Jeep is part of the Stellantis group (formerly FCA). Jeep specialises in four-wheel-drive off-roaders and crossovers. Trail Rated is Jeep's signature certification for off-road capability. The Jeep Avenger is a compact electric car on the Stellantis platform. Jeep 4xe is the badge for the brand's PHEV models (Wrangler 4xe, Grand Cherokee 4xe). Jeep PHEV variants combine a turbo engine with an electric motor.
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. Protection on modern Jeep models uses Tricore, so Bench is required for the top models. Top-tier Jeep Trackhawk/SRT engines sit at the power ceiling of American SUVs; the gain is significant.
Aisin transmissions feature on the compact crossovers. Jeep uses the ZF 8HP on premium models. The Trackhawk and SRT come with a reinforced ZF 8HP.
