The Rally Fighter is an American automobile manufactured by Local Motors and introduced in 2009.

The Rally Fighter is street legal in all 50 US states.[2][3][4][5]

Specifications

Rear view

The Rally Fighter is powered by a front-mid mounted 6.2 L GM LS3 V8 that produces 430 hp (321 kW; 436 PS) at 5,900 rpm and 424 lb⋅ft (575 N⋅m) of torque at 4,600 rpm. Power goes to the rear wheels through a 4-speed GM 4L85-E automatic transmission. The suspension utilizes “Double A-Arms” in the front end and a Solid Ford 9-inch axle using either a “Watts-Link” to locate the axle laterally and a “3-Link” with Trailing arms to locate the axle vertically in the rear or utilized a “Triangulated 4-Link” rear control arm setup to locate the axle in every direction. both using coil springs and “Coil-over” Long travel telescopic shock absorbers. This gives it 16 inches of suspension travel in the front and 20 inches in the rear.[6] It also features a fiberglass body to save weight. In the interior, the Rally Fighter is equipped with standard 4-point harness seat belts, a full roll cage and Recaro seats, as well as amenities such as air conditioning, stereo and power windows.[7]

Build process

The Rally Fighter used an assembly process where the buyer of the car went to one of Local Motors' micro-factories to assemble their car with help from a team of Local Motors employees. This also allowed the Rally Fighter to be titled as a kit car or component car in the United States.[8] The Rally Fighter is street legal in all 50 states and upwards of 50 cars have been produced.[2]

Crowd sourcing

The Rally Fighter is an open-source vehicle.[7][9] The Rally Fighter is believed to be the first production vehicle designed through crowdsourcing, the process of drawing input from a global community of interested people via the Internet. The winning design was submitted by Sangho Kim of Pasadena, California, and is inspired by a P-51 Mustang fighter plane. It was chosen through a vote in 2009 by a community of people on the Internet. Using this method, the car was developed from start to finish in 18 months.[10]
