Cummins ISX12 SmartAdvantage™ Powertrain.
The ISX12 SmartAdvantage Powertrain is an excellent choice for regional-haul applications and day-cab operators who want smooth performance, proven reliability and reduced operating costs. This fully integrated package delivers 2-4% better fuel economy while achieving near-zero emissions with the Cummins Aftertreatment System.
SmartTorque2 (ST2) technology delivers higher torque earlier in the rpm range, so you can cruise at 1200-1320 rpm and still get the pulling power needed to match real-time load demand. The ISX12 SmartAdvantage Powertrain also includes Vehicle Acceleration Management (VAM).
- ST2 automatically senses vehicle weight, grade and operating gear, then selects the optimum torque for the best fuel economy and performance in every gear. Higher torque is delivered earlier in the rpm range, so you can cruise at 1200-1320 rpm and still get the torque and power needed to match real-time load demand.
- SmartCoast™ is an optional feature within the ADEPT™ suite of Cummins electronic engine features that senses when a vehicle is descending downhill (up to a 4% grade), then disengages the driveline to take full advantage of gravity and momentum. When SmartCoast is active, the ISX12 returns to idle. On routes across hilly terrain, this feature, together with ST2, can increase fuel economy by up to 3%.
- VAM maintains a smoother acceleration rate from the launch of the vehicle, maintaining more consistent acceleration due to a more efficient transition through the gears. This enhances the driving experience and reduces driveline wear while increasing fuel economy.
