VTEC was introduced as a [[Overhead camshaft#Double overhead camshaft|DOHC]] (dual overhead camshaft) system in Japan in the 1989 [[Honda Integra]] XSi,<ref name="1989vtecengine"/> which used the {{convert|160|bhp|kW|abbr=on}} [[Honda B engine#B16|B16A]] engine. The same year, Europe saw the arrival of VTEC in the Honda Civic and [[Honda CRX]] 1.6i-VT, using a {{convert|150|bhp|kW|abbr=on}} B16A1 variant. The [[United States]] market saw its first VTEC system with the introduction of the 1991 [[Acura NSX]],<ref>{{cite web|url=http://www.superstreetonline.com/features/htup-0905-vtec-history-and-technology/|title=VTEC - History & Technology - Honda Tuning Magazine|date=20 May 2009|website=superstreetonline.com|access-date=27 March 2018}}</ref> which used a 3-litre DOHC [[Honda C engine#C30A|C30A]] V6 with {{convert|270|bhp|kW|abbr=on}}. DOHC VTEC engines soon appeared in other vehicles, such as the 1992 [[Acura Integra GS-R]] ({{convert|160|bhp|kW|abbr=on}}[[Honda B engine#B17|B17A1]]), and later in the 1993 [[Honda Prelude]] VTEC ({{convert|195|bhp|kW|abbr=on}} [[Honda H Engine#H22A|H22A]]) and [[Honda Del Sol]] VTEC ({{convert|160|bhp|kW|abbr=on}} [[Honda B engine#B16A3|B16A3]]). The [[Integra Type-R|Integra Type R]] (1995–2000) available in the Japanese market produces {{Convert|197|bhp|kW PS|0|abbr=on}} using a [[Honda B engine#B18C5 (Type R)|B18C]] 1.8-litre engine, producing more horsepower per litre than most super-cars at the time. Honda has also continued to develop other varieties and today offers several varieties of VTEC, such as i-VTEC and i-VTEC Hybrid.
