The INFINITI I30 is a recipient of an all-new restyling for 2000. Two inches longer in wheelbase than the previous generation sedan, the 2000 INFINITI I30 boasts larger diameter wheels and tires, improved comfort features and a 3.0-liter powerplant producing 227 horsepower (a 37-horsepower bump compared to its predecessor). Through the addition of double-tipped platinum spark plugs in 2000, the INFINITI G20's engine power has been bumped to 145 (a 5-horsepower improvement compared to 1999). For 2000, INFINITI is celebrating its 10th year as a luxury brand. Marking the occasion, a limited Q45 Anniversary Edition model has been prepped with special badging as well as exterior and interior upgrades. An electronic navigation system has also been added as an option on the 2000 INFINITI Q45.
