 The G20 was a badge-engineered version of the Nissan Primera, but because Infiniti was pitched as a premium brand, it featured a high level of equipment compared to its European and Japanese relatives.The only engine available was the 2.0 litre SR20DE Inline 4-cylinder; in Europe this was the top-of-the-line engine for the Primera lineup.5-speed manual and 4-speed automatic transmissions were both available, with the 5-speed being praised as "one of the best in the business."
