New hybrid powertrains for Jeep Renegade and Compass

Jeep has announced the introduction of new e-Hybrid (MHEV) versions of Renegade and Compass, with orders now open with first vehicles expected in the UK in March.

The new models debut an advanced hybrid system featuring a new 4-cylinder 1.5-litre turbo petrol engine, which delivers 130hp and 240Nm of peak torque, coupled with a new 7-speed dual-clutch automatic transmission.

The propulsion system includes a built-in 48 volt 15kW (20hp) electric motor delivering 55Nm of torque, equivalent to 135Nm at gearbox input level, which can propel the wheels even when the internal combustion engine is turned off. The new versions offer up to 15 per cent lower consumption and CO2 emissions than the previous petrol models.

New hybrid technology allows for full-electric propulsion at start-up, when travelling at low speeds, cruising and in parking manoeuvres.

The new 4-cylinder turbocharged engine has been designed to be the best fit for hybrid usage, to optimise thermodynamics, and therefore to save on fuel consumption. It operates on the Miller cycle which improves thermal efficiency and offers a high compression ratio (12.5:1), a new cylinder head with compact combustion chamber, dual variable valve timing and special ‘high-tumble’ intake ducts. Also new is the high-pressure direct injection system, operating at up to 350 bar. This petrol engine delivers an output of 130hp, while peak torque reaches 240Nm. A belt starter generator is also installed in the petrol engine, to guarantee fast and silent transitions when restarting.

The braking system of the new Renegade and Compass e-Hybrid includes the Intelligent Brake System which includes an ‘auto-charge’ feature using mixed regenerative braking to maximise the recovery of kinetic energy and improves efficiency.
