Bentley Arnage
The Bentley Arnage is a full-size luxury car manufactured by Bentley Motors in Crewe, England, from 1998 to 2009. The Arnage and its Rolls-Royce-branded sibling, the Silver Seraph, were introduced in the spring of 1998. They were the first entirely new designs for the two marques since 1980. In September 2008, Bentley announced that production of the model would end during 2009. Development Following an uplift in sales for all of Rolls-Royce, and a resurgence of the Bentley marque, the then-owner, Vickers, set about developing a new model to replace the derivatives of the Rolls-Royce Silver Spirit/ Bentley Mulsanne which it had been selling since 1980. In a complete switch from tradition, these new cars would have engines provided by a third-party vendor, and bodies built at the Crewe factory. A number of potential engines were examined, including the GM Premium V engine and the Mercedes-Benz M119 engine, before, in late 1994, Vickers selected a pair of BMW power plant ...

Bentley Continental R
The Bentley Continental R is a luxury coupé manufactured by British automobile manufacturer Bentley Motors from 1991 to 2003. It was the first Bentley to feature a body not shared with a Rolls-Royce model since the 1965 S3 Continental and was the first to use the GM 4L80-E transmission. The Continental R was the fastest, most expensive, and most powerful Bentley automobile of its day. It was also the most expensive production car in the world at its introduction. A convertible derivative, called the Bentley Azure, was launched in 1995.

Bentley Turbo R
The Bentley Turbo R is a high-performance automobile which was produced by Bentley Motors Limited from 1985 to 1999. The "R" stood for "roadholding", to set it apart from its predecessor. It initially inherited the turbocharged engine from the Mulsanne Turbo and also sported a retuned suspension and wider tyres on aluminium alloy wheels, a first for a Bentley. From the 1987 model year (20,000 series chassis numbers), however, the Turbo R's V8 engine was retuned with fuel injection for added torque. ''Motor Trend'' called the Turbo R "the first Bentley in decades deserving of the famous name" in their review of the car on its introduction to the United States in 1989. History The suspension changes, though seemingly subtle, transformed the soft and less than well-controlled ride of the Mulsanne Turbo into that of a real performer.Wood, p. 142 Development on improving handling had already begun when Mike Dunn was appointed engineering director in Crewe in February 1983, but inste ...

Headquartered in Crewe, England, the company was founded by W. O. Bentley (1888–1971) in 1919 in Crickle ...'s "entry-level" offering from 1984 until 1992. Distinguished mainly by a wire-mesh grille radiator instead of vertical slats, the Eight also had somewhat less equipment than the similar Mulsanne on which it was based. This brought the introductory price to under the psychologically important £50,000 mark at the time of introduction, £6,000 less than the Mulsanne. A firmer suspension offered slight handling improvements. The Eight was so popular that sales expanded from the original UK market to Europe and the United States. Model specification The Eight was introduced with cloth upholstery, steel wheels, and a mesh grille that was simpler than the slatted grille of the Mulsanne. Fuel injection ...

Chevrolet Avalanche
The Chevrolet Avalanche is a four-door, five- or six-passenger pickup truck that was manufactured by General Motors. The Avalanche was a hybrid between the Chevrolet Suburban SUV and the Chevrolet Silverado pickup truck, sharing the chassis with the Suburban. Unlike a typical pickup truck where the bed is mounted separately from the cab on the frame, the bed of the Avalanche was integrated with the cab body. It also featured a "midgate" behind the second row of seats that could be folded down, with the seats, to create a longer bed area. The Avalanche was produced across two generations starting in 2001 and ending in 2013. Breaking with a long-standing tradition, the Avalanche was not available as a GMC, but only as a Chevrolet. Instead, Cadillac would sell a re-badged Avalanche; however, the midgate design would be adapted for use on the GMC Envoy XUV and Hummer H2 SUT. __TOC__ First generation (2001–2006) The Avalanche was launched in September 2001 as a 2002 model on ...
