Choosing the right engine is crucial for long-term satisfaction with a luxury vehicle, especially if you are looking for a car on the secondary market around four years old. Our recommendation is based on performance parameters, real-world fuel consumption, user feedback, and mechanical reliability. An interesting point about these British aristocrats is their completely different engineering approach – while Bentley opted for a weight saving of about 50 kg over the front axle for its V8, making it a surprisingly sharp and agile GT, the second-generation Rolls-Royce Ghost switched to a completely new, purely bespoke aluminum platform and tuned its massive V12 exclusively for perfectly silent pull from idle. Given that both of these recommended engines ended their original production phase in 2024 (before the arrival of modernized generations), they represent the best you can buy on the nearly-new used car market in this category today.
For the Bentley Continental GT, we recommend: 4.0 V8 (404 kW / 550 hp)
While the massive W12 engine is historically iconic for the British brand, for the 4th generation (from 2019 to 2024, which is no longer produced in this specification as new), the twin-turbocharged 4.0 V8 makes the most sense from both a user and service perspective. This engine, with 404 kW (550 hp) and 770 Nm of torque, guarantees excellent acceleration to 100 km/h in exactly 4 seconds. However, its greatest technical advantage is the significantly lightened front end, which gives the heavy car a top-tier willingness to turn, minimizes understeer, and makes it a much more playful driver's car. Thanks to the cylinder deactivation function at low load, it also brings surprisingly reasonable fuel consumption and a real highway range of over 750 km. In terms of overall reliability, the V8 engine is more accessible for mechanics and more service-friendly than the cramped W12 unit, but the main pitfalls in used cars are the complex cooling system and air suspension. How to detect faults: When inspecting the car, always check if the car is leaning to one side after being parked for a long time (a sign of air leaking from the bellows) and if the suspension compressor runs abnormally loudly or for too long after starting. Also, spend time clicking through the infotainment, where the software occasionally glitches. This engine is an absolutely ideal choice for active drivers who love more dynamic driving, want to hear the characteristic exhaust burble, and are looking for a grand tourer built for daily use.
For the Rolls-Royce Ghost, we recommend: 6.8 V12 (420 kW / 571 hp)
In the case of the second-generation Rolls-Royce Ghost (produced between 2020–2024, followed by the Series II facelift), the uncrowned king of the range is exclusively the twin-turbocharged 6.75-liter twelve-cylinder. This majestic unit provides 420 kW (571 hp) and a crushing 850 Nm of torque, which is available to the crew from just 1600 rpm. Instead of aggressive acceleration, its main weapon is a perfectly smooth torque curve, seamlessly transferred to the all-wheel-drive system. The technical gem of this car is the advanced "Planar" suspension with additional mechanical dampers on the upper wishbones, thanks to which the massive twelve-cylinder can silently swallow the road with the legendary "magic carpet ride" feeling. Although the engine itself is very robust in terms of long-term mechanical reliability and does not suffer from fatal defects, the car as a whole is an extremely complex mechanism riddled with electronics, where any repairs are astronomically expensive. How to detect faults: During a test drive, listen carefully for any unusual noises and watch the instrument cluster – if an error like "level control malfunction" appears or the car feels stiff when driving over bumps, you are in for very expensive air suspension service. Also, thoroughly test whether the rear-axle steering and the electric opening and closing of the heavy doors work flawlessly and quietly. This twelve-cylinder engine is a must for demanding clients who require absolute silence, luxurious majesty, and maximum isolation from the outside world during long highway journeys in total peace.
