Reintjes, Daimler Trucks’ global head of powertrain and manufacturing, has said
that for proprietary, that is independent, suppliers of engines, transmissions
and drive axles in North America, the complexity of meeting the operating
requirements ‘of all customers and all their different applications, is killing
them’.
In an interview with the US weekly publication Transport Topics, Reintjes said that,
although he ‘very much respected’ Cummins, Eaton, Meritor and Dana as
competitors, he maintained they were unable to match the mission-tailored
powertrain capability of vertically-integrated truck and bus makers such as
Daimler.
He cited the trend towards
despeeding of engines in combination with ‘taller’ axle ratios and automated
mechanical transmisions with strategic electonically-managed gearshift timings
in order to enhance fuel economy while meeting tough pollutant emission limits.
For such efficiency programmes
to be optimised, Reintjes said: ‘very sophisticated management’ of software was
needed, requiring, on the hardware side, ‘very intelligent controllers’ able to
communicate with each other.
That, he declared, was the ‘big
advantage’ of Daimler’s integrated powertrain approach.
