The H family is a line of automobile 60° V6 engines from Suzuki. Ranging in displacement from {{convert|1998|to|2736|cc|L|1|abbr=on|disp=flip}}, the H family was a modern all-aluminum engine with dual overhead cams, 24 valves, and multi-port fuel injection. It was co-developed with Mazda and Toyota, which used a similar design in their 2.0 L KF V6 and the Toyota VZ engine. The H family was introduced in 1994 with the H20, but Suzuki, Toyota and Mazda's designs diverged greatly with the former increasing displacement and the latter experimenting with alternative induction technologies and smaller engine sizes. The four-cylinder J engine, which appeared in 1996, shared parts and design with the H family.{{cite web | url = https://www.suzuki.co.jp/suzuki_digital_library/7_engine/4-j.html | archive-url = | archive-date = | title = ンエンジン紹介: J系 | trans-title = Engine Introduction: J series | language = ja | work = Suzuki Digital Library | publisher = Suzuki Motor Corporation | date = 2021 }}
H20A
The H20A displaces {{convert|1998|cc|L|1|abbr=on|disp=flip}}; bore and stroke is {{convert|78x69.7|mm|in|2|abbr=on}}. With a 9.5:1 compression ratio, it produces {{convert|107|kW|PS hp|0|abbr=on}} at 6,500 rpm and {{convert|172|Nm|lbft|0|abbr=on}} at 4,000 rpm.{{cite book | title = Katalog der Automobil Revue 1997 | editor-last = Büschi | editor-first = Hans-Ulrich | publisher = Hallwag AG | location = Berne, Switzerland | language = German, French | page = 516 | volume = 92 | date = March 6, 1997 | isbn = 3-444-10479-0 }}
Applications:
- 1994–1999 Suzuki Escudo/Vitara
H25A
The H25A displaces {{convert|2495|cc|L|1|abbr=on|disp=flip}}; bore and stroke is {{convert|84x75|mm|in|2|abbr=on}} and produced {{convert|106|kW|PS hp|0|abbr=on}} when first introduced.Automobil Revue 1997, p. 518 With a 9.5:1 compression ratio, it produced {{convert|106|kW|PS hp|0|abbr=on}} at 6,500 rpm and {{convert|203|Nm|lbft|0|abbr=on}} at 3,500 rpm on its introduction, with a 2001 update increasing this to {{convert|116|kW|PS hp|0|abbr=on}} and {{convert|213|Nm|lbft|0|abbr=on}}. It is also being considered and used for various ultra-light aircraft propulsion systems, like the Titan T-51 Mustang.
Applications:
- 1996–2005 Suzuki Escudo/Vitara Wagon/Estate (LWB) **not in Australia
- 1998–2005 Suzuki Grand Vitara (Only US and Canada)
- 2001–2004 Chevrolet Tracker
- 2003–2006 Suzuki Grand Escudo XL-7 (Indonesia Only)
H27A
The H27A is a modern version of the H25A, a reliable motor displacing {{convert|2736|cc|L|1|abbr=on|disp=flip}}, coming from an {{convert|88x75|mm|in|2|abbr=on}} bore and stroke (VVT added in 2006). The engine is tuned to achieve most of its torque at low revs at the expense of raw power at high revs, making the engine very responsive in day-to-day driving. It produces {{convert|138|kW|PS hp|0|abbr=on}} at 6,000 rpm and {{convert|250|Nm|lbft|0|abbr=on}} at 3,300 rpm.
Applications:
- 2000 - 2009 XL-7
- 2006 - 2008 Grand Vitara (North American and Taiwan markets){{Cite web |last=張之杰 |date=2006-03-17 |title=精緻時尚化的荒野大驃客– Suzuki Grand Vitara JP 2.7試駕 |url=https://roadtest.u-car.com.tw/roadtest/article/4663 |archive-url=https://web.archive.org/web/20250427083041/https://roadtest.u-car.com.tw/roadtest/article/4663 |archive-date=2025-04-27 |access-date=2025-04-27 |website=roadtest.u-car.com.tw}}
