[edit] 6G74 GDI

The gasoline direct injection version of the 6G74 was launched in April 1997 as the first GDI V6 engine ever produced. It differed from the basic 6G74 in many ways apart from its unique fuel injection system — it had a crown-curved rather than flat combustion chamber, upright intake ports rather than angled, and a 10.4:1 rather than 10.0:1 compression ratio. Mitsubishi claimed 30% better fuel economy, a 30% reduction in emissions, and higher power outputs than Diesels.^[1]
