclusively Hyundai designed engine, the Alpha, is currently featured in the Accent subcompact which debuted in February 1995.
