Increased Compression Ratio

The compression ratio has been increased from 9.7:1 to 10.6:1 to achieve greater top speed and acceleration produced by the 2.0-litre displacement inline four-cylinder engines. Lean Burn fuel efficiency has also been significantly improved compared to the outgoing “A” series models. Tests have demonstrated as much as 10% improvement across mid-range to high-end cruising speeds.

ADVANTAGE

■ Improved combustion results in greater fuel efficiency compared with "A" series models.
■ 10.6:1 Compression Ratio contributes to improved engine torque.

Suzuki Micro Plastic Collecting Device (MPC)

Suzuki’s Micro-Plastic Collecting Device (MPC) is part of Suzuki’s Clean Ocean Project initiative, which collects micro-plastic by filtering the returning ocean water after it has been used for cooling the outboard motor., without any effect on performance when boating.
