The Chrysler 6.1L HEMI is a 6,059 cc, 90‑degree V8 petrol engine produced between 2005 and 2010. It features a cast iron block, aluminium heads, single overhead camshafts (SOHC), and a hemispherical combustion chamber design. This configuration delivers robust, linear power, with outputs rated at 336 kW (425 PS) and 569 Nm of torque.
Fitted exclusively to high-performance SRT models like the Charger SRT8, Challenger SRT8, and Jeep Grand Cherokee SRT8, the 6.1L HEMI was engineered for drivers seeking uncompromising American muscle and track-capable performance. Emissions compliance was achieved through precise electronic fuel injection and catalytic converters, meeting stringent Euro 4 standards for its production period.
One documented engineering update involved the intake manifold design, revised in 2009 to improve airflow and reduce heat soak. This change, detailed in Chrysler Service Bulletin 08‑015‑09, addressed potential power inconsistencies under sustained high-load conditions and became standard on all 2009–2010 production units.
Production years 2005–2010 meet Euro 4 standards for applicable markets (VCA UK Type Approval #VCA/EMS/5683).
The Chrysler 6.1L HEMI is a 6,059 cc 90-degree V8 petrol engine engineered for high-performance sedans, coupes, and SUVs (2005-2010). It combines SOHC with hemispherical combustion chambers to deliver raw, high-revving power and a signature V8 exhaust note. Designed to meet Euro 4 standards, it prioritizes performance while maintaining relative drivability for its class.

The SOHC HEMI provides a broad, muscular torque curve ideal for rapid acceleration but requires strict adherence to 8,000-10,000 km oil change intervals using the specified 5W-20 viscosity to protect critical components. The single primary timing chain is generally robust but inspect for tensioner wear if a rattle develops. The 2009+ intake manifold (per SIB 08-015-09) offers improved thermal management. Fuel injectors and throttle bodies can develop deposits; periodic cleaning is recommended for optimal throttle response.
Oil Specs: Requires Chrysler specification MS-6395 (5W-20) (Chrysler Owner's Manual 2006).
Emissions: Euro 4 certification applies to all 2005–2010 6.1L HEMI engines for EU/UK markets (VCA Type Approval #VCA/EMS/5683).
Power Ratings: Measured under SAE J1349 standards. Ratings apply to standard SRT tune (Chrysler TIS Doc. V8-61L-01).

The Chrysler 6.1L HEMI was used exclusively in Chrysler Group's high-performance SRT models with longitudinal mounting. This engine received minor platform-specific calibrations for the Challenger versus the Grand Cherokee, but remained mechanically identical. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a machined pad on the front of the right (passenger) cylinder bank, just above the oil pan rail (Chrysler TIS V8-61L-01). The 8th VIN digit for 6.1L HEMI-equipped SRT vehicles is 'J'. Visually, the engine is identifiable by its large, cast aluminium intake manifold with "6.1L HEMI" cast into the plenum, distinctive coil-on-plug ignition, and bright orange valve covers. Critical differentiation from the 5.7L HEMI: The 6.1L has larger bore dimensions and unique intake/exhaust manifolds. The 2009+ intake manifold has a revised internal runner design per SIB 08-015-09.
The 6.1L HEMI's primary reliability focus is on maintaining precise oil pressure and quality, with elevated incidence of lifter or camshaft wear in vehicles subjected to aggressive driving or infrequent oil changes. Chrysler internal service data indicates that while the engine block is exceptionally robust, valvetrain components are sensitive to lubrication. Maintaining strict oil change intervals with the correct specification is critical for longevity.
