Jeep is an American off-road brand, founded in 1941 for military use (Willys MB). Jeep is part of the Stellantis group (formerly FCA). Jeep specialises in four-wheel-drive off-roaders and crossovers. Jeep shares engines with Dodge and Chrysler. The Jeep Trackhawk is the flagship, powered by the Hellcat-family supercharged Hemi V8. Jeep's petrol range comprises the Pentastar V6, the Hemi V8 and turbo four-cylinders.
Protection on modern Jeep models uses Tricore, so Bench is required for the top models. The Jeep community in the US offers a large pool of ready-made Stage files for off-road use. In Europe the Jeep community is growing thanks to the diesel versions. High-output Jeep models are the top-spec Grand Cherokee and Wrangler, with solid headroom for Stage 1.
Aisin transmissions feature on the compact crossovers. The ZF 8HP TCU rarely needs calibration below Stage 1+. Jeep uses the ZF 8HP on premium models.
