In the exhaust

DPF and SCR

The first greenhouse gas phase targets the whole vehicle rather than the engine, so this era is as much about aerodynamics, tyres and axle ratios as combustion. Downspeeding becomes standard: tall gears, low cruise revs.

Known issues

Too recent for a settled long-term record, which is itself worth saying. Early aftertreatment sensor complaints, nothing structural reported at scale.

Verdict

A genuine recovery from what came before it. The used market still prices International below its peers, which is an opportunity if the A26 record holds.
