In January 2012, Proton was acquired by DRB-HICOM, a Malaysian conglomerate in a transaction between Khazanah Nasional and DRB-HICOM which totalled RM1.2 billion. The Proton Prevé, the company's latest saloon car was unveiled on 16 April 2012. It became the first Proton car, and to an extent, the first Malaysian car to be awarded the full 5-star safety rating in the Australasian New Car Assessment Program (ANCAP) of Australia and New Zealand. In December 2012, Proton acquired all of Petronas' E01 engine technologies in addition to associated technology patents at a cost of RM 63 million. The deal encompassed a family of naturally aspirated and turbocharged 1.8, 2.0 and 2.2-litre engines to complement Proton's own CamPro 1.3L N/A, 1.6L N/A and 1.6L turbo engines.
