Initially introduced in the third-generation MR Wagon, and intended as a replacement for the K6A engine, the R engine has since been used in various Suzuki's, such as the Alto, the Wagon R, and the Carry.

==Overview== For the release of the third-generation MR Wagon in 2011,<ref>{{cite web |archiveurl=https://web.archive.org/web/20140624084233/http://www.suzuki.co.jp/mrwagon/ |url=http://www.suzuki.co.jp/mrwagon/ |title=Suzuki MR Wagon / MR Wagon Wit Special Site |language=Japanese |publisher=Suzuki |accessdate=23 December 2014 |archivedate=24 June 2014}}</ref> Suzuki introduced a brand-new {{cvt|658.2|cc|cuin|1}} inline-three petrol engine.<ref name="2011mrwagonlaunch">{{cite web |url=http://www.autoevolution.com/news/2011-suzuki-mr-wagon-launched-in-japan-30037.html |title=2011 Suzuki MR Wagon Launched in Japan |publisher=autoevolution |date=21 January 2011 |accessdate=23 December 2014 |first=Mihnea |last=Radu}}</ref> The new engine, known as the R06A,<ref name="suzukicarry2013launch">{{cite web |url=http://jp.autoblog.com/2013/08/29/suzuki-new-carry-kei-truck-to-launch-in-japan/ |title=R06A型エンジンと5速MTを縦置き! スズキ、軽トラック「キャリイ」をフルモデルチェンジ! |language=Japanese |trans-title=Place vertically R06A engine and 5-speed MT!

While this is good for fuel economy and emissions, the exhaust is more restricted which lowers horsepower and power potential. The naturally-aspirated versions of the R06A feature variable valve timing (VVT) on both the intake and exhaust valves (the first Suzuki engine to do so), and VVT on the intake valves of the turbocharged models.

For 2012, Suzuki added the naturally-aspirated version of the engine to the Alto's range, with R06A-equipped Altos being called the Alto Eco.<ref>{{cite web |url=http://www.carscoops.com/2011/11/new-jdm-suzuki-alto-eco-returns-up-to.html |title=New JDM Suzuki Alto Eco Returns up to 32km/L – 75MPG |publisher=Carscoops |date=25 November 2011 |accessdate=23 December 2014}}</ref> The Wagon R also received both forms of the R06A engine in 2012, to coincide with the release of the fifth-generation model. In 2013, the R06A was used for the new Suzuki Spacia and the updated Suzuki Carry, and in 2014, it was used for the new Suzuki Hustler.<ref name="suzukicarry2013launch"/> The Carry was the first vehicle to use the R06A engine in a rear-wheel-drive configuration, and had a slightly detuned {{cvt|50|PS|kW|0}} version of the engine.<ref name="suzukicarry2013launch"/>

In December 2019,<ref>{{cite web |url=https://m.indianautosblog.com/suzuki-wagonr-new-engine-japan-p319293 |title=Suzuki WagonR range gets a new engine in Japan |publisher=indianautosblog |date=31 December 2019 |accessdate=30 March 2020 |first=Singh |last=Prashant}}</ref> Suzuki introduced a new version of the R engine for the 2020 model Suzuki Wagon R and second-generation Suzuki Hustler. It's a naturally aspirated {{cvt|657.7|cc|cuin|1}} inline-three petrol engine, known as the '''R06D''' - the engine dimensions are different but the overall displacement is only 0.5&nbsp;cc less than that of the R06A. Only available in naturally-aspirated form, it produces {{cvt|49|PS|kW|0}}.

==R06A== The R06A is a 658 cc inline three DOHC 12 valve engine with VVT. Available in naturally aspirated or turbocharged. Bore x stroke is 64.0mm x 68.2mm. Compression ratios are 9.1:1 (turbo) and 11.0-11.5:1 (NA). Output is between {{cvt|49|and|54|PS|kW|0}} at 5700-6500 rpm with {{cvt|58-63|Nm|lbft|0}} of torque at 3500-4000 rpm for the naturally aspirated variants and {{cvt|64|PS|kW|0}} at 6000 rpm with {{cvt|95-100|Nm|lbft|0}} at 3000 rpm of torque for the turbocharged variants. The R06A can come paired with Suzuki's mild hybrid system, with the W05A electric motor (3.1 PS and 50 Nm) and a 10Ah battery.
