TheSuzuki R engine is aninline-three engine that has been produced bySuzuki since 2011. Initially introduced in thethird-generation MR Wagon, and intended as a replacement for theK6A engine, the R engine has since been used in various Suzuki's, such as theAlto, theWagon R, and theCarry.
For the release of thethird-generation MR Wagon in 2011,[1]Suzuki introduced a brand-new 658.2 cc (40.2 cu in)inline-threepetrol engine.[2] The new engine, known as the R06A,[3] was available innaturally-aspirated andturbocharged forms, which produced 54 and 64 PS (40 and 47 kW) respectively.[2] Introduced as a replacement to the K6A that had been in production since 1994, the R06A features four valves per cylinder (for a total of 12),dual overhead camshafts, with a bore and stroke of 64.0 and 68.2 mm (2.52 and 2.69 in) respectively.[4] In addition, the size and weight of the engine were reduced by adopting a cylinder head integrated into the exhaust manifold and a simpler catalyst case structure. 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 featurevariable 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 theAlto's range, with R06A-equipped Altos being called the Alto Eco.[5] TheWagon R also received both forms of the R06A engine in 2012, to coincide with the release of thefifth-generation model. In 2013, the R06A was used for the newSuzuki Spacia and the updatedSuzuki Carry, and in 2014, it was used for the newSuzuki Hustler.[3] The Carry was the first vehicle to use the R06A engine in arear-wheel-drive configuration, and had a slightly detuned 50 PS (37 kW) version of the engine.[3]
In December 2019,[6] Suzuki introduced a new version of the R engine for the 2020 modelSuzuki Wagon R and second-generationSuzuki Hustler. It's a naturally aspirated 657.7 cc (40.1 cu in) inline-three petrol engine, known as theR06D - the engine dimensions are different but the overall displacement is only 0.5 cc less than that of the R06A. Only available innaturally-aspirated form, it produces 49 PS (36 kW).
The R06A is a 658 ccinline threeDOHC 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 49 and 54 PS (36 and 40 kW) at 5700-6500 rpm with 58–63 N⋅m (43–46 lb⋅ft) of torque at 3500-4000 rpm for the naturally aspirated variants and 64 PS (47 kW) at 6000 rpm with 95–100 N⋅m (70–74 lb⋅ft) 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.
Naturally-aspirated
Turbocharged
The R06D is a naturally aspirated 658 ccinline threeDOHC 12 valve engine with VVT. Bore x stroke is 61.5mm x 73.8mm. Compression ratio is 12.0:1. Output is 49 PS (36 kW) at 6500 rpm with 58 N⋅m (43 lb⋅ft) of torque at 5000 rpm. This engine can also come in a mild hybrid configuration, but with the slightly less powerful W04C electric motor (2.6 PS and 40 N.m) and a lower capacity 3Ah battery.
