The Q45 came back completely redesigned for 2002. This Q45 focused on performance again with a new 340 hp (253 kW) 4.5 L VK45DE V8 engine, gatling-gun inspired HID headlights, and sharper styling. The car features a 5-speed automatic transmission with overdrive. Despite good reviews, sales remained poor.

Low sales are attributed not to the car’s overall quality or performance, but to lack of advertising and the arguable prestige of the Infiniti name.


The Q45 received a number of upgrades for the 2005 model year, including new front and rear fascias, restyled hood and grille, restyled trunk lid, new headlight design, integrated fog lights and LED taillights. Inside were new contoured double-stitched seats, white luminescent gauge markings, chrome accents and dark maple trim. 2005 upgrades also included a recalibrated transmission and new 17" alloy wheels.


The following features are standard in the Infiniti Q45: all-leather interior, power sunroof, 8-way power front seats, remote keyless entry, rain-detecting wipers and side curtain airbags. Standard electronics include: CD, 8 Bose speakers, trip computer, rear camera parking sensors and a voice-activated navigation system. The 2002 Q45 was the first vehicle to ever offer voice-activated navigation controls.

The car seats five and has a base price of US$56,200.
