Since 2011, a factory in Japan has been assembling the 0.6-liter 12-valve Suzuki R06A engine, which powers the company’s well-known kei vehicles, including the Alto, Hustler, and different Wagon R models. The unit is available in two versions: atmospheric for 50–55 horsepower and turbocharged for 65 horsepower.

Disadvantages of the Suzuki R06A engine
Owners complain about the unit’s lengthy winter warm-up on specialized forums;
On runs of 150–200 thousand kilometers, the turbine in supercharged versions frequently fails;
When a thin timing chain is stretched, the valves bend because it has roughly the same resource. On trifles, sensors and unreliable ignition coils can cause this.
