Cummins B6.7 — the 6.7-Litre Inline-Six for Medium-Duty Trucks and Buses
The Cummins B6.7 is an inline six-cylinder diesel of 6.7 litres (6,690 cc) that replaced the earlier ISB6.7 designation; the 2021 update brought extended service intervals and a maintenance-free crankcase ventilation filter. A variable-geometry turbocharger (VGT) and high-pressure common-rail injection are core features, with output ranging roughly from 136 to 268 kW (183–360 hp) and torque up to about 1,100 N·m depending on the rating.

The B6.7 continues Cummins' long-running B-series lineage and superseded the smaller 5.9-litre ISB; the sources reviewed give no verifiable production dates beyond the 2021 revision. As with most current heavy-duty diesel engines in this class, it meets current emission standards through a combination of exhaust gas recirculation (EGR), a diesel particulate filter (DPF) and selective catalytic reduction (SCR) using AdBlue.
Typical duty includes medium-duty truck and bus chassis, school buses (long the default option across North America), transit buses, and light-to-medium commercial vehicles; variants on record include B6.7O 300, 260, 220 and 200, plus the "EV" ratings 300 EV, 220 EV and 200 EV.
Trade sources point to the VGT actuator mechanism as a known wear point — its degradation can disable the exhaust-brake function — so a functional check of the exhaust brake is worthwhile on used units, in addition to the usual review of oil and filter service intervals.
