Rolls-Royce Dawn Black Badge: 4.8 secondsFollowing its introduction in 2017, the Dawn Black Badge was only produced for a few short years before it reached the end of the line in 2023 (Rolls-Royce ceased sales of the Dawn in the U.S. in 2021). But that was all the time the high-performance convertible grand tourer needed to leave its mark as not only one of the fastest Rolls-Royce cars ever made, but also one of its most powerful models.Based on the seventh-generation BMW 7 Series platform, the Dawn Black Badge derived motivation from a twin-turbo 6.6-liter V12 that generated 593 horsepower and 620 lb-ft of torque, up from 563 hp and 605 lb-ft in the standard car. The engine is mated to an eight-speed automatic transmission that directs output to the rear wheels, allowing a 4.8-second zero-to-60 mph time and a top speed of 155 mph. That's the same speed and manufacturer-estimated acceleration time as the regular Rolls-Royce Dawn.Rolls-Royce Black Badge Cullinan: 4.5 secondsBefore electrification gained momentum, V12s were a Rolls-Royce staple, and the mighty motor will be around until 2030 when all current Rolls-Royce models will be electric only. That means even after its recent refresh, buyers with deep enough pockets can still order a Rolls-Royce Black Badge Cullinan with a V12. It's the same engine found in the Rolls-Royce Ghost and Black Badge models, with output remaining the same at 592 horsepower and 664 lb-ft of torque. That's routed to the all-wheel drive system through an eight-speed automatic transmission, resulting in an estimated zero-to-60 time of 4.5 seconds and a top speed of 155 mph.Strong performance aside, the Cullinan reputedly prioritizes ride refinement, with its self-leveling air suspension, continuously adjustable electronically controlled shock absorbers, and massage seats combining to deliver a smoother, more consistent experience. Rolls-Royce also offers a rear-wheel steering system that makes the ultra-luxury SUV more maneuverable in tight areas by reducing the turning circle and increasing the steering response.Rolls-Royce Wraith, Wraith Black Badge, and Wraith Black Arrow: 4.4 secondsAs you might have observed, Black Badge Rolls-Royce cars typically make more power than their standard siblings. However, when it comes to the Wraith, the engine keeps the same horsepower regardless of grade. That means there's an astounding 624 horsepower on tap no matter whether it's the standard Rolls-Royce Wraith, Wraith Black Badge, or Black Badge Wraith Black Arrow, which honors the eight-wheeled Thunderbolt car that broke the land speed record by achieving a top speed of 357.497 mph in 1938. All three cars use a twin-turbocharged 6.6-liter V12 engine that funnels output to the wheels through an eight-speed automatic transmission, propelling them to a 155-mph top speed. As for acceleration, the Wraith Black Badge and standard Wraith coupe can do an impressive 4.4-second zero-to-60 mph sprint, while the Black Badge Wraith Black Arrow is reported to accelerate off the mark in a little over 4 seconds. The Wraith is based on the same platform as the Rolls-Royce Ghost, which itself is a modified seventh-gen BMW 7 Series platform. However, in their bid to improve the coupe's agility, Rolls-Royce engineers decided to rest its body on a shorter wheelbase and also equipped it with a wider axle than the Ghost offers.
