DETROIT – The common perception in the pickup truck market is that bigger is better. That’s why Ram unveiled the 2500 and 3500 Heavy Duty versions of its trucks Monday at the North American International Auto Show.

The company used the same auto show last year to bring out the smaller 1500 truck. While that truck is targeted at mainstream buyers, the larger models are built for people who need a little more power and capability out of their trucks.

To satisfy those buyers, the bigger trucks are offered with two engine choices. The standard engine is a potent 6.4-liter V8 that puts out 410 horsepower and 429 pound-feet of torque.

For even more power, there’s also an available Cummins 6.7-liter turbodiesel V8. That engine generates 400 horsepower and a class-leading 1,000 pound feet of torque. All that power gives the big truck the ability to tow up to 35,100 pounds or carry up to 7,680 pounds in the bed.

While the truck will be available in a more work-oriented trim level, Ram is giving extra attention to the top-of-the-line models that feature plenty of leather, real wood and the latest technology. Ram managers say this will also be the quietest Heavy Duty truck they’ve made, with active noise cancellation and acoustic glass.

Pricing has not yet been announced.
