Rolls-Royce Dawn 6.6 V12 (571 Hp) Automatic

The Rolls-Royce Dawn is a luxury grand tourer convertible produced by Rolls-Royce Motor Cars. Introduced in 2015, the Dawn represents the brand’s entry into the market for high-end, open-top motoring. Based on the Rolls-Royce Wraith coupe, the Dawn shares its platform and powertrain but distinguishes itself with a fully retractable soft top and a focus on providing a serene and luxurious experience for all four occupants. The Dawn caters to a clientele seeking a blend of performance, opulence, and the freedom of open-air driving, solidifying Rolls-Royce’s position at the pinnacle of automotive luxury.

Rolls-Royce Dawn: A Modern Grand Tourer

The Dawn emerged as Rolls-Royce responded to a demand for a convertible offering within their lineup. While the Phantom Drophead Coupé served a similar purpose, the Dawn was designed to be a more driver-focused and contemporary alternative. It aimed to attract a younger demographic while maintaining the brand’s core values of handcrafted quality, bespoke customization, and effortless performance. The vehicle quickly became a significant model for Rolls-Royce, demonstrating the continued appeal of the luxury convertible segment.

Engine & Performance

At the heart of the Rolls-Royce Dawn lies a formidable 6.6-liter twin-turbocharged V12 engine, designated the N74B66A. This powerplant delivers 571 horsepower at 5250-6000 rpm and a substantial 604.8 lb.-ft. of torque between 1500 and 5000 rpm. The engine’s robust output translates to impressive performance figures, with the Dawn accelerating from 0 to 60 mph in just 4.8 seconds and achieving a maximum speed of 155.34 mph (250 km/h). The engine’s power-to-weight ratio stands at 223 hp per tonne, and the torque-to-weight ratio is 320.3 Nm per tonne, contributing to its effortless acceleration. The engine features direct fuel injection and a double overhead camshaft (DOHC) valvetrain, ensuring optimal combustion efficiency and power delivery. The engine displaces 6592 cm3 (402.27 cu. in.) and boasts a compression ratio of 10:1. The engine requires 11 liters (11.62 US qt / 9.68 UK qt) of engine oil.

Design & Features

The Rolls-Royce Dawn is a four-seat cabriolet with a 2+2 seating configuration. Its exterior design is characterized by flowing lines, a long hood, and a short rear deck, embodying the classic proportions of a grand tourer. The fully retractable soft top, available in a range of colors, is a key design element, transforming the car’s character from a luxurious coupe to an open-air convertible in seconds. The interior is meticulously crafted with premium materials, including fine leather, wood veneers, and polished metal accents. The Dawn offers a high level of customization, allowing owners to personalize virtually every aspect of the vehicle to their preferences.

Modern features abound, prioritizing passenger comfort and safety. The Dawn incorporates advanced driver-assistance systems, including ABS (Anti-lock braking system), and utilizes an electric power steering system for precise and effortless handling. The suspension system employs double wishbones at the front and an independent multi-link setup at the rear, both incorporating air suspension for a supremely smooth ride. Ventilated disc brakes are fitted on all four wheels, providing ample stopping power. The vehicle rides on 8.5J x 20 inch rims in the front and 9.5J x 20 inch rims in the rear, fitted with 255/45 R20 and 285/40 R20 tires respectively.
