Light, quick and nimble, the Jeep 4SPEED concept is the latest in a line of lightweight Easter Jeep Safari concepts. Built “4SPEED,” this latest lightweight concept, following the popular Pork Chop concept in 2011 and Stitch concept in 2013, bolsters Wrangler’s off-road capability and performance through extensive weight savings, and showcases the all-new 2.0-liter turbocharged I-4 engine.
On the exterior, the Jeep 4SPEED concept features custom weight saving measures including a carbon fiber hood, high-clearance carbon fiber fender flares and a carbon fiber rear tub with perforated aluminum panels. The 4SPEED concept boasts a sleek side profile courtesy of a raked windshield, elongated door openings and an aggressively swept back custom cage. The rear of the concept utilizes custom, lightweight bodywork, and because of the combined weight savings, 4SPEED’s ride height is two inches higher than a stock Wrangler.
In addition to being lightweight, overall length has been shortened by 22 inches while leaving the wheelbase at its stock length, resulting in increased approach and departure angles.
For even more capability, Jeep 4SPEED features Dana 44 front and rear axles with a 4.10 gear ratio and 18-inch lightweight monoblock wheels wrapped in 35-inch BF Goodrich Mud Terrain tires.
The interior features a customized instrument panel, and re-trimmed front seats, while the rear seats have been removed and a welding curtain has been repurposed as a bikini top. The floor has been bedlined and the foot wells have been replaced with perforated aluminum panels.
The Jeep 4SPEED is powered by a 2.0-liter I-4 turbocharged engine, mated to an eight-speed automatic transmission.
