PACCAR MX-13 Euro 6
New Generation Coach & Bus engine

The New Generation 12.9 Litre PACCAR MX-13 engine further lowers its CO2 footprint. Excellent and increased torque at low engine speeds and a high performance is available over a wide engine speed range. The MX-13 is the best solution for luxury Coaches demanding top performance.

An optimized combustion process in combination with a reduction of parasetic losses and an improved air management system results in the lowest fuel consumption. In combination with the use of sustainable (BIO) fuels it can reduce CO2 contribution by 90% compaired to regular diesel.
Using state of the art technologies we achieve highest reliability and durability. R&M costs are further decreased including a maintenance interval up to 200.000km. The best engine has become even better and is ready for the future .
