About the Volvo D11 (Mack MP7)
The Volvo D11 (Mack MP7) is the smaller variant in the Volvo Group commercial engine family — 10.8 liters vs the D13's 12.8L. Used in regional haul, vocational, and refuse applications where the D13's full power isn't needed. The D11 is particularly popular in refuse trucks (Mack LR, TerraPro) and dump applications where lighter weight provides payload advantages.

Common problems
Same family as D13 but lower frequency. EGR cooler, DEF system, NOx sensors at high mileage.
Maintenance schedule
Same as D13.
Pros and cons
✓ Pros
- • Lighter than D13 for payload-sensitive operations
- • Same family DNA — proven
- • Adequate power for regional/vocational
- • Lower cost than D13
⚠ Cons
- • Smaller power output limits applications
- • Same parent-bore issues as D13
- • Lower resale than Cummins L9 in vocational markets
Resale value impact
Modest impact — D11/MP7 trucks somewhat lower resale than Cummins L9 equivalents in vocational markets.
