The 3900 V-6, the latest in GM's longstanding family of 60-degree V-6 engines. The 3900 will be the first GM overhead valve engine to use variable valve timing, and it will be GM's first V-6 to use DOD. Its first application will be on the '05 Pontiac G6. d

GM is also showcasing a new Ecotec 2.4L variant, which brings both larger displacement and variable valve timing to the Ecotec modular family. The Ecotec 2.4L, with 170 hp and 170 lb-ft of torque, will debut on the all-new '05 Chevrolet Cobalt.

Cammer Engines Showcase Power, Versatility, And PersonalityIn addition to hot, new F-150s and a tease of the next-generation Mustang, Ford is taking the wraps off three extreme-performance project vehicles powered by Ford Racing Performance Parts' (FRPP) all-new 5.0L Cammer V-8 crate engine. The new powerplant will be available through dealers or warehouse distributors beginning in 2004.

The '53 FR100 Panel Truck project is a logical successor to last year's FR100 pickup at SEMA. The FRPP '53 F-100 Panel Truck painted in UPS livery features an all-aluminum, overhead-cam, four-valve supercharged V-8, creating a full 5 liters of piston displacement; forged crankshaft with six-bolt mains and Manley "H-beam" connecting rods; and a specially reinforced block in the crankcase web areas for high-torque loads.

The Ranger Performance Concept is a Super Cab two-wheel-drive model with a 3.0L V-6 engine and five-speed automatic transmission, plus a Ford Racing supercharger good for 230 hp and 260 lb-ft of torque. A Ford Racing lowering kit, 13-inch Brembo brakes, high-performance air filter element, and FR500 18x9-inch aluminum wheels from the Mustang complete the package.

Diesel Drags?!Americans race everything from hermit crabs to lawn mowers. Now even diesel pickups have an organized way to compete in quarter-mile drag racing. Thanks to the Diesel Hot Rod Association (DHRA), an organization formed to promote and advance diesel-engine motorsports, bracket-style e.t. racing is now accessible for owners of Ford Powerstroke, Dodge Cummins, and GM Duramax light-duty diesel trucks. One recent diesel event was Weekend on the Edge 2003, held at Rocky Mountain Raceway near Salt Lake City and sponsored by diesel-performance specialist, Edge Products.

Race day attracted about 40 trucks and a number of diesel-powered cars to Rocky Mountain Raceway. Smoky burnouts, belching diesel smoke, and four-wheel-drive pickups making low-14-second passes characterized the action. (Running in 4WD helped the trucks hook up off the line and get maximum power to the ground.)

The racing highlight was Nathan Wright of Boise, Idaho, setting Street Diesel class records for both time and speed with a pass of 12.491 at 109.64 mph in his '01 Dodge. His Cummins is built with twin turbos, big injectors, and an Edge Comp-engine control module. Street Diesel is limited to street-legal SUVs and trucks containing engines as big as 450 ci, having a maximum of two commercially available power-adders (turbo, nitrous, propane), and running 12-second e.t.'s and slower. The DHRA Big-Dawg Modified Diesel class is for 10.00- to 11.99-second trucks, with tube frames and racing fuel acceptable.

DHRA racers smoke it out in regional competition throughout the country. Series champions in each DHRA regional division are awarded the prestigious Rudy trophy - a 6-inch-tall bust of Rudolph Diesel - at season's end.
