Mack Trucks has shown off its new Super Econodyne low-rpm powertrain that promises significant fuel economy improvements over existing truck engines.
At a day-long event Wednesday at the Mack Customer Center in Allentown, Pa., yesterday, the company also announced further bundling of its ownership services to include financing plans.
By basically reducing engine cruise speed by 200 rpm, Super Econodyne improves fuel economy by 2% over current Mack offerings and 5% over pre-2007 engines that many customers are still using, said David McKenna, director of powertrain sales and marketing. Aerodynamic improvements to SE-equipped Pinnacle tractors can stretch fuel economy by up to 15%.
