The Infiniti Q45 is a fullsize luxury vehicle and serves as the main of Nissan's Infiniti marque. It is a back wheel drive luxury sedan powered by a V8 motor. The original Infiniti Q45 was based on the Japanese-market Nissan President (the main of the entire Nissan lineup at the time), but later generations were based on the lower-end Nissan Cima. The Infiniti Q45 competes most directly with the Lexus LS, Cadillac DTS, Lincoln Town Vehicle and Mercedes-Benz S-class.
The Infiniti Q45 was completely refactored for 2002, now based on the new platform shared by both the Cima and the President. This Infiniti Q45 focused on performance again with a new 340 hp (253 Kw) 4. 5 L VK45DE V8 motor, gatling gun inspired HID headlights, and sharper look-and-feel. The vehicle features a 5-speed automatic transmission with overdrive. Despite good reviews, sales remained poor — just 1129 were sold in the US for all of 2005.
The current Infiniti Q45 has received applause from Vehicle and Driver, Edmunds and Consumer Guide. Low sales are attributed not to the car’s overall class 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 safety system, a numerically higher final drive ratio, reprogrammed TCU, and during the year, a radio feature. The CD player was now a one at a time feed into the dashboard .
The Lexus LS (sold as the Toyota Celsior in Japan, Australia, and some other countries. ) is a V8-powered, back wheel drive luxury vehicle that serves as the main of Toyota's luxury Lexus division.
The UF10 I LS 400 was manufactured from 1989 to 1994. The model presented the Lexus nameplate to the US, and soon after won critical acclaim, becoming Wheels magazine's Vehicle of the Year and earning a place on Vehicle and Driver magazine's Ten Best list for 1990. The LS 400 was initially tailored to be presented as a standalone model for Lexus, but ultimately was sold alongside the ES 250, an entry-level luxury vehicle that was based on the Toyota Camry.
For the 1993 model year, the LS 400 (now designated as the UF10 II) was presented with larger brake rotors, traditional passenger's side front airbags, larger wheels and tires, and numerous other upgrades.
Presented in 1995, the UF20 III LS 400 was an evolutionary redesign of the LS and featured a new body that eliminated 300 lb from the previous vehicle. The wheelbase was increased by 1. 4 in, resulting in more dashboard and cargo room, yet the overall length of the vehicle remained at 196. 7 in. The durability of the brake system was enhanced as well.
