2009 Bentley Arnage

The 2009 Bentley Arnage is a luxurious grand tourer known for its powerful engine, opulent interior, and stately presence. It was offered with a 6.75-liter twin-turbocharged V8 engine producing around 500 horsepower and 738 lb-ft of torque (depending on the specific model variant, such as the Arnage T or Arnage R). The only transmission option was a 6-speed automatic transmission. Owners often praise the Arnage for its comfortable ride, powerful engine, and handcrafted interior.
