The Rover G series is a water-cooled and turbocharged inline four-cylinder diesel engine with common-rail injection.
[4] The first production G-series engine was an 8-valve introduced in the 2007 ICML Rhino[5] in collaboration with MG Rover and additionally used in the 2012 Chevrolet Tavera Neo 3.
The engine, known as Galileo, spent three years in development prior to MG Rover Group’s collapse in 2005.
To achieve these targets, MG Rover Group engineers introduced a new cylinder head, valves, pistons and a Siemens engine management system using a common-rail system equipped with the latest injector technology available at the time to the L series' existing architecture, carrying over the cylinder block and sump.
However, due to ongoing throttle calibration throughout development, the engine was reportedly hard to start in cold conditions.
By using a fully electronic variable-geometry Garrett turbocharger resulting in a variation of boost pressure, when installed in a Rover 75 producing 100 kW, engineers reported that the engine "was fantastic...it flew and never missed a beat" whilst being driven at "full chat" to Sweden to sign off work on new brake control and electronic stability programs.
