The Flying Spur measures 5,316 mm in length, 2,013 mm in width, and 1,483 mm in height, with a generous wheelbase of 3,194 mm. It seats 5 passengers, though the rear middle seat is best for occasional use due to the transmission tunnel. The boot capacity is 351 litres. Ground clearance is 142 mm, which is adequate for Malaysian roads but requires care on steep driveways.

For the Flying Spur Speed plug-in hybrid, combined fuel consumption is rated at 10.7 litres per 100 km (WLTP), with a total driving range of up to 829 km on a full tank and full battery. The 25.9 kWh battery provides about 76 km of pure electric range. It supports 11 kW AC charging, taking approximately 2 hours and 45 minutes for a full charge. Non-hybrid V8 and W12 variants have higher fuel consumption typical of high-performance luxury sedans.

Routine maintenance for a Bentley Flying Spur typically costs between RM 5,000 and RM 10,000 per service in Malaysia. Major services involving brake pad replacement, transmission fluid change, or thorough inspections can cost RM 20,000 or more. The recommended service interval is every 15,000 km or once a year, whichever comes first. Due to Malaysia's hot and humid climate, owners should pay extra attention to the air conditioning system and electronic components.

The Flying Spur offers an extensive range of customization through Bentley's Mulliner division. Standard exterior colors include 101 options ranging from classic British Racing Green to bespoke shades. Interior choices include 22 leather colors, 11 interior schemes offering up to 700 leather configurations, 8 wood veneer options, and 3 trim styles. Available colors include Liquid Amber, Dark Burr Walnut, Tamo Ash, and many others. For ultimate exclusivity, Mulliner Bespoke allows customers to create completely unique colors and finishes.

The Bentley Flying Spur competes in the ultra-luxury sedan segment against several prestigious rivals. Its primary competitors include the Rolls-Royce Ghost (priced from RM 3.03 million to RM 3.72 million), which offers even greater exclusivity. The Mercedes-Maybach S-Class is another competitor, priced around RM 1.99 to 2.4 million. The Lexus LS is a more affordable alternative in the luxury sedan space, priced from RM 1.25 to 1.53 million. The Flying Spur distinguishes itself with its unique blend of performance, handcrafted luxury, and the ability to be both chauffeur-driven and driver-owned.

The Bentley Flying Spur typically comes with a 3-year unlimited mileage manufacturer's warranty. For the Flying Spur Speed plug-in hybrid, the battery and hybrid components are covered under the same warranty period, though buyers should confirm specific terms with Bentley Kuala Lumpur. Bentley also offers aftersales service packages that include scheduled maintenance. For the most current warranty details, prospective buyers should consult directly with authorized Bentley dealers in Malaysia.
