In the world of motorsport, energy efficiency has become an increasingly relevant topic, especially with the rise of environmental awareness and the need to reduce carbon emissions.
However, there is a segment of vehicles that, while impressive in terms of luxury and performance, sit at the opposite end of the efficiency spectrum.
The cars we will look at today, which include iconic brands such as Bugatti, Bentley and Rolls-Royce, stand out for their exquisite design, exceptional performance and luxurious amenities, but also for their notable fuel inefficiency.
By examining the least efficient models by size class according to EPA ratings, we delve into a world where prestige and power take precedence over sustainability and energy efficiency.
Two seater: Bugatti Chiron Pur Sport![]()
This supercar is synonymous with extreme power and luxury, but with remarkably high fuel consumption. Its W16 engine and focus on pure performance make it one of the least efficient in its category.
Minicompactos: Bentley Continental GTC![]()
A luxury cabriolet that offers exceptional performance and comfort, but with limited fuel efficiency due to its heavy weight and powerful engine.
Compactos: Mercedes-Benz AMG GT 63 4matic Plus![]()
Although it offers an exciting driving experience, this luxury sports car has high fuel consumption, especially in urban environments.
Medianos: Bentley Flying Spur y Cadillac CT5 V![]()
These luxury sedans provide comfort and power, but their fuel efficiency is low compared to other vehicles their size, primarily due to their large engines and focus on luxury and performance.
Grande: Rolls-Royce Ghost, Rolls-Royce Ghost Negro Insignia, Rolls-Royce Ghost Extended, Rolls-Royce Phantom y Rolls-Royce Phantom Extended![]()
These Rolls-Royce models are known for their opulence and luxury, however, it is their large size, weight and powerful engines that contribute to their inefficiency in terms of fuel consumption.
SUV: Lamborghini Urus Performante![]()
Despite being one of the fastest and most powerful SUVs on the market, the Urus Performante sacrifices fuel efficiency for performance and speed, making it one of the least efficient in its category.
SUV’s: Rolls-Royce Cullinan y Rolls-Royce Cullinan Insignia negra
These ultra-luxury SUVs from Rolls-Royce, while offering an unrivaled driving experience and high-end amenities, are notoriously fuel inefficient, due to their massive size and large displacement engines.
What are the key factors that make them less efficient?![]()
The cars mentioned are considered the least efficient, according to the EPA (US Environmental Protection Agency) mainly due to several key factors:
- Size and weight: Vehicles like the Rolls-Royce Phantom and the Bentley Flying Spur are extremely large and heavy. This means they need more energy (in the form of fuel) to move, which reduces their fuel efficiency.
- Engine power: Many of these cars, such as the Bugatti Chiron Pur Sport and the Lamborghini Urus Performante, are equipped with extremely powerful, large-displacement engines. These engines consume large amounts of fuel, especially under hard acceleration, resulting in poor fuel efficiency.
- Design focused on performance and luxury: These vehicles are designed with a focus on maximum performance and luxury, rather than energy efficiency. For example, the Mercedes-Benz AMG GT 63 4matic Plus is optimized to offer a sporty, high-speed driving experience, which typically reduces fuel efficiency.
- Aerodynamics: Although some of these vehicles, such as the Bentley Continental GT, have an aerodynamic design, their large size and the need to accommodate powerful engines often result in lower aerodynamic efficiency compared to smaller, lighter vehicles.
- Fuel Efficiency Technology: These cars tend to use fewer of the advanced fuel-saving technologies found in more efficient vehicles. Although they may have some modern features, the priority is given to performance and luxury, rather than efficiency.
- Consumer Preference: The market segment these vehicles target (high-end luxury and high-performance sports cars) often values performance, prestige and luxury features more than fuel efficiency.
The lower efficiency of these vehicles is due to their design and construction geared towards extreme luxury, high-end performance and driving sensations, rather than efficiency and fuel economy.
