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 tires on 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.
The Bentley 8 Litre was a luxury car based on the largest rolling chassis made by Bentley Motors Limited at Cricklewood, London.
 Announced 15 September 1930, it was also the last completely new model by Bentley before the company's financial collapse and forced sale to Rolls-Royce Limited; a 4-Litre engine in a shortened chassis was announced on 15 May 1931.
 Intended to provide the basis for a super-luxury car for very wealthy buyers, the 8 Litre chassis was introduced a year into the Great Depression.
 Sales of the 8-litre were too slow to turn the company's finances around and, less than nine months after the 8-litre's introduction, Bentley Motors was placed into receivership.
The Bentley Mulsanne is a performance luxury car which was produced by Bentley Motors Limited from 1980 until 1992, though derivative models like the Continental T and Azure continued in production into the 2000s.
 The name "Mulsanne" is derived from Bentley's motorsport history, which included five victories at the 24 Hours of Le Mans between 1924 and 1930 — the 'Mulsanne Straight' being the stretch of the Le Mans racecourse where cars reach their highest speeds.
The Silver Wraith was the first post-war Rolls-Royce.
 It was made from 1946 to 1958 as only a chassis at Rolls-Royce's former Merlin engine plant, their Crewe factory, alongside the shorter Bentley Mark VI.
 The Bentley too was available as a chassis for coachbuilders but also for the first time could be bought with a Rolls-Royce built standard steel body.
The Bentley 4 Litre was a motor car built on rolling chassis made by Bentley Motors Limited.
 The 4 litre chassis was conceived and built in a failed attempt to restore Bentley to a good financial state.
 Announced 15 May 1931, it used a modified four litre Ricardo IOE engine in a shortened 8 litre chassis at two-thirds of the price of the 8 Litre in an attempt to compete with the Rolls-Royce 20/25.
 Instead, Bentley went into receivership shortly afterward, from which it was purchased by Rolls-Royce Limited.
Rolls-Royce SZ and Bentley SZ refers to several different Rolls-Royce and Bentley car models produced 1980–2003 by Rolls-Royce Motors (1980–1999) and Bentley Motors Limited (1998–2003).

The Bentley Azure is a large, four seater convertible built by Bentley Motors Limited at its factory in Crewe, England.

 According to 2009 research by internet company Yahoo!, the Azure is the fourth most fuel consuming car on sale in the United Kingdom.
