Infiniti Q45

The Infiniti Q45 is a fullsize luxury car and serves as the flagship of Nissan's Infiniti marque. It is a rear wheel drive luxury sedan powered by a V8 engine. The original Infiniti Q45 was based on the Japanese-market Nissan President (the flagship of the entire Nissan lineup at the time), but later generations were based on the lower-end Nissan Cima. The Q45 competes most directly with the Lexus LS, Cadillac DTS, Lincoln Town Car and Mercedes-Benz S-Class.

The Q45 was completely redesigned for 2002, now based on the new platform shared by both the Cima and the President. 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 — just 1129 were sold in the United States for all of 2005.

The current Q45 has received praise from Car and Driver, Edmunds and Consumer Guide. Low sales are attributed not to the car’s overall quality or performance, but to lack of advertising and the debatable prestige of the Infiniti name.

The 2003 was given a number of under the skin upgrades including a new security system, a numerically higher final drive ratio, reprogrammed TCU, and during the year, a satellite radio option. The CD player was now a one at a time feed into the dash.

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 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.
