SPORTS TRUCK? With the Ram SRT-10, Dodge aims to build a Viper with a truck body.

Numbers play a big role in the new Dodge Ram SRT-10. We'll start with 500, which the truck's engineers reached or exceeded four times: in hp (500 at 5600 rpm), torque (525 lb-ft at 4200 rpm), engine displacement (505 cid) and in its stereo (505-watt Infinity sound system).

With help from Chrysler Group's Performance Vehicle Operations, the changes from the '03 Ram made to the new SRT-10 number 165. Some of those changes resulted in an even meaner-looking exterior, while others transformed the SRT-10's interior and handling from trucky to sporty-bordering even on sports car. More than one engineer said the project was "like building a Viper with a truck body.'' With 500 horses under the hood of the SRT-10, we understand what they're talking about.

Dodge senior manager of design Dennis Myles said designing trucks is the best assignment you can get, and not just because trucks have taken over as the big moneymakers for automakers.

"I love the challenge that while everything we do here design-wise needs to look good, there's a rationale behind it,'' Myles said. "It's all about functionality throughout the vehicle.''

Myles declares the new Ram SRT-10, with its '04 Durango sibling, to be the most rewarding project of his career, more so even than his work with Lamborghini, back when Chrysler owned the Italian company.

Designing trucks differs from doing a typical coupe or sedan, in which most buyers seek attractive looks, a comfortable interior and a decent price. Today's truck guy demands more talents from his vehicle, for daily driving as well as for play and work duty.
