Local Motors Births A Concept

"What the heck is that thing?"

We heard that over and over throughout the afternoon as we made our way down a desert trail east of Phoenix, Arizona. What people saw on a rocky wash trail frequented by dirt bikes, quads, and 4WDs was the Local Motors prototype Rally Fighter, and we were putting it through some high-speed desert running and some low-speed rock bumping.

It was a modern-day concept that spawned a modern-day vehicle. The Rally Fighter is an off-road vehicle, yet an on-road vehicle. More on this after we tell you a little about this car company.

Local Motors is a fairly new car company that was started with the idea of creating a collaborative community of car designers, engineers, and enthusiasts who could come together to create unique new car designs. They hold online community design contests, and there, other car nuts join to share, learn, and grow new vehicle concepts.

Beyond that, they have a goal to turn some designs into working rigs sold in 2,000-vehicle production runs. Their intent is to offer innovative designs produced in small, highly efficient factories in the USA. Once a car design is adopted by the community, and it's decided it will be produced, a prototype is built. Once the design wrinkles are ironed out, the design can go to production in one of the new micro factories.

The Rally Fighter was conceived and designed by Local Motors community member Sangho Kim and is currently being built in the first micro factory in Phoenix. Local Motors describes the Rally Fighter as a vehicle designed for the American Southwest. It's got capability both on-road and off, and will be street licensed. It's what you might commonly refer to as a truggy-style rig, with long-travel A-arm suspension up front backed with a linked solid axle rear setup. The chassis sports 18 inches of front wheel travel and 20 inches in the rear and is built to have a dual ride height with the choice of 275/70R17 (high ride height) or 265/50R20 (low ride height) Goodyear MTR tires. The car is wrapped in a fiberglass body with functioning hood and doors, and has the creature comforts of air conditioning and heating.

  • We followed the wash trail downstream and the 2WD Rally Fighter did some downhill rock-crawling with little issue. The generous belly clearance allows for lots of suspension travel and allowed us to bump over some decent-size rocks. Final weight of the car is approximately 3,500 pounds.

  • Tucked into the powdercoated tubular chassis is the GM 6.2L emission legal LS3 sold as the turn-key E-rod package. This efficient engine pumps out about 430 hp and about 450 lb-ft of torque. The engine is mounted well rearward of the front tires to help even the weight distribution. Behind the motor resides a 4L85E four-speed auto transmission.

  • The rear axle is positioned using a three-link with Watts link to control side-to-side motion across about 20 inches of travel. The Rally Fighter uses a Ford 8.8 disc-brake axle filled with 3.55:1 gearing and a factory limited-slip differential. You can see the elevated dual exhaust dumps, and the battery sits centered, just forward of the rear bumper.

  • The braking is setup with a four-wheel anti-lock system. Both the 13-inch rotors used up front and 13.7-inch rotors used in the rear are Ford pieces, as are the front (dual piston) and rear (single piston) calipers. Brake booster, master cylinder, and pedal assembly are all from Ford parts stock, as well.

  • A 1.75-inch tubular chassis is tucked under the fiberglass skins and the Rally Fighter is setup to easily transform from low ride height to tall ride height, and vice versa. Dual upper coilover mounts exist in the front and rear to allow the upper shock eye to be repositioned fairly quickly.
