Automotive makes are continuing to evolve in all respects. One of the areas most resources are devoted to researching and developing involves new systems for improving vehicle efficiency. Vehicles intended for freight transport are no exception, and practically all manufacturers are committed to lower-consumption engines, more highly developed gearboxes and a whole series of measures aimed at reducing fuel use.
There are plenty of examples, almost as many as there are models currently on the market aimed at transporting freight. Some makes offer different packages of savings measures, such as MAN’s ‘Efficiency Program’ or Renault Trucks’ ‘Optifuel’ solutions, including everything from low-consumption engines with an automatic system to turn them on and off when the vehicle halts, robotised gearbox, specific lubricant and low rolling resistance tyres.
Gearboxes are also a field where the response-consumption ratio can be improved, as shown by makes like MAN and its ‘TipMatic’ transmission with ‘EasyStart’ (help with hill starts), Scania and its ‘Opticruise’ and Volvo Trucks and its ‘I-See’ gearbox, which will arrive in 2013 and works as an automatic pilot, changing gear and using gradients for saving fuel. Active speed programmers, such as ‘Active Prediction’, used by Scania on some of its models, also contribute to reducing consumption as they know the route of the road in advance via GPS and use inertia as much as possible.
