MG Rover Group, EcoGas Systems Limited and Landi Renzo S.R.L. have jointly developed an optional aftermarket Liquefied Petroleum Gas (LPG) conversion initially for new and used 1.8-litre Rover and MG cars. Utilising the more widely available 1.8-litre K Series engine built by Powertrain Limited at Longbridge, the converted Rover and MG cars can switch between petrol and LPG at the touch of a button.
