Technical features and description

Power unit system

This model is equipped with a newly developed V6, 4-stroke engine that has 60° cylinder banks.
The cylinder heads feature plastic cylinder head covers, shimless valve lifters, and exhaust covers
that are integrated into the cylinder heads. The cylinder block features a crankcase equipped with
an oil cooler, a crankshaft with an integrated drive sprocket, and sleeveless cylinders. Other features
include compact VCT assemblies with a narrow timing belt, and a plastic bottom cowling.
These newly designed components have reduced the weight by 4% compared with previous V6
models.
