Summary


• Electrification has entered the commercial vehicle arena

• It is not about substitution, it is about new opportunities

• System knowledge is key

• machine, attachment, application (duty cycles!)

• engine, transmission, electric drives & control

• Simulation & Diagnostics

• Collaboration opportunity

• Common components

• Energy storage adds future potential
